[AT] Hyd. Cylinder Rebuild

[HaliganBar at aol.com]

This is a plea for help from all you expert hydraulic technicians on the 
list. I recently acquired an Enerpac hand pump and a couple cylinders for the low 
low price of $0. One of the cylinders, a 12 ton model H-121, is leaking pretty 
good. So, I contacted the local Enerpac dealer and the rebuild kit is $33 and 
in stock. I downloaded the repair parts sheet from the web so, I was feeling 
pretty proud of myself....until I read the repair sheet.

The directions warn the cylinder stop, the piece that holds everything 
together, may be staked (whacked with a punch on the thread line) and that the stake 
marks must be removed prior to disassembly. Naturally, my cylinder is staked. 
How do I remove the stake marks so I can disassemble, rebuild and reassemble 
this thing without wrecking it? I was thinking of using a small burr in my 
Dremel tool but I don't want to goober up the threads. Any suggestions from the 
more knowledgeable members of the list?

When I reassemble this I plan on using Loctite rather than staking it. 
Ultimately, I'm hoping this will be a useful tool for removing and installing pins 
and bushings on the MF202 loader and hoe (requsite tractor reference).
