I am about to do rear engine seal and all it entails as in do everything else while in there, on the 84 K100RT.

Not sure what I will find when I go at it but since I know there is a risk on the splines I have a question.

The spline end that can be welded on to the drive shaft as far as I know is for a 20 spline drive shaft, no 16 spline option?

However is it possible/feasible to weld a 20 spline end to a 16 spline drive shaft?

I know it means a change of final drive to do this but my LT is sitting there with a known good 20 spline 32/11 final drive.

My first choice is to take the 31/11 final drive off the 84RS but unfortunately this is not a known good one so would need refurbing first.

G'day Olaf, yes it is possible to weld a 20 spline onto what was originally a 16 spline shaft. The splines are identical except for the number of splines, Cheers Tom

Many thanks for that one. I had a thought it was possible but its a good option.
