I had to pry these out. I'm not sure if they are rebuild able. The shop I took them said they weren't . NH can't get them, and the shop said no one had them. I did find a guy that said he might have the bodies. Just wanted some thoughts or ideas. I'm new to diesels and injectors. Thanks for any suggestions in advance. Nik

Maybe check with these guys. The NH number is 87801538. It is a Lucas injector #LRAB01601A.

Not sure those website links are loading correctly. It was for Spencer Diesel in Spencer, Iowa and Wimer Fuel Injection in Sandy Lake, PA. Both of them list the parts on their websites, but I'm sure you need to call about availability. Both of them do only injection pumps, injectors, and turbos and are known around the country.
 
Well, after $128 an injector to rebuild and a head job for $350, I hope to have a new machine. Hey a guy can dream🤣🤣. Ok maybe not new, but certainly much better running. Also, if anyone has a 180, injector bodies are very difficult to locate. It took two local shops finally. First one said not available, 2nd shop brought them back to life. Thanks , Badger Diesel in Salem, WI. Hope to have this up an running by the weekend. Keep you updated.
 
Cool, Salem WI. Spent many a day there in my younger days after skiing Wilmot Mountain.
Congrats on the fix.
 
Never skied wilmot, but plenty other hills in WI. Went out west and skied all the resorts, never wanted to go much after that, lol. Skiiing ice is no comparison to powder.
 
So I got my cylinder head installed or I thought. I put first injector in slips right in . 2nd and third won't go. I unbolt head and discover the old body welded its self to the injector bore. Now I'm out of ideas. I'm gonna try running a 55/64 flat bottom drill, which I'm gonna have to make once I get it from Amazon. Anyone have this issue ? Open for suggestions ?
 
I believe that I would take it to the machine shop that serviced the head ,maybe they just missed that problem?? certainly they are better set up to do it than your average shade tree. from the hole that was open they can get all the required measurements to bore bar out if necessary.
 
Yeah, I never told him to check that part out. The injector is on an angle definitely gonna need a mill to bore it. The question is is it a critical dimension? The hole has clearance for the injector body to slide in. The smaller diameter dimension by the tip of the injector looks like it is more critical. I believe at the end of the day the copper washer seals the injector to the combustion chamber. Wish my. Bridgeport was up and running, might be a great reason to get it functioning now. Anyways, gonna try the drill and see how it cleans up. Guess my tool and Die days are paying off . Will update on how I fare.
 
do you think that maybe now that the head has been tanked( I assume) that you could thread the remains of the injector and use a slide hammer to knock it out?

I think the smaller portion which mics out at .664 is either corroded or or galled up or something. I ordered a .666 reamer which I measured the bore diameter at. Gonna try to carefully run a reamer in there and clean it up. The larger bore is the more corroded with pieces, might try to ream that out as well. So much for getting it running this weekend. Atleast the weather isnt gonna drop too soon. Oh well.
 
Seeing as you have tool and die experience, yes the copper washer is the sealing point and if you just have bits and pices of the body in there have you tried a pick to see if you can flake any of the pices off, it may clean up easier, it could be carbon holding it , emery cloth fitted in the slot of a 1/4 dia cotter pin chucked in a die grinder makes for a quick flap wheel for small bores.
 
That's a great idea, never thought of that. I managed to cut an angle on a drift punch and chisel out the portion that was left in there. But there is definitely something holding it up. I'd probably have to weld a stub since I need to reach 2.5-3" do in the bore. The head guy said bring it back, but he doesn't know if he has a .666 reamer. Thankfully Amazon has one .

You might be able to get a wire brush for a pipe at a plumbing store they come in 1/2" and 3/4" and up, they normally have a twisted wire handle with a loop like a fly swatter for a handel, I cut the loop off and spot weld the ends together, or a wire brush for shot gun cleaning also, the pipe brushes seem stiffer.
 
Ha, a quick check on Amazon for wire pipe brushes, and they have a set for $9 with 1/4" here ends
 
Yeah, being a pipe fitter the first thing we do is cut the handles off those brushes and chuck em in the drill. If I have to clean more than one fitting by hand I cut the handle off and power brush the rest of the job. Got my reamer , hopefully this will remedy the problem.

Okay I made a jig to locate the reamer concentric to the injector bore thinking there should t be much matl to take out. This is the picture of the reamer cutting a new bore. Something doesn't seem right. Before I go further I wanted any of your guys opinions. The original injectors were literally gone. I double checked the bore on the one that does fit. With out a different plug gauge set or something I can't accurately tell what is currently there. I would have thought the rusted parts would have broke free from the cast iron. I'm gonna take it to the head guy tomorrow for his ideas. I think I'm on the right track. Open to any suggestions or thoughts.

I would think that the head guy would know, and I would take a good injector with you.
 
Well we or I should say he determined the 5/8" dia part of the body broke or rusted off and welded itself to the head. He's gonna fix it and was excited to work on it. Keep you updated. Nik
