Red Horse

How about some help. I have a Duplex behind a Maxidyne. I just got thr truck and have basically been driving it as a six speed. Any and all suggestions on properly shifting a Duplex would be aprreciated. I think the 1200-2100 rpm band makes splitting this a bit more difficult.

Ever try sending those numbers to Don Schumaker at Mack Museum?

Ok Guys, any thoughts?. About to sand blast my B chassis. FA-522 front axle and RAD 111 rear. 24" My question is, given the fact this thing is a 1960, what parts would you think would likely require replacememt- other then the obvious of linings, hoses diaphrams. I have a new set of Maxi's for the rear. I'm asssuming things like slack adjusters, shoes, bushings etc should stillbe available? Anythoughts would be appreciated. I'm not doing this yself so I have tothink about trade off of labor vs new etc.

Thx guys for the responses.

Any suggestios on best way to fix up a couple of cracks? Worst is about an 1/8". Typical B lime green. thx

Hey guys, thanks again

Paul, Larry, Thanks for the responses. Will look at both options. Bob

Guys, I want to convert my B to an alternator and get rid of the series parallel switch. I'm swapping cabs so all of the current wiring is junk. I assume if I buy a harness from say Top-O Hill or any other supplier, I will be getting a lot of stuff I don't need given the conversion to an alternator. Any thoughts? I have to believe many of you have "been there-done that"!

Guys, thank you all for your responses. Lizardskin looks pretty good, but as with so many of these things, a little creativity goesa long way. For example, I'm thinking Lizardskin on everything then perhaps plain syrofoam sheet on the cab back panel and even above in the headliner? Or if you are not talking about moving parts (doors) even expanding foam? As log as you don't get the kind that has too high an expansion rate

Guys, we are stripping my B cab before it goes to the soda blaster. As for the formed inplace insulation on the cab firewall (interior) anyone have any ideas as to what you replace that with? I'm sure no has any of that in inventory. Appreciate any suggestions.

Guys, Anyone out there bought any 11 x 24's lately? If so what brand and how much.?

Rod, thx for the tip!

Paul, Matt Pafhl, from Conn. was at the Macungie show in June and was selling off some inventory. Check out his webb site for contact info as he might have some more or have a line on reasonable replacement prices. Good thought on checking Mack dealers- its easy to get into the mindset of automatically thinking they WON't have inventory. Bob

Paul, Thx for response. Actually I should have mentioned the rubber gaskets. I did pick up the wing window rubber at a recent show at a very fair price. the only place I have seen windshield and rear window rubber is Watts, so if anyone has another source I would like to hear about it.. Although I would imagine that some of the door track material can be off the shelf bulk material that can be cut to length??? Bob

Guys, Anyone have any recent experience with getting new cab glass cut? Only good piece of glass I have is the back window. So I'm talking windshields, vent windows and door glass. Appreciate any cost info anyone might have.

If it had a 534 it was a 900, not an 800. I know you said the sheet metal was gone, but for what its worth, if it had a short cab-90 BBC- it would be an LN-900. If it had a long cab-106" BBC, it would be an L 900

Ok guys- For the front springs $950 pr. (these are 14 leaf) rears $1210 pr rear Helpers 495 pr Helper brkts 179 total $2834 Keep in mind this is a 35,000 LB rear with torque rods each side and a center torque rd going to the cross member. But like the Fram guy said.."pay me now or pay me later".

O'Dog, If you get lucky, you can find some nice ones. the B-61S I bought for the Cab (and as it turns out, engine and quadbox) Has a great looking set of springs- no rust between leaves. Of course when I go to sell it everyone says.."44 rears, dime a dozen!'

Freighttrain- A timely post! I'm debating if I should replace the springs on my 60 B-68X. this thing has a 35,000 lb. Rad 111 rear and I'm going to put a 10' dump on it and use it. Springs for this puppy with helpers will cost me $1550 for the rear and about 700 for the fronts. Your pictures convinced me. In particular as I intend to put a load on it every now and then.

Didn't think my first post went through??

Guys, Thanks for your input. The motor is sitting in a box trailer and I will check it out Monday and confirm the stud sizes. Bob PS You might have seen this B-61s in the classified section of WOT a couple of issues ago. It was the red one in FLA. I was told it was an early 60's but was actually built in Sept. of 65. Hopefully that is good news. Was delivered by Birmingham Mack to a Lawrence Lucas. The original order for the truck was through Prentiss Mack, Lafayette Ind. and the customer was Davis Trucking but somewhere along the line, the order was assigned to Birmingham Mack and their customer.

Guys- thx for all of your input. We pulled the engine and its sitting in a box trailer that I won't get to untill Monday when I can check out the head bolts. I'll Keep you posted. The truck was built in September 1965 so hopefully it has the new style head gasket . By the way, it was sold through Birmingham Ala. branch and original owner was Lawrence Lucas. One of the orders also indicates "Davis Trucking" as the customer and Prentiss Truck Sales, Lafayette Ind. as the dealer but that ticket was written in August and then the unit was assigned to Birmingham Mack in September. History is half the fun of these things. My B-68X was ordered in May 1960 by Albert Welch Inc. a good sized Boston Excavating contractor. They are still in business today and a buddy of mine isa field super for them. He mentioned this to one of the owners (grandson) whose comment was.."yeah- we probably still owe on it"! Bob

Well guys I bought a B-61S for the cab and it looks like the 711 in it is in much better shape then my old 673. No smoke and it sounds great. I have no experience with 711's. I came into the industry in the mid 60's when my company still had 673's and then transitioned to Maxidynes. What should I be looking for and what should I expect? The engine is a 1965 and I'm putting it and the quadbox that came with it, in my B-68X . I will have a 10' dump on it and I intend to use it every now and then to grab a load of stone for my driveway and/or help out at the fairgrounds. The 673 that repowered this old gasser is like I said, a smoker and it is noisy- plus its a Duplex so I think 'm ahead with this swap.
