    Nothing, it just clicked. I headed to Kenworth to get a new starter.

    I was undecided if I go OEM or Delco Remy, but based on what I’ve read and a mechanic suggestion to go OEM, that’s what im going to grab.

    Although it is a bit more $$.

    Have you guys ever used Delco Remy?

    Or do you buy OEM? (Paccar for my truck).

    I used to rebuild heavy starters and alternators for all those trucks.

    The Delco 40MT was the most popular.

    1114896, I think it was an 11-tooth CW rotation, 12V.

    They have a 42MT now, little more compact.

    I've done them all, including alternators: Magnetti Marelli, Paris Rhone, Leece Neville, Prestolite, and Motorola.

    I had a pal who had a 2001 Freight (((Shaker)))) also with the ISX Cummins, and he bought a brand new Delco 40MT starter and a Delco 25SI alternator to have in his sleeper.

    I think the one on the truck was possibly a Delco Remy, but it had no markings or even a part number.

    It was also slightly different than the OEM Paccar they use in the ISX Cummins for my Kenworth.

    I was tempted to get the Delco as it was $150 cheaper at Fleet Pride, but since I still have a warranty on the motor and components, I didn't want to give them a reason to blame a "non-OEM part" if something failed.

    Either way, I got it swapped out.

    Took me about 4 hours.

    About 1hr to 1.5hr was spent getting the bolt off closest to the block.

    Eventually, I figured out the best way to get extensions and sockets onto it to remove it.
