how to shorten a hydraulic cylinder

[Harry c]

To shorten a welded cylinder, disassemble it and cut off the back end at the weld. This can be done with a Portaband etc. Cut the cylinder tube off the amount desired and re-weld. The back of the cylinder is not sensitive to alignment. Any work done on the seal end of the cylinder runs a risk of misaligning the cap and the bore. As the cylinder extends even a slight misalignment will quickly destroy the bushing and seal.

Reworking the back end is far easier and cheaper than recutting threads etc.

That makes good sense. Cutting the back end is less work if you have
a welded cylinder.

I choose tie-rod cylinders because they cost less and you don't have
to re-weld any ports as you do with a welded cylinder. The ports are in
the cast end caps.

if i were to "choose" cylinders i would just choose one that was the right size, but usualy they are used freebies so thats why im modifying them to fit.
