Thanks everybody !!

What I was hoping for, in part, was to keep all of the pulling power of the original 5.46 rear end, and get some top end speed with the double over transmission. Sort of have my cake and eat it too.

I have a single over triplex with the light aluminum case all ready to go in the truck, and I own an older Rockwell rear of about 4.11 that is in used condition and largely unknown (It isn't too pretty). With a higher ratio rear, I can definitely get more road speed - but with a 711 motor, I don't really have any extra grunt for the low end.

I'm curious Packer; does the double over quadruplex transmission have a larger case than the triplex - and would fitting be any issue? That transmission might be the best answer, if any were available. And does the "720" designator apply to the quadruplex as well as the triplex?

The idea of getting a 70 or 75 mph top end at redline is what I was thinking, too. That way an easy cruise of around 60 or 62 is comfortable for everyone involved - noise and fuel consumption are minimized, driver fear is reduced, and tickets are less of a concern. (Until now, I didn't think it was possible to get a speeding ticket in a B model !!)

To achieve the 75 mph top end - I calculated a need for a 3.59 final drive ratio, including the overdrive reduction and 22.5 rubber. To get there, I need a rear axle ratio of 4.10, using the single over triplex with the .86 over gear. With a double over transmission gear of .68, I get real close (3.71) with my original 5.46 rear end.

For "fine tuning", I still have the option of 24.5" wheels and tires.

Thanks again,

Paul VS

Matt,

Are you using a double over (#720) triplex with the 4.62 rear axle to get an 80 mph top end speed?

If it is a single overdrive (.86 gear) - then my math is seriously flawed - and that happens a lot !!

Let me know, before I do something stupid - Again. Just ask my wife.

Thanks,

Paul VS

Does anyone know where I might find the percentage of overdrive of the double overdrive triplex transmission that was available in the B model?

And - would anyone have one of these transmissions that they would like to part with?

Or - is it possible to purchase the gearset necessary to convert my single (.86) over triplex to a double over unit?

A .70 or so overdrive would let me use the good original 5.46 single reduction rear I have for a 65 mph or so top speed.

I am trying to avoid buying another rear end for my B67 project, and yet still have enough road speed to at least stay out of the way. And, I would really like to use the original housing with the Mack logo machined in the back.

Another reasonable alternative might be to find a good 4.17 ratio rear end from an R model - can anyone help me with one of these?

I will be at Macungie - I just need to know if I should bring a trailer - if someone has the parts available.

Or I can use our new BMT transportation assistance forum to get the parts from anywhere in the country to upstate NY.

Thanks,

Paul Van Scott

Charlie,

Glad it all worked out for you.

Hope to see that truck at the shows in the future - it is a looker !

Paul Van Scott

There was a fellow who called me a short while back with a Seagrave hook & ladder fire truck that was in Punxsatawny, Pa. and wanted to go to the Lousiville, Ky. area.

His name was Charlie Hatfield (not sure of his BMT member name). His phone # 502-939-8883.

Someone with a flat bed or a long drop deck looking for a back haul or a cheap load should call him for details. Seems that the truck was about 35' overall with some ladder overhang. It would have made a nice load on one of our drop decks with the ladders facing forward over the top deck.

I know that the truck rolls, I'm not sure if it runs. And I think that the storage yard might be able to help with loading the unit on your trailer. But you will need to confirm with the owner, as I am old and tend to lose some of the details.

Nice to see some activity on this new Transportation Board.

Thanks,

Paul Van Scott

Sounds good to me! I set up a Transportation Board forum under the Classifieds section and moved this topic into it to help get it started!

Hi everyone,

This idea of Rob's is exactly what I had in mind. I think it is too much to ask of Barry to try to keep a list current, as it will take some real coordination and time - something Barry gives us a lot of already!!

But having Barry post it here is critical to getting the information out to all of us.

Thanks to you both !

Looking forward to taking advantage of the new system. Should be no need to run any size truck empty ever again - unless we are drag racing.

Paul Van Scott

Thanks to everyone who called - this idea has been really well received.

We are planning to move Rob Swallow's R-model, as Rob was the 1st caller.

And just to prove that these things can work out - Rob's truck is being delivered, at his request, to the same place that we are loading up our own stuff !

There were at least four calls with vehicles close to Altoona, Pa. to be moved within the area that I specified.

When the situation comes up, we will do this again.

I wonder if we, as BMT members, could maintain a current list of available loads and available trucks for hire on our website? The currency of the list is most important, and probably the hardest to keep up.

The list should be limited, at least in my mind, to antique and hobbyist vehicles and parts, only, and to trucks that are willing to work by sharing the costs.

We are all moving around the country, in vehicles of all sizes, all the time. Might as well do it loaded. And if we can help out each other, and help out our hobby - all the better.

Just food for thought.

Thanks,

Paul Van Scott

I ran this message by Barry last night - he suggested it be posted here -

We are delivering a large piece of equipment to Altoona, Pa. on or about April 09 or 10 on one of our trucks. Our intention is to deadhead from Altoona to Bloomington, Ind. to load an old Peterbilt and a bunch of antique parts, then go down to south/central Kentucky and pick up an IH Transtar tractor for a friend of ours, and bring the whole pile home to upstate NY for our personal enjoyment. We can reverse the loading order with no problem.

The point of all this is - we will have an empty 52' spread axle step deck trailer and a four axle tractor in southwest Pa. on Monday April 09, or Tuesday April 10.

We like to help out antique and hobby truck people if possible.

We would be available to pick up an old vehicle or two, or heavy parts for old trucks, from the general Pittsburgh/Altoona, central Pa., or southeast Ohio areas going to Indiana, western Ohio, Kentucky or northern Tennessee. Basically we could do this for the price of fuel from point to point plus fuel from your delivery point to our nearest loading point (either north/central Ky., or southwest Ind.) Can't get any cheaper than that. We are going to make the trip empty anyway - this just defrays the cost a little.

The catch is - it has to be an antique or a hobby vehicle, and you have to have a method of getting it on and off the 30" high trailer deck. (loading ramp, fork lift etc.) We do not carry ramps or winches.

If you are interested - Please contact me here on this site, or by phone at (585) 509-4783 ASAP.

Thanks,

Paul Van Scott

Barry,

Do these vent window handles have the thru-bolt with them?

I'll call you to order a set.

Thanks,

Paul Van Scott

Hey Captain Kirk,

Interesting about the Willys pickup - I have one myself.

A 1960 4x4 Willys pickup completely restored to original condition, with a lot of help from Carl Walck, who I think is from down near you.

I will be putting mine up for sale to pay for the B67 restoration, as I really don't use the Willys like I thought I would.

Anyway - welcome to the forums - and best of luck with the bus, that looks like a cool project.

Paul Van Scott

Barry,

I think can speak for everbody - all 1,000 of us - when I say Thank You for all of the work and time that you put into this site.

It really is an enjoyable way to stay in touch with other people who share the same interestsl; and a great way to share information.

Thanks,

Paul Van Scott

Hey Freightrain,

I'm sure I'm not alone when I tell you I love those videos.

More than anything else - it gives me ammo to combat my wife playing the stereo at full volume !!

Sounds better too.

Thanks,

Paul Van Scott

This is a good looking bus - can you give us some history on it? And - power/transmission info?

Nice to have you on our forums.

Thanks,

Paul Van Scott

Hey Barry,

This might make a nice Truck of the Month.

And a nice way to welcome your customer to BMT.

Just a thought.

Paul Van Scott

I agree with replacing the floor with new panels, and adding bracing under the seat area.

I have the cab off my B67, and have had the cab sandblasted - what an eye opener.

What I thought were pretty solid floors are now about half gone !!

It looks like most of the floor pieces are easily removed, and you can duplicate the original panels.

I also found that the original driver's seat has actually torn the floor panel at one of the seat mounts - making the case for added bracing.

While you are at the floor repair - take a good look at the lower sections of the door hinge posts (A-pillars). These form the rear attach points for the front fenders, and are subject to severe corrosion. They are not easy to reach, and would be easier to work on if your floor panels were out.

Good Luck !

Paul Van Scott

Speed,

The man in New Jersey with the glitter shift knobs and black 20" steering wheels that you see on e-bay is Gary White. He's a nice guy and has a big assortment of the shift knobs. I'm sure somebody here has a phone number for him - I have misplaced it.

Good Luck.

Paul Van Scott

Thanks Barry, I'd love to see Truck of the Month started up again.

And - It's interesting to me how so many of us who believe that we can keep these old trucks running forever also believe in Santa Claus !!

Paul Van Scott

Barry,

Maybe we could poll to see if anyone wants to bring back the "Truck of the Month" feature ?

I know it's a lot of work - and probably a lot of that work needs to be done by you. So I will apologize in advance -

But it is one of the features I always looked forward to.

Thanks, and a big thanks for keeping these forums alive and kicking.

Paul Van Scott

hi,

I guess that I will make some. I have seen some that are crome plated and apear to be original mack stuff, but the diamond plate looks good too.

Thanks

Hi Fred,

I'm going to make mine too. I do plan to mount them inside the frame and use the space on the outside of the frame for toolboxes. (and maybe a beer cooler for the long hot truck shows)

See you in a couple of weeks.

Paul Van Scott

I've had pretty good luck with the epoxy as well. Take a dremel tool and clean out the cracks and make the crack wider below the surface of the crack(the epoxy will have less chance of cracking and falling out). After it hardens just sand it down and repaint the wheel. If you use a good brand of hardened paint it will last for years. You'll have to put in a lot of hours behind the wheel to wear it off.

Brad

Thanks guys, I'll give it a try !!

Paul VS

Does anyone have any experience repairing the cracks in a Mack steering wheel ? Would an epoxy filler color matched to the green color work ?

I really did not want to spend mega dollars to restore a really good original wheel; I just need to fix a couple of cracks. Also the wheel is the 20" B67 wheel, which is a little harder to come by - so I am reluctant to send it out.

Thanks in advance.

Paul Van Scott

Here are a couple pic of Dave McNaughton's B-Model at the Latrobe, PA 4th of July Parade! It was a little wet, but still a great time!

GREAT LOOKING TRUCK - THANKS FOR THE PICTURES.

Paul Van Scott

Paul,

Glad to hear you got a fire built in the old gal. Been wondering how you were doing since phone call. Sounds like still some problems in fuel system. Try adding pressure gauge where fuel goes in pump to check transfer pump psi. Then, open throttle (while running, of course). If rpm picks up any, fuel psi should increase. Referance - my old wrecker will show about 20 psi in hard pull at 1500 rpm. Another possibabilty - governor problems could be limiting rack travel. Pull the big acron nut that covers rack on front of pump, start engine, try pulling rack forward to see if rpms raise. Holler back, interested in hearing more.

Over & out from Ignorant Ridge!!!!!!!!!!!!!!!!!!!!!!!!!!!

Thanks everybody - it will be a few weeks before I am able to get back to the B67 - Work keeps getting in the way.

Fred - I got your phone # and I will call about the pump, and maybe trading it. By the way, this is a END673N.

Tom - I've been afraid to take off that acorn nut - I have no clue what's inside that pump - but I'm thinking you're onto something and I will try it. If it all comes apart in my hand - I'll bring it out to you!

Pictures will taken soon - before the old girl heads into the shop.

Thanks Again,

Paul VS

thats what I like to hear, another truck saved from rusting away. What part of the country are you from? I take all of my pumps and injectors to Joliff diesel here in southern Indiana. He is real good. He always like to see the old pumps thats on the 711 and 673. they are so big he has to walk in to one and look around, maybe take a chair along incase he gets tired, or so he told me with a big chuckle.

good luck

Fred

Thanks Fred, I am in upstate New York (Rochester area), and I could send the pump and injectors out to anywhere, if you thought that it was worth it.

This is a nice old truck - almost no rust at all, in fact, it still has original green paint on the floorboards.

Thanks again,

Paul Van Scott

After numerous failed attempts, today I was able to get enough new, clean fuel through the system and got my B67 to run.

This after a twenty something year spell of sitting.

I had already checked the oil sump for water - none, and topped up the radiator with anti-freeze - no leaks. I had cleaned and oiled the foot throttle and checked the shut-off operation - all OK.

Sounds healthy, no knocks or unusual noise. The injection pump is probably fouled as I have almost no throttle response, but at least I know it runs and doesn't have any leaks or any apparent cracks in the big parts.

Does anyone have a suggestion for a shop to take the fuel pump and injectors for testing and rebuilding and/or replacement?

Thanks,

Paul VS

Does anyone have any ideas or know of any conversion parts to change a B67 single axle from original springs to air bag suspension?

Before I get too far along in my restoration project, it makes sense to decide now if I am going to leave the original spring suspension, and deal with the hard ride, or modify the truck with air bags, and end up with a more user friendly, although non-original, truck.

This is a cab-off full restoration, so access and fabrication issues are minimized now.

It is my intent to use the truck with a single axle Fontaine low boy trailer, but I doubt if I will ever put any real weight on it.

Thanks in Advance,

Paul Van Scott
