Removing Injectors, 4020

2510Paul · Dec 26, 2018

I have a 1971 4020 PS I wish to remove the injectors from. I bought this tractor out of MI a couple years ago and have only run it enough to park it in the shed but it sure seems to need a fuel system overhaul, tank cleaning, filters, injectors and pump in my mind. While this tractor looked nice when I got it I have found that many of the bolts are rusted tighter than any other tractor I worked on. I suspect it sat outside a lot.

It also needs brakes on the right hand side so will do both. I already re-built the seat mechanism and have started on the bound up throttle linkage.

Anyway, what suggestions can you give me regarding removing those injectors? I borrowed a tool once from a JD Dealer only to break it. Bad experience. Should I just start soaking them in penetrating oil. I assume I will have to find a tool to help remove them. Any Suggestions?
Thanks.

Start soaking them,,when you start working on it see if you can get them to twist a bit to break them loose,,prying on them hard will bow them, which ruins them,,if you get one that will not come out weld a nut to it and use a slide hammer,, I know this sounds nasty but it's better than pulling the head.

As Tim said, they can be stuck bad if the top compression seal did not hold. If it leaks the lower carbon dam WILL blow too and pack the injector tight in the bore over time. What works best is to carefully lift and twist back and forth, if not stuck they will come out.
