Thanks for the reply Murphy,
I'm aware that all the things that you mentioned are what need to be looked at, was hoping that someone here had already blazed this trail. I have my engine out, bought a motor off ebay that was claimed to be excellent runner. I had it shipped to me and when I got it it would only turn about 250 degrees. Long story short with some PB blaster and patience I got the engine turning and mounted it into my tractor to see what the compression was and to try to start it. No go. rear cylinder has 50 psi center 175 didn't bother with the front at that point. The seller is very good and is taking motor back with full refund.
The original engine has a damaged sleeve in the center cylinder from a cracked head than sat for a long time with water in it. I had head rebuilt and cracks repaired but the head is still bad, I knew it was crap shoot going in. Anyway, I'm looking at all my options from getting new head and re sleeveing to reman to bigger runner or good used D950.
The 1105 I mentioned is to far away to do the exploration. Hopefully someone here has done a swap with an 1105 or 1005, and I may just bite the bullet and get the reman and be done with it. Thanks again.
Dan
