[AT] Oil Filter question

[Bill Brueck]

I have a friend with an Allis WC who inadvertently threw away the little
center pipe once when changing oil filters.  Of course the tractor did not
show oil pressure after that.  Much to my dismay, he used the tractor
(lightly, just a retired guy with a few acres, I don't think he plowed with
it or anything) for a year that way!  I finally convinced him to bring it
over so I could check it for him, I found the pipe missing and made one for
him out of a brake line.  Pressure restored.

So point being I expect the engine was getting oil all along anyway.

Will be interested in other posting about this, I've wondered what was
happening with Jerry's WC that year.

Subject: [AT] Oil Filter question

Older Allis Chalmers, Case and maybe some other tractors use a rag filled
oil filter that is presure fed into the filter media via a small tube that 
extends up into the filter.   I just bought  2 filters yesterday that are 
WIX brand (good filters) but they are no longer rag filled.
Now they have a rubber bladder inside that the oil tube goes up into. 
Around the bladder their is an air space and then some filter media around
the perimeter of the filter canister.

It looks like a good design but unfortunately my D-14 won't build proper oil

presure with this filter.   AC used the rag filter to "regulate" oil presure

by restricting the flow through the filter media.
I assume that this new filter design is made to do the same thing but it 
doesn't seem to work.   With the old rag filter my oil presure guage moves 
the needle to about the middle of the guage.  With the new filter it barely
moves off the low presure peg.

I checked the WIX web site and they show this filter #51101 as the proper
filter for my tractor however they show it as obsolete and say it is
replaced by #57011 ( I think that is the number).  Does anyone one have
experience with this new design or information about the filter change,
etc.?

Everyone around here is out of stock on these filters.  Both the local NAPA
stores show it as back ordered from their distribution center.  I had to
drive 35 miles one way to get this filter and I bought 2 at $12.99 each.  I
need to run the tractor.  I guess I'll just  put the old one back on.

Thanks

Charlie
