Allis_B12 Posted October 23, 2003 Posted October 23, 2003 Hi everyone, I have a problem with the 3-speed tranny in my B-12. Before I took it apart, the unit worked well. It was quiet and would pull uphill. Now that it's all back together, it's not working right. In third gear, the tranny moans when picking up speed. It's fine in the other 3 gears. The tractor also won't climb any hill in 3rd, but it did before. I checked the tranny oil. The oil is thick and has air bubbles in it. Can anybody tell if this is a belt/clutch problem or if I have to go inside the transmission? Thanks for your help. Joel
DaleC Posted October 23, 2003 Posted October 23, 2003 Joel, Without knowing what you have done. . .let me hazard a few suggestions. First, It is not unusual for these units to have a moan or gear whine to them. Both my B-12 and the Big Ten do this. It may be that you just never noticed it before. It should not be LOUD but a whine none the less. As far as bubbles in the Oil, that is because it is splash oiled by the gears turning. I would be surprised if it did not have bubbles. I would guess that the not pulling under load is a belt problem. Readjust your belt tension and brake as they both work together. If you change one, check the other adjustment back and forth till you have them set right. I assume that when you had the tranny broken down that you had to remove the clutch. Make sure that you have it reassembled in the proper order Make sure that all the Keys are in place on the tube axle at the differential (right side) and at the hub on the left side. Check these items out and then if it is still a problem, we will all have a go of it from there. Good luck. Dale
