When this was happening it was above 40f.

It builds right to 150 psi and the relief valve opens but the compressor continues to build pressure. The pressure doesn't drop it stays high.

I will check those lines. I suspect they are plugged or failing. Thank you very much.

While driving a r model home the air pressure gauge started to climb right to 150 psi. For some time the truck was spitting at 120. Then it stopped and it would climb right to 150 psi. I changed the governor and it was fine for 10 miles or so. It now climbs right to 150psi. I was bob tailing and ran with the trailer valve open. There's a finned canister behind the cab. It has air in and air out along with some wires all cobbled together. Any info or ideas would be greatly appreciated.

I found a fiberglass sunvisor on an r model in a junk yard. It's perfect and it's on a steel dash truck. Will the visor fit the later fat cabs with a plastic dash?

Service tire still does them.

12 hours punch in to punch out for the day or log on log off needs a log. My dad has been worried about this for some time. He lucked out for now his truck is a 99. Hopefully he will be retired before things change any ore for the worse.

I've been watching the purple wave auction. I'm in NE Pa. That could become costly.

I'm looking to buy an r700. I've looked at quite a few trucks. Most have pretty bad cabs. Hence the roof skin wanted post. Any help would be well appreciated. Truck will not be exported. I don't have a preference on engine and trans specs. Just looking for a clean truck to restore.

I called Watts. They do have them available as well as the rear panels. The panels are kinda pricey, but there's a price for everything.

Looking for a roof panel for an r model mack.

Might be a stupid question but did Mack use any left handed threads on the wheel studs or caps in this case? I know some car manufacturers did back in the day.

I drive by that Goods Mack a few times a week and always wondered how it would handle.

Truck is already bought. Not by me though.

I was wondering if anyone on here has altered the rear springs to improve the ride of the truck. It's a single axle. I have considered cutting an inch or 2 off the ends of each spring and Possibly removing the 3rd and 5th leaf. I still run bias ply tires. An air ride swap is also doable, however I would like to keep the rear in the truck. Any thoughts?

I have a 74 with 237/ 5 speed and it has the drum.

No the one I have is different. It puts the stack out more towards cab corner so the stack will clear sleeper bump out. Thank you though

I'm looking for a pass side exhaust bracket for a 74 f model mack. I'm also looking for an air ride mack cutoff.

Yes sir that is the b and it is a good looking truck. The magnum does need frame work in the rear. It never crossed my mind that it would be a double frame truck. I still am amazed.

I have a slider that takes horrible pics, and I felt that taking pics would have crossed a line.

It was a pleasure meeting you and your son at York. What would you have in mind for a trade? My true passion is pre war Fords. Mainly model a's.

I think it's time to let my truck go. It has an endt675 engine, and a 5 speed trans. 322,00 miles. The truck was parked in 1991 and stored indoors until 2012. I have the full report and book from the mack museum. The inside of the truck was fully gutted, cleaned, and placed back in. There is a brand new mattress in the sleeper as well. All interior lights and gauge lights replaced. The Floors are soft in some places. The cab was waxed, seam sealed, along with the pass side, tool box area repaired( it is not body worked yet). The exhaust and intake brackets are powder coated satin black. The exhaust is new along with the air filter. The water pump, thermostat and alternator are new, radiator repaired. Truck has new steers, dr rear brakes, new rear pots, 4 new batteries, front and rear mud flaps, all fuel lines are new, hydraulic tilt system completely rebuilt. Front glass has a small chip other glass is good. Chassis was wire wheeled and painted black. All fluids are new along with the filters. I drive the truck everywhere. It's first run was to the York show. It doesn't leak any liquids or give me any issues what so ever. Will take and post pics next weekend. Not sure what this is worth so make me an offer. My cell is 570-561-3569.

I also had a lot of algae in the tanks when I bought it.

I was thinking something in the pump was weak or malfunctioning.
