pump rebuild

Post by JAMES ADKINS »

I have a good operational ip that i plan on resealing. If i choose to do the complete teardown, are there any mods that can be done to pump to enhance performance? I know Giles does some kind of hopup but is there anything a home emechanic can do? thanks :)

There are many things, some I have done and some I haven't. Governor mod is fairly easy to do. There is something about grinding the case away on the advance piston, but I haven't done that. Try searching here for some info.

The FAQ and IDI sections is where most of the info is located that you will want. Search the entire forum though.

Ok i did rebuild/reseal the pump but i chickened out on the mods. Power was'nt really an issue but i really like to havea smooth operator. My pump i'll be replacing has a surge in it so i just want that to go away. Anyways wish me luck that i did a good job guy's. :)

Is your a TD pump?
I had a surging area in mine and the governor mod got rid of it.

Next time you do a front seal, you may attempt to buy the seal locally from a Bosch shop. Why? Because, sometimes, the shop will allow you to rent the front seal puller for a few bucks for several hours....and if you use this tool, it takes about 1.5 minutes to very safely pull the front seal!!!!
I have a local shop who does this and, yes, his price on that little seal is about 3 times that on ebay. But, it is entirely possible to scar your input shaft if you are not super careful.
In order to cut corners (financially), I will do like 3 pumps at once...buy ONE seal from him, rent his seal extractor, have additional seals on hand, and do several pumps in assembly-line fashion.
Hey...just looking out for #1 here!!!!! :lol:

If you have the pump completely apart, it's a 30 second job to pop the old front seal out. I prefer this way because there's no risk of scoring the shaft.
