How often do you guys clean your pre-filters? Last night was my 2nd time. I put about 3000 miles on my last Donaldson so when it finally went I didn't think twice about putting another one on the truck. Then the next filter only lasted 100 miles with limited success. I would lose pressure under any load other than cruising. Cleaned pre-filter and left the Donaldson on it just in case that was the problem. The pre-filter was kind of dirty... maybe 10-15% of it had gunk on it. Still no luck. Then I swapped Donaldsons and the system is back to perfect.
Are you guys checking your pre-filters often?
Other than compressed air, what other methods are you using to clean it so that it maintains its shape?
Mine was kind of bent so I hammered it round around a piece of pipe I had lying around.
Another though I had while I was under my truck in a foot of snow... as the slush and salt was falling into my face I was struggling to get the allen wrench into the hole and then get a good grip on it to remove the filter.
It got me thinking about building a hinge into the guard I'm going to build.
Pull a pin and have the unit hinge down from between the frame and body so that everything points down. This would help keep oil from covering the entire manifold when you're servicing it, as well as make accessing the pre-filter easier (much easier).
Thoughts?
