Rob Posted July 31, 2008 Share Posted July 31, 2008 Tonight I had to fire up ole "Trusty Rusty" the 64 B-61 for a little tug on a trailer. As is the norm, he started right up idled smooth and started to build air pressure just fine. With about 80psi in the tanks I proceeded to hook up to the trailer and upon reentering the cab I noticed the air pressure was well over 150 psi. I quickly stepped on the service brakes several times to bring the pressure down quickly but this thing just kept a pumping and right up to 150 psi again.I know the air governor has prolly gone "belly up" but it is not the normal D-2 style that I'm acclimated with. This one says Sealco on it and looks different. Can I replace this one with a Bendix style, or should I stay with this type, (assuming it is still available), or look for a rebuild kit?Hopefully the photo will show up.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Mike Posted July 31, 2008 Share Posted July 31, 2008 Hey Rob,I'm just curious, is there suppose to be a hose connected to the right side of this governor. Also looks like this unit can be taken apart for repair, from my view. It reminds me of just a simple diaphram. mike Quote Link to comment Share on other sites More sharing options...

Also looks like this unit can be taken apart for repair, from my view. It reminds me of just a simple diaphram. mikeThere is no hose connection on the rt. side. That is a threaded adjustment bolt for pressure I'm certain. Like Glenn states, replace with a D-2 so that's what I'm going to do. I assume the diaphragm has ruptured or torn causing the problem.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Rob Posted July 31, 2008 Author Share Posted July 31, 2008 Replace with a D2 bendix.Kinda figgered that Glenn. I've never seen too much Sealco parts around but my experience is limited.Thanks again,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Superdog Posted July 31, 2008 Share Posted July 31, 2008 Sounds like you better put a new "pop off" valve on your air tank,too.It shouldn't have built that much pressure. Quote Link to comment Share on other sites More sharing options...
Rob Posted July 31, 2008 Author Share Posted July 31, 2008 Sounds like you better put a new "pop off" valve on your air tank,too.It shouldn't have built that much pressure.It has what appears to be a normal home air compressor relief valve on the wet tank and does blow at 155 psi measured. It is stamped at 150 psi on the body. Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

ThaddeusW Posted August 1, 2008 Share Posted August 1, 2008 Time to re-elect a new governor Rob . D2 is just fine, 2 ports needed. one from the air tank and then one to the unloader port. plug the air dryer port if you don't have an air dryer.

I ordered one this afternoon as per everyones advice. I don't have an air dryer on that truck so it should be pretty straight forward.Thanks,Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

The guy is a well known crook that is as bad as his predecessor. Ryan is proof that you can only piss so many people off till it catches up with you. Blagos' time is comming.I received the new air governor today but did not install it.

I just noticed you got quite a few listed...if I had that many trucks, I wouldn't have to jerry-rig up various "fixes" to get me down the road 'til I can make it by a place to get the "proper" parts.......the latest is a reverse sensor on the trans...gotta run a hot wire to the backup alarm from a switch in the dash so I don't get kicked out of the mines or written a ticket by MSHA Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!
