Might remember before Christmas I was haveing problems getting the right idler gear clearance. Only had 0.001" clearance with the thinest shims. So I had one shim ground down by 0.003" expecting 0.004" clearance. Well there is now ZERO clearance - gear spins by hand OK so it's not binding (before it felt stiff). The idler gear has one long and one short shaft. I have a Cooper box with an idler gear in it but it is short/short shaft. Anyway I tried that in place and I have 0.022" clearance Don't know if it's the short shaft rocking in the bearing or there is really that much but I put the original back and there is no clearance again even when the nuts are hand tight without even taking them to 18lbs so I'm stumped - What's the problem - crooked idler shaft?

Might not be the problem but i recall the gasket normally included with the set is the wrong thickness (too thin) - I always had to buy one separately

The one I use in the mable maroon/creamy coloured one. In fact I have never adjusted an idler gear clearance (if the original gear/washers were used in gear casing before) using this type of gasket - NB I haven't bought a new one for about 10 years, still had a couple in my shed until recent clear out.

Measure the gasket, the red/pink ones used to be .035" or so but they are thinner now.
Find a thicker gasket than what you have, go pester Matt Read....
