433I not pumping fuel

I would rather not give it either to get it to fire. I've got an older orange 433I that Has an operable pump, so thought of doing a swap... I removed the black engines injection pump timing window, but I can't see both timing marks?? I see the stationary mark. I've had my wife turning its flywheel with a pry bar to no avail I can't see the rotating disc timing mark. Do these marks wear off over time?

I have the same problem on my 653 Dozer. Rebuilt injector pump and injectors with clean fuel lines. Will start on ether and die when I don't keep spraying ether in it. Has the compression gotten so bad it won't stay running??????? I so want to hear this Dozer run on her own.

Yes Sir. I only get a little bit of squirt of fuel out of the injector lines. Do I have a small air leak somewhere. The guy I bought the dozer from said it did the same thing with him, with the old pump. I have replaced the pump and had the injectors rebuilt, but to no avail. I timed the pump at 24-26 degrees and did everything like the manual says. I have worked on everything from Briggs and Stratton to B-52 engines.........and I am at a loss. I only have 7 gallons of fuel in the tank.............I do not have gravity flow out of the fuel line, but if I pump the primer plenty of fuel comes out of the line. Any help would be greatly appreciated. Could I have blown the head in the new injector pump with it being timed 180 Degrees out? Gracious I sure hope not!!!!!!!!

who did the pump? or was it just another used pump? 

yep, you slide the pump back off the shaft. It does help sometimes to pull the gear access cover off the front so you can help position things when putting back together. 

I am pretty busy, but I always seem to get them done lol!

looks like you found the pump marks. lol! The punch mark is not as important in my opinion, since the main concern is that the crank pulley is where it needs to be, and the lines in the pump lined up. The problem can come along if the front pulley has slipped. Being it's at 15, I'd say it's ok. It is common to see them lose a couple degrees over time. That is why I like to suggest people actually timing it when re-installing a pump, instead of simply marking the housing, and putting it back exactly as it was. 

update on my AC653 Dozer.............She is running!!!!!!!!!!!!!!! I had to remove a screw from the side of my injector pump to relieve an airlock. Pumped her up with the primer with the lines loosened up. Turned her over and she fired up and smokes like a freight train. I was so happy to see it breath life. Got to get tranny fluid to see if she will move tomorrow. Left pedal is stuck up the right pedal goes to the floor. One step at a time. I hope she moves and stops without alot of problems other than waking up from a long hibernation. Thanks to all who have helped me with her. Dave and Central Fuel Injection Is Esterville, and Ivan at Sumpter for the Troubleshooting procedures. Thanks a milliion to everyone of you folks!!!!!!!!

Ed, I've never pulled injectors before. Could you please give me the procedure for removing these injectors? Thanks

Here is a picture of one of the injectors on this black 433I engine 33-10877.

Somewhat typical. Do not disturb the copper tube or you will be pulling the cylinder head. Clean the tube with a rag and gas, brake clean, solvent, or whatever you have. Blow out the hole, and hope for the best.

Drop a short 1/4" screw into injector hole with head up. Use a 12 gauge shotgun brush to clean hole. With a screwdriver hold the screw down while blowing the crap out of hole. Use a magnet to remove screws.    MACK
