8V71 Air Filter CFM -- Had a great trip

[TomC]

With the price of an air filter element less than $100.00, and an engine overhaul around $15,000.00- PLEASE all- do NOT blow clean the filter elements.  Blowing them out creates small holes in the paper elements thus letting dirt directly into the engine.  Just don't wait that long to change the filter-do it more often then you think, and the engine and you will be happier.  Good Luck, TomC

I was told many years ago to not blow out filters, shake/bump them on the ground if you need to. New filters are not that expensive and like Tom said, it's a whole lot cheaper than a new engine. Blowing them out also distorts the protection and alignment.

I know that the oil bath filters better than paper.  I also know that the oil bath MUST be appropriately sized to the engine for the filter to trap all the dirt in the oil AND be nonrestrictive.  Oil bath restriction to air flow doesn't increase with the time it has been in service since last being serviced.  Is any of this stuff I "know" wrong?

But!  Is the proper oil bath a better flowing and less restrictive filter at the beginning of the filter life?  If the paper goes thru it's life span moving towards a more restrictive, time to replace, item and the OB never needs service due to restriction the OB has always seemed, to me,  to be superior except from a difficulty point of view.

Thanks,

Melbo,

To get back to your original question, how many CFM.....

According to Centriprecleaner.com, the 8V71 requires 875CFM, the 8V71T requires 1250 CFM. The L10 requires 594 CFM and the LTA10 requires 687 CFM

I would assume the 71 series Detroit requires more air because it is a 2 stroke and makes power on every stroke. The Cummins is a 4 stroke and makes power every other stroke.

Well guys I couldn't let this die about blowing out air filters some wrong info here about the subject.
I went back and read the owners manual on heavy equipment I have own over the years and Cat, John Deere and Bomag recommends you blow the air filter everyday at no more than 40lbs of air when working in dust.
Some of these filters cost over me over 250 bucks each and going with some of you guys recommendations that would have cost me 750 bucks a day for the Bomag as the were blown out 3 times a day sometimes  just food for thought    

good luck
