Yes, the job is rather involved. You have to jury-rig a measurement device to set the height of the fingers on the pressure plate - I do mine with the flywheel off and sitting on a flat surface and mounting & torqueing the pressure plate down to do the setting, then disassemble it to reinstall in the tractor. Be sure to tell the shop to use BETTER QUALITY bolts that won't stretch and some Loctite. I believe the bolts stretched just slightly from the loader use and that little bit of stretch was all it took to loosen the bolts initially and they just got worse as time went on. Since doing that job years ago, I've since had to split the tractor several times for a broken bolt in the pressure plate - one of the ones you adjust to get that finger height setting. The head that's recessed in the face of the pressure plate snaps off. You will lose ability to disengage the clutch when this happens - you have to start it in gear to move and pop it into neutral to stop when it happens. That's how I learned how to do a split & clutch in about 6 or 7 hours.
