Can someone identify this engine and where to find repair info?

I thought I had taken pictures of the truck info, but I guess not, I swear my iPhone randomly deletes pictures these days

It is gasoline powered, the truck had a 10 ton capacity for highway service. I have no spark and I was looking for the best way to troubleshoot it. I know it has an ignition switch (and it was on), kind of a pain to mess with since the starter switch is on the floor. I thought maybe the TM for the truck would have info, but I am not sure what the model is.

Looks like a Continental R6602 engine, used in m39 series 5-tons from the early 50s to early 60s. M54 is the cargo truck, m52 is a tractor, m62 and m543 were wreckers.

It is definitely bigger than a 5 ton, has been made into a log loader, so no clue what it was originally. I will see what pops up with the engine model info.

I found a couple pictures of the truck from a while back. I can get the tag info tomorrow, was just hopeful I could get the TMs and look them over while it is dark.

It is a 5-ton bridge truck, m139 or m328.

OK, I will search the TMs, thanks for the info. We always thought it was a 10 ton version. What would be the difference?

I found the tag image, it was in my notes not in with my pictures, go figure. You were right on the money, downloaded some of the TMs to review, thanks!

I've been working on some R6602 engines lately myself and just got an early M-51 dump truck running was able to get some parts on eBay and got it running like a top
