Thread: New Spline 109 Prop Shaft

Front Prop Shaft
I have bought a new splined shaft end and yolk which were both severely worn. I machined out the splined end welded into the shaft and tapped the new stub into the pipe.
I machined a center hole into the fixed yolk end and set up the shaft in the lathe between two centers i.e one center in the 3 jaw chuck and one into the end of the new splined section already center drilled.
When I run the shaft it has a bit of a wobble - i will try and tap it until it runs true.
How do I make sure when I weld it that it stays dead straight other than stitch welding on opposite sides.
Anyone done this operation before?
Can I weld it such that the yolks are 90 degrees from each other as shown on page 47-1 of the manual - I forgot to mark the old one before I stripped out the worn bits.


Thanks

I also made a mistake by first buying only the yolk end as the spares guy said that the splined part does normally not wear out. Cost me R250 which was not too bad.
When I tested the yolk and found my splines were indeed worn a got a shock that the splined section was double in price (R560).
The new complete shaft would have cost me R1500 new.
