OIL SEAL FAILURE DIAGNOSIS

PROMOTIONAL ARTICLE ON BEHALF OF CORTECO

 

 

Oil Seal Failure Diagnosis

Often, when parts such as oil seals fail prematurely they are replaced and returned under warranty; however, in most cases the seal itself isn’t the reason the failure has occurred. In this guide, we will take you through the causes and how to avoid premature leaks and failures in the future.

Lip Leakage Diagnosis

Click for expanded chart

If the lip has worn out then this is often caused by the seal not being sufficiently lubricated before installation causing abnormally high temperature, the presence of foreign matter, disproportionate internal pressure or an excessively rough shaft surface. Similarly if when removing a seal, if the lip has hardened and there are visible cracks, you can be sure that this has again been caused by abnormally high temperatures, excessive internal pressure or insufficient lubrication. The cause for the abnormally high wear has occurred due to friction as the amount of lubricant was below the specified level and therefore did not reach the seal lip. Alternatively, insufficient lubrication can come from dry-wear conditions because the vehicle’s oil levels are low. Another sign of this is if the lip wear band is smooth and glossy.

Alternatively, if the lip has softened, then the main cause of this is the lip having the incorrect material required for the application. In order to prevent this from reoccurring make sure the correct seal is sourced for the specific application before installation.

If you notice the lip of the seal has worn unevenly then this is due to cocked seal installation or an excessive shaft offset. As before, both should be checked during installation but crucially before the vehicle is out on the road.

Installation errors tend to be a big factor in automotive parts failing prematurely. This is apparent if you can see that the lip of the seal is scratched, caused by improper assembly, improper handling, an incorrect shaft chamber or the presence of foreign matter entering the seal. The scratches are often caused by being assembled over burrs or other defects in the shaft chamber, the lip coming into contact with sharp metal parts during transit or storage or if the seal was handled with gloves contaminated with metal particles.

As stated improper handling can be a factor in causing a seal to fail prematurely, the tell-tale sign is the seal lip being swollen or soft. The swelling is caused by the lip being soaked in solvents or petrol before installation. Alternatively, if when removing a seal you see the fit trace is disconnected locally then the seal could have been deformed because of an improperly designed assembly jig or a gap in the press-fit occurred due to rough handling.

However, although problems during fitting can contribute to the part failing, other issues may be the key factor. If the lip’s waist (flex area) is broken, then this can be because of improper assembly but can also triggered by excessive internal pressure. Similarly if the lip is turned-under, the lip edge is severely worn and the wear band is concave then this is connected to an incorrect shaft chamber, improper assembly and excessive internal pressure meaning the oil seal area exceeded the maximum pressure it was originally designed for. To prevent this reoccurring, identify the maximum pressure for the seal and check it is compatible with the vehicle. However, if the lip edge is severely worn but there are circumferential grooves on the wear band then the cause is that the shaft finish was rougher than the specified range again this can be prevented by sourcing the correct part for the specific application.

Similarly, if the lip edge is severely worn and there are grooves or indentations on the surface. Foreign matter can affect the seal in many ways whether the cause is due to a shaft or seal that has been contaminated with foreign particles being used or the contaminants were embedded in the seal lip. The cause can be triggered when the seal is assembled in the presence of dirt and/or dust causing the contaminants to become embedded in the sealing lip. In addition, if the seal or the housing was assembled with silicone, the sealant will have contaminated the shaft or seal.

If, when removing a seal the garter spring has become disconnected then this has likely been caused by an incorrect shaft chamber or improper assembly, checking the installation can ensure you and you customers are happy with the finished job.

However, if there isn’t an obvious fault with the oil seal, the cause is often difficult to diagnose, but before you prematurely condemn a good seal first check if the shaft is scratched or the diameter is incorrect, if the shaft rotational direction does not match the helix on the seal, there is excessive shaft offset or runout, the shaft is worn or the seal has been installed incorrectly.

Press-Fit area leakage diagnosis

Below we identify four common causes of premature leaks due to incorrect handling/installation.

If the oil seal is cocked then this can be caused by an improperly sized bore diameter, incorrect shaft chamber or improper assembly jig.

Like with the lip leakage diagnosis if the oil seal is problem free, check if there is a scratched or an improperly sized bore or excessive bore surface roughness. Similarly if the seal OD is damaged or chafed the bore is often the cause. Ensure you check if there is an improper sized bore diameter, incorrect shaft chamber or improper assembly jig before installation.

All the causes mentioned can be avoided if the correct steps are taken when assembling, ordering and fitting a part.

ECOBAT TO EXHIBIT AT AUTOMECHANIKA B’HAM

ECOBAT TO EXHIBIT AT AUTOMECHANIKA B’HAM

PROMO ARTICLE ON BEHALF OF ECOBAT TECHNOLOGIES

There is a lot more to the ECOBAT group than meets the eye. Besides being Europe’s largest specialist battery distributor, it is also the world’s largest producer of lead and lead alloys, supplying battery manufacturers all over the world. As a result, more than 50 million batteries are produced containing its lead and alloys annually.

This specialism means that ECOBAT Technologies is also a global leader in metallurgical processes and R&D for battery plate construction enhancements, continually developing the use of alloys to improve battery performance, such as:

  • Cranking and Capacity
  • Cycle life
  • Charge acceptance
  • Reduced gassing
  • Operation in extreme temperature environments
  • Reduced corrosion

This commitment has led to many of the key technology advances and product patents, but the company also works with leading battery manufacturers, adding its expertise to their own.

In 2009 the group began investing in battery distribution, and today the division – ECOBAT Battery Technologies (EBT) –  supplies more than 2.5 million batteries to OEM and aftermarket customers, many of which will inevitably contain its advanced lead and alloys, ensuring optimum performance and product longevity. EBT is not simply a specialist battery supplier, it is part of a manufacturing and technology group with a battery specialist division.

In the UK, EBT is active in virtually all battery markets, with wide sector coverage and comprehensive product ranges with leading brands such as VARTA®, Lucas and Numax. The quality of the products, combined with a nationwide distribution network, focussed customer support and high stock availability, are all contributory factors to the success of the company.

To demonstrate all things EFB/AGM and encourage technicians to look to the future and benefit from the changing world of batteries, EBT is teaming up with long-term partner VARTA for this year’s Automechanika Birmingham.

As it has done previously, the company will also be using one of the event’s technical presentations – to be delivered from the Technical Training Hub in the show’s ‘Garage Quarter’ – to give technicians a glimpse of the future by addressing the realities of the growth in lithium battery technology and the responsibilities faced by workshops as the global trend for electric vehicles continues.

At the same time, current technology must not be overlooked as the market transitions from traditional to hybrid vehicles, which puts greater demands on the vehicle’s battery management system and requires vehicle specific repair solutions.

Technicians are at the front line, not only when it comes to diagnosing problems and making the repair, but also in educating motorists who are largely unfamiliar with this new technology. EBT will therefore be challenging them with the question: are they equipped for an electric future?

Back on its stand (H81), alongside the market-leading VARTA range, EBT will be displaying the formidable Lucas portfolio, as well as its very own Numax offering, to demonstrate the depth and breadth of products in its substantial armoury.

“Automechanika again provides us with the ideal occasion to connect with our customers and end-users, to help them gain a clear understanding of the challenges – and accompanying opportunities – that the latest technical developments present,” explains the company’s Sales Director, Paul Payne.

“Start/stop equipped vehicles, the continuing trend towards fully electric alternatives, environmental responsibilities and the wider opportunities outside of the traditional automotive sector are all points of interest that many visitors will want to discuss and for which EBT has many compelling solutions. We therefore look forward to welcoming visitors to both the technical presentation and our stand, to demonstrate how we can travel the road together and look forward with confidence to a bright future.”

TEXTAR BRAKE PADS ACHIEVE RESULTS IN AMS BRAKING TEST

TEXTAR BRAKE PADS ACHIEVE RESULTS IN AMS BRAKING TEST

PROMOTION ARTICLE ON BEHALF OF TEXTAR

Global OE friction manufacturer, TMD Friction, has proved the quality of its Textar aftermarket brakes in an AMS braking test that scored Textar above the competition and original equipment manufactured material (OEM).

An Audi A5 and VW Passat Variant test vehicles were loaded to the permissible gross vehicle weight along with two passengers. The car was brought to a standstill by braking from a speed of 100 km/h ten times in a row. The first and the tenth braking applications were evaluated to provide information about the characteristics of the brake pads when they were cold and hot.

Textar competed against three competitor brands and the respective OEM material, with both test vehicles equipped with ex works. Overall, Textar achieved the best results compared to the competitors’ products and the VW Passat Variant scored even better results than the OEM material. The Audi A5 with Textar brakes performed identical to the OEM material, for cold and hot braking, and was the most stable performer in comparison with its competitors. The difference between the first and tenth braking application was only 0.2 m, the same as the amount achieved by the brake pad fitted as part of the original equipment from the manufacturer. The biggest deviation by a competitor was 2.8 m.

For cold braking, Textar brake pads and all three competitors achieved even better results than the OEM material. For hot braking, nearly every brake pad except one beat the OEM pad in terms of braking distance. Textar was the supplier with the lowest deviation between the first and tenth braking application, only 0.2m, compared to a competitor with 8.7m which corresponds to two vehicle lengths.

The internationally accepted AMS test was originally developed by automobile magazine, Auto Motor Sport. TMD Friction performed the test within the scope of the benchmark series, to secure and expand the high quality and performance of its products based on the results gained.

Vincenzo Di Caro, Product Engineer of TMD Friction, said: “Today, in a time of high-tech, high-performance cars and increasing traffic, brakes have to generate maximum performance with speeds of up to 250 kilometres per hour. Significant testing cycles are also very important to us in order to check and improve our products. The AMS test shows one of many examples of Textar placing great importance on safety as well as removing prejudice by demonstrating that aftermarket brake pads can be even better than OE products when dealing with original spare parts.”

TMD Friction launched its premium brake brand, Textar, to the UK market aftermarket earlier this year. The full range of products cover 99.9% of the UK car parc and includes brake pads, discs and accessories, including brake fluid, available for next day delivery. The launch of Textar passenger car provides the aftermarket with a superior braking product, complementing the long-established Textar brand dedicated to the OE sector.

TRIPLE T RANGE FOR COMMERCIAL VEHICLES

TRIPLE T RANGE FOR COMMERCIAL VEHICLES

PROMOTION ARTICLE ON BEHALF OF CARLUBE

The largest operating expense for a fleet is fuel costs and any savings made within this sector will have a significant impact for the fleet. As a result, fleet managers are constantly looking for ways to reduce costs and increase fuel economy. Although it may be overlooked, engine oils are a vital part of any operating vehicle, and can also reduce emissions – even a 1% fuel economy saving can help hugely in a large fleet. Although this sounds like a small percentage, when an average annual fuel bill is reviewed, a 1% saving can make thousands of pounds difference by simply changing the engine oil. A potentially large saving for a fleet of vehicles.

Engine oil manufacturers are constantly looking at ways to improve fuel economy in all vehicles. We know that the thinner the oil, the less drag it puts on the engine, and therefore an increase in fuel economy. These oils are now ready to buy off the shelf for passenger vehicles – for instance grades such as 5W-30 instead of 10W-40. However, within heavy duty applications, one of the main concerns with this method is whether lower viscosity oils will protect the engine to the same extent.

Carlube’s Triple T range for commercial vehicles, meets the needs of Truck, Transport and Tractor engines. This range covers over 99% of commercial vehicle engine applications, allowing extended drain intervals of up to 80,000km and reduced engine wear. Triple T products carry formal approvals from leading commercial vehicle manufacturers such as Mack, Renault, Scania & Volvo.

Carlube Triple T 5W-30 UHPD E6/E9 is rigorously tested to provide premium protection against engine wear and fully protect vital components. In the ACEA E6 engine tests, it has been proven to offer over 40% more engine wear protection than the test limit. The formulation is one of Carlube’s most comprehensive offerings for on and off road vehicles in the marketplace.

INDUCTION HEAT VS THE OXY-ACETYLENE METHOD

INDUCTION HEAT VS THE OXY-ACETYLENE METHOD

PROMOTION ARTICLE ON BEHALF OF INDUCTION INNOVATIONS

The use of induction heating in the workshop is on the rise and we asked Induction Innovations Inc., manufacturer of the Mini-Ductor® Venom™ handheld induction heating tool, to compare the advantages of using induction heat vs the traditional approach of using an oxy-acetylene torch for removing problem parts.

There are some key advantages of using induction heat, outlined below. But first, here’s some key questions to ask yourself:

o Have you, or a colleague, ever caused damage with a torch?
o Does removing parts take up a lot of time and would a new solution make your lives easier?
o Do you regularly have to replace parts that you could have kept?
o Do you need to improve safety in the workshop/bodyshop?

Top tips: Why is induction heating technology a viable alternative to Oxy-Acetylene?

Using Oxy-Acetylene is risky
The use of a torch in a confined space vastly increases the consequential fire risk – plastics, wiring, trim etc. around the part to be removed can catch fire, causing potentially costly damage. Replacing damaged wiring can be very expensive.

By contrast, induction heating is a safer, more reliable, flameless heat, created by high frequency magnetic fields, which heat ferrous metals.

Reduced Overheads and Insurance premiums
The cost savings from not using Oxy-Acetylene is striking. On average, insurance premiums are 10-30% less (depending on use and insurance company). Added to the average cost of £150 a year to rent a gas bottle and with the majority of parts having to be replaced, the overheads start to mount up.

Works quickly, helping improve productivity and ultimately profits
Flexible coils, supplied with the Mini-Ductor wrap round the nut and heat it in seconds for easy removal. For example, a 19mm nut is heated red hot in just 15 seconds for easy removal.

As the flameless heat is localised on the part and not the surrounding area, collateral damage to the part is minimised, so parts can often be re-used.

Most importantly, using induction heating as a viable heating alternative to a naked flame means technicians are safer in the workshop.

The market leading Inductor® product range, from US company Induction Innovations, Inc., is a high performance invisible heating solution, ideal for automotive mechanics. The range includes the user-friendly Mini-Ductor handheld unit (available in 240V, 110V and 12V versions) and the Pro-Max™ 2kw trolley or work bench mounted inverter.

These CE marked, easy-to-use tools can cope with a variety of heating needs. To find out more, call + 44 (0) 1953 859138, email info@theinductor.co.uk, visit www.theinductor.co.uk or watch a wide variety of application videos at www.youtube.com/theinductoruk

NEW HELLA HENGST FILTERS FOR WORKSHOPS

NEW HELLA HENGST FILTERS FOR WORKSHOPS

PROMOTION ARTICLE ON BEHALF OF HELLA

Hella Hengst portfolio

HELLA, a leading original equipment (OE) manufacturer and system supplier to the global automotive industry, has recently added antibacterial carbon activated cabin filters to the HELLA Hengst range of OE quality filters.

The 38 new-to-range (NTR) references are available for a variety of vehicles, including Ford Focus C-Max, Mercedes Benz A and C class, and Sprinter, as well as Audi A3, A4 and A5. The range also extends to the majority of VW and SEAT models. These additions, which will be available from early 2018, can be easily identified with the letters ‘LB’ marked on the end of the HELLA Hengst part numbers.

The main difference between the HELLA Hengst carbon activated cabin filter and the new antibacterial version is that while both have excellent odour reduction properties, the latter can also reduce allergy problems caused by contaminants such as bacteria and mould fungi, which enter the passenger compartment through the ventilation system, thus tackling one of the growing issues facing road users by directly addressing the health concerns of vehicle occupants.

Today, modern vehicles have cabin filters located in a variety of places and that are sometimes challenging to fit, making it difficult for installers to service or replace them. To further assist technicians, HELLA Hengst provides easy-to-follow installation instructions for all cabin filter types, including their locations, in every product pack.

As these additions demonstrate, the HELLA Hengst range is consistently growing and with a complete range of 1,500 premium quality filters across 90,000 applications for passenger cars and light commercial vehicles, the company is showing its commitment to deliver the very best in terms of quality and availability to support the independent aftermarket.
