Stanadyne made many variants of the Roosa Master design rotary injection pump. Let's start with the exact model you are working on. They usually say something like DB2 or DB4, etc. There may be a sub-version number as well.

A word of caution: opening an injection pump without knowledge and specific calibration tools can render a pump useless and or damage the engine it is installed on.

Sounds like you are talking about the master flex ring. It depends on your governor cage whether or not the ring existed in the first place. If you found pieces of it in the pump, then it likely needs one. If not, you might have a pump with the solid weight cage. Some reseal kits have the master flex ring and some don't. See the article below for more detailed information about this.

Thanks for the help.When I open my pump it was only left 1 small piece around 1 of the bushings so I rally don't know what it really looks like,the seal kit that I got don't have anything looking like that .

I did read here a post from Gastrap here is the post



There's a rubber ring that holds the governor basket onto its drive plate. It disintigrates and contaminates the pump. If it runs this way too long it will destroy the pins on the 2 steel parts. The replacement ring is of a better material & lasts longer.



I really don't know what to do here. Do you know where I can get this ring or the solid govenor cage
Very helpful that post on that ring,now I know that I need one

There are multiple sellers with them available but that listing should give you an idea of what to search for.

I would simply replace the flex ring with the new style part and be done with it.

Hello. Working on the same exact pump. The kit I bought (on ebay) contained the flex ring you are speaking of. It's a white nylon looking ring that seems to be a little small, but actually stretches real well. You have to clean off the remnants around the rivets where the old rubber ring was and stretch the small holes over the rivet heads. Its really not that difficult. I purchased the last three kits from this seller, but others are available. Here's a link:

While I'm here, does anyone have the roller to roller dimension on this pump? (DBMFC 433-1LK) Thanks and good luck.

BTW, Cancel that request on the prior post for a roller to roller dim. Prior post was correct: These guys are the poop... Awesome customer service.
