I think you can get the license but can't drive without the card...although thinking about it I had to show have the card to take the test if memory serves...damn rules are all over the place.

I never saw such a thing but it's cool. It would be handy to have around the shop for sure....no more scratching your head to figure out how to pick up something heavy! Be careful with it but enjoy.

Keep looking and as Fxfymn said drop the guy a note on e-bay just in case it goes south..There are lots of B-models around. Watch e-bay and craigs list for starters. Local auto trader type weekly for sale listings have old trucks once in a while too. I didn't note your location but there are typically guys around that have them for sale. Getting a good price is sometimes tough but..be patient good luck!

That's just stupid. That's not a pole, its "the shaft". What a dope...Does he mean dollars? I've seen it all now.

Looks good for the money so far. I'd be working a deal if I were you.

If memory serves tighten the inner nut until you get drag and when using a jamb nut you back off 1/3 turn then tighten the jamb nut and lock it in place. It's not so much a torque spec as a procedure. When using a single nut and cotter pin the process is 1/6th turn and then pin it or lock it in place. I'd get some old school wheel bearing grease and use that although I'm not aware of a problem with newer stuff in the older applications. That sound right? Greg

Aside from the rust and obvious problems, I'd look for a good drive train. Rebuilding an engine is costly and time consuming. Find one that starts runs and drives. Watch for trucks that smoke a lot particularly after they are warmed up. Tires and brakes are expensive too. If all the tires are shot you can figure on a big investment to get it road worthy. I'd find one running and driving. You can figure the balance of costs from there before you lay the cash down. Allow money for the unseen too...there are always problems you will miss. Good luck Greg

Thank you for that. Our memories can grow short and our attitudes come to expect all that we have rather than be grateful for it. God bless our Veterans!

I'd love to hear that pull something heavy up a long hill (not too steep)...I bet it sounds cool!

A fine looking Mack. Welcome aboard.

I paid $3000 for mine but the original engine is gone. Runs and drives well so I figure I'm ok with that. I do need 3-4 tires to be comfortalbe with what I'm doing. Keeping the 1100R24's. I was offered $2500 for it. They don't bring much over scrap price unless they are really clean and shiney. Just figured out what was looking funny with the radiator on this truck. It's a b-81 radiator with the 815 shutters fitted onto it. The bulldog should be in front of the cap not on top of it. That is the narrow skinny version out of the 81's, That was bugging me. The hood doesn't fit right and there is a gap between the shutters and the bumper that isn't supposed to be there. What is the year and full serial number out of curiosity? Greg

Don't know how I managed to miss this entire thread but I did. Wow. It would be nice to have the V8...I've got the E6-250 HP...It's a nice engine and runs great but having the right one between the rails would be something special. I had the card of a guy who had an 815 with the Allison down near perthamboy where mine came from. I didn't know it was there till I went to buy the one I have...I like the Quad but the Allisons were made for trucks rated for heavy heavy hauling. Anyway keep the engine retire the truck! It's too darn rare to screw up! We never did get the SN on that beast did we???

Funny you mention that. I sent the four out to be rebuilt mostly to save time and ensure quality work. The post office (the institution with which I will never send packages again) did me a favor and lost one each of the front and rear cylinders. I can do one side and not the other. I need a 2" and I believe an 1 3/4" to finish the set. I don't recall that they were left/right handed so any should work unless you know otherwise. Let me know! I need to buy some somewhere. Thanks Greg

It seams like they are always about twice as bad as you think at first. You notice things as you go. I think that if it runs and drives and the brakes are good you are way ahead of the game. Engines get expensive fast and are labor intensive to fix if they are in bad shape. The sheet metal is thick and can be welded up with new steel fairly easily. I wish my frame was better off but it is all salvageable as DigDug says. I'd go for it. Is that just an 81? the air cleaner is what I think of as an 83 or 815 or 87 model...with the two elbows before it turns into the engine compartment. I think the 81's usually have the skinny tube instead. Maybe I read too much into it and it was a model year thing as well.

That's a great idea. I have two doors in better shape off of a parts truck I picked clean. I have to fix up where mirror brackets were welded on and bolted but the damage should be easily fixed. That door has no bottom...the hornets love to build a nest inside the hole where the lock should be every year. I hate those suckers. I'll have to find a spot in the garage for that old door...that's art!

Ok great. That is a start. I'll study the situation this weekend and see what I can come up with for a plan. I will also look for the welding guidance in mack manual. It has to be on the internet somewhere. Thanks for the help! Greg

I'm curious about this topic. The 815sx has the double frame and is spread in areas and has some cracks out within 3-4 feet of the end at the 90 degree bend on top on one side. Dear old Dad says cracked frames = scrap. Can someone tell me the details on what is legal and not? Can I weld it up? Do I have to "hide" the work with welding grinding then body work or am I messing with fire here? Do I need frame specs from Mack to size the outer frame like done in this thread? What exactly are the bolts? The only shoulder bolts I know of are the socket head cap screw kind used in industrial equipment. They usually have a smaller thread and nut size compared to the bolt body diameter. I know those are not the right thing. My plan had been to repair as needed to make it look right and be strong with proper welding etc. (the frame is heat treated too adding to the questions) Guidance is much appreciated as I really want to make the truck look right, work right and be safe and proper. I need to know now as its time to finalize the restoration plans. Thanks

The fire engine is running. I just re-torqued the heads per instructions and am working to finish that up and get the hood in place. The brake booster is out for rebuild and I'm hunting down two wheel cylinders. Other than that I need to tighten up some wiring, make sure the fuel pump and filter can handle the job, and get some 9:00R20's on it. It's really close and I plan on having it in the Woburn parade next October if I can.

Agreed! the next biggest issue is the lack of political will to do ANYTHING about the situation. The Dems want paid voters and the Republicans want cheap labor. It's all at the expense of America and the Americans. It is truly time for a third party and we need to push for a constitutional convention to regain STATE's rights and put the fed back where it belongs...UNDER the control of the people and not IN control of the people. Hear out Mark Levin some time. Read his book.

I got the chance to put the truck inside for the winter so I'm going to be busy tearing off the old sheet metal, swapping stuff out and or repairing what I need to to get some nice fenders put together. I'm planning to get some paint and spray all of it when its ready and hopefully by spring I will have fixed the rust and the holes and made her presentable. I'm trying to takes some pictures as I go cause I know we all love pictures. I found this in Perthamboy NJ a few years ago. Dave was selling it for his 80+ year old father who has owned and operated it for many years. It was a dump truck with a big highway plow. I purchased just the cab and chasis. The 864 is gone and what I'm told is a 250 HP E6 is in there. It runs well although the starter sounds a little shakey. IT has a quadbox and shifts and drives well. I know the pitman arm is loose, the right front wheel bearing is way out of adjustment and one brake shoe in the rear is floating around. The brakes were recently done so hopefully a shoe repair or replacement will fix that issue. I don't have the bracket that holds the hood sides open. The radiator hods water just fine but the lower inside area has a bit of fin material missing. The R model air cleaner is up for grabs if somebody needs one. I got the B-83 oil bath unit from Radwill to make it stock which is my goal. IT has been red and orange but I believe red is original...Oh yah I guess I need to send to the museum for the paperwork! I think its time to do that. I hope to haul around Dad's hand start big bore GP (34) and the 39 hand start A. Now that Ma passed he keeps busy and he likes the truck/tracktor shows. I'll get a 5th wheel and a pintle hitch and hopefully be able to lug some stuff around. The 100R24's are mostly ok and if I replace the steer tires and recap three I should be back to a good set of 10 with two new steers...funds permitting! Besides that some fenders and flaps as well as some new air lines and controls and well you get the idea...It's going to be busy. Thanks for watching. Greg

That is great. Nice to bring one home and it looks fantastic. What does it need? I'd make sure it starts, drives and the all important stops. There is a ton of good guys and great information on here so you are in the right place. Take more pictures and keep us posted. Greg

Big patch on top of left fender...rusty but it would be miraculous if it were not.. Love the truck.

I'm open tell me what you need. Thanks

I've got to make some room so I'm going to offer up the 707C engine I took for items I needed in the 707A. It is complete except for pistons. The heads appear to have been rebuilt some time in the past and all of it is useable. It was a good running motor from a B model. Any interest in any part give me a shout and we can figure something out. I can ship most stuff and if it comes to it I will figure out a way to ship all of it if need be. I'd prefer it be picked up. I also have a r model air cleaner on e-bay if anybody is interested. PM me for questions and info. Don't want this at the scrap yard either. Thanks Greg

Hey that is a nice one. Please keep us posted on the tear down and rebuild. Enjoy it. Greg
