Primary Gear Tolerance issue
Turbo Mini Forums

Gents,

I am trying to set my primary gear up and I am having some issues. I am using 2 sets of feeler gauges so I know there is no rocking going on. I'm trying to set it to around 6 - 8 thou as I am using straight cut.

What I am finding is that one side (level with the prongs of the C clip) is too tight, and the other side is just right. I have tried turning round the C clip round and that makes no difference. I have measured all distances and thicknesses and they all seem the same.

Any ideas? Should I get the tightest gap to be 6 thou or should I try something else?

I've been looking at it for 2hrs today, on and off, on and off etc.

:(

you need to linish a tad! off the back of the bronze thrust washer say using P 180 grit and finish off with 400 wet and dry to get the disired 6 thou

us a flat surface

Cheers, but won't doing that open up the bigger gap on one side even more?

Or should I get the smallest gap to be 6 thou and forget about the biggest? Its the unevenness that is bothering me...

for straight cuts I wouldnt be overly bothered,

although try fiddling with the c clip, they can wear so turnig them round can help.

Cheers, the C clip and backing washer are both brand new...

They are not from minisport are they,

No... but they might from their same supplier? Have you heard of bad ones from Mini Sport Carl

I might try a different 2nd hand C clip if I can find one and if that makes any difference unless anyone else some ideas?

A lot of new parts are pants, basically does the C clip fit in the crank grooves without loads of play?

the grooves in my crank are a tad wide so i couldnt find a c clip that fiitted satisfactorally, so i gave it a squirt of weld and filed it down till it fitted nicely,
