5.7 diesel up and running

[dieselolds]

Here are some pictures of all the parts on a table after taking the pump apart.Everything is pretty good except the Bristol drive bolt and advance piston due to the rust.The Bristol drive bolt is brittle and easy to break.I usually place a torx bit into the bolt with a couple small whacks of a hammer and then use a impact gun to whip it out.A ratchet will not work.I’ve seen them split and fall apart when trying to use a ratchet.

Curious if this bristol bolt is present on a DB2 IP for our 6.2's / 6/5's. where is this bolt located on or in the IP?

It’s only found on olds 5.7 pencil injection pumps along with older John Deere and case roosamaster DB and DB2 pumps.The 6.2/6.5 just has a small pin that slides into the cam ring.This particular Bristol drive bolt threads into the cam ring on the olds pencil pump.The olds diesel with poppet injection has the same steel pin as the 6.2/6.5 DB2 pumps also.

The 5.7 pencil pump has no mechanical light load advance lever on the outside.So thats the particular pump with the threaded Bristol drive bolt.

Thanks for that. at some point I would like to take the IP that I have mounted on a 6.2 and try going through it my self. I figure as long as I don't mess with any adjustments I would be able to reseal it along with check for wear and tell if it's fubar or worth running / full rebuild if needed and not have to pay a shop to rebuild only to find out it's too far gone.

I have no clue what the going rate is for a rebuild is vs just getting a new or exchange. One day I would like to have a good spare for when that time comes. maybe even get this one done, install and get the current one done so I'd have the truck alive for the long haul.
