Hi everyone,
I finally got the tractor running right.
https://www.youtube.com/watch?v=U9weTVwVqoM&sns=em
I know I have low compression in cylinder 3. I did a dry test before the winter and that showed:
Cylinder 1 - 132 PSI
Cylinder 2 - 126 PSI
Cylinder 3 - 110 PSI
Cylinder 4 - 130 PSI
Doing a wet test on cylinder 3 got it to come up to 125 PSI.
Now, when the tractor is running, there is a lot of exhaust gas coming out of the oil fill cap on the top of the tractor. I am certain this is blowby past the rings from #3. I am wondering, is it impossible to replace the piston rings without pulling the engine?
If it is possible, my plan would be:
1. Rotate engine until #3 is at TDC
2. Drop the pan
3. Pull the head
4. Tap the piston out, see if it only needs rings, or a new piston, sleeve
5. Reassemble
I am wondering if this process is possible, or if the engine needs to be pulled to have any chance of getting the #3 piston out. If the engine needs to be pulled in order to replace them, I am probably going to ride it out until the engine needs a full rebuild, or let the next owner take care of it.
Thank you!
