[AT] Oil Filter question

[Rob Wilson]

Agco dropped the new style filter and recalled all of them
because of this problem. They now carry the new redesigned
(again) filter with what appears to be polyester fiber in
it and they work fine. As for cross bred deers you never
know what type of monster you would have gotten. That is
as long as them little deers didn't die from the shear 
size of the AC offspring :) VBG Okay back to generic 
tractor talk :)

Sounds like different and conflicting experiences folks have had.  Got
my attention about the apparently common experience of scoring
crankshafts.  

My experience is very limited, quantity 1 of a late model WC that my
friend had in my shop most of a winter while I helped him overhaul it.
That's the one that ran for a season with no riser tube into the filter.
I'm a Deere guy, was scared to death the Allis would jump the fence
during the winter and mess with my thoroughbred Deeres.  Didn't know
what kind of mongrel I'd have in the shed come spring.

So I guess our mileage really does vary, doesn't it.

Good discussion.

Confusion is a higher state of knowledge than ignorance.

I'm with Bill on this one.  My VAC Case works just fine with the new
style filters. It makes just as big a mess while adjusting valve
clearance with the pleated type as it made with the old rag filters, so
I'm confident that there's plenty of oil moving through the galleries.
I've seen two VAC's that were missing the riser tube from the filter
housing, which essentially results in total bypass of the filter -
neither one of them had experienced any lubrication related engine
failure.  The Case feeds the oil pressure gauge from a hole tapped in
the crankcase at the center main bearing and there's no noticable
difference in pressure between the two filter types.  I actually prefer
the new style filter - the oil stays much cleaner between changes than
it did with the rag filters.

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.
