Trying to adjust a new clutch in the 3 cylinder diesel 3000 with dual clutch. Following the IT manual had no problem setting the "G" dimension for the PTO clutch. Setting the release fingers to the 2.110" dimension from the PTO hub face to the release finger adjusting bolts is not going well. I had to move the jam nuts from the back to the face of the fingers because I had no thread protruding from the back for them to thread on to. My concern is if I have enough thread engagement on the adjusting bolts. It is a new clutch assembly purchased from this site. Also the clutch disc that came out of the tractor had the long side of the splined hub towards the flywheel as is stamped on the face of the hub. The new disc is not stamped and the manual says to assemble with the long hub toward pressure plate except on the 4000 model,sort of confusing in that this same clutch assembly is listed for the 4000 as well as 3000. I am using a verneer caliper to measure the release finger dimension, anyone know a better way and how critical is this dimension? Any 1deas?
