Tach drive. I aasume the tach on the dash does not work. What is the black tube hanging in the front of the picture? Looks like a tach cable.

My thread is 1.125. the nut is about 1 7/8" hex. Here is the whole drag link assembly hanging on a spare box I have. It is the same as what is on my truck. I had to swap everything to get the air assist bolted up. Apparently the air set up came from a lighter front axle and the joint at the spindle was not correct. I have the FA517 axle.

Ya, bit nip here last week in NE Ohio. Be 55 on Friday! Watched a YouTube channel the other day. He showed the thermometer at -50*. Yowza. Took some finesse and lots of heat to get the ol highboy running! I remember back in the mid 80s, my 70 f100 and the slow start running 20w50 oil and the transmission having 85w140 in it and would stall the engine if you engaged the clutch. Fun days!

I have the pitman arm off my B when I converted to air assist. I don't know if they used different splines? Diameters?

Easiest way to post a video is use Youtube and paste a link. This forum does not handle large downloaded video files easily.

Translation: "I have a Mack F763ST truck from the year 1972. I need a technical sheet for this vehicle. If someone can help me." Are you looking for engine specs? Chassis? Transmission?

NE ohio is supposed to get it early tomorrow morning. Owner gave us the extra day off so don't have to deal with getting in through the supposed mess that is coming. Then off til Jan 3rd.

Ya. All back to "abnormal" LOL! Got to sleep til 6am. Wahoo!

I've been through a few times. I do travel randomly for work. Pretty painless trip this time other then having to get up at 3 am for two days to get to the airport.

Morning Dan. I'm currently sitting in Atlanta airport waiting on my connection flight back home. Up at 3am again this morning. Ugh, can't wait to get back to normal schedule tomorrow.

Prerty sure that is all Dans handywork! "High binder".......biggest understatement EVER! I get a nose bleed just looking up at that cab. Lol.

Gregs is Blue and silver

Looks fantastic!

LOL.....

My mother tried to plan her death down to the letter. Too bad it doesn't work that way. 3 yrs in nursing home, she was miserable and just wanted to be done. It was a relief for all of us on that final day.

Ya, Greg is still running that old MH. Met up at Harrisonburg, VA convention. Saw him after you saw me over the fence Brocky! He was parked down the aisle from me, towards the campgrounds. Ya, he gave up on the old Mack powerplant after it failed the second time. It's now a CattyMack.....LOL.

I met him in jr high. He went to different high school, then he joined the marines and didn't keep track of him until I saw him here. We chatted a few times through the years and I would run into him at the Dover steam show in Aug.

With the pictures Tim posted lately I figured he was still in NZ or the like. Pretty landscape and farming. Guess not? Tom, Rob bought that bike here by me. I went and looked at it for him. Then he did his typical midnight run to me and picked it up. I drove the trusty rusty Dodge to my house and he rode the bike. Once at my place he loaded it in the back of the dodge and off he went Another time he bought some big antique floor jack by me. I brought it home and he made a run over to get it. Another trip was for 12v71 Detroit parts from a buddy of mine. An old friend of mine that was on here(greg ryder) with the old A model fire truck flatbed came over and we made an evening out of collecting parts. Greg passed away suddenly a few years back. I never knew until I saw Adelmans had his truck for sale.

Friend works at a fab shop so anything I need material for, he gives me. He picks up the drops off the shear and gives me the pieces. He'll hand me a big bundle every once in a while.

Hmmm, maybe I did use the head studs? I just don't remember the details, or if I used this in the front or back? It's like a 6.5" span across the holes. It doesn't really fit well now since I put jakes on the engine. The Jake spacers kinda block things.

Yup, he's on FB and I see him posting occasionally. Ya, Ten-50 has the rollback. Haven't seen much from him lately. I think he may have taken hiatus from that last blowup on here when things got heated. Rob and I conversed a lot way back. He made a few trips to my place to pick up items. He vanished, came back, we spoke once, he retired and dashed away and never returned a call. He always had a full plate and never ending projects. I think he visits incognito, reads a bit and goes off, never to be seen or heard.

I should have a lifting bracket I made for mine. It's been so long I don't recall what end I bolted it to. Don't think I used headbolts either even though I pulled the heads off. I'll see if I can find it and post a picture.

Quick release is a small box with a 1" hole in the bottom that releases air pressure when you let off the brakes to "quickly" release the brakes. They are mounted right at the axle with the two air lines going to the cans (There two, one for service, one for parking brakes). They do fail, and like you mention, it will leak air on application instead of release. The front axle brakes will have a similar item. It is what gives that air Woosh sound when you release the brakes.
