The lever is definitely a loose fit on the splines. I have put this down to wear & tear? Apart from adding fibre washers to try and keep the lever away from the alternator housing, the next thing I was thinking of trying to fit a thin piece of metal between the lever and the shaft, to get clamped as the pinch bolt is tightened.
I believe I can also buy a new shift lever - this should have undamaged splines so it should tighten up. Heiden tuning has what looks like original for 14.50 Euros and Yambits has an aftermarket one for £10. Think I might need to invest unless bodging works.
Hi Raymond,
my shift lever-tightening bodge was to drill a 1/8" hole into the shifter/shaft spline interface and drive a roll-pin into the hole.
Use a 1" long roll-pin so you can remove it with a vise-grip should you need to remove the side case casting.
