rings, sleeves

[kat]

ok,,,, i finally came to the conclusion that the rings let go in #1 cylinder
 comperssion test proved this,, 45lps, 109 lps.107 lps
now  is it possable to change the sleeve in just one cylinder? and re ring  just that one ?
 and is it possable to do it with out removing the engine?
or should i just go ahead and pull the whole thing out again and  redo everything?
 i'm asking because i'm kinda short on time.?

Anyway-  years ago my turbocharged IHC Scout swallowed some carburetor parts and scored a cylinder. Honed it out .010, stuck in an oversize piston; it ran 100,000 more miles, including 5,000 on the old Baja trail, with that one oversize slug. Wouldn't worry too much about doing that to a tractor.

It can be done in the tractor, but you might just have a bad valve. Did you do a air pressure test on the bad cly. to find out whats leaking?

ok what is an air pressure test.......soeey for my igronance.... but i'm  learning

[Bill Seal]

Aircraft types call it a differential compression test, racers call it a leakdown test. You apply air at a controlled rate through the spark plug hole and measure how much the drop is in each cylinder. You can buy the tester at J C Whitney for $67.99, called a cylinder leakage tester. If, as you say, it suddenly started fouling a plug and lost compression in that cylinder, it's probably broken ring.

The key thing is to take an old spark plug or purchase an adapter at an auto parts store that fits the spark plug thread. It is harder tro do on an L head engine as you need to have the piston at TDC compression stroke so both valves are closed. Lock it in gear and maybe block the tracks. Pump air in 40 -50 psi will do it and see if it leaks out the exhaust , the intake or out the dipstick .
