Basil700

here in the US we had some GM and Cat engiens sneak into the long hood superliners R700 and RS700L

cummins was the most commonly off breed engine found under the hood. I remember roadway having alot of R700s with 318 detroits

Being reasonably new at this Mack game I never knew so many options were available for vendor engines, transmissions and back ends across the R model range of trucks.

Ive been putting a list together of all the R variations I can find with their build years and numbers built and its surprised me.

As you say the 318 detroits had a reasonable showing. 12V-71, 6V-71, 8V-92 Detroits were used also. Even the 3208 Cat had a go.

They used an inline 6 Scania in one of the R400 Models, Its a shame they didnt have with the Scania 14 liter V8 as an option also.

I gather Mack would have entertained the vendor gear to make their product more marketable to a wider audience.

Grant, havent rang Len yet.

Hello,

Thanks for the reply.

After my post this morning I got underneath with the pressure cleaner and blew a heap of crud out and found a second set of mounts further back !

Identical to the picture you posted of the Spicer auxiliery so my question is answered. Two sets of mounts about two feet apart.

Now could be the hard bit though, finding a 1241-C spicer box shouldnt be to hard but the mounting brackets on the box could be difficult.

Thanks again for your help.

Barry

Hi Jeff, Rod

Thanks for the feedback.

There doesnt seem to be many 700's around these days. Do you have any ideas on how many they did make here ?

Were most of them Mack V8's or was there a real mixture of engines. Swishy tells me Wettenalls had some Cummins powered ones.

Im still curious about the gearbox setup in this one of mine. There is a set of Mack rear trans mounts about 4'6" back from the flywheel housing that I cant work out. To far back for a maxitorque and to close for an aux. The picture isnt very clear but you can see the mount.

Barry

Hi Dave,

Im not sure why It didnt work. Thankyou for trying. It might be our machine playing up.

Barry

Howdy Dave,

There are a few Flintstones over here in WA so if you want chassis numbers for your list I could probibly help you out.

Barry

Hi Jeff,

I was just abit exited when the mag article turned up in the post. Got this copy from the Transport Hall of Fame in Alice.

Im going to run an add in Truckin life and see if someone will part with the particular mag it was in.

I managed to read the signwork on the door with a magnifying glass and it says Stevens Transport, Darwin so your bang on. With a little reserch yesterday I found out Stevens Transport was G & L Steven. George Steven. Im now on the hunt to try and find him. The boys from Shaw Trans in Darwin tell me Stevens havnt been around the NT for years now.

Mack in QLD are rattling through their archives to see what they can find on it so if they turn something up it may answer some of my questions.

Your information about who had what is interesting.

I think it is fitting to restore it as in the picture.

Thanks for the great info.

Barry

Hello,

My old R767 back in 1976

Barry

Thanks Jeff,

I found some pictures on the internet plus the info you just replied with so Im confident I will be able to work it out.

Thanks again,

Barry

Hello Again,

Brilliant to see a picture of one of these in new condition and great info about them, thankyou.

#32# has two sticks so I assumed it to be a quadruplex.

I dont want particuarly want one for myself but would like to see one saved and are willing to help in the cause.

Barry

Howdy All,

Thankyou for the comments.

The truck was built with a direct in 5th maxitorque followed by a spicer 1241-C aux.

I have found a spicer aux box and are looking for an O/D main box to give me a little more speed when running empty.

Barry

There are a small group of us including the original driver of Number #32# pictured are going to try and save this one. It doesnt matter who's shed it ends up in as long as it stays together.

Alot of people have been trying to buy it over the years.

The other three are in a sad state but this one is reasonably complete.

I will let you know what the outcome is in the future.

Barry

Hello,

I will be going past these trucks today so I will get some more pictures and post them in a few days when im back.

The trucks were built by Mack in the US and shipped in a knocked down form then assembled here. They were used for pulling 100 ton belly dumper trailers.

The one that was changed to allison trans as a trial wasnt very successful with retarder / heat problems.

Diffs and rear suspension look the same as your regular 44's on camelback but on steroids, twice the size.

Engines are Mack V8's. Ive been told they are an early version of the E9. 475hp

Its an early R cab. 24"wheels.

They are not for sale and have / are being wrecked for the diffs and rear suspension for some other 6x4 dumpers he has.

Barry

Barry

Hello, Thanks for the reply and info.

My R767 was originally built with a Maxitorque 5 speed behind the Cummins + a spicer aux box.

I would like to restore it back to its original condition.

Barry

Howdy, There are four of these in a yard in Western Australia.

All four have Mack V8 power. Three with quads and the other is allison auto.

All four have fifth wheels.

Enjoy.

Barry

Hello,

Im trying to find some information on Mack's 5 speed Maxitorque trans as used in the R series and need some help.

I Need to find a 5 speed Maxitorque O/D trans to put behind a Cummins.

I have no idea on what model trans to look for ?

And have no idea how to tell what im looking at if I do find something ?

What would be the model number for this trans and where would I find the numbers on the case ?

Please excuse my ignorance but I never had much to do with Mack and im struggling.

Any help appreciated.

Barry

Hello,

Can anyone help a new Mack man decipher the numbers on my Mack rears from the picture. The ratio 5.73 is cool but the rest of the numbers I don’t understand.

Im trying to find a correct parts diagram for this setup to see what parts are available.

Any help appreciated

Barry

Jeff,

Thats the coolest news Ive had for a long time.

Got to get busy and see if I can find a copy of the mag now.

Thankyou very much for this info. It makes alot of things on the truck alot clearer now.

Regards,

Barry

Howdy Jeffro,

You are the second person that has said about the Mack 5 speed main and the spicer aux in this truck. After another look last night it has definatly had an aux box at some stage as the center bearing crossmember thats in there now has been made up.

It used to run Darwin - Alice pulling fuel tankers from about 76 to 84 then spent the rest of its life in the Kimberleys pulling a float.

It was in one of the early truck and bus or early truckin life when it won best at show at the Brisbane truck show in 1976.

Thanks for the reply.

Barry

old girl

Hello,

Below is a pic of my new toy. 1974 R767RS .

Would anybody know what trans these had. It has a pair of cast Mack brackets aft of the main trans which to me look like aux trans mounts. Floor has a second stick hole thats been covered up. It currently has a Fuller RTO 12513 behind the Cummins.

Any comments appreciated.

Barry

Lets see what happens

Lets see what happens

Thankyou for the info.

Ducky698 tells me there is a set of Budd hubs he in Western Australia so I might have a go at the swap.

Barry

Hello All,

Can anyone tell me what needs to be changed to swap from Dayton wheels to Budd type on a 74 R700 ?

Is it a straight swap of hub and brake drum onto axles with the same bearings or is it a little more complicated.

Any help appreciated.
