M-H 44D

I'm getting diesel in the crankcase on my 44D. I think someone did tell me that it could be getting through the seal on the front of the injection pump but I see in the I&T Manual it could be a leaking throttle needle diahragm, leaking gasket under delivery valve or a worn plunger. The injection pump is a Bosch PSB Pump.

Any advise please

Thanks

Alan

Alan,
 I would put a new seal in supply pump on outside of pump. It is attached with  four  7/16" cap screws. Pretty easy to put in . Its about 5/8" OD and 5/16"ID. Any promlems call me 319-240-2766 Dennis

Thank you very much for your advise. I've got the tractor into the workshop. I will let you know how I get on

Thanks

Alan

RE:M-H 44D

More problems now. The tractor doesn't charge. The regulator has three components. Can just one of these be changed or is it a new regulator ? The regulator is fiited on the bulkhead under the diesel tank.

The other problem that I have is that I can't get a spark on the flame heater. I have power to the coil but nothing coming through it. I guess that means a new coil does it ?

I'm waiting to get a seal on the lift pump.

Thanks

Alan

Do you know where I can get a replacement seal for my lift pump. I have been to my seal suppliers and they tell me it is a special Bocsh one.

Unfortunatly the seal I took out doesn't have a number on it.

Thanks

Alan

RE:M-H 44D

Does anyone have a parts book for a Bocsh PSB Injection Pump? I need to know the part number of the seal thats goes on the drive of the fuel lift pump.

Also does anyone know where I can get a coil for a flame heater. My tractor is a 44D but i guess 55's  would be the same. Terry Kessel doesn't have one.

Thanks

RE:M-H 44D

Hello Dennis,

Thanks for the information. I have struggled a bit with this seal but I got a part # yesterday which I am told is PK 7910 and Terry Kessel can get one. The only other thing I need is this coil for the flame heater which is proving difficult but I can live without it

Thanks again

Alan

RE:M-H 44D

I have today got my 44D running again

Thanks for your help Dennis. I was able to get a seal for the pump from Terry Kessel ,who is a very helpful man.

I would still like to replace the coil on the flame heater but can't find one.
