I just done a torque limiter in an 8050 and the last inch didn't slip right in smoothly like it did on the 7020 I did years ago. I got it aligned.. removed dowels, and had to slowly sucked it together. it was MAYBE 1/8 to 1/4 of an inch off from side to side, 1/8 inch top to bottom. It took little effort turning the bolts (front frame to 'bell' housing) Id tighten one 3-4 turns and move to the next, side to side.. ..etc. .... it sucked in evenly as I turned the bolts.. using maybe 35-45 foot pounds to turn the 'drawing' bolt. When I got to the other bolts they were turn able by hand. I used a different bolt each time as a 'Drawing' Bolt. What I'm concerned with is, could it be because the pilot bushing was dragging or got damaged. (New bushing) Once I got the splines lined up on the clutch it went right together, till that last inch to 1 & 1/2. The pilot shaft bushing and shaft / splines had light grease on them.. hydro locking? Or am I just worrying for nothing.
And does anyone have a page or two of wiring schematics and a break in procedure for the clutch.. Seems like You purposely slipped them for 15-20 seconds 3 or 4 times..its been 9-10 years for me.. I had to forget many things to remember new >

turn the crankshaft/flywheel while mating. Very dangerous drawing together with a bolt... Let the unit warm up, put in high gear, rev up 2000 plus rpms start and brake torque till it slips. let the unit cool at 1000 rpms for a few minutes and repeat. Wait longer intervals for cooling after each slippage. Continue til it kills the engine - or brings it down to 600 rpms at which point pump volume may let wet clutch slip. Do not let the clutch slip for over the few seconds it takes to clutch the tractor.
