Re: 66 C50 Cummins build aka Big Stupid
Took a few minutes to tear down the front of the Cummins engine to check on the “killer dowl pin” that they use during assembly to align the front gear cover to the engine block. The dowl pin can come out and fall into the gear drive and ruin the whole motor. I found mine had backed out about 3/8” so it was well on its way to destruction. I knocked it back in and made a hold down tab for it so it won’t be an issue in the future.
