wiggy Posted August 13, 2014 Report Share Posted August 13, 2014 Hi All I am about to put my gearbox back in after clutch replacement. Should I apply grease to the splined input shaft and shaft cover/release bearing sleeve. I have also replaced the clutch cross shaft and bearings (2 each side) how should these be lubricated now that the new shaft is without grease nipples?

MRG1965 Posted August 14, 2014 Report Share Posted August 14, 2014 HI, be careful, any grease like compound can become loaded with the dust from the clutch driven plate and slowly become very thick and eventually impede the free movement of the driven plate on the input shaft splines. Same reason never to lubricate the end of the thrown in type started motor gear as this also eventually sticks on the corse screw thread it runs in and just leaves you with that spinning noise, but no engagement in the flywheel teeth. I have seen in the past a dry spray lubricant almost like a paint that dries, so does not catch dust, but lubricates this type of requirement, don't know what it is made from or remember what it is called, so not really a lot of help...

Lebro Posted August 14, 2014 Report Share Posted August 14, 2014 I thought the same when I read the above - I never apply any lubricant to the splines - only the spigot. The dry lubricant you speak about may be "DrySlide" it a moly based substance in a solvent - squirt on, & the solven evaporated leaving a thin coating of moly. Used on guns sometimes. Bob.

peejay4A Posted August 14, 2014 Report Share Posted August 14, 2014 I'm with Neil. Copaslip on the gearbox front cover and the splines. Just a smear, that's all. Quote Link to post Share on other sites
MRG1965 Posted August 14, 2014 Report Share Posted August 14, 2014 Thanks Bob yes, that was the sort of thing I was thinking of. I recall it leaves a grey coating. Mark Quote Link to post Share on other sites
peejay4A Posted August 14, 2014 Report Share Posted August 14, 2014 Copaslip is an anti-seize compound, not strictly a lubricant although it does provide some slide. It sticks in a thin layer, stays there and is tolerant of heat - hence its use it on the back of brake pads. Never had a problem with dust pickup, even on the brakes which are much more exposed to the elements than the clutch. Also it doesn't get flung off the splines onto the clutch surface. As always, the choice is yours. Quote Link to post Share on other sites
