Popular Post JAvery289 Posted April 7, 2023 Popular Post Share Posted April 7, 2023 So I've literally been watching this truck move maybe once every 4 or 5 years since about 1998. I finally decided to save it (or at least try) I bought this truck and another one like it that is really (REALLY) rough in the hopes of bringing the better one back to into service to haul a trailer for my toys. Started work today, cleaned out ALL of the intake pipes, and air filter looking for any critters that needed eviction. Swapped some boots and intake pipes with the donor truck. Managed to free up the injection pump linkages (shut down, and throttle). Finally I was able to bar the engine over. Rear brakes are newer 30/30 style cans, I caged them and beat on the drums, front appear to be type 24's, almost all of the air lines have perished and need to be re-run. It has an air starter. I'm new to working on a B Series Mack, and I have some questions if anyone on here is generous enough to answer them. 1. What is the difficulty in sourcing new/used wheel hub parts to swap over from Dayton/Spoke over to pilot hub? 2. Is a 1962 Mack B a positive ground, or negative ground? 12v? 6V? (Does anyone make a full wiring kit, I can make it myself....but....ease of install is worth it to me) 3. Being a B67 it has the contour cab, what kind of issues would I run into (if any) if I swapped the contour cab out for a normal flat back cab? Will it destroy the value of the truck? 4. Anything else I should check out before attempting to start this engine? (The fuel in the tanks is very clean and smells as it should) 5. Anyone have floor pan templates? Or better yet a whole decent contour cab? Thanks, I look forward to the knowledge of the community 😃 6 Quote Link to comment Share on other sites More sharing options...
tjc transport Posted April 7, 2023 Share Posted April 7, 2023 welcome to BMT!! good on you for saving another old dog! since you have air started the electrical should be 12 volt positive ground. unless it was converted to negative ground sometime over the past 60 years.

mechohaulic Posted April 7, 2023 Share Posted April 7, 2023 first important question;;; where in CT is all this taking place??😁. technically by taking off the B67 contour cab swapping straight back it will become a B61 (or other). the 67 designation referred to contour cab , made to give more clearance for longer trailers coming into use in the day.

mechohaulic Posted April 7, 2023 Share Posted April 7, 2023 it's like an untouched piece of history. the brass emergency fuel shut off still there : even if it's disconnected. perry water filter , air valve passenger side fire wall was a major discussion a while back ; someone having tractor/ trailer air issue . mice still there and not paying rent = good air compressor and blast them out .LOL 1 Quote Link to comment Share on other sites More sharing options...
yarnall Posted April 8, 2023 Share Posted April 8, 2023 The contour cab was an option. On several models, including the B67. Most people don’t want the contour cab because of the decreased room in the cab. It would decrease the uniqueness of the truck to put a flat back cab on but not the value. Have fun with it.

Popular Post Brocky Posted April 8, 2023 Popular Post Share Posted April 8, 2023 In reference to switching the hubs / wheels to hub piloted Budds: IMHO, I am more of a purist!!! Please leave the period correct Spoke / Dayton wheels on the truck!! Unless you are a freak for a lot of BLING!! Just changing the rims and tires to tubeless 22.5 radials will not be that noticeable at shows and improve the ride and handling.. Especially since you will be operating it only as a hobby vehicle with short distances traveled per trip and no or light loads.. 3 1 Quote Brocky Link to comment Share on other sites More sharing options...

So the Truck is currently in Meriden CT, it will be going to Stratford VIA Wallingford. I work part-time for a truck repair shop and the boss gave the "okay" to tow in down to get it yard driving. I was tossing the idea of a standard cab mainly because there is another B model on site that has a decent cab, its a gas powered single axle dump truck, not sure what it is as far as numbers go. I don't mind the contour cab...but the one on the truck I'm attempting to save is going to need A LOT of sheet metal work, and that assessment is even before pulling the front windscreens off. 1 Quote Link to comment Share on other sites More sharing options...

However, the main issue I have with the spoke wheels is the rims, they are VERY rusty and I doubt I'll be able to find a big truck tire shop that will dismount them let alone put new rubber on them. What rims would work on these spokes? Is there an aftermarket for replacing the old two piece wheels for tubeless? Quote Link to comment Share on other sites More sharing options...

Another B67, and old Pratt & Whitney truck (posted on FB "Scrap Macks" group. It still has the asbestos heat shields above the exhaust manifold, and all of the air plumbing is intact and neat, too bad the double frame is rust jacked and the cab is completely rusted away. 1 Quote Link to comment Share on other sites More sharing options...

I appreciate it, I have to work out a time where I can use the small 25ton wrecker to tow the Red Mack, the Blue 'pratt' truck will need to be put on a landoll trailer. We're already working to clean up a spot in the back lot to park the trucks. 1 Quote Link to comment Share on other sites More sharing options...

Most things so far have come apart pretty quickly and easily. Monday I'll be ordering up the main supply line that feeds the air starter from the air start tank. 1 1 Quote Link to comment Share on other sites More sharing options...

It is a Monoshift, I was fairly surprised at it when I found out, I had initially assumed that all older Mack's had twin stick setups. The Mack Museum was able to get me the original spec sheet and this truck was built with the monoshift. The other truck (donor) has a twin stick setup. 1 1 Quote Link to comment Share on other sites More sharing options...
