injector rebuild for IH 806

ironandsteel · Jan 23, 2011

My 1963 IH 806 diesel needs to have its injectors rebuilt. Any suggestions for a good place to have them rebuilt? I imagine I could do it myself, but I don"t have the equip to test the pop pressure.

I plan to call the local IH/Case dealer just to get the upper limit on what it will cost. They are always crazy-expensive on parts.

I find lots of places on the web that do injector rebuild- but maybe you guys can recommend on in particular. If I can find a local shop that is cheap and good, that is better.

I am in the proximity of Leesburg VA, Winchester VA, Frederick MD, etc.

Check yellow pages for nearby diesel injection shop.

If you're not concerned about somebody cleaning the exterior to make them look new - I'd make a few calls and see who will just put the new nozzles tip on, and forgo the cosmetics.

It takes less then 10 minutes each - to install a brand new nozzle-tip and test.

New Bosch nozzles for IH 806s cost around $45 each from Bosch and half-that if no-name Chinese.
Bosch # DLL150S260

It's also not too difficult to make your own pop tester from a hydraulic bottle-jack. But, if this is a one-time thing, it's probably worth just paying somebody $20 each to install new nozzle-tips. So, in my mind - with no cosmetics involved - you ought to be able to get new tips installed for a total price around $65 each.

Had several JD, MM and IH injectors/pumps done at the local pump/injector/qovernor repair shop. They seem to do great work but darn expensive. Talked to the local CIH shop foreman and believe it would have been cheaper to have them do the IH stuff. I know it would be cheaper to buy Cat reman injectors which are completely new except for the housing (and it isn't unusual for this to be replaced which means a completely new nozzle), so wouldn't even consider this outfit to rebuild a Cat injector. Bottom line, the dealer might be a good choice if suitably equipped and experienced.

I can't figure why anbody would use anything BUT a brand new nozzle - unless it wasn't available anymore. New nozzle on a used holder is pretty much just as good as an entire new nozzle and holder assembly.

Bosch nozzles, brand new are sometimes as low as $5 apiece. Not the case though with low-demand stuff - like older farm tractors.

I just put 8 new Bosch nozzles in a GM diesel - and they were $4.75 each. Cheaper then some spark plugs.

On the other hand, I just put new nozzles in a 6610 Ford tractor and they were $35 each.

So- where do you buy nozzles? Also, I was told that the springs likely should be replaced.

Your comment surprises me, jd. The last thing I want is someone to put a new nozzle in my injector without cleaning the rest of it. Cleanliness is king when it comes to fuel injection components.

If your 806 is a 1963 it will most likely have the original style american bosch injection nozzle and they might just be a little more problem getting new tips for. Later ones had german bosch and there was a replacement tip made by german bosch for the american bosch. I don't usually replace springs unless they appear to have been overheated, for one thing the springs take a set and old springs are more likely to retain the pressure settings you arrive at when you repair them. You have to change shims to adjust pressure so one may have to disassemble more than once. Also, hope fully you don't twist off the alignment pins when taking them apart. Usually soak them in gunk for several hours to help avoid this. When these engines were newer I used to clean and adjust a lot of them, spending time examineing the tips, but later , just put in new tips,much less labor and then you have a good tip.

OK, and your comment surprises me. Cleanliness only counts on the inside. Means absolutely nothing on the outside.

Cleanliness is only a factor in the internals- and the rest is superfluous fluff. I'd say mechanical expertise is "king." The rest is salesman-ship.

If you like paying somebody $100 to $200 per hour to clean the outside of your injector holders and maybe paint them so they look like they're factory-fresh, that's your option.

I've worked auto/diesel repair shops where much times was spent sandblasting, anodized, painting, chemical dipping, glass beading, etc. so rebuilt products looked "like new" and therefore seemed more worth the high price.

To me, it's a waste of money - unless you're making a show tractor. Same with injection pumps. Bright shiny injection pumps dont run any better, or last any longer then the ones that just get a basic degreasing - before repair. In fact, sometimes the more drab looking ones are acually better inside.

Sounds like your got crow in your blood and think shiny things are best.

It take very little effort and time just to clean injector enough for repair.

You ought to be able to get any pump shop to order them for you. Best thing is to call around and find somebody that has them in stock. That because many nozzle #s have to be ordered in minimum quantities. Often in sets of 10. If someone doesn' stock them, they might insist you buy 10, or none.

Or do a web-search. For an 806, you need a DLL150S260 nozzle.

As to the springs? I never replace unless they are shiny on the side and show physical wear. Springs get shimmed or adjusted to make proper opening pressure, so a small amount of fatique is not a problem.

Generally would agree but have encountered at least two exceptions. Everything in a Cat pencil nozzle is replaced except the body and many of these are not reused. So if they don't have enought rebuildable bodies they just substitute completely new injectors although rebuilt ones are ordered. Quite a bit of savings with rebuilt over new and good chance you will get new ones anyway. Probably 15 years ago looked at purchasing new two cyl injectors for the 730D. New ones were over $800 each, so had mine rebuilt for approx $250. Don't know if you can still purchase new injectors from JD.

Early Deere 1010 and 2010 nozzles had/have the same problem. They were obsolete and unvailable when they were only 10 years old. So for them, the nozzles got pulled apart, cleaned, lapped, etc.

As far as new nozzles only - versus entire new injectors? Depends on price I guess. My comment was about choosing between - trying to fix old nozzles - versus installing new nozzles. Not about new nozzles verusus entire new injectors. If a person is paying for the work done - the money is better spent for parts - IF available at a reasonable price.

I've had chances go buy entire new injectors at times, cheaper then what just the nozzles cost. All depends on who has what, and wants to get rid of it.
