Tailshaft splines D2

[davros]

Hi all,

Just wondering - are tailshaft splines a matched pair or can you make "one out of two" by selcting two "least worn" halves? (then yes getting them balanced :mad:). Mine has the plastic coating worn on the male splines from when the previous owner (or lack of service quality by Land-Rover) let it seize, but the female side seems ok. Is the female side supposed to have a coating or is it bare steel?

PS I have been wondering how many exploded Hookes Joints have been the result of lack of spline lubrication? It seemed to me the alan keyed grub screw had never been removed to put in a grease nipple and grease the splines, they were that seized.

I'm not sure what the answer there is, and have also wondered if the plastic coat is used to ensure an exact fit also.

The hookes joint is the uni joint, there are no splines in it, but I do agree that the double cardin joints (double hookes) joints fail as a result of no lubrication.

At least on D1, you can mix and match - although the splines are spaced so the uni is in the proper position ( ie don't force it). The main shaft is bare, but the short end is built so the plastic coating ( Rilsan - google it for an explanation) acts like a frictionless sleeve. Whilst there are places that can do that sort of coating, finding a decent 2nd hand version is far easier. You shouldn't need to re-balance the shaft as the short end can only fit one way, which should retain the original balance.
