The tech there pointed out that the miss was not only in the 1000-1300 range if the engine was held at a steady speed, it periodically stumbled, no noticeable smoke in shop or parking lot, bobtailing down the road the white smoke would "boil out" of the pipes, for some reason more evident 1000-1300 RPM, maybe because this is my shift range, and I'm holding engine speed there.

C15 ACERT TIMING CALIBRATION CAT SIS INSTALL
Have not found the problem as of yet, mechanic that did the install went back over his work for a second time, then asked his #1 help to double check no problem found.īrought the truck over to local Cat shop, they hooked up the computer, did tests, everything appears OK. Should not affect anything, but due to the flaking, one exhaust rocker, and all six injector rockers were also replaced.Ĭan anybody help with this?.Thanks in advance. Mechanic is puzzled He stated that another truck had similar symptoms whenever cam was a tooth off, wondering if cam should have been installed at different setting, or maybe if overhead setting should be different from stock? Above and below this RPM, engine sounds, and runs fantastic, with no white smoke. Truck ran great in shop parking lot, however when I left bobtailing, the engine "stumbled" bad between 1000-1300 RPM, while throwing lots of whitish (fuel?) smoke out the exhaust. no experience installing an other than stock cam in an MBN motor which is stock except for a 550 flash, and 5232 inj. Very good wrench, however usually installs the identical part # that he removes (i.e. When I ordered the reman #130-9710 (800 HP marine for the 3406, and also used in the 700 HP military C18 I received instead a 10R7155, which I was told is a new cam instead of reman, (Do not know if the part # changed due to an update, or because of change from reman to new.)Ĭamshaft was installed by ex Cat tech, now independent, running his own shop. Had a shop replace the flaking camshaft of my '04 MBN C15.
