Any set of jumper wires would work. However to do it right the one used for the exciter line should have a 10 ohm resistor in series with it. Emery Stora > > If Ken';s tests show the problem is still there, get a coulpe of these: > >...

The GMC originally came with a shallow well pressure switch. Check Amazon under that description. There are many. Here is one that should probably work but check the pressure on and pressure setting ability...

You can leave the drums on the rear axle and modify the cable to pull only on the rear drums. Or you can put Cadillac calipers in the rear with their parking brake setup in the caliper or you can putchase Lenzi’s hydraulic disc brake setup which adds a small caliper to his disk for a parking...

The latch mechanism is, as Billy says, a Kenworth but it takes a GM tumbler. Any good locksmith can assist you or you might check Applied GMC or other GMC shops. Emery Stora 77 Kingsley Frederick CO > On Tue, Sep 24, 2019 at 9:30 AM Billy Massey via Gmclist < > >> Tell em it's for a...

If the coil rusted then everything else in the engine would rust or corrode. It would be immersed in antifreeze and if they changed it every two years the coil would not rust. Emery Stora > > Interesting tidbit.. > I went to the local Napa today. They had a flex hose in the trash area. We...

The deteriorated insulation on the boost cable was not in a RECALL. It is mentioned in a DEALER SERVICE BULLETIN, NUMBER: 77-TM-4 GROUP: 12-Chassis Electrical-2 DATE June, 1977 The difference is that a Recall is mandated by the government and the dealer is to repair or replace it at GM’s...

Johnny You missed the point of my post. You had posted "most reliable was a 30KW Onan which had a 300 CID Ford truck motor running on natural gas with a propane backup system.” I was responding, tongue in cheek, to that sentence. I was asking if the 30KW Onan would fit into the Onan compartment...

Jeffery It is meant to run with the Onan closed in and the door closed. The design pulls the cooling air in and around the top of the Onan and ejects it at the bottom. It doesn’t cool as well when it is pulled out as the air doesn’t circulate properly. Emery Stora 77 Kingsley Frederick CO...

If you look at the Alcoa nut they say 45 lb-ft. The 150 was for the original steel wheels. Emery Stora 77 Kingsley Frederick CO > > While I am thinking about it, this past weekend when I dropped the fuel tanks I needed to pull one of the wheels to get to the air/liquid separator that was...

John Ethylene glycol alone is not a good lubricant but manufacturers of good antifreeze put in water pump lube, antifoam, rubber antiswell and corrosion inhibitors. If one changes the antifreeze every two years it really Isn’t necessary to add additional water pump lube. Emery Stora 77...

I had that problem one time so I got a piece of wood that would prop between the switch and the front of the seat. I moved the seat forward to keep pressure on the switch. You can also run a jumper wire from the positive of the battery to one side of the boost solenoid and it will keep the...

James, I have never seen a GMC that was not equipped with the self adjusting rear brakes. Has anyone else here ever seen that? Emery Stora 77 Kingsley Frederick CO > > Not all coaches were equipped with self adjusters. Nor were they all the > same when it came to those slots. Don't know, and...

Most people don’t back the GMC enough and also hard enough to adjust them. When I had drum brakes about once a month or two I used to find a large empty parking lot and get my GMC backing up at 10 mph or more and slam on the brakes. I would repeat this about 10 times and then my braking would...

I have to use them on my steering box because I cannot stop the drip from a line no matter how tight I make it. I even had a new line made (cost $65) and that didn’t help. Emery Stora > > I bought mine off the local Grainger store. They had to have them sent from the warehouse, none in stock...
