Correct Grease for Driveshaft Splines?

[KOY 23]

I am overhauling my driveshafts and was going to grease the splines with grease made for CV joints as they lead a pretty hard life. More stress than a Stag would give them, I thought.

However Stustag said the graphite grease was the one to use but I cannot get any from the factors I use.

Any suggestions please?

John.

I used copper grease on mine after reading a previous thread, although I can't find it now I have saved the document from another website detailing how to replace trailing arm bushes on a Triumph 2000.

Anyway, here's a snippet and if anyone wants the whole article send me a PM

16) Now to sort out that rear end twitch! Clean the splined end of the driveshaft with thinners/white spirit/paraffin. Then liberally coat with my favourite "Copperslip". Put more on than you need as the excess will be forced out when you re-fit it. Don't put any on the end as this could cause hydraulic lock on the spline. Cut the string and replace the brake assembly on the arm. Mind the brake hose. Reconnect all the clips including the 9/16th nut on-top of the arm. Now thread the hub and shaft back through the arm. To line the spline up you will see that there is one "key" spline that is bigger than all the rest, this will line up with a similar one on the other end of the shaft. Slide into position, avoiding the brake assembly and springs until the hub is home tight on the arm. (Note, the wheel cylinder should be at the bottom)

Many thanks Kevin.

Copperslip it is then.

I guess Stustag is too busy selling, to reply. He will never make 1000 posts by this Easter at this rate..

Im not so sure about the suitabiaty of copper slip i thought is main attribute was to stop bolts seizing not actally working for its living .

wait for stustag to return to his cottage he will put the record straight

Just to be clear I'm not saying that copper grease is the correct thing to use nor that it is better than graphite grease, but it is available! and better than dry rusty splines.

When I did my shafts there were traces of graphite grease there already, but only traces.:?

The correct grease recommended by Triumph in the 2000/2500 workshop manual is Rocol Molytone 320 or Duckhams Q5648 but not even mentioned in the assembly of Stag halfshafts.

I use Graphite grease as it was recommended by Chris Witor for my 2000 MK2 and if you read this link it is for sliding joints and stop corrosion and seizure!

Copper slip is for use as and anti squeal agent on the back of brake pads and as an anti seizure agent on brake pins etc, I don't think it has the wright protection qualities for this spline application.

Sorry for the late reply on this but I am under a lot of pressure at work!

I couldn't find a supply of graphite grease so I have used molybdenum grease on mine for years on my PI with no problems at all. For example I have had no spline lock with this grease.

Stuart of SOC spares, suggests CV joint grease as it contains a percentage of graphite.
