I think a big contributor to stuck filters is installing them without lubricating the seal and engine heat bakes the gasket to the block. Loosening them early, letting a little oil come out is one way to combat this.
That's my theory and I'm sticking to it...Never really thought about that. Makes sense, as it's pretty universal for end users to lube the gasket when installing a new filter.
Pretty sure they wouldn't at the factory.
Except the fasteners that need to be gorilla tight, like subframe mounts. Seems like they are always just past hand tight.That's my theory and I'm sticking to it...plus another beef I have with factory assembly is over tightening fasteners. The shop manual gives a spec on tightening a particular fastener and the factory installation is 2-3 times that spec, stretching threads and generally making removal a real PIA.
Interestingly enough, those are the bolts/nuts that the importer/dealer puts on the tractor as the loader mounts, wheels, ROPS and front axle (depending on the size) are installed by the importers/dealers.Except the fasteners that need to be gorilla tight, like subframe mounts.

Another Caveman......Take a long screwdriver and hammer it through the center of the filter, near the base, and get after turning it off!
I bought a tractor that never had the hydraulic oil changed, I had a bear of a time getting the filter off, nearly tore the filter housing off the tractor!
The screwdriver trick has worked every time for me and I've used it a lot..

Well if they don't get tight enough, I'll hammer it home with a big impactInterestingly enough, those are the bolts/nuts that the importer/dealer puts on the tractor as the loader mounts, wheels, ROPS and front axle (depending on the size) are installed by the importers/dealers.
I suspect they just send those bolts to the moon using impact guns, then end up stretching the threads and the bolts will never get good and tight again. Others probably just miss the bolts entirely.
