Dear Forum Professionals, Im an owner of a 1997 Freightliner FL70 with which needs new injectors. It is a Detroit 60 Series 11.1 liters. Im getting mix part numbers from the shop. Freightliner pull the VIN and reports part number R5234935 but shop is requesting part number R3405667 off the old injectors. Does these part cross reference to each other, and where do owners and operators get quality rebuilt injectors. Thanks Clampet
Is the aftermarket tune injectors a good thing and how do I cross reference the aftermarket injectors who do recommend for injectors
Do you know if that engine came in that truck when you are ordering injectors by vin # (truck serial number)? Detroit engine number is normally on a decal on the valve cover and the injector should be for that engine number. Then do you know that valve cover came on that engine? Is there a engine number some where else? Was the engine up rated to a higher HP and if you change numbers your backing up? Personally I would replace as removed, if it worked don"t change it (unless you really know everything and why you are changing it). Unless you are experienced with another supplier genuine Detroit only. Why are all of them being replaced? Shaker store can tell you X-reference.
not sure if this helps, but years ago I had 1 injector go down. took to my local freightliner dealer. told them to put a 6 pack in. 2 years later 1 of those injectors failed & started putting fuel in the oil. took to my local shop & he told me that all the inj that the dealer put in were for a 12.7 detroit, mine too is a 11.1 I asked is that a problem, he said no it does not hurt a thing cause he calibrated all inj to number stamped on it, i think. anyway, it seemed to me that more than 1 type of injector will work & work as it should.
Engine Number is Model No. 6067WU60. Check to see where the pulled it off the unit. Not sure on the engine originality, 3 injectors fire, 3 injectors wont. replacing all 6. fuel pump is working.
If you have two supply wires (computer) off the batteries and one has an open circuit it will run on three cylinders. The ground may work the same way. I believe every other cylinder in the firing order, 1 5 3 6 2 4. Easily noted by exhaust manifold heat at each cylinder outlet on cold start up. Touch each one briefly repeating intell cold cylinders are identified. If it is ever other cylinder I seriously doubt it is the injectors. I saw an ECM do that but only when under about 35 degrees and cleared up after a few minutes. Assumed it was some kind of cold start program but after a few years it started doing really strange things corrected by ECM replacement. It never ran on three cylinders again. There are some really sharp Detroit guru's on here sometimes if they choose to share and that's not me. Just my personal experience, hope that helps.
replace your injector harness even if you find the broken wire causing your problem.If it is original from 1997,it is due.good luck.
