Re-coupling large tractor clutch
This is a valuable lesson I learned about recoupling the two halves of a large farm tractor after doing something like a clutch job.
Most later model tractors with live PTO have two clutch discs or a single drive clutch and a splined pressure plate that drives the PTO.
There needs to be an inspection plate above or below the clutch housing that will allow access to the back side of the pressure plate.
Instead of bolting the clutch pressure plate up to the flywheel, aligning the one or two splines on the clutch discs, bolt the clutch up to the
flywheel and do not concern yourself with aligning the pressure plate splines or the clutch disc splines pilot bearing etc. When it is securely
bolted to the fly wheel fabricate three shims that will fit tightly between the pressure plate and the levers where they are attached to the bolt
that releases the fingers on the pressure plate so that when you remove the pressure plate from the flywheel with the discs the fingers remain
pulled down like it was still bolted down onto the flywheel.
Now place the pressure plate and the clutches onto the input shaft/s of the transmission and proceed to bring the two halves of the tractor
together. @ Clutch housing and engine block. All you will have to worry about is getting the two halves even top and bottom and sides so that the
pilot shaft enters the pilot bearing/bushing.
Install a couple of bolts to draw it tightly together and then to through the inspection plate that allows you to get to the back of the pressure
plate. Install the pressure plate bolts just snugly to the flywheel of the first of the three places that bolt the pressure plate to the flywheel
then turn the flywheel to the next place where the pressure plate bolts can be started. Do this to all three places then turn the flywheel to the
first place you sneged the bolts and finish tightening them to the flywheel. Do all three places. The shims you made to hold the fingers down will
fall out as you tighten all three places.
Lots easier that trying to wiggle and shake and twist and turn a big tractor trying to make those two splines and the pilot shaft to align.
I did a big IH tractor by myself in about a half hour by pulling the rear section on a rolling floor jack to the front engine section with a come-
along.
May have to remove the steering sector on a Ford tractor to do this way to have access to the pressure plate bolts.
You are welcome.
