I split the crankcase on the Brute today (going in for a spun bearing) and let me assure you guys that when we think we are flushing all that crap out after we drownd them boy are we wrong.There was a scary amount of sludge still in the bottom. Theres a screen at the bottom the catches the big stuff and mine had plenty. The crank case vent leads to a cavity that had a 1/6 " layer of oily mud caked on the bottom and sides. I tried takeing some pics with my cheap digital camera but it wouldn't focus clear enough.
The damage:
One crank with a severe wear pattern on the down stroke side of the lobe.
One rod damaged by spun bushing.
All bushing damaged.
Crankbushing in left half of case damaged.
Oilpump damaged from metal and crap in oil.
Cylinders are fine, messure within spec, just goona run a hone thru them. Gonna need rings though.
Final tally on parts is around $800 (from RonAyers)
