[Patrick McVeigh]

im working on extend cylinder. i removed the wire that holds the cap into the cylinder. i cant get the cap off for shit. it rotates 360 degrees and it moves but wont come off. i tried to used engine hoist and snapped the chain.   i cant believe how much trouble im having here.

Is it an aluminum gland? Better off to get a new cylinder😘

[Patrick McVeigh]

yes aluminum. truck is old not wanting to put alot of cash in it. the hydraulic pressure must have pushed the retaining ring into the cap mushrooming it out a bit.

use hydraulic pressure to pop gland and have a machine shop make a  steel one
