Close but not quite

Putting the 65 diesel back together after replacing clutches and seals. I believe I have engaged both of the clutch discs as I can put it in high gear and turn the rear tires by prying on the ring gear. PTO shaft turns in engine PTO mode when prying on the ring gear. My gap between the engine block and clutch housing is an even inch top, bottom, left and right yet I cannot get the two halves any closer. My guess is that the input shaft is not engaging the pilot bearing but with the gap all even assumed it was in line. Anybody got any suggestions ?
 
Try Engaging the pto and turning it with a pipe wrench while trying to work it together. I've had success with this method.
 
Hi
Did you fit a new pilot bearing in the flywheel, if so did you put it on the shaft to check fit first. Wouldn"t be the first time i was given a wrong new bearing with a smaller internal bore/ Have had one too big as well in the past but found them both before assembly.!

Other thing is did you use an alignment tool to center both discs to the pilot bearing in the flywheel.if not that might be slightly out of whack.
You could have enough play in the shafts they both went through. but are a few mm out for the input to go in the bearing.
have done many tractor clutches some go easily others are a P.I.T.A. Have you slacked back the clutch rod adjustment also. could be the release bearing is hitting the clutch toggles stopping it going up. if release bearing is adjusted right forward, or clutch levers are to far back are they set up to factory specs for distance.
I Have had some go back together that needed a gentle even pull with bolts to close them up. But using this method you need lots of experience doing clutches to gauge whats enough pressure or to much without bending discs.on a case tractor a guy can get a disc the wrong way round and that won't let it go the last inch to, don't know if that can happen on a massey or not.

As with all internet diagnoses if I was there I"d have a better idea on if you got a problem or not and your just slightly scared of messing something up.
There are just so many variables on every clutch job

I did not change the pilot bearing or the throw out bearing. Both were in as-new condition. Even the discs had little wear, they were oil-soaked. I set the release fingers at 2.065" from the PTO disc (not hub). I don't know how that compares to the OEM gauge, but my understanding is that the imperative is that they are even more than the set height. Am I correct? As it went together I had the engine PTO engaged and spun the PTO shaft as we pushed it forward. Can't say I felt it "snap" into place but there was a point where the disc was engaged. When we got to the one inch point it seemed as though the rear portion of the tractor was pivoting around a hard point which led me to think it was the alignment of the transmission shaft and pilot bearing. We were pushing on the left tire then right and slightly manipulating the height with the jack just to see if something would pop in to place.
 
I did not replace the pilot bearing or the throw out bearing;both were in like new condition. There was little wear on the clutch discs, they were replaced because they were oil soaked.
My pilot tool did not arrive in the order with the new discs so I used a 10 spline from a Ford pickup repair and added some electricians tape to build the pilot to the correct diameter. I centered the PTO disc as best I could on the pressure plate. Perhaps there is a slight misalignment that deflects the input shaft? I'll roll it back apart and check the alignment whenever UPS decides to grace me with the tool.
