grease!! - daft question alert...

[ermie571]

Right....going to have a bash at replacing the bushes on the linkage. Drowned liberally in plusgas today.
Now...Mr bentley says to grease everything.....so, what grease? Seems to be black CV grease and white grease.

so...is CV grease just for CV's....and do I need the white grease?

And do you put a smear around the shaft, or pack it in the bush.

Also, looking at the pack, i have 2 different bushes....one a clear bush, one a beige one with grooves. Which one is the front, and which one is the rear? Hopefully it will become clear when we take it to bits, but would like to know. (bentley seems to show the same part front and rear)

What is the purpose of the groves...

thanks for any help, tricks, does and don'ts.

E D I T - have just read the refurbish your linkage articles! fantastic.....but have decided to send to garage as cant do it roadside...

A cartridge of white grease or silicone grease should do the trick, Molybdenum Disulphide grease (moly) is usually only used on 'high speed' applications such as CV joints same with EP2 grease which is usually used for wheel bearings.

To be honest though any grease will do on a reletively static thing like a gearshift linkage.

Thanks Ian - explanations are always useful

Pack the bellows and load the bushes as much as you can .... I do it every year before winter, same time as I waxoyle the underside.

waxoyle t'wasnt so many years back in your area youd have popped down t'mill and scraped up some goosefat oft shafts mixed with sweat from the weavers, that'd keep't rust at bay

Giggidy giggidy!


(Sorry had to do it)


I use moly grease for everything (car related) to be honest. Does the trick.

The most common and generally useful grease...is 'Multipurpose LM' high melting point grease....good for most things including wheel bearings, chassis, cables, linkages, pivets...perfect for the gear linkage.

If your'e only going to buy one tub of grease it makes sense to buy the most common type that can be used on most things.......

However, there are many other 'application specific' grease types for things like:
CV joints (Lithium/Molybdenum grease)
Brakes (specialised pad grease...Mintex CeraTec or similar) not copperslip.
Electronic components to chassis (Thermal Heat Transfer grease)
Rubber components (bushes/mounts) red rubber grease.
etc

Like Ian says silicone or a poly grease should be used as it is waterproof (VW used poly grease). Normal greases emulsify when exposed to water spray under the van.

[California Dreamin]

Can't honestly remember being told to use silicon / poly grease, although I do understand what you are saying about LM grease emulsifying, this area isn't really subjected to direct spray....
To be honest, just about any type of grease would do, it's not that critical unlike many other applications. However, as this was a specific question a waterproof grease might be better.

It is in the workshop manual.

[California Dreamin]

Ideed it is...but do you think we had time to sit around reading manuals for a simple gear linkage repair? we would have been laughed at by the workshop foreman/service manager for such a thing.
Just like all those 'torque settings' a technician on bonus isn't going to spend time messing about doing that?
After a dozen or so more years in the trade, if you can't judge how tight something should be by feel then you shouldn't be doing the job.
Whilst I'm not questioning the importance of workshop manuals, Volkswagen and any other manufacturer for that matter, really wouldn't expect a Master Tech needed to refer to such material for relatively straight forward repairs. Point of 'correctness' ie: the right type of grease, in this instance is splitting hairs, as long as it was assembled and lubricated with something suitable.

nice bit of hair splitting but agree ,general purpose grease is good enough for this sort of linkage, lest face it even goose fat would be better than nowt,
special greases do have their place as in waterpumps,cv's,O2 etc
