[SEL] bore and sleave an engine question

[Steve Gray]

Hi Ron -

  Been there, done that, happy with the results. My Jaeger had inhaled 
much of the dust created during it's cement mixer days, and both the 
bore and piston were very badly worn (there was more carbon than ring 
material in the grooves!) I had to take a cleaning cut on the bore in 
the mill before proceeding with the honing job. That left the piston 
better than .050" undersize at the closest fitting points. The piston 
was also very oval shaped. I had the piston metal sprayed and turned to 
a few thousandths of the bore and had a  new engine when I was done. 
After seeing the results, I put a spray torch on my list of tools to add 
to the shop! I currently have a crankshaft that needs the same 
treatment, but no one does that kind of work in this area. :-(

CYA

- Steve
