300B brake problems

I'm fixing up my uncle's 300B and he was having problems with the left brake locking up and would not disengage until you backed up. I disassmbled it and all looked OK. New brake disc and no rust. I did find about 3/16" of end play on the splined shaft the disc mount onto. I think there should be not end play on the shaft as I think it keeps the ring gear in positoin. Could the loose shaft cause the brakes to lock up?

I had the same problem with a 300B and I found on this forum that the small springs that hold the steel brake plates together get weak and will allow the steel ball bearings to go momentarily out of postion when brakes were applied. It would not unlock until I came to a complete stop. The springs are still supplied by Case/IH.

I have a big 400 that I had to gut the tranny and start over. I used the best out of 4 traanies and ended up with a row crop 400 with an orchard ring and pinion. She will run about 25 MPH. I'm the Shop Manager for a large farm in south Florida. The farm mis 29,000 acres with 8,000 acres of Citrus. I understand what you are talking about. I just thought when the ring gear carrier was changed by my uncle years ago he just did not shim it correctly but you are probably right about the thrust washer. Thanks.

If you have that much play probably the fibre spacer has failed between the ring gear carrier and the LH side gear, this will indeed allow the backlash to go way out of spec and could cause an expensive repair if not corrected. You probably have seal leakage as a result of all the shaft movement. Replacement thrust washers are steel and are selective to set your spider clearance then the whole setup procedure must be done to reestablish the backlash and differential rolling torque. You need a manual and a dial indicator to do this any kind of right. PS the whole rear needs gutted to get the bull gears out so the side gears can be removed, Hope you have some good mechanical skills. mEl

Today's Featured Article - Recollections of a John Deere GP - by Charlie Cook. I grew up on my dad's 280 acre general farm in Western Michigan. Dad's only tractor when I was very young was the old GP. My first recollection of this tractor was when dad allowed my brother and myself to ride on the tractor with him driving. One of us would sit on the left fender (away from the clutch) and other would sit on the gas tank and hold onto the crankcase breather pipe. ... [Read Article]
