That sounds right and makes sense, but I don't know for sure if this will accomplish what you want. I do know that if a vehicle comes in with a hard start, white smoke complaint, after checking some other stuff, verifying the engine to pump timing is done. I have seen pump timing off just enough...

From a Cummins POV, there is no other timing adjustment other than pinning the engine at tdc, pinning the pump and stabbing it. Any other "mod", anything other than the pump internal timing as per Bosch/Cummins spec and the pinning of the engine is all that is published. Nothing to change timing...

That procedure is spill port timing. That is used only to ts a performance issue...white black smoke, low power. I can tell you in almost 30 years, it has never had to be used, in my shops atleast, it is a grasping at straws thing. You just need to verify your pressures, If they are there, the...

A stoopid question, did you try stepping on the gas while cranking? Shouldn't need to, but if the delivery valve rod and stop magnet have joblocked, this could also be a possibility. Joblocking is when two flat, smooth surfaces get stuck together by a liquid....like cold, thick oil. It is a...

I forget what gov these have on them. If you want to see if the pump is turning, there is a cap on the side of the gov housing that contains the timing pin. Take the plug and pin out and crank it while looking in the hole with a mirror. It is the plug that you time the pump to engine with IF it...

If a bearing has spun, the crank is junk. The smoke you are looking for will be coming from the blow-by tube, not the stack. Replacing a crank in frame is more work than pulling the engine. the complete engine needs to be suspended in place, trans, flywheel housing and the complete front end...

could be a failed overflow valve. can you remove the return line from the pump to see if fuel is just flowing out and back to the tank? It should normally be under 20-30 psi and spray out of the fitting.

All that needs to be done is plumb from either suction or pressurized coolant flow, (to the inlet of the w/p or to someplace below the head/block joint) to a place somewhere above the deck ( head/block joint).

It is a bearing or bushing. The engine sounds good, so a rod should ruled out. it could be a main bearing, after it warms up, look for heavy smoke out the breather, it will smell burnt. Sometimes an 855 will run with a spun main and have no noise. It could also be an accessory drive bushing or a...

Cummins/Bosch part. Give me an esn and i'll see if I can find a p/n. I have never found a torque for one of the plugs, but, the return line banjos torque to 18 IN LB. Again, a bosch inline pump is self bleeding, no need to crack any lines or fittings.

ESN should stamped on the block. Fuel pump side, rear, at the area where the heads meet the block. Post it and I can post the build info

Any popping in the intake or chuffing in the exhaust pipe? A diesel only needs 4 things to lite, rpm, air fuel and compression. Look at those things

Common issue for hot, high volume return systems, not an issue for the Cummins in the military iron.

Instead of piggybacking an OLD thread that has nada to do with your issue, maybe start a new one with your question. You are more likely to get some responses in regards to your issue that way.

Any low silicate coolant will be gtg. Stay away from ELC, extended life coolants, the red and orange stuff, Dexcool and the likes, they attack rubber that is in contact with coolant. Fleetguard coolants mix with all other coolants so you won't get that black goo in the system if you don't get...

Dunno, there were 100's of thousands of mechanical C's made, still making them for non lead emissions areas of the world. One would need to find a book for the C8.3M version. If you install the head from an M version on an on road of construction type of engine, you will have smoke and power...

Heads, cooling system, fuel system and exhaust. 400 hp rated C series are mainly found in rec vehicles. They were pushing 500 out of the mechanical C for marine in recreational apps. Automotive was rated at 325 max for trucking. Hey Bandit, can you tell me why Cummins went from that small, like...

Made many of the fittings, not hard.

^^ This is correct. The lift pump is capable of upwards of 70 psi and it does can have serious pulsation. It is better to install the sensor/test fitting after the filter. This will tell you when you have a filter issue.
