715 filter

What to do when story deadlines loom, Christmas decorations need putting up, and atricle installs lie fallow?  Waste time installing useless junk on the truck I drive the least, of course.


I've got about a million things that are more important to do, but I've been tripping over the dry air filter that came in the bed of my M715 for months.  I've stored it just inside my shed and anytime I go in for my trailer tie downs, oil, or some part I stub my toe on it or kick it into the leaf blower.  Today I finally got sick of it and decided to check it out.

It had been installed under hood long ago by Kaiser when it left the factory.  I'm guessing it was removed when the Chevy V8 conversion was performed.  It bolted in in a few minutes since it was all assembled and the mounting bolts had even been left in their bores.  It did hit the new radiator, though so I had to pull it back out and loosen the clamps that hold the filter canister to the mounts.  I was able to slide the whole assembly back enough to clear the radiator.  It's a pretty cool piece of equipment that I may or may not actually hook up.

Pull a pin and the filter canister drops down.  Loosen a wing nut and the filter cover pops off.  Loosen the filter bolt and the whole filter assembly comes out.  Mine is pretty scuzzy, but it says right on it you can clean it by soaking in water for 15 minutes and letting it air dry.  I'll give it a shot.  The fan blades don't actually spin.  They get the incoming air spinning to create a centrifuge that spins heavy dirt particulate to the sides of the canister.  This helps the paper filter from clogging too quickly.  There is also a provistion for hooking up the factory snorkel, which I have absolutely no use in the world for.

I also decided to tear into the driver door to see why the window wouldn't roll up.  Turns out the actuator slot snapped.  I'll grind, weld, and reinforce it once things settle down.
