Bingo given the age of the plow he doesn’t know what to expect for the filter? It could also be damaged. If I were the guy I would clean the original one at least but I say replace it.
In fact for $75.00 usd I would buy the Storks rebuild kit and rebuild the all the gaskets and o rings. Let’s face it the unit is pushing 25 years. That is a long time for any gasket or o-ring.
It’s also just a suggestion not an invitation to an argument.
Again age of the filter is moot.
After he cleans it he can inspect it for any damage
Then replace it.
Why replace good parts with good parts?
I have a lot of hydraulic stuff that is well over 25 years old and I don’t go digging threw them to just replace o-rings, do you?
with all of your equipment or engines that are over 25 years old dew you Tare them apart and replace the gaskets and O-rings?
I’m just asking for a friend.
I’m not arguing with you I’m just pointing things out to the other guy where you may not be as correct as you think you are
Or That your suggestions are make work at best.
