Gat Her fixed !!!!! Runs like a top. The parts pump that I had gotten had a differant style throttle tube, it looked the same but the ports were a little differant. So I sent it of and for 200 bucks was able to get the tube fixed and re calibrated, works great and thanks for everyones help.

I did not swap the pump just the tube. Both tubes were held in by a set screw. On the end of the tube was a flat end shaft that could only go in one way, looked very simple. The tube appears to be a different part.

Ok I found a parts pump. And the part that I needed for the throttle, it was held on by set screw. Got everything on and tried to start motor and am having trouble getting fuel to the engine now. I have cracked the fuel lines to try and get the air out quicker, the engine acts like it wants to start...

Ken, this pump has a two bolt flange, appears to be smaller than other pumps that I have seen. The Tractor runs great! On the bottom of the pump there is an arm that sticks out about one inch long, then there is a gear box where the throttle arm hooks up to the gears that drive that shaft in and out...

I have an early model 450 bulldozer. My injector pump started leaking fuel behind the throttle linkage housing. No big deal, just tighten it up. Well I broke the little stem off. That is on a cbc 431---3al model pump, can't find one any where. Can anyone help?

I have a Roosa Master CBC model injector pump that was leaking behind where the throttle linkage hooks up. Went to tighten it up and broke the housing completely off, the only thing holding it on wad the plunger that gauges how much fuel is dispensed. Seems like a simple fix but that piece is made i...
