would suggest strongly that you use silicone grease as not all O rings are
nitrile and there can be a chemical reaction between petroleum based products
and some rubber compounds (also, speaking from experience

only compress. one problem I did notice was if you put too much grease in a
track for the oring it can blow out the ring while it compresses. I wonder if
oil or soap is a better solution. the hard part about placing orings is when
they are to be prefitted around a shaft and it is hard to tell that you did not
twist them while passing over threads of the shaft. twisting them distorts the
rubber and will cause the ring to fail (I have learned)

is to reduce the damage to the threads from over tightening. I have a Mustang
skidsteer that is under warranty contract and serviced by the dealer on site.
The tech recently replaced the two hydrolic filters which were also mounted on
alumnium. Without explanation the tech directed me to only tighten the filters
to stop any chance for leaking and draw a reference line on the filter to the
mounting base. one filter is the return and one under pressure. both are one
piece throw away.

is no bypass and when they clog they will strain the engin rpm. On a tractor the
pump is a major % of the HP consumed and strain is a clue. On a minor hp
consumable charge pump it will take out the pump. On some of the old stuff I buy
I have noticed this filter shade tree installed after market and I always just
remove them. They are often installed after a system failure when an unserviced
hydraulic filter plugged and fluid went bypass crapping out all the hydraulic
appliances. Problem with this filter on a small charge pump like the fan or a
dumptruck liftram pump is the HP to run is minimal compared to engine output and
operator has no clue of an issue. the fluid sits in the running pump and heats
up untill it cooks the

good. many of the mounting bases for filters are unique to the application. It
is best to look for the trajectory of the filter prior to removal to see the
angle. when they are way off angle it is easy to notice and refit. When they are
only slightly off assumed angle is when you end up fumbling and in danger of
cross threading (I have learned).

hints. Tom Sorrentino and I decided to do the job yesterday to see how it all
went together and learn what we could. For those of you who have the mid-80's PT
chassis and Hydraulic fan setup, the filter gasket that we're talking about sits
in a valley, just above the threads, on the top of the long, spin-on bowl that
is mounted to the frame near the fan. The bowl is/was made by Parker Filtration.
Tom has an '87 with an 8V92 and I have an '85 with a 6V92. Aside from being in
different locations, the bowl and filter assemblies were identical. Tom's is
located in the tag axle wheel well- Mine was located behind the fan motor and a
little higher up on the frame rail. The filter bowl is made of an aluminum alloy
and has fine threads that could easily be damaged if you aren't careful when you
re-attach the filter bowl. The O-Ring on mine appeared to be original. Tom's was
changed by a
> > PO in 1997. Both o-rings were in decent shape and we re-used them. I'm going
to get new ones from Bluebird of Pittsburgh. They had 3 new o-rings on the
shelf. When they arrive, I will take one to a hydraulic shop in Harrisburg and
see if they can match it up in the Parker-Hannifin catalog. When I get some
cross-reference numbers, I'll post them here and on the other Wanderlodge sites.
