Nick, I have a b6100d, after reading the operators manuel, it said there is a adjustment under the seat. It is for the 3ph, to control the drop speed in case it is a heavy implement it wont slam it down. I dont know if it also controls the loader end. It looks like a vertical bolt with a jam nut (17mm?) As far as the clutch replacement, dont skimp on all the parts like I did cause I am fixing to brake mind down for the second time.Also you need all metric wrenches and sockets,floor jack and jack stands.Its not that bad of a job. Good luck, rptp44.
