I have finally got a project straight 450 crawler loader running. But I cannot get the engine clutch adjusted according to instructions in the manual.
I have both the operators manual and the service manual. The procedure for clutch adjustment is the same in both. My main problem appears to be that the throw out bearing does not contact the pressure plate release fingers, even when I remove all the pedal free play. If I adjust to the desired pedal free play (3 3/4") the H-L-R clutch disengages but not the main flywheel clutch.
I can just barely view one of the clutch pressure plate release fingers through the bell housing access hole and the throw out bearing carrier is moving as expected but not far enough to contact the finger. I cannot figure out how this would be possible unless a part of the throw out bearing is missing or the flywheel is thinner than it should be.
Background. I purchased this machine as a project, having been told the engine was a replacement. Its a 4239 engine which I rebuilt. It fits fine and runs well. I adjusted the clutch release fingers before installation according to spec. I checked the throwout bearing while the engine was out. It spins nicely and looked to me like it should. Pic shows the bearing while the engine was out.
Could there be a part missing on the contact face of the bearing? Or could the flywheel on the 4239 engine be different than the original, causing the pressure plate fingers to be in a different plane than designed? Or some other cause that I have not thought of?
I really dont want to remove the engine to check this out but will do it if it is the only solution. Any ideas?

Another 450 HLR clutch adjustment question
Pulled the engine back off and adjusted
The clutch fingers a little
Put the engine back on and with the
Clutch adjustment bolt ran all the way
Down the throw out bearing just touches the fingers when pedal
Is all the way down and the free travel is way too much
If I put a three quarter inch spacer under
The bolt I can achieve the right amount of
Free travel
I am not sure what the clutch pedal should feel like
When disengaged but it is pretty hard push
And never breaks over for lack of better words
Like most other clutch pedals I have used
I am not trying to hijack your thread I am having
The same problem as you maybe we can figure out
Is missing here
