anyone ever done this? the manual doesnt give much detail.

You all can chime in on this one if I am talking nonsense.
Which pump exactly are you asking about ?
My 617 has one manual pump attached to the Injection Pump.

I don't have a pump in the tank at all.

Manual pumps are cheap and replaced instead of rebuilt.

Injection pumps are rebuilt by facilities with appropriate tools
and equipment. I have never seen any documentation on the
Injection pumps.

You would think it would be explained somewhere for us do it
yourselfers.

Good luck ever finding instructions on how to rebuild the pump that aren't copyrighted.

Bosch (of Germany) is VERY VERY protective of all its documentation and only authorized service centers usually have the books on how to fix/adjust the pump.

I worked for quite some time and the only thing I could pry out of the injection pump shop was a parts layout diagram...no names or anything though...

Every one of their documents says something along the lines of "not to be copied for 3rd party distribution" or something like that.

GOod luck but honestly unless you are familar with servicing injection pumps, I wouldn't try doing this one yourself. Why do you think it needs to be rebuilt?

Assuming you're referring to the injection pump, there's no way to DIY "rebuild" these units without the use of a flow bench for precise calibration and synchronization. I've tinkered a bit with my growing collection and I don't recommend even bothering to invest the energy into opening them up, without very specific and well planned purposes. More trouble than it's worth.

thanks for the input guys, I guess I shouldve been more specific. When I say fuel pump I mean the fuel pump. the mechanical pump on the side of the injection pump, NOT the primer pump that is bolted to it, but the actual pump that the primer pump screws onto. The manual only says renew pump but gives no instructions on how to do so. I had to track down the kit to do so from a dealer in santa barbara (thanks Randy!) The kit consists of a few springs, washers and O-rings. I'd like to get some viton O-rings, might be a good idea for you bio guys too.
thanks again!

When you want to dispose of the injection pumps, please send me a PM.
