[AT] Hydraulic cylinder rebuild.

[Cecil Bearden]

  Depends on the price.  He rebuilt a couple of cylinders the same size 
last year on my digger truck.  I had one apart and purchased the seals 
locally and he took apart the other one and then assembled them.    The 
rods have some bad spots in the chrome rod where the boom must have hit 
a live wire.  I bought some Belzona steel repair to repair them, just 
have to get it done.  Local supplier swears by the stuff.  I have 
watched the youtube videos and just have a problem grinding on a chrome 
rod, but it is supposed to work....
