Yeah, I see where the replacement is called metal, yet the old one appears to be fiber........perhaps they switched to a different matl?? Fiber would seem more forgiving & less apt to score what it is riding against??
Well I guess it ought to ride against the chrome of the rod, with X thousandths of clearance for an oil film of course. There is nothing I can see in the way of updates showing the replacement of a fibre bush with a metal bearing. The metal bearing has been there since Day Dot as far as I can tell.
You've piqued my curiousity now. Do you have a Part Number for the Cylinder Assembly.? If not the machine S/No will work.
The other explanation might well be that someone in the past resealed the cylinder using a non-OEM seal kit containing a fibre bush in place of the metal ring.
Lots of thing can be done "good enough" when getting a machine running again. Those cylinders have to be "done right."
And that's why dealers have cylinder benches in their hydraulics shop, to "do it right". Like John I've seen a fair few f**ked cylinder, control valves, and systems full of sparklies in my time as a result of people who either didn't know any better or couldn't care less using shade tree methods in an attempt to tighten those nuts.
As a suggestion put a good dollop of Loctite on it when you reassemble everything, just in case. (Original spec does not call for thread lock)
