Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
Were the engines of the same CPL number? Some parts do not interchange. WHat were the engine serial numbers of both engines. ?
Ok what is the Serial number of the one you put together to run? The engine that has the issue???
Do you have both serial numbers handy? Cranks and cams do not matter..
Pistons, turbos, heads injectors matter
Ok let me check
So you have a mishmosh of parts in this engine
CPL 835 -------------------------- CPL 1346
CAM--(###) ###-####-----------------CAM -3820013
CYLINDER KIT (Includes liners---3800801) PISTON Wrong for CPL 1346--- Piston(###) ###-####is correct and liner is the same for both engines
Wel The CPL is in place for a reason This is what the engine needs to perform to the fullest If there are changes to the hard parts than you will get a dud. well you have to pick a CPL and stick with it. The original esn should be stamped pn the block to the rear of the fuel pump side under the head . it may be hard to see clean it up with sand paper. Your injectors don't have check balls... . That came out with the ISX engine. gezz.
More like mismatched injectors to pistons and heads . even a cam with the wrong timing will cause your issue. Did the old engine have an offset key in the cam to advance or retard timing.., these are the things to concider..
The part number on the end of the cam towards the back . and the wold-ruff key should have a part number on it or grooved to the left or tight if offset
You cannot just put an Cummins engine with different parts they will not work together and cause severe engine damage. Use the ESN for CPL and ESN for the engine you want to build for correct parts .. Not the other..
ok just reply back to this post . O will be here
You have STC injectors forcing them down will cause them to fail. the tolerance is in the adjustment The injectors are mechanical and not supported by the fuel shut off solenoid. The solenoid has NOTHING TO DO WITH THE INJECTOR. The fuel shut off sel allows fuel from the pump to injector/ Are you a mechanic? If not have the unit taken to a Cummins shop..
The fuel shut off solenoid takes the fuel away from all injectors and shuts the engine down...AKA the FUEL SHUT OFF SOLENOID....,I think this is above your skills and need to take to a Cummins for repair
The injectors you installed are STC, All older engines are STC.
Step Timing Controlled. = STC
The service books are not printed any more. You are in the dark. unless you have a Cummins look at it. Before you get into a issue . I can only help so far without being there , But i see a of problems already
your trying to put two different engine r types together. it WILL NOT HAPPEN. Pick the CPL and ESN and rebuild it to that spec..... With the correct parts for that ESN/CPL
Try swapping injectors from #3 to like #5 and see if it follows. If so replace the injector. Then see what happens.
ok . Pleas e don't forget to rate my service.
