I think that fuel economy requirements only affected automobiles. The GMC was considered a truck under the regulations. The EPA and fuel prices were not much of a problem either. Emery Stora > > Lets not forget the increased fuel economy requirements, the EPA and high fuel prices all leading...

I have read several posts about tinting windshields. Windshields are laminated glass. The plastic used in between the glass filters out UV rays. You can drive all day into the sun behind a windshield and your face will not get sunburned. The same cannot be said for the tempered glass at the...

Be sure to check if he fitting is tapered pipe thread or a straight machine thread. They are the same diameter and same threads per inch. People often put one or the other into a mismatched thread and it will cause jamming or leaks. Emery Stora 77 Kingsley Frederick, CO > > I am heading out...

James That is all very correct. I have also found that some have tightened the bolts (or nut on studs) too tightly and that can deform the gaskets and actually cause leaks. Emery Stora 77 Kingsley Frederick, CO > > Good job Emery. While you had the tin and flywheel off, I hope you replaced >...

It makes a big difference. GM had recommended .080 because of some problems they were having with misfiring. But .080 will burn up you module quicker. Nowadays we use .038 - .040. Emery Stora 77 Kingsley Frederick, CO > > i’ve got some Bosch Platinums that look kinda burnt, last changed about...

Here is what Dick Paterson told me way back in 2012. The spark plug issue was that AC DELCO changed suppliers for their spark plugs and the Rapidfire #7 'platinum ' plug was still made but was no longer a 'needle point' style similar to a Bosch -it now comes as a regular plug configuration in...

The Original front seal behind the flywheel is an Onan 509-0040. (The rear seal is an Onan 509-0041). The 509-0040 crosses to a National 470162R or SKF11806. Those are a single lip Viton seal. I found a double lipped seal that should be much better than the original single lip. It is made of...

Your bag is not just rubber. It has layers of fabric in it. My old bags and my new old stock bags both had about 80 to 90 psi at proper ride height Emery Stora > > What's a typical pressure reading at the appropriate ride height? I'm seeing about 80psi, seems high for a 40 year old rubber...

You cannot. Voltage and frequency are directly related to RPM. I adjust my voltage to 128 v at no load. This gives me about 120 v with an aircontioner and mucrowave both running. Emery Stora > > I just used this to tinker with my onan. at 63 hz, i'm 134v. How do you > reduce voltage, yet...

No, GM did not have a recall on this. However they did put out a service bulletin on changing the spindles to the larger size. 75-TM4 and 75A-TM4. A service bulletin is NOT a recall. They have a recall in 1974 for the rear wheel bearings but I you haven’t had failures with the rear bearings...

Be sure to check your battery posts for a good clean connection. Also check the negative battery cable where it connects to the passenger side of the engine block. Emery Stora > > Well here’s the update,… and i wish it was better news. > Having now tried the 3 main suspects in the system >...

If you are at 30 psi at 1500 rpm you can likely get it cooler if you drop the pressure to perhaps 25 psi. Your leak over the winter is likely from the seal on the clutch. The oil keeps this from leaking but if it sets over a winter it can dry out and leak a little. If you start the air...

Deb I have sent this out several times over the years. "1973 through 1976 models had two relays in that area. The one above the horn is the blower relay for the heater/ air-conditioning blower. Late 1977 and 1978 models had a third relay at the top which was a delay relay. The delay relay is...

You say “We’ll see if i can get it to crank without battery boost tmrw. If not, then i’m gonna have to look more closely at replacing the starter/solenoid. “ I would think that you would want to consider replacing the battery. Because if it will start with the boost but not with your engine...
