Got a 77 450 case that I've had for about six years.When I bought it there was a rattle that sounded like the converter bolts were loose,so we pulled the converter out there are no bolts.It drives the converter with a fibre tooth ring gear.It was worn and loose so I bought a new one,put it back together and it still rattled.I called a case dozer gurus and he said that the ones with that type of drive all rattled.Im getting ready to sell it but don't want to if there is something wrong.Any one else ever heard of this?It does it at low idle,sounds quiet under load.

Is it a rattle that is heard at different spots around the machine? How loud of rattle is it?
My early 70s 450 has a rattle toward the front of the machine at idle. Always has.
As long as your oil pressures are good and everything is tight then I wouldn't worry about it. These things are dozers, not Cadillacs.

I know where its coming from,its the fibre/bakelite drive that goes into the flywheel and over the front of the converter it transfers power from the flywheel to the converter.It has a few thousands of play.I just don't know if this is common on the older 450s Ive had it apart and put in a new one,and it is only slightly better.
