You should be able to get them at your local tire shop. If not try Myers Tire Supply they have all kinds of things for tires. They have a 9 1/2" for $7.

I believe that according to DOT regs the fire extinguisher is not considered 'readily accessible'. It's difficult to reach all the way around the shifter and across the cab in an emergency. Prefered location is left side of drivers seat it's easy to get to and view the gauge during inspection. I know they don't like them in the luggage compartment either.

There were 400hp E9's. I think there was a 450hp in addition to the 440hp, not sure though.

New Mack Acquistion:
MidniteMechanic replied to Rob's topic in Antique and Classic Mack Trucks General Discussion
Hey Jeff, I've got a R753 with the Cat 1674 in. Soon it's going to get an E-9 twin turbo. Brian -
Hi All, I'm looking for a good used power steering box for a '78 R-model. Or a source for a rebuild kit. I'm not sure exactly what make the box is. Thanks for any help.

It was about 100 in Harrisburg, Pa today. Had the fine job of replacing a clutch today. Didn't have a dry stitch of clothing til I was done.

The VIN was listed in the Ebay ad. I have a list of the cab, frame and engine numbers.
-
According to the VIN it should be a 1693 CAT engine. It's an early version of the 3406.

Also check in the tanks for junk. Things like the foil from fuel treatment bottles have a funny way of getting in there. Or the chains off the fuel cap will cause problems. It depends how the system is plumbed, one tank will suck dry and the other tank will still be full or overflow due to fuel being returned but not used. It will drive you crazy til you find it.

Yes all pyro's work the same regardless of whose engine it is.
-
Keeping the RPM's and the boost pressure up are the best way to keep exhaust temps down. Lugging doesn't move enough air to keep things cool. Like Trent said most pyro probes are in the pipe after the turbo. Add about 200 degrees to the gauge reading to get close to the true temp going into the turbo. I wouldn't go much over 1200 degrees gauge for a long period.

Two outside filters are definately better than one under the hood. The intake air will be cooler. Just like when it rains, the air is more dense meaning more air into the cylinder. Besides even with a snorkel you'll never take in enough water to damage the engine. The best thing is to use a filter restriction gauge. Then you'll know when it's time to change the filters. I don't recomend cleaning them.

R Model Hood Scoops?
MidniteMechanic replied to Lmackattack's topic in Antique and Classic Mack Trucks General Discussion
I believe that trucks built at Hayward used a five digit VIN. I know my '74 was. Oddly the only thing aluminum is the doors. The rails and everything else is steel. -
Mack only used the V8 emblem on trucks that had a Mack V8. Also I think it was only used with the E9 series engine.

R Model Hood Scoops?
MidniteMechanic replied to Lmackattack's topic in Antique and Classic Mack Trucks General Discussion
My '74 RS has that same style hood. I think there pretty cool looking. -
That has to be a heck of a feeling when that cab starts to lean. Our Bulldogs could put the little rice burners to shame.
-
LOL, the freightshakers would have desenegrated with one stick.
-
HI, I was wondering how PAI industries are for quality parts and pricing compared to a Mack dealer. Thanks for the help.
-
Check your steering tires for being out of round or balance.

If you only use it for show or light loads, take some of the spring leafs out. Assuming you have a multileaf pack like 11 or 13 leafs. Just put a spacer block in of the same thickness as the leafs you took out. That will keep the front end the same height.
