Start soaking it. I would then start fabbing up some kind of homemade wrench to get ahold of the adapter out around the pins. That way you can't hurt the adapter itself. Some pipe with notches cut to fit the pins? Weld it to something you can use a 1" breaker bar on, or just weld a long bar on? Then heat and start turning. What is the adapter size? Big diameter? Length? Pin sizes? If you can't make it, maybe someone come up with pieces to help.

The Mack is a small cubic inch, low HP, low compression engine, thus it has very little braking effect compared to a bigger Cummins or Cat. My 673 had a block heater. Never needed it, even when it was parked outside the first couple winters. It would start, unaided(no ether) even at near single digits. I was thoroughly amazed. Yes, I had good batteries in it, and it would build some heat and fire off. I removed it once I put the spin on filters(new mount was in the way). It's in the garage all winter so it is not necessary to have one. It was brutal to get that threaded plug out, took some heat and chiseling. Do with the truck as you please. You should hear the grief I got for putting an air starter on mine!! OR air steering? OR Jakes, or....(whatever I chose next). Build it to your liking.

Welcome to the forums. Sorry about the bad luck at the show. There are plenty of parts to be had. Check the For Sale forums here. Mike(Superdog) is the resident B model parts guy with a very large collection of parts trucks in Iowa.

Whacko meltdown in 3,,,2,,,1.................

I was thinking the EXACT same thing as I was reading Yardo's post. Then I scrolled down and saw this. Perfect. Mack Tech, agree. Seems the wacko's aren't everywhere(yet). We don't have issues in my town for the most part. People mind their P's/Q's and go on with life. I have not seen anything on local news about protesting. Save the day when it happens!

You lucky squirrel!!!

That Wisconsin storm rolled through NE Ohio yesterday morning. I had buddies at a race up by the lake and they posted videos. WOW>....they got hammered. The track was washed out, things torn up. I was one hour south and nothing here. Woke up this morning to no a/c! Seems the furnace blower motor is tuckered out. Ugh. I got it running, but need to come up with new motor PRONTO! I'm going to get the house cooled down then pull the motor and try to get some oil in the bearings to help milk it along.

I gathered up pieces and put them on my 237. Noticeable function. Not drastic, but for my truck/trailer it does hold it well on the hills I deal with. No riding the brakes anymore. Yes, cost effectiveness? Eh, like mentioned, not great, but I'm happy enough with them. If you find them, make sure everything is there. Many of the pieces are NLA from Mack(like lash caps), especially the older large valve stem motors(like mine). I had to go to Facebook and ask around. I got the needed parts given to me from a random person. Facebook can be a good thing.

Wow...had to zoom in. Seems strange?

My 237 came from a C cab. The tach attaches the same place as my old 673 NA motor. Look in front/below of the injection pump, right behind the front of the engine. Should have a place to attach cable on the accy drive for the air compressor. Found a good picture showing the blue tach cable: This is my old 673 motor, but it is the same set up.

Drove something similar many years back. Ryder rental. 427/5spd/2 spd rear. Gas was still way less then a buck a gallon!!

Back when I stretched my truck, my local little yard had a collection of small tanks that I picked from. Likely late model, aluminum, push in air fittings with mounting studs welded on for easy attachment(no straps). 7-8" dia, 2 ft+ long.

With the paint scheme and the red velour accents on the dash I'm betting someone was pretty proud of it when it was new.

From concern over a member that was last on here just a few short weeks ago.............. to....................... this...............

Now I see the Bluebird in it. That raised roof had me disconbobulated, and knew it wasn't a std school bus. They stretched the front frame rails and moved the axle forward and reskinned the lower sides of the bus to remove the wheelwells.

Welcome to the forums.

Definitely a cut/paste job. Cool none the less.

I've used similar, but in blue/black and red/black bought at local Joanne Fabrics. Likely not the identical marble pattern, but very similar. Do you have local upholstery shops that might find something? Or is that where you checked?

Typically the first two digits are the torque rating(80= 800 ft/lbs). The 3 is three speeds. Not sure what the "1" denotes. The letter is typically the gear ratio. I used to have a Spicer sheet saved that listed everything. Found this: AUXILIARY TRANSMISSION: Spicer 8031G, 8035G; reductions: 1.29, 1.00, .84. 8031C, 2.59, 1.00, .75. 8341A, 2.40, 1.29, 1.00, .84

Aaron Bento works/worked on that truck. He posted on JOT some time back about questions about the Hall Scott.

I've broken the bumpers on my race car a couple times. I always start with a piece of 16ga metal underneath to hold things in place and then fiberglass to hold it. They shake and wobble while driving, but nothing has cracked or broken.

I remember when the fastest street car stuff was coming out in the 90's. Buddy ran his 90 Mustang deep in the 10's with no cage, nothing but a shoulder belt and the track was good with it. Not today. Not with the world we live in now. Watch your 1/8 mile times also. There are cut offs for that also, so you definitely want to sandbag it til you want to get throw out LOL! I'm sure the tech guys will realize you can go way faster then what you are telling them.

Yup, 11.99 is the NHRA cut off for roll bar, etc(I think IHRA is 11.49. Yes they have different). 13.99 for convertibles. Some tracks are a bit touchier about ET breaks then others. Something bad happens and things can get ugly if the sanctioning body finds out you knew it was too fast, blah, blah, blah. Yes, it's only .o1 of a second, but there has to be a cut off some place.

New cars have plenty of exempts on the safety equipment that is mandatory for an older car. Roll cage, 5 pt harness, diapers, etc. They allow the new cars to run deep in the 10's without a lick of added expense(not that the car isn't expensive to begin with) because no one would run them if they had to cut them up to make them legal on the track. That's why "Street outlaws' is so popular(not me). I haven't watched a televised event in a long time. Just doesn't do anything for me. That goes for roundy round too. I couldn't even imagine trying to run an NHRA event. Ugh, my pockets ain't that deep. But I'm just a bracket racer, thus I don't care how fast I am. I tell everyone that if I was worried about being fast.... I wouldn't have started with a 4600# wagon!!!!
