[AT] John Deere Head Lead Washers

[John Hall]

I was thinking a seal as well. Long time ago the SEL guys taught me to 
use a solder to make a seal for head bolts where the bolt cavity was in 
the water jacket.

There was a discussion on the list here on how to get a engine unstuck. What I saw after I got the head off I would never run a engine after it was stuck without cleaning the cylinders. I pulled handfuls of crap out of them, and this tractor had not been stuck all that long.

>>       One thing I can laugh at now. When I installed one of the pistons in I puched it too far and the oil ring came out of the cylinder. I am lucky that I have small hands and could get a ring compressor on it and push it forward. Very small space and and awkward angle.
