[Farmall] "H" oil filter questions

[Robert L. Holtzer]

Time and heat are the likely culprits in hardening the gasket.  Even 
if the gasket is pretty hard, the cover will generally seat in my 
experience.  When the cover is tightened a bit, rotate it slightly in 
both directions to improve seating on the gasket.  Actually I would 
do this even with a new gasket.  A new gasket will probably last 
numerous oil changes -- but if a replacement comes with the filter 
each time, why not replace it?  Won't take much effort to replace.

With respect to changing the whole assembly -- why?  Granted it would 
be easier to replace a filter.  On the other hand, it wouldn't look 
'stock' if this is at all important to you.  The CaseIH or NAPA 
filters will do a fine job in the originally configured filter 
system.  Preferably with current detergent oils in my 
preference.  Castrol and Pennzoil are what I've used in my several 
tractors including Farmall.  I know that any number of owners are 
concerned about using detergent oil in old tractors that are a bit 
sludgey.  This has not been my experience but I have changed oil and 
filter within a few hours of changing to detergent.  Also have opened 
up the filters to see how much sludge may have accumulated -- haven't 
found much.  On the other hand if your engine is really sludgey 
(check under valve cover), I'd be cautious.  Farmall thermostats keep 
the engine at a decent operating temperature which should minimize 
sludge build up.

I'm reminded of the philosophical pearl:  "we give nothing more 
freely than our advice".  Happy tractoring!!
