I did a compression test on the dozer about 3 weeks ago. It was not good, It had 200, 240, 70, 60. I posted this on FB and was suggested to put a little oil in the cylinder and retest the compression. I finally did that tonight and the compression didn't change.
I guess the next step is to pull the engine and tear it down. I think I'll finish the mower before I jump on that. Here are some pics of it.
Bringing it home
The hour meter shows 1635 hours. Here are the sprockets. I'm not a track expert, sprockets look sharp to me. Got to get it runniing before I worry about that. Track tensioners are also pretty tight.
