Air Governor

For those of you that have never changed out an air governor, here are a few pictures:

To adjust your pressure, under the rubber cap is the adjusting screw

Installation complete

Some governors are remote mounted, but mine is directly bolted to the compressor. The governors are cheap, this rebuilt unit was 16.00. I got mine at Fleet, but most truckstops and parts places have them. There are different types and pressures, just make sure your part number is the same. I changed it as a PM item while chasing an aux air leak. This took about a half hour, mostly because you have to R & R your fittings as the governor does not come with fittings, only plugs that need installed in the unused ports.

Even Jeep could do this!

And I thought we had to wait until next November to change out our air Governor. Governor Good Hair (Texas) should be scared.

Thanks to everyone. I will change out the governor prior to my next trip.

If you find a replacement that will begin to pump air when the pressure drops to 115 like the current one originally did I would be interested in that information.

All I have ever come in contact with drop down to 100 before starting to build up air again.

The only options at Bendix are as follows:

282436 100/120
284358 105/125

These are both high temp governors.

How did you get to the compressor? With it on the back of the 8V92, I had to either be in a pit or on a lift to even see the back of it much less get at the governor.

Hello Jerry,

I can reach mine from the passenger side door to the engine compartment. It is tight since I have OTR air. I have not changed it yet since I am working in NJ this week. But, I did get to it to make sure I could do the replacement job. The air compressor sits just ahead (toward the front of the bus) of the alternator. To change the compressor the alternator has to be removed, but not true for the governor.

Jdub,

This was from my CC series 60 numb nuts!
