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.

Default Caterpillar Valve adjustment specs

I have looked over my CAT books for Valve adjustment instructions. Found the numbers however I was unable to determine if the Valves are adjusted hot or cold. Anyone know?

i do it cold,if you do it hot,when you first start everything is hot,after an hour its all cooled off,so the adjustments are not the same.

Default Valve adjustment specs

Looked for a while to find this but no luck. While the doghouse is off getting new insulation it is time to adjust valves. What is the procedure-hot or cold, running or stopped? I gather from what MikeH said it is done not running. What is the dimension for intake and exhaust? Thanks in advance, Rick in Ohio

Since it requires a lock nut to hold the setting, doing it running would be one **** of an experience. Only kidding, the Perkins uses the same procedure, cold, not running.

Things are easier when you use factory trained experts. Example: after replacing our 3208 with a factory reman I took it in after the recommended 12,000 miles to have the valves adjusted. The shop foreman told me it could not be done without removing the engine and the company would not cover that cost. He added that it probably wasn't necessary, anyway.

A while back I had a mechanic who worked out of his truck doing some stuff for me. He adjusted the valves with no problem. As I remember it, it took an hour or so.

I think the foreman was under pressure from CAT and NC management because he admitted the engine they replaced which was a Ringhaver in Naples replacement had problems and did a warranty replacement. CAT warranties are good on the sixth Tuesday of the thirteenth month, only.

In my experience CAT stands behind their products...as far behind as they can get.
