Injector pump problems?

[Bobby Dungan]

My 135 Massey diesel died while using it. Assumed fuel system. Replaced rusty tank,new lift pump,new filters. I get fuel to injector pump but can not get fuel to bleed through it. I have followed bleeding procedures several times but no luck.

Here is the manual for your injector pump. Just in case it may help.

Thanks. It may help me to see how the thing works to see what steps I need to take

The injector pump manual goes into exquisite detail so it should be helpful.

I've got the same issue on my dad's 801 Powermaster...
I am trying to find a diesel injection service professional in the Hickory area right now that can do a rebuild on my unit...
There are several on E-bay that offer those services...
I am not mechanically inclined enough to tackle rebuilding an injector pump but I can take it off and make sure it is in time...

I guess I have come to the same conclusion that my pump must me rebuilt. I too have to locate a rebuilder in my area

Truckpro down on 49 below I 20 has a fuel pump shop that can rebuild it.

Good choice. Injection pumps are typically very complex and require specialized tools and techniques to service.

Hi Bobby. I have been working on Mf injecjection pumps for more than 40 years. DPA pumps, in my opinion, the best ever made. However the most important and obvious reason for liftime service of any injection pump is clean fuel.You say you have replaced a rusty fuel tank. Water in fuel is fatal for any pump and it normally causes a seized hydraulic head in the case of a DPA pump. To determine if it is the case, remove the transfer pump endplate at the back of the pump and then turn the engine or the pump itself if it is already been removed from the engine. If the transfer pump rotor does not turn, you have a seized head. If it does turn, then you will have stuck pump plungers. To rectify this the pump will have to be stripped an the plungers loosened. This will have to be done by a pump mechanic.
To come back to DPA pums. I have, through the years, done many conversions where I raplace any mechanical injection pump with a DPA. The majority were replacements of the Bosch VA pumps on the German made International tractors with the Neuss engines. On two occasions I have replaced Bosch VE pumps on the 3 liter Tata ldv's with DPA's.
