951b torque converter leaking

If it's leaking from the front of the torque converter the seal needs to be replaced. Why do you suspect the transmission pump if otherwise everything is working?

Thank you, have no idea, I haven't climbed under it yet

It doesn't seem to run out all the time, I've looked under it while running and don't see anything, seeems after shut down, there is a puddle the next day

Hi, Butch Foster.
There is something stirring under a huge bunch of cobwebs right at the back of my skull. I think the torque converter on the 951bs is on the front of the transmission. If I am right, that front seal would be accessible by removing the connecting couplings and pulling the flange.

I am sure that somebody will either back me up or shoot me down in flames. They always do one or the other on here. Thankfully, 'cos I will learn from either.

Correct Deas, the seal is accessible that way, but aleak is usually a sign of the bearing wear, which causes the converter input seals to leak internally and that can cause overheating of the converter.

Hi, Catsilver.
I was not aware that a leaking seal there could a result or indicator of bearing wear. Never had to go into that area of the jiggers and was basing my answer on observations of several 941Bs, on which I spent a good few very enjoyable hours.

Thanks for the extra information.

First order would be to get the external leak fixed.
If that doesn't cure the heating problem there are several other possibilities:
1. Fouled torque converter oil cooler
2. Excessive leakage in the transmission (insufficient oil to torque converter)
3. Weak transmission pump (insufficient oil to torque converter)
4. Excessive clearances in the torque converter (there are no internal lip type seals)(excessive oil build up in the torque converter housing)
5. Failing torque converter (look for aluminum particles in the oil filter)

Firstly the 951B is fitted with the 330C engine not the 3304, the front seal on the case can be replaced without to much trouble, it will pay to lift the loader frame right up and support correctly, you have to remove the drive joints (Pucks) then pull off the flange that will move easily, the seal can be dug out without much trouble, the torque cannot cause flood conditions as it's integral with the transmission, the common issue with over heating is the oil coolers, the water has to pass from the water pump through the oil filter cooler to the transmission cooler then into the engine, the engine would also show high temp's, the 951C had the air cooled transmission cooler built into the front Radiator. tctractors

Hi, tctractors.
I have still yet to operate a 951 of any series. How-wevver, i was told by a bloke who had owned and operated several Bs and Cs - along with a dozen or so 941s - that the Bs were prone to overheating while the Cs ran cool azza cucumber. Maybe that separate transmission cooling core was the difference? Or did they also have a bigger radiator?
