How to change injectors in a small cam Cummins. This procedure will work for most big cams that have non- top stop injectors.

I still run a 855 big cam great engines from cummins get a lot a flack from the young drivers but I get back at them when their newer engine is sitting along the road with a bad sensor thanks for the video Frank

Always a pleasure to watch you wrench! I learned the hard way bout the difference between top stop and base circle. Changed injectors in a v504 and was told they should be top stop like a 555, they weren't, I bent every injector rod on it.. stump, hammer and a dial indicator fixed em, but it cost me another day. Then there was the big cam 315 that was turned up to almost 400, but that's another story, lol. Stay safe and sharp my friend!!!!!!!

I recently got two trucks with big cam Cummins 3 one is a cpl 531 350 and the other is a cpl625 400 there in actually really nice trucks and I plan on working on the and running them! I decided to go with old instead of new! I do have a nice 99 pete but I’m sure they will get the job done! Great video thanks!

I got a question, i have a cummins nhc 250, 855 and it won't idle under 1300, at start up it will idle at 600 for 20 seconds, then jumps up to 1300rpms and stays thier. I adjusted idle at pt pump, I've turned down 3 times, and each time idle at 600 then jump up, adjusted again, idle at 500 then jump up on its own, adjusted again, idle at 500 and jump up to 1300 rpms, i can shut truck off, start up and idle at 600, then 20 seconds it jumps up to 1300 on its own and stay right thier. I'm not sure, it don't act like getting air, because don't stumble at all, everytime I start it, it starts right up, no hesitation.
@Digginok10 ай бұрын
I’d try to rule out an air leak first, could be hose, filter, throttle shaft and pump shaft seal. It doesn’t take much air in the injection lines to cause a spongy throttle. I guess it’s possible the governor is acting up too.
@staym92510 ай бұрын
@Digginok I figured it out, the button was sticking, had light coat of rust on it from sitting for 15 years, I pulled apart, cleaned up the button, springs, button holder and governor screw, put back together and idles and runs great.

Can you please provide a part number for the injectors that you used? I am wondering if its better/cost effective to pull my injectors and get them reflowed or ones like yours. I have an NTC350 small cam in a 77 White-Freightliner. Its a hard start when cold and smokes like the dickens. But runs clean and clear when warm! Even under load! Apparently someone rebuilt it before me.
@Digginok2 жыл бұрын
Don’t have the part number, but even. If I did I’d recommend calling premco diesel service. They are very knowledgeable and reasonable on the price. A small cam will always be tough to start cold.

@Digginok2 жыл бұрын
There are two different procedures, please study this before you make the mistakes I have made. I am using the torque method with non top stop injectors, aka outer base circle. If you use inner base circle with dial indicator you will set valves on 5 and injector on 3.
