Probably should post this on the engines board but I think it will get more exposure here.
Mechanic friend of mine working on a Galion motor grader with a UB220 gas engine. Compression so low it wouldn't start, less than 50 psi on ALL cylinders. Took head off and found it had already been bored .060. No sleeves so block is junk unless customer wants to go to the expense of boring all6 and putting a repair sleeve in each hole and taking it back to standard bore. We can,t turn up standard pistons either.
What we have found so far is that the bore and stroke is the same as the C221 tractor engine but the rods and pistons are different, different compression height on the pistons. Appears to be a truck engine since is sleeveless and it also has the cross hole thru the block for the throttle linkage as on the old IH trucks. Original casting # was 2XXXXXR1 but has been ground off and 306750 stamped in its place.
Does anyone know what we really have here????????
Also, does anyone know if the bolt pattern on the back is the same as the C221, C263, D236, or D282 tractor engines????? I say it is but mechanic says no. Have found a running D282 we could put in if it will bolt in.
