[Farmall] [Bulk (7.05) ] Re: Super C Problem

In "normal" operation, I wouldn't consider replacing the mesh.  As long as 
it is in good condition and can be cleaned, there is nothing wrong with it. 
If it deteriorates (main risk is rust) or gets to where it is impossible to 
clean, then consider replacing it.  I wouldn't consider either of those 
conditions to be normal.

Ben, I am not a mechanic and only found out about the steel wool from
postings on this list in past years.  My supposition that IH considered the
steel wool as an integral or "permanent" part of the air cleaner body comes
from looking at the parts lists and exploded diagrams.  I agree with your
ideas on working vs. show usage.  That 60 hour cleaning schedule would have
been for a tractor being used in dusty, dirty field operations.  Most of us
today just need to keep clean oil in the oil cup.  As far as the actual need
to take it apart, I wouldn't fix anything that ain't broke.  The air cleaner
is just another possibility to check if you are getting poor performance and
the recommended cleaning would be the first step.  As with your small
engines, a clogged air filter can cause what seems like fuel problems.

In "normal" operation of a tractor, how often should the air cleaner steel
wool material be replaced?  What justifies replacement versus a good
cleaning?

I'm thinking of "normal" as the average work tractor usage, since a restored
show tractor will most likely never be dusty/dirty enough to warrant
cleaning.  You mentioned that IH considered the steel wool a permanent part,
and in my owner's manual (for a c.1952 Super A) IH only recommends flushing
the air cleaner with kerosine every 60 hours.  I'm sure that things change
in 60 years, time may have taken its toll and the steel wool may need to be
replaced.

I did not replace my steel wool in the air filter of either of my two
tractors.  I did blow it out with very light pressure, from the carb side,
and wiped out the oil cup.  I didn't know the air filter came apart!

As a side note, I come from small engine paper air filters (depending on the
filter you have to replace them often) and foam pre-filters.  These filters
commonly fail, with the lack of adequate maintenance and replacement,
causing major engine issues and injuries.  I was surprised to find that old
tractors didn't use such disposable means; they chose more permanent
filters!  Perhaps that's part of why the engines last longer.
