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.

I think I'm comfortable with adjusting valves myself. A couple of questions:

What are symptoms to require an adjustment?

If "pinning" the engine is top, then rotate 180*, is there another hole to lock the gears in place at bottom?

Thanks

Mark the balancer @ TDC and BDC. Start @ the two front cylinders, bar the engine over until all 4 rockers are @ lash and balancer is @ TDC, exhaust .025 intake .015, turn 180 and carry on:

Link is to shop manual pages regarding lash adjustment sequence.

I'm getting ready to do the valve adjustment on my 3208T... almost 100K miles and no evidence that they have been done before. I have the manual and it shows a grainy picture with an arrow pointing at something to identify TDC, but I don't really get it.
I have the feeler gauges and some experience with similar projects on smaller motors so this doesn't seem ridiculous once I figure out how to know where TDC and BDC etc. are. I don't get the idea there is a pin on this motor/flywheel so it's a visual on... something?
I have new gaskets on the way and will try to get it right the first time.
Thanks for any hints you might have to offer!

What Randy said. If you don't "get it right", you will be buying an engine.

OK you talked me out of it. I remembered a friend who is a retired Snap-On rep who had mentioned a top notch truck repair shop. A couple of phone calls later, the FC is on their schedule for 3 weeks from now (they are busy!) with an estimate 2 hours at 97/hr to do it right the first time. Thanks Bill Pape for talking me down off another ledge! Now I have some time to work on other stuff. There is always other stuff!
