Hello all--need info on this clutch set-up, believe it is the borg&beck 2-stage. so far, I have adjusted the 3 small set screws on pressure plate--[turn cw to stop, back out 2 rds,] info found in archives]. the main clutch works great,& can feel 2nd stage, PTO will not release. I blocked the P plate fingers, & found I could remove all the bolts thru access hole-this let the unit slip back on my dowel bolts, & I could put pto in gear--shaft would turn-, THE DISC is not stuck to flywheel, etc so I am trying to wrap my head around how the apply plate works, & is it stuck, broken--chance to free it up without a split.? I have washed it down w/brake cleaner, as best you can thru ports] PS--already tried making it release with mower attached, may try again after this work. Thanks for any input---
