When I got my K75RT ex police bike, one of my first jobs was to lubricate the rear drive splines and gearbox output splines. I used Optimol T white paste, for driveshaft, gearbox and bevel drive splines as recommended at the time by Motobins in the UK. I had a look at the Invoice, to be sure that I remembered this correctly and here is the line from the Invoice. Part No.95815 OPTIMOL T WHITE PASTE DRIVESHAFT/G BOX/BEVEL ALL K 100GRAM TUBE.
My bike had only 29.000 kilometers on the clock when I got it, unusually low for a Police bike, but still showing many signs of neglectance. I suspect that the splines have never being lubricated since new, until I did it. I seem to remember that I found the drive splines to be in good condition but the splines at the rear end of the shaft showed some wear. At the time, I decided to use it, at least until the next lubrication.
Now I'm in there again after about seven thousand miles. I took out the drive and the driveshaft this weekend and after inspecting it I have my doubts about using OPTIMOL T WHITE PASTE on the drive splines and I am afraid I will have to fork out 250 Pounds for a new driveshaft! I think (and hope) the drive splines are good, but the rear splines of the drive shaft show what I think is rather heavy wear and there is a substantial play evident when I slide the shaft upon the splines and wiggle it.
Please take a look at the pictures. All comments and opinions are very much appreciated to help me to decide what to do.
