Popular Post Timmyb Posted January 15, 2017 Popular Post Share Posted January 15, 2017 Doing some digging up of old stuff here but got lots of Mack brochures and spec sheets for Christmas. Found this interesting pic of what they call an A8 R897. It's a big Mack that's for sure. 1 4 Quote Link to comment Share on other sites More sharing options...

I'm curious what model it is, it's like cross between an RD800 and a DM800. As we've never had RD's or DM's here in AUS I'm guessing it would be R?800??? There's a fair chance it'll end with SX! cheers Mick stolen from the interweb, of course Hi I just came across this and would like to share that I started out my mechanic life working on this very fleet in the early 80s including No3 shown pic. They were also further modified in our workshops to cope with the harsh conditions of the Florentine valley in Tassie and constant operation at maximum and beyond load capacities. Cabs were reinforced to reduce cracking, bogie springs replaced with solid walking beams, stools plated inside. Shipped transmission replaced with 5 speed main and 4 speed Joey box. The standard chassis was unmodified triple channel. The 375hp V8s were strong although turbos were a regular casualty due to being run glowing hot over one particular hill pass called “the gap” along with the odd broken axle. A misguided engineer replaced the air over hydraulic drum brakes with full air disk brakes which was a bad move as the exposed rotors and pads got minced by dust, slush and rocks. We would be constantly changing pads where linings tore off backing plates . These things really had a tough life with typical loads around 70 ton, but not unusual to see 70-100 ton loads. The trailers were also customised with the standard pole (draw bar) replaced by hardwood logs fitted using chainsaw carpentry. They were definitely a beast of a truck and my time at the Maydena workshops and “Mack Shop” with the rest of the crew were some of the best of my working life. - Cheers Fred Edited December 19, 2019 by Mariner Typo 8 Quote Link to comment Share on other sites More sharing options...
Bullheaded Posted December 19, 2019 Share Posted December 19, 2019 Friend of mine had a winch tractor that looked just like that truck, except it was a DM800. But it was also yellow. Had an 8V71 Detroit in it and a two stick trans (can't remember what version) and it had the Mack 65,000 rears on Camelback. Quote Link to comment Share on other sites More sharing options...

Bullheaded Posted December 19, 2019 Share Posted December 19, 2019 I have two Bulldog magazines from 1982 I think (because they covered the introduction of the Canadian built RD800 and also featured the CL350ST's) and they have a lot of these steel hood R's in these issues. There was a bunch shipped to Sri Lanka for some big project. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post Bullheaded Posted December 20, 2019 Popular Post Share Posted December 20, 2019 My night shift snow haul got cancelled because they need the equipment to plow. So I dug up two of my old Canadian Bulldog mags. Sorry though....I took the easy way out and just took pics. But if you save them they can blow up to be easily read. And no I DON"T CARE if anyone uses my pics, LOL Got a couple other cool ones to show you but I'll start a separate thread. The DM's here were not out of the ordinary.....but it was those steel hood R's that caught my eye when I first saw this, because this was just before the RD800 was released. 2 1 Quote Link to comment Share on other sites More sharing options...

Mariner Posted December 20, 2019 Share Posted December 20, 2019 (edited) I’d be interested to know what powered those Sri Lankan dumpers, the snout/guards are shorter than the TBs we had. Edited December 20, 2019 by Mariner Typo Quote Link to comment Share on other sites More sharing options...
Bullheaded Posted December 20, 2019 Share Posted December 20, 2019 I would guess the yellow DM's are E6 Mack's. 1 Quote Link to comment Share on other sites More sharing options...

Basically a heavy duty versions of highway units. The main difference I noticed was the triple skin chassis, long wheel base and overwidth track (needed a permit/escort for highway) and of course the big Rad and steel snout. Everything beefed up for off road haulage at double that of allowable highway bogie loading (here anyway). I remember we also had a heavy float that dropped onto the log bolster for moving the madill long line cable loggers, dozers and excavators.

We've answered my question pretty well so now I'd like to see a DML800 too! Anyone got something? This is half the the fun of it for me, tracking down the odd, different models that Mack produced over the years. Cheers Mick p.s. are they anything to do with the detroit powered DM's seen on the net? What is a DML800? Quote Link to comment Share on other sites More sharing options...

You are correct....and yes....noisy thing the vacuum is.... We were stopped one morning by a tenant of the apartment building we were doing saying "that thing's awful loud for 7am" It was just idling...."this is gonna get worse before it gets better...." But, it's faster and cheaper than a crew of roofers. 1 Quote Lack of planning on your part does not constitute an emergency on my part.... Link to comment Share on other sites More sharing options...

Lol....twice I've been stopped for "Excessive Smoke" only to be sent on my way as the truck is old as dirt. We fixed the puff limiter shortly after that pic, but it still blows some and that's enough to garner some attention. It passes e-test every year with flying colours, and I keep a copy with the ownership, in case they want to see it...

Bullheaded Posted December 23, 2019 Share Posted December 23, 2019 I had my puff limiter plumbed into the air switch on my dash that was for the Mack 12 speed as my truck was converted to a 15 over Eaton before i got it. Two settings....driving through the scales compliant and full throttle response!! LOL. Before that when I was driving multiple company trucks I always had a pile of roofing nails in my tool box. They plug those air lines quite nicely. LOL. Quote Link to comment Share on other sites More sharing options...
