I was wondering if the folks on this forum could help me? Decided that I should check and make sure that the flywheel on my 70 diesel was not working loose. Not sure if I am using the best procedure to check the flywheel fit, but in my looking I noticed some crankshaft end play. I also noticed that the crankshaft seal is seeping oil from the left side behind the flywheel. I pushed the clutch handle forward in the lock up position and then moved the handle fore and aft to detect the end play. I do not have a dial indicator but if I had to guess, I have about .015 end play using this method. I have a John Deere Dealer Service Manual. It calls for .005-.010. If indeed I actually have .015, should I correct the end play and oil leak?
The service manual confuses me in a couple of ways as well. 1st, it has me check the end play 3 separate times.
It has me add or deduct shims behind the trust cover to reach the .005-.010 end play off the left crankshaft end.
Then it tells me to make a pipe spacer from 2-3/4 pipe by 3-1/4 long and install it over the crankshaft and secure the flywheel retaining nut, without the flywheel installed of course. After this, it tells me to check end play again and adjust with the correct shims again. I assume that the pipe spacer is acting like the flywheel??? This also leads me to believe that the install of the pipe spacer (or the install of the actual flywheel.) will change the end play. Why is this? The manual also says that when I install the flywheel for real, to block the crankshaft all the way to the left in order to prevent dislocating the thrust plate. How in the world do I block the crankshaft to the left? Do I have to remove the pony engine to gain access to the inner crankshaft and figure out how to wedge block it to the left? That could be a real pain!
After the flywheel is torqued in place it tells me to check end play once again.
Any advise or comments to these questions would be appreciated. Thank You.
