Ben,

Scania and Mack go as far back as the 40's or 50's. Mack acquired the rights to use the open combustion chamber design from Scania for use in the 673 verses the Lanova pre-combustion chamber design of the 672. Now as for the V8 Scania might have influenced Mack or vice versa, not sure. But the two engines have always been very different in the fact that Scania uses eight individual cylinder heads versus Mack's four. The 865/866 evolved from the 864 just like the 676 Maxidyne evolved from the 673. They are very similar in design. Scania kept the 14 liter until about 1990 or so until they switched to the 16 liter with the new Streamliner cab and bumped the power beyond the 14's 500HP. Mack switch to 16 liters at the end of the 70s with the 400HP ENDT1000 later renamed to the E9.

Its a shame Mack did not push the V8 more and they should have bumped the power like they did in Europe (565 HP) and Australia (610 HP. They could have then gave CAT and Cummins a run for their money but emissions were their downfall. I guess the engineering team wasnt up to snuff. Sad really when you think of how powerful the 237 was for its time (and in a way still is). Mack was really a leader in engine technology at one point.

ThaddeusW,

I heard one of the meanest sounding EA9-610 V8 engines which was in an Australian Titan a few weeks ago - OD Transport has a big fleet of V8 powered Macks and Scanias anywhere in Australia.... even the V8 Scanias sound mean! Followed a Euro IV SCR R620 to town last Sunday my time - not even a puff of black smoke from the exhaust!

Joe

Hi Bulldoggin',

THanks for the welcome.... that RD686 you have is a nice truck!

Do you know much about the Maxidyne constant-power diesel engines - or is Barry the man I need to speak to??? I need to know a few things on them.....

Joe

Howdy all,

I forgot to introduce myself when I first joined so I'm doing it now!

My name is Joe Hupp (both real and user (for this forum)) and I live in Mack Central (not!!), Dubbo, NSW Australia... most truck owners/operators actually own at least one in their fleets!

I'm just here to learn a bit about the old R-600 "Flintstone" model that was market in Australia from 1966 - 1970.... from what I have read somewhere, there were more than 2000 R-Models (across the entire life of the model) sold in Australia!

I'm about to buy a "Flinty" tow truck to restore - but the gear is coming off the back and the remainder of the body is staying put! If anyone knows someone out there looking for a couple of fairly heavy rated hydraulic rams, let me know after I put them up for sale (if I can - can I put things up for sale here???) on this site! Buyer must be in Australia (or willing to travel to Australia) and be willing to come over and pick them up otherwise there will be a fairly light surcharge put onto the price to cover wrapping them and readying them for dispatch!

Any information on the R-600 "Flintstone" would be much appreciated and can be emailed to me - please PM me for my email address! I have also attached a couple of pictures of said R-600 "Flintstone" for reference - please feel free to let me know what you think!

Thanks in advance,

Joe Hupp

Hey MackMadDaz,

You have yourself a great bunch of mates here! Like you, I have a really bad affliction to the Mack brand since I went for a drive in a 1994 CHR688RST ValueLiner with the V-Mac EA7-375 - that's where my nasty affliction with Mack came to me!

I am in the process of buying a R-600 Flintstone - visit http://www.bigmacktrucks.com/index.php?aut...view&id=103 to see her!

Joe

Hi guys,

Can you guys please tell me if this is based on the Australian Titan??? It most certainly looks like the Aussie Titan but I do stand to be corrected....

Joe

The front fenders if not available or salvageable will be expensive. I also envision quite a bit of expense to be incurred if following through on your stated plan with this unit. This is especially true if you do not have the spare parts in current inventory.

As far as rust: With a mechanics inspection mirror and flashlight look into both of the rear cab corners at lower points. Also above the headliner across the front, sides, and rear of the cab for rust and deterioration where the roof, cab outer, and cab inner panels are spot fastened together. These are very commom rust areas.

The doors are very straight forward. Usually if you can see rust on the outer side, it is much worse on the inner structure. It also appears the cab and front end are "leaning" towards the driver's side on that chassis. This could be as little as cab mouting insolators being bad, or rust in the mounting strutures which would be much worse.

Good luck with your project!

Rob

Rob,

I'm tending to think this photo doesn't show the truck in it's true style - the lean could be due to the camber of the road.... I'm not questioning your knowledge here but there's a reason why!

Joe

thank you Rob

Hi Rob and all who have posted here,

Just a quick one to say I haven't dropped off the perch - I've been too busy to come in and check out things here!

I have to say that I have the old Mack bug and am in the process of purchasing a R685RST "Flintstone" (this is what Mack Trucks Australia called the butterfly hood!) - I have decided to restore her to look like a replica of a later Brambles Heavy Haulage R-600/R-700. She has a 6-71 Detroit Diesel 2 stroke, a 13 speed RoadRanger and a single drive axle at the moment - am looking at going to the original 237hp Maxidyne, bogie (tandem) drive and twin stick transmission (quite possibly a Quadruplex and maybe not!!!). The cab, bonnet and guards are all steel so that helps a fair bit with stuff I need to do!!!

Also, one question:

Is there anything I need to look at, eg. rust in the doors, etc, should I want to buy this truck??

TIA,

Joe

PS: I have included a picture of the old girl in her current state! Feel free to let me know where problems do lie with the job!

Barry,

Is there any way of getting the newsletter sent to member's inboxes instead of having to download it from the forums? I would certainly like to know the ins and outs of Mack in America - I might even start me a newsletter for you guys to learn the ins and outs of Mack Trucks Australia!

Joe Hupp

PS: The newsletter is really good, mate!
