Hydraulic Cylinder Rod Straightening

allenlane · Sep 26, 2020

A bit off topic, I managed to bend two hydraulic cylinder rods and the manufacturer wants an 2 arms for them. A fella on the interweb says he can straighten them to the 7 thou tolerence, and I found a shop that says he can do it. Anybody had any success with doing that?

I've straightened rods to within 0.001 using a hydraulic press, v-blocks,
aluminum sheet to prevent marring the chrome, a straight edge long enough to
match the length of the rod, and a dial indicator. If the shop says they can do
it, and they are trustworthy (or they can refer you to someone they have done
satisfactory work for) then it sounds like a good idea.

To close this one out fellas. I found a chopper shop that got my two rods to 3 thou for $50/each. Much better than $800 for each cylinder. I've put one back together and works like a champ.
