BGB Problems

[Simplicity85]

On my 64 LL smokey tractor the PO never cared about it or did did mantance on it. So I was out driving it the other day and It was driving fine and then it just stopped driving and I jumped of and look under the seat pan every thing was still turning and stuff I think the BGB went out do you? If so How can i fix it? or just swap it? jace

If the pulleys are still turning, your BGB is good. You may have sheaed a key on the trans input shaft or something in the trans. If the engine is running and the pulleys aren't turning, it would sound like a BGB or driveshaft problem. I would think there would be a fair amount of noise from broken gears, etc. hence my thoughts on a bad key/keyway. Good luck!

What brett says makes sense. I had 2 with bad bgbs. One would stall the tractor out when you let the clutch out. The other sounded like the gears wanted out in a bad way!

Well i think its not the rear end because It still goes into all gears and does not roll. and It rolls fine when in neutral.

Check the key on the input shaft on tranny.

Check the roll pins in the diff gear Sounds like you sheared them.

Bevel gear box

Osenga has the drive shaft break before not that means anything since the rear end still turns

check the outer coller that holds the hub on the differential side. had one come loose a few times and hub slid out enough just to make it not move. i thought i broke something major but was just the coller sm01.

Bevel gear box. Only on the large frame tractors. It turns the rotation of the drive shaft 90 degrees to be parallel to the rear end. It powers the trans and the center PTO's.
