B model jacks

[SuperB]

I was just wondering what style & brand the jacks were that came with the B model trucks? Assuming they originally came with one. Would anyone happen to know?  

[mechohaulic]

bottle jacks they were; brand =can't remember. the jacks became an option later yrs. Scovill manufacturing still ordered the jacks with the new trucks they bought even up to the R's in the '70's.

[mowerman]

i’m a little younger, but I remember the older fellas  telling me they used to come with a jack and a lug wrench sorry I got nothing else 

[T-Mack1]

25 ton bottle jack are still an available option on new Mack's.   Not many people order them.  They take up space and the service truck that comes usually has them.

Would save alotta money sending people down the road with a spare tire and tools to change it … but these days trying to get drivers to do anything is a whole different subject lol… bob

I started with guys with guys who were bootleg coal haulers during the depression. They carried a vulcanizing clamp thing that burned gasoline to patch their own tubes. They broke the tires down themselves by running another truck over it to break the bead. If they tore a large hole in a tire they would put a magazine inside the tire to cover the hole and use another tube.

I don't think I'd want your average driver today to even change his own tire

No, you don't. They're basically just a steering wheel holder at best, and half can't even do that right. 

[mowerman]

haha,,,,,i broke in with guys that started on chain drives and side curtains,,myself,,,and these guys were never in a hurry to do anything,,,,,dont know what happened in between and why everyone is in such a big hurry these days,,,and why everyone is so lazy now,,bob

One Jamoke saw me patching a tube on one of my trailer tires (I had picked up a nail in a jobsite) before I went into dinner.

He commented how "he wasn't paid enough to do that kind of work".

I asked him what he did when he got a flat?

Oh I call road service.

Ok what does that cost?

I don't know, company pays

Ok how much drive time did you loose?

 Only an hour or so

 Well I can patch this tube, re install in the tire and inflate in about 30-40 min, Given road service calls prices I am paying myself between $125- $200/ hr, how much are you paid?

silence.

I always had a mounted spare and tools to change them. Gotta love spokes, inner or outer, done in 20 mins with hand tools.

lol yes spoke wheels . I’ve done 1 million of them. my old company really didn’t want us doing anything to the trucks. Our average road calls were 2 to 3 hours but we also got paid to sit there. I want to say between 1000 and 1200 bucks to come out I don’t know for sure I never even saw the bills. They were just direct bill the company. I did see a loves Bill one time that was right there at the shop. I think it was close to 1000 bucks. I don’t know about any of your other guys but been in loves twice and Winnemucca, Nevada right in front of their door and it was a three hour delay. I’ve never seen anybody works so slow.

Its hard to beat spokes if you want to be self sufficient and do your own work in a more or less shade tree scenario. 

[mowerman]

Well, my bud wheels seem to be a little easier to dismount the tires and mount them. I’ve never done them, but I watched a lot of guys change them and it doesn’t take them very long at all. But yes, I do prefer spokes

Disks or spokes, take the same to mount/dismount. Tubeless vs tube type can vary.

The rim portion of a disk and spoke are the same (ok, except for Firestone RH 5 deg) so mount time is the same.

When you are your own carrier, it all comes out of your pocket, the more you keep the better off you are. When I can do it faster and cheaper, I am both money and time ahead!

[mowerman]

Ha ha I guess I meant to say tubeless seems be a little easier to pull apart and yes, carrying your own spare stuff as the way to go if it’s coming out of your pocket

[mowerman]

besides, you don’t have a tire spreader on the road for tube type those things are God sent

Kinda hard to believe it was 50 years ago when I was using one

[Geoff Weeks]

Yes, I know it is wrong, and I very rarely did it, but needs must when the devil drives, a little starting fluid will pop the bead on.

Did it once on a trailer for a guy. He had hit a chunk of concrete and bent the steel rim on those real low profile 22.5 tires they run on a step-deck.

 Took my bottle jack and a 4x4 with the damage part up, jacked it back mostly round, and soaped up the bead with hand cleaner, then popped the tire back with starting fluid.

 He was in Ontario and they take a very dim view of wheel end problems, he had no Canadian cash or a credit card, I got him back across the boarder, with that trick.

I've done the starting fluid thing many times. I never saw it damage the tire. I've even used a piece of mudflap or a McCall's magazine for a boot in a tube type a few times. I'm not sitting on the road dead waiting to be preyed upon by some vulture or some idiot that turns everything into a project.

I wouldn't let a Loves, a Flying J, a Pilot or any other chain store mechanic touch anything. Those places only hire idiots

At very least it puts combustion gases in the tire, that and some moisture will likely result in acid formation.  Then there is the issue if not all the ether combusts, then you could have a flammable mix in the tire itself.

 All in all it is to be avoided if possible, but yes, I admit to having done it as well.

then there is this:

I've mounted tubeless tires with the ether and run them until I wore them out, then sent them to be capped, and ran them God knows how long, and never had a problem. Sure I'd rather have a tank blaster, but sometimes you got to work with what you got. I usually hear BS about doing it from the same kind of guy that will tell you that recaps on the steering axle are illegal

[Geoff Weeks]

You will not hear that BS about caps from me! Only illegal on "passenger carrying vehicles" (I.E. bus). 

Ether in tires is just "not best practice", as I said before, needs must when the devil drives.  I have a blaster tank, so I use that.

I have seen more rust inside the rim after ether was used and it was run for a long time. You can still smell it when you break down the tire.

I would run my casings for 3 treads before retiring, they were pulled at that point still "capable" but the age made it unwise. I did an experiment on a few and put a 3 cap on, but the casing failed before that 3 cap wore out.

 That is why I used "best practice", tires were a major cost, and the better I cared for them the less they cost me over the long haul.

Like most post here - this has strayed a long ways -

Attached is a scan from the dealer price manual for my B75. Looks like three choices were 5, 8 and 12 ton. Prices were quite reasonable. The sheet just lists them as "jacks".

 

 

[SuperB]

Thanks for posting the chart. To tell you the truth, I didn't even know if the jacks that Mack provided were hydraulic or mechanical. So it looks like a B61 would have gotten an 8 or 12 ton. The build sheet lists the lug wrenches that came with the truck too, but I can't even find a picture anywhere of what those things looked like.

I can almost picture a B Model book I have with those pictures. It was a two volume book with lots of pictures. I'll look and see if I can find it.
