[Farmall] "H" oil filter questions

[Jim Becker]

1) Probably both.  Hardening comes from a combination of heat and age.  That 
gasket has probably been there for many years and through several oil 
changes.  It has been common practice to reuse the old gasket.  As long as 
the rubber still has some flex, it will reseal.

2) If you change the gasket with every oil/filter change, it will not get 
that hard and will be relatively easy to remove.  One stab with a pointed 
tool will get it started and the rest will peel out in one piece.

3) You are probably over thinking this.  I never looked for an adapter for 
an H, but have seen them on smaller letter series engines that use the same 
IH filter.  The question is whether there is an adapter that fits the H 
housing (which is shaped a bit differently).  I presume that any properly 
designed adapter would have to have a correctly sized flow restriction, 
sized for this engine, to keep all the oil flow from bypassing through the 
filter.  I wouldn't bother trying to change it.
