Scott there 7 micron rating for the primary on the engine it starts at 30 micron and goes down, same with the secondary they have 6 micron ratings and start at 12 microns and go down

 I run into the problem some times when NAPA here sells people the 5 micron filter for the secondary they last about 2 days Grin

At that time I wasn't running the oil, but I was prefiltering the oil with different filters but never purposefully installed small micron filters in the xoacj

The Skinner valve that actuates the fast idle operates two air cylinders - one locks the speed control lever and the other is on the left hand side of the governor (as you are facing it).  It is also the buffer screw.  When the air cylinder gets air it pushes a rod with a spring into play that pushes on the idle speed control inside the governor (the same one that the buffer spring very lightly assists to stabilize the idle) and adds the strength of the fast idle spring to the idle spring.  That is what gives you the fast idle.  You should not be able to see the air pressure gauge change when you click on fast idle, virtually no air is actually used (call it about a cubic inch of air to actuate both cylinders).  Trace the air line that goes to the air cylinder that locks the speed control lever - it should have a tee connection and one line will go to the skinner valve and one line will go to the fast idle cylinder on the governor.

This is all if you have the same fast idle setup on your MCI that I have on my MCI, of course...

If you go poking around with the fast idle cylinder remember that it is also the buffer screw and as such must be adjusted precisely and carefully.  Too far out, and your idle will not be stabilized.   Too far in and the engine can run away.

Scott-

I'm guessing you may have purposely bought filters with a smaller gap because you were running motor oil.

Waiting for a call back from Williams. Asked them what the part number was. Anyone know what the primary and secondary micron ratings are?

Adding to the thread; I have an intermitent high idle on my 871. Flip the switch and the piston pops out that keeps you from operating the throttle pedal. And the air pressure gauge starts to drop but the engine doesn't always hop up on high idle.

Is there an air cylinder reaching into the governor body that actually speeds up the idle? Maybe it's worn out and leaking and causing my intermitent symptom.

Did you check in the back J box?  Right is pin 6 Left if pin 7.

Michelin has a three part video series on wheel end safety.  It is definitely worth watching if you own a bus.

I believe when the springs are compressed to be able to move the vehicle they are by design a single system aren't they.  Pretty sure they leak off together also, now ive had bushes and cedars and even chunks of ice in the way at times what a pain. Other more normal things I recall are the dry s-cam bushings and even dry slack adjusters and as mentioned pins or some broken springs especially if on the lower front side that would seem to hang and cause a drag problem and not really drag a lot in a situation to feel a pull probably get hot though. So im still stuck on the big park spring broke and cocked preventing the rear diaphragm carrier to full return as it should.
