Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

You need to pull the pump and get it freshened up. Levers stuck isn't a quick and dirty fix, think runaway. That would be bad. If the fuel is strange, seized stepper pumps would explain the stuck rack. Not a place to get forceful, lost of little pricey parts in there. MMO might help, pb or similar, maybe, wouldn't bet on it.

Default Good Idea!

I forgot about that stuff. I used to fix a lot of carburetors and sticky lifters with Marvel Mystery Oil!

Default What is pb?

Mike, I overhauled the Perkins and have worked on some tractor engines, but the cat manual makes removing and timing the injector pump a little daunting. Do you think I would be in over my head?

Not difficult, don't forget to remove the long 5/16 18 bolt before firing up the engine, realistically the balancer mark and pointer coincide with the threaded bore in the timing gear appearing in the access hole. Verify the threaded bore in aligned with the hole, line up the balancer mark with the pointer, good enough, don't really need to thread a bolt in there. Bright light, you can see it pretty easily. Engine is turned manually of course, no starter bumping. Unfortunately I'm out west, don't have any NA pumps on the shelf @ the shop in WI.

I just removed and re-installed my injection pump, not difficult. In fact Randy assured me that it was well within my skill set and he was right

Mike,
Since you said you do not NA pumps on the shelf do you normally rebuild, or freshen up the injector pumps?

Hope that works out well for you. I just kinda didn’t like shipping something like that.

Got back on line this afternoon, traveling. We do turbo and NA, run them on a test engine after rebuild to verify calibration and rpm. However, don't forget that the cylinder head adapters, the dealies that connect the injection lines to the nozzles under the valve covers need to be checked for blockage if the engine is missing. Blocked adapter will cause a dead cylinder.
If interested in injector pump work, please PM to my email address: mhohnstein@wi.rr.com
