PROMO: CORTECO EXPLODES THE GUIDE BUSHES ‘MYTH’

PROMOTIONAL CONTENT WRITTEN BY CORTECO

 

Clutch input shaft sleeves (guide/ bushes) and seals: essential, but are they really only available through dealerships? Corteco explodes the myth.

The first call for any replacement part is the local motor factor, but when it comes to a part such as a clutch input shaft sleeve (guide/ bush) and seal, most UK garages turn to dealerships.

Essential in clutch changes for many German, Italian and French-built cars, dealerships hold a virtual monopoly on aftermarket sales throughout the UK. But the fact is, they are not an OE supply only item.

Garages only think they are.

 

New direction

Split-open view of a guide bush

Until quite recently, for example, that’s precisely what they thought up at Almark Garage in Wirksworth, Derbyshire:

“We always sourced them through the dealers. It just seemed like the place to get them because it was associated more with the OE gearbox than the clutch,” says proprietor Mark Swift.

“Our problem was that once you’ve got the vehicle up on the ramp and the gearbox off, you couldn’t hang around all day. Sometimes service from the dealers leaves a lot to be desired, so it meant that we didn’t always replace them, even though we know they can be a source of problems with the clutch.”

Almark is fitting more, now, because the availability has improved.

“It was only when the motor factor came along about three months ago and pointed out that they now had them in stock that we switched over. They are not expensive to buy, but even so, they are half the dealership price. I have to say that the service they provide means we are now fitting more than we ever did,” he adds.

 

Guide/ bush function

When not in operation, the clutch release bearing withdraws and comes to rest on the shaft sleeve. The shaft sleeve can become pitted through wear and tear. A worn release bearing can catch on it, leading to misalignment problems that can cause the clutch to slip.

This accelerates clutch wear.

Inside the shaft sleeve is a rubber seal. This is designed to protect the clutch from ingress by gearbox oil. If the seal fails there are problems ahead. Seal failure is often related to debris generated by clutch wear.

 

Contaminants

Clutch ‘dust’ accumulates in the gearbox. If the dust accumulates on the shaft and on the sealing lip, the seal can be compromised. It can damage the seal and reduce operational life. A worn or damaged seal allows the oil to leak into the clutch housing. If this contaminates the friction plate, premature failure of the clutch is inevitable.

This leads to excessive slippage. Any excessive slip between the clutch and flywheel causes overheating. Soaring clutch temperatures increase the potential for failure.

Installation errors

After removing the clutch, the clutch input shaft sleeve (guide/bush) and seal is sometimes ignored or not considered for replacement. Three alternative views are:

  1. a) It is part of the gearbox, rather than the clutch
  2. b) It looks ok, so let’s save the customer money
  3. b) They are difficult to replace so are best left alone

Each of these constitutes an error of judgement that can expose the garage to an expensive rectification procedure and damage its reputation.

Best practice

Corteco, one of the world’s largest manufacturer’s of clutch input shaft sleeves (guide/ bush) and seals, says that although these components are highly reliable performers, they must be replaced when changing the clutch.

It adds that because so many garages have always sourced their replacement from dealerships, many motor factors are unaware of the demand.

Given that labour is the major cost of the clutch change and that the clutch input shaft sleeve (guide/bush) and seal is not an expensive part, garages would be inclined to change more of them if the parts were available. A campaign to raise awareness about aftermarket availability is under way.

PROMO: HELLA HENGST – THE FILTRATION EXPERTS

PROMOTIONAL ARTICLE FROM HELLA-HENGST

 

Workshops have a responsibility to their customers, not just when it comes to the standard of the work they undertake and the quality of replacement components they fit, but also in terms of service and advice they offer. In addition to these customer-facing benefits, this principal will also help workshops both in their reputation and the bottom line.

In terms of vehicle performance, engine emissions and to minimise fuel costs, ensuring the regular replacement of the air, fuel and oil filters with an original equipment (OE) quality substitute, such as a HELLA Hengst filter, is of the utmost importance and any workshop that would even consider straying from either the vehicle manufacturers (VM) specified service schedule or turn to a low quality alternative replacement, would be considered as to have made a reckless decision.

Where workshops can fall down however, is with the replacement – or lack of replacement – of the cabin filter, which effects the health and well-being of the vehicle’s occupants, an equally

Hella Hengst portfolio

important part of a customer-focussed outlook.

Air quality is always in the headlines and providing a healthy environment for their customers is one of the ways that workshops can distinguish themselves from their competitors. Many studies have shown that the air quality inside a vehicle has a significant influence on safety; when it is thick with pollutants for example, the driver’s concentration can suffer, resulting in a higher risk of an accident.

Incredibly, up to 540,000 litres of air can enter the cabin for every hour of driving and research has shown that this air is approximately five times more contaminated by exhaust gases, pollutants and allergens than air at the roadside.

Workshops therefore, have a large part to play when it comes to the air quality within their customers’ vehicles. By specifying a HELLA Hengst Blue.care® cabin filter, they can optimise the air quality for the direct benefit of their customers in terms of a reduction in pollutants within the vehicle, which aids the driver’s concentration, makes them feel less tired and subsequently reduces the risk of accidents due to driver fatigue.

A standard cabin filter is certainly a good first step as, in addition to its protective role over the air conditioning system, it will remove pollen and fine dust, whereas a carbon activated version goes one further by filtering out bad-smelling odours and hazardous gases such as ozone, smog and exhaust gases. However, the HELLA Hengst Blue.care® filter also neutralises allergens and bacteria, making the environment particularly suitable for the family car.

Its first line of defence comes through an electrostatic medium that keeps out coarse particles, which is supported by a filter fleece that increases its dust retention capacity. An active carbon layer separates out vapours, odours and harmful gases, while so called ‘meltblown’ medium filters out fine dust including micro-particles with diameters smaller than 2.5 mm. Finally, the biofunctional layer contains nanosilver, which has an anti-microbial effect and jointly provides the five level protection from pollen, dust, mould/spores, odours and bacteria that makes the Blue.care® the filter of choice for the discerning workshop.

Due to the sheer quantity of air cabin filters have to cope with, HELLA Hengst recommend that they are replaced annually or every 10,000 miles, whichever comes first. However, vehicles that spend most of their time being driven in busy traffic – like the typical school run – should have them changed twice a year, irrespective of their annual mileage.

LUBRICATION THAT CAN DAMAGE OIL SEALS

LUBRICATION THAT CAN DAMAGE OIL SEALS

PROMOTIONAL STORY ON BEHALF OF CORTECO

Today’s cars are becoming increasingly powerful but are still retaining the convenient size which fits with the chaotic world we live in. With cars becoming more demanding, the engines have to do more while trying to meet efficiency targets, this is helped by the engine oil that we put in to keep the car ticking over. However, although this oil is beneficial for many parts within the engine it also causes a lot of harm to components such as oil seals.

Oil additives are chemical components that improve the lubricating performance of the base oil. These additives are vital for the proper lubrication and prolonged use of engine oil in modern combustion engines. Without many of these the oil would become contaminated, breakdown, leak out or not properly protect the engine parts at all operating temperatures. Some of the most important additives include those used for viscosity and lubricity, contaminant control, for the control of chemical breakdown and for seal conditioning. The viscosity of oil also changes with temperature, becoming more viscous when cold and less viscous when hot. So the viscosity of the oil can be affected both by the weather and how hot your engine is.

Although the additives in the oil are extremely beneficial for most engine components, the additives being used today have an adverse effect on oil seals, often causing them to wear or leak causing early repairs being done to fix the problem. One way a seal can fail from oil additives is due to chemical compatibility, this is an issue that arises when changes are made to the formula of lubricants. Sometimes even though the base fluid remains the same an additive causes the seal to fail. However, the effect is not always predictable as the seal may wear out faster than expected or simply not perform as it should.

Alternatively the seal material can break down when it encounters a corrosive fluid. This will occur when the improper seal material is chosen for an application. The use of non-compatible materials can lead to chemical attack by oil additives, hydrolysis, and/or oxidation of seal elements. This will result in the loss of the seal lip interface, softening of the seal durometer, swelling, and/or shrinkage of the seal. Discolouration of the seal is an indicator of chemical erosion.

To avoid the seal from wearing early or not performing as expected then certain things need to be looked at. The fluid pressure range needs to be checked, this includes not just the operating range of the fluid system pressure, but also the severity and frequency of the system pressure peaks.

Another crucial factor is the temperature range as this will be effected by the additives within engine oil and can also be effected by the engine temperature and even the weather. The resting and operating temperature range of the fluid and the cylinder assembly are important with seal selection.

The fluid type due to the fluid media and viscosity are important for seal efficiency and effectiveness. Getting this right will ensure the long life of an oil seal as well as reduce the need for early repairs.

The size of the seal will determine the size of the cylinder. This includes the rod and bore dimension, seal groove dimensions, gaps, cylinders overall length, surface finish specifications and the stroke length. How the cylinder is used will impact how long it can last under certain operating conditions. This includes cylinder installation, environmental factors, and exposure to harsh conditions.

With oil additives being added to engine oil it is becoming ever more crucial to ensure the right seal is chosen not just for the application but for operating conditions and to work well alongside the additives.

Corteco offers a range of more than 7,000 gaskets and over 6,500 different shaft seals Simmering® and valve stem seals in OEM quality for a wide range of vehicle applications to ensure you can get the right seal for the job.

PROMO: 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.
