6CTA Air Filters – 2 part question

[Dave Lincon]

Looking to either service or replace my air filters… SN 46309849

SBMar store states S&B Air Filters DO NOT replace Walker Air-Sep filter elements.

I don’t know what a Walker Air Sep filter is.  Current one has a metal end cap and some holder springs.. 

 

Second part – I highly doubt the air filter has ever been changed in the life of the boat.  How much of a service item is this really for people?  Is this a regular service item?  What indications would exist if it were clogged / dirty?

The Walker Air Sep is intended to separate the oily vapour ejected from the crankcase from the actual air flow so the oil can be discarded without fouling the air filters s0  quickly.

 

Seaboards’  crankcase venting is another way to do the same thing.    Look it up.

I buy the K and N cleaning kit at Autozone. A degreaser, hose it off, oil it. I clean every 2 years.

Probably too expense, i.e. there are cheaper alternatives but I have Walker Airseps and just buy their blue cleaning kit.  Lasts a few cleanings/oilings.

What are you using for oil ?

I’m going to clean the big airsep filter on the QSB in a few weeks.

Do you buy the Racor cleaner kit ? Or ?

 

Thanks, Bill D

You just spray them with degreaser, let sit a bit, hose them off, let dry and re-oil.

It’s more like you clean them, no need to replace…is what I think that “do not replace” statement means.

If memory serves, they say clean every 300 hours but hold them up to the sun, if you can see through easily, likely ok but I do every year regardless which is a lot less than 300 hours.
