806 RD Injector Pump

Recommended Posts

Picked up an 806 from a local dairy farmer who got done milking.  Has a leak off the back of the injector pump on the return line. Looks like the pump needs to come off to replace a grommet...

Anyone one know the timing procedure for removing/installing an RD pump? Seems a little different from the stanadyne roosa pumps I remember.

Sorry for the delay. Not sure why this didn’t send the first time. 
 

Pretty strait forward. Roll the engine over by hand until your flywheel and injection pump marks line up like the first picture. 
Take the front pump gear inspection plate off and then remove the three bolts off the timing gear. Now you can just take the pump mounting bolts out and pull the pump off. 
The holes in the gear are slotted to be able to adjust the timing. 
let me know if you need any more pictures from the RD service manual.

Here’s the steps to put it back together starting from where they installed that throttle shaft. 
the whole thing looks pretty complicated but maybe once you get started it might not be too bad. 
I didn’t include all the pages dealing with the actual pump as I figured you are probably not going to be taking that apart. 
let me know if you need anything else. image.thumb.jpg.141780040555964dd2727329f030c771.jpgimage.thumb.jpg.212dded5c2454ab248442b362238bfde.jpgimage.thumb.jpg.5c3313b0991b8ab3b00d0ae3eb932a7e.jpgimage.thumb.jpg.0b00aad392f660c8070fcd70b54e8ea5.jpg

Thanks again. Think I may let the local injector shop reseal this one. Not a lot of replacement parts out there if I mess it up ?

I agree with you on that! The local place wouldn’t touch mine though, had to send it to Iowa. I’m glad I did.
