Roosa Master? are these extinct or what?
Roosa Master? are these extinct or what?
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?
Brandon don't look to Deere for injector pump repairs .Find a neighbor hood contractor and ask him about what injector repair business to go to.Look several up on line but shop around and never take extinct ,no way or none for answers.Ask at a local tractor wrecker even look for other old Deere's and stop in to ask the owners and pick there minds.No questions asked in sincere honesty are stupid ones .I find injector pumps ,injectors ,torque converters and hydraulics take people in that profession to do that specific job.After months of injector problems I went to the closest injector shop just after the John Deere dealer told me you don't repair these things .I set my injectors on the counter as a mechanic form that Deere shop was setting off a set of larger injectors to get worked on .My injectors were repaired and set in hours and I never went back to my dealer for pump or injector problems after that .I didn't complain to them but I have never trusted them for more than filters and wear parts and they know it .Good luck .Digitup.
Hi Brandon-
If you search the archives on this bulletin board with keywords of "CBC" and/or an author of "Jdemaris", you will find a wealth of information on these pumps and the specific questions/information you will need to know when you go to get them repaired or buy parts for them. Jdemaris is a former Deere mechanic who posts occasionally on here and is very knowledgable on Stanadyne injection pumps. The information about the conversion to a DB pump can also be found in those archives.
Here are a couple of relevant posts- the first one starts off with DB pump information but has some CB pump information later on.

There is also a Deere manual dedicated to the these pumps if you want to learn about them. There was a link on one of the posts to a downloaded version of that manual. Lavoy also mentioned in a pst about maybe having reprodution manuals made. If you can't find it, I believe the manual can still be purchased from Deere but you would need to confirm it (SM-2???). You don't need to have the manual if you are going to have a shop repair it, but it helps to know some specifics to ask the rigth questions.

there is a kit to change them over to JDB series but I think you have to do some drilling and tapping and there is a special adapter involved as well your DB2 series pump is an up grade and it should work fine if you can kit it on the engine .I think a DC series pump is a whole other story so you are lucky there .Digitup.
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 but it want take off. Any suggestions?by the way this is the original pump and was running fine before all this.
