Just rebuilt my r150f with new bearings only. Syncros and gears were okay. The counter shaft was done, it was all pitted on the surface for the rear bearing. Picked up a used one from eBay. Got everything back together, but had a bad whine in 5th gear and a lot of dark grey sludge when I tried to do a fluid change. I opened everything back up to see what I did wrong but besides the grey sludge, everything seems fine.
Questions:
1) how much play should be in the countershaft? When I have the tranny apart (just center plate remaining) the counter shaft can move in and out maybe 2 or 3 mm.
2) what is the greg sludge? Why would I have so much of it?
3) what would cause a whine in 5th gear?
Thanks!
