Injector pump problems international 454

Hello, I have international 454 that has always cranked and run real well. I started getting diesel in the crankcase so I took it off and had seals put in the pump. I put the pump back on and now it won't start. I talked to someone and they said might need to take pump off and turn pump revolution. Also, the guy that worked on my pump said that the two lines one from filter and the other on top of pump. He said that you need to make sure you put the bolts that hold the lines are put in the same place they come out. One of the bolts has a bigger hole up through the bottom than the other. Can someone tell me which one goes where? In case I have them mixed up.

Hi, I believe you have the pump 1 revolution out of time. See this post:

Also I believe your 454 would have a Bosch BR pump so see post from archives from DieselTech:
EPVA distributor pumps had 3 versions, AR, BR, and CR. AR and BR had the delivery valve fittings at an angle while latest CR type had fittings that came out straight. Pumps will interchange but injection lines may need changed or old line bent as needed to fit. Also CR inlet and outlet line bolts are the same, while AR and BR use a pressurising valve in the return line. Bolts are the same size, don't get the wrong bolt at the inlet. May not start or will barely run if the pressurising bolt is placed at inlet banjo.

So the bolt that goes in the inlet fitting will allow Diesel fuel to flow freely. Turn bolt with head down and pour so Diesel fuel into opening at top and fuel should run out the holes in the bolt.

The open bolt is at the inlet at drive end of the pump. The restricted bolt is at the top, return line.

Thank you for your help. I tried what you suggested. I turned pump 1 revolution and I think I have the correct bolt in the correct banjo. Now it still will not start. I am not getting diesel to the injectors on the motor. I am assuming that is the reason it won't fire. It appears to be getting diesel to the inlet banjo at the filter but very little diesel at the inlet banjo on the pump. I also checked the return banjo and no diesel there. I have loosened two of the outlet lines to the motor and no diesel at all. I loosened one line at one of the injectors on top of the motor and of course no diesel there. Before I have to load a non-operational loader tractor on a trailer and take it to a mechanic. Is there anything else I can check myself?

Hi, I assume you have the STOP/START/RUN cable adjusted correctly? If you have a compressed air gun, stick the air gun in the fuel tank inlet and take a clean rag and seal around the air gun and slightly pressurize the fuel tank. With all 3 injector lines loosened at rear of pump and with throttle wide open, STOP/START/RUN on START position, attempt to start engine and see if there is any fuel coming out of pump injector ports. Once there is fuel at pump ports then tighten one line at a time while while attempting to start tractor.
NOTE: DO NOT CRANK starter for extended periods of time without a cool down period. Also be careful of high pressure Diesel fuel in injector lines.

Also when you do get white smoke out the exhaust and no starting then you may have to rotate the injection pump 1 revolution as it may have been in time the first time and the real problem was no fuel.
We have had a 454 since 1974 and have re-sealed the pump 3 times. The only time we had a problem is when my brother attempted to change it by himself. He remove the cap screws on the drive hub without scribing marks. The engine still started and ran but lots of smoke and Diesel slobber.

The start/stop/run cable doesn't work and another cable has been installed and basically it is only used for is to pull to stop engine. This must have been done by the previous owner. I don't have access to a air compressor where it is parked so I will try to come up with one. Thanks for your help. This tractor cranked and ran so well (even in cold weather) before this pump issue so I know it has to isolated to the pump.

Hi, with reference to photo of injection pump, the START position is where the fuel control lever just clears the end of the Shut off plunger. In the START position additional fuel is delivered to the injectors.

Hope this helps

You have received a lot of good information. Until you get a good full supply of fuel from the tank to the pump you have nothing. First things first.
