thanks edb, that diagram explains a lot, there sure isn't much that can go wrong with the compression release, the old timer must of backed the nuts off on the rods,
i'm not sure why he would of done that.
As far as the engine being tired and worn out I thought of that, but it just doesn't make sense why the old timer would of went through all the work to remove turbo, buy a new one, both new a old turbo's were there in shed, go through all the work to build blanking plates to cover all the flanges so no water or dirt could get in, and all the undercarriage is all new, to spend that kind of money on a machine with a worn out engine just don't make sense to me, (but who knows it could be).
As far as pictures you guys tell me how to post pic's and I will.
We won't be working on the old girl this weekend, as we got about 1 1/2 feet of snow and all the roads are closed some pretty crappy weather

Soumds to me like the compression release has been turned over.
Remove the split pin them the clevis pin from the compression release rod where it comes out of the engine at the rear of the engine. Rotate the shaft 180 degrees then re instal clevis pin and split pin.
Engine should start.

Well went to try cat again but no luck, changed oil in pony motor and put a different needle and seat, but couldn't get pony going, tried adjusting float and pony motor would not turn over,(seized)
So I have way bigger problems now will drain coolant and remove pony motor and see what happened in there.
Not sure if I should just put a starter in or not, does any one know how to heat head up without glow plugs,
I realize it will need glow plugs but don't want to do it in the bush, just want to get it going so I can get it home,
Let me know what you think

King of Obsolete I believe uses a torpedo heater and a tarp over his old crawlers,in what he calls the Great White North. He checks in here from time to time, but seems to have a lot of trouble with computers. But does have a site if you are not familiar with him,look him up. Because he has to be a heck of a mechanic if he can make tractors that rested under water for a year or 2 to run again.

Did you pull the plugs to see if it was just hydro locked? Possibly fuel in the cylinders stopped it from turning over. Weird it seized just like that. Unless something majorly bad happened hopefully you can get it freed up easily. Good luck

You could removed the startor and try turning the poney with a long screw driver by the flywell ring gear or by the hand crank

Hi guys,
I'm trying to upload some pic's of my cat, it is still not running, I pulled the seize pony motor, I think I have everything to put electric start on it.
I managed to find a starter from a d8h that had bin burnt, I got the starter rebuilt, I have all the heavy cable for it, ordered two new 8d batteries.
I still have to tap the holes for the starter, put the 2" frost plug in, I made a fitting for the cooling water that comes off of the heads, needs to be in stalled yet, this will be where I will plumb in the circulating heater for the coolant, for the time been i'm just going to install 2, 1/2"npt ball valves so I can fill it up with coolant.
I got the pre-combustion chambers from the burnt cat as well and they have glow-plugs, I want to install them when I get it home where I can make sure everything is good a clean,
I'm wondering if I put some heat where the exhaust of the pony motor went in (its the tube on the intake) if that will work to heat the air enough to get it going
I'm still a ways from turning it over though, me and the wife are going to go and work on it this weekend, if the yard where it is sitting is dried up enough, just won't stop snowing

Here is a couple pic's of the cooling lines from the burnt cat, this is what i'm going to do with mine, there is a pic of the 2" hole from the pony motor cooling line that I got to put a frost plug in, I forgot to say there is also a oil passage to the pony that I have to blank as well , does any one know what type of gasket material required where the coolant comes out of the two head (there is a pic of it), as you can see the holes are drilled where the starter goes, but the one thing I did not check are the holed drilled to the right size.
I also included a pic of the left side of the old girl with my little squire

What are your plans for the pony motor? If you have no use for it, offer it to someone here rather than the scrapper as there's always some that either need parts or an entire unit. Since yours was running, it's probably in fair shape at least.
