Have a '49 LA 5328635(that will need one new sleeve (original bore 4-5/8). Just one is pitted somewhat. Anyone know of a source? Hoping to remain with original size for purposes of economy. Assume I will ring all and have valves done. Would it be prudent to remove a little from head surface to boost compression? If so, how much ? Notice that pistons rise at least 1/8 above deck at TDC, does anyone know if that is standard or does that indicate higher comp.pistons? Am new to this model.

Thanx in advance
Frank

Many people that post on this site have spare parts, you should get several responses on your sleeve. Those pistons are the high altitude (compression) ones. Is the tractor propane? Propane was not original equipment on 49s, but many were retro fitted. Check the parts (casting) number on your head. If it begins with a 5 or 6, it is a propane head and is already high compression, you would not want to mill it. The standard compression head is a 4447 (or close to that, I do not have parts book here). One of the guys that posts here has written before about which heads can be milled, maybe he will add better info.

Puzzled now...number on piston appears to 1188, or possibly 8811 since it could be read either way. Number on head doesn't match anything in my parts book either. Reads 9.24 35
Looks more like a casting date but that would be way off for a 1949 vintage machine. They are cast and appear to be inside a number box screwed to the top of the head. numbers are clear and nearly 1/2 in high. The period is also clearly cast.
