Roosa Master Manual

901Diesels

New User
Anyone have or know where I can get a rebuild or parts manual for the Roosa Master injection pump on my 901?
I found the problem with my pump but not experienced enough with these to know the proper description to look for replacement parts.
I have see diagrams on this site - one shows an exploded view - for lack of a better description the shoe on the throttle shaft that holds the governor spring is worn and loose. It doesn't keep any pressure on the spring. Any help is appreciated. Thanks
 
It WILL be loose, as that pump is shut down by the throttle shaft. That's normal on that pump application. Slack is taken up when the engine speed is increased by the throttle shaft/lever assembly.
 
When you move the throttle to "wide open/full throttle" does it tighten up??
IF YES, its working properly. BTW, what IS the problem?
The manuals are ALL OVER the place on ebay.
 
There is a little more to repairing pumps than simply having a manual. It takes years of success, and failures to get this art down. If I bought a book at Lowes that shows how to mix mud and lay blocks would you feel comfortable enough for me to lay block for the new house you are building? If I did it you would save money, but what about quality, or how long will it last? Pump repairs are NOT expensive. Maybe in your area, but not everywhere. If you use the internet to ask questions about a pump, than use it to find a reputable pump shop that isn't expensive. Most repairs don't take long either. Make a few calls and ask questions. I think you will be surprised. Good luck Al
