[AT] Oil Filter question

[Rob Wilson]

This is the same logic used by the Wix engineers and they
were wrong causing numerous A-C tractors to loose their
cranks. This as pointed out before has been hashed out 
dozens of times on the Unofficial Allis site. There are
quite a few A-C owners that now have excellent parts
tractors thanks to the Wix engineers. So unless you are
independently wealthy and own a pile of cranks stick 
with the C159 Fram filter.

Agreed, but experience on this particular project indicates that there
may be sufficient flow to deliver at least some oil even with the filter
wide open.  In this case the tractor was running without the little
vertical pipe; the filter wasn't even getting wet, and there was no
pressure registered at all on the gauge.  But I did have the valve cover
off at that time, adjusting the valve clearance.  There was a nice flow
of oil up that high on the engine.  And since it did have at least
several hours of operation, the mains were obviously getting
lubrication.  I had forgotten, or maybe never noticed, the cross-block
line Cecil mentions, I don't know if it that was running or not.

I'm still betting that with the pressure that remained with the new
style filter installed, the engine was getting plenty of lubrication
(albeit less than factory specified), especially considering the
evidence that it may have been getting sufficient lubrication even with
no filter resistance at all.
