need 2t90 injection pump

thepumpguysc · Jul 25, 2019

That's some good "out of the box" thinkin right there.!!
I even tried using a bolt, threaded into the return hole on top & using a puller THAT WAY.. no luck..
Mine was VERY STUCK & thought I was going to strip the nut w/ the Hoye tool.. but it finally came out.

I did find it easier to remove the studs, for more wiggle room when your twisting it.. HEED MY WARNING about crushing the inlet on the injector.!!!
The thing about that tool from Hoye is, its so simple.. but at the cost they're selling them for, YOU COULDNT get one made at the machine shop for that price.{?}

machine shop said injector is really stuck and cant get it out of head. any ideas?

IDK if u can see the nozzle from the other side of the head but I think u can..
I've had Yanmar Marine heads that I've "beaten" the nozzles out before..
The tip/nozzel is naturally not going to be any good afterwards but that's not a big deal.. the model # is stamped on it..
THEN u have to cross the mdl.# to a part #..
OR BUY THE FRIGGIN TOOL..

thanks for the tip. that is the direction i am going. I'm driving them out with a 1/2 inch socket. looks like im not the first. nozzels should be ok.

Why not just buy the friggin tool from hoyetractor.com? It's a good tool, everyone uses it.

Maybe he doesn't want to spend the money? Not sure how much a nozzel is if it's destroyed though? I probably would buy the tool myself.

its complicated... i just spent way too much money with them the other day and i was expecting the machine shop would be able to handle it. now time is a factor because i want the machine shop to get the head back so they can fix it and i can put it back together. the nozzles are fine.

Did you beat them out?

I personally would be nervous beating around precision machined surfaces and something one slip of the hammer I could ruin something.

i soaked them in acid from the top and bottom to break up as much rust as possible. then with WD-40 I beat them out using a socket as a driver. the prechambers are pretty stout pieces. it looks like i was not the first to do this on this motor.

Theres nothing wrong in doing it that way.. not ideal but..
Just be sure to replace ALL the gaskets in the pre-chamber... otherwise you'll get a combustion leak around the injector..
The gaskets are about 1.00 apiece so don't scrimp out..
Just go to the Hoye tractor site & buy them.. or theres Fredicks..
I haven't spent much time on the Fredricks site but the Hoye site is EASILY navigated.. & u wont have any problems in finding the parts u need.
U went to all this trouble getting the injectors out.. what do u plan to do w/ them.??
