So, continuing on my 580C journey and I have 2 different cylinders on my loader. The left is 3" OD w/ a 1.5" rod and the right is a 3" OD with a 1.75" rod - not sure if this is an issue and not sure which one is correct.... I have found a replacement for a reasonable cost but, not sure I care ? Any advice? Just repack 'em and leave it, get the used one so they both match?

Any advice would be welcome.

The 1.5" rod is from the 580B, slightly weeker.
Will have sightly more down pressure then the 1.75" rod.
I have 2 brand new seal kits for the 1.5" I bought by accident if you want them.

They will have different travel speeds.
It may or may not make a difference. I have no idea if it will.

If I could get the 3" rod cyl at a reasonable price I would do it. If you are not lifting heavy, probably wouldn't make any diff.
