ok thats just hilarious,,,,progress?????haha....weather got to hot,,,after the second soaking,,,havent been out there,,,im starting to think i shoulda ordered that rebuilt one from florida,,,,i was expecting to have this cleaned up,in 2-3 weeks...looks like its going to be longer,,,,but thanks for inquiring paul...

Maybe 866?

No. R700 chassis has similar config to R600 chassis but of higher section and of thicker sheet (3/8"). F700 chassis has different shape of the front portion, actually its own specific shape as long as I could observe along other Mack models. Maybe CF firetrucks had similar rails IDK. At the same time if I'm not wrong F700 had the same (light) section of the rails at the rear as R600 - 9" tall and 1/4" thick. That's standard section for basic B-models and a few other Macks of the era. Worth to point out we talk about Eastern R's and F's. Western R700 (RS/RL700) like your truck have straight rails with constant section front to rear. I don't have specs for those frames, would be interesting to learn the sizes. There were also FS/FL (700?) produced at Hayward factory. Which also had straight frame rails, the most probably similar to what was used in RS/RL700.

They appear to be a impressive well optioned truck Air ride front axle and yet Kenworth still only offer springs in their front end on COE K220 Air ride front axles have been standard on interstate buses since the late 70's early 80's in Australia It would probably sell well out here Paul

That's funny, definitely!

So you sprayed and let it soak in really good, nearly a weeks worth of soaking Summer is about half done Winter is just around the corner, just letting you know that Anyway, I'm guessing the progress has been so great you haven't had time to stop and share So how is it coming along, anything to report ? Paul

And yet our close neighbors in NewZealand had a bigger range of Macks as some were Australian based and some fully imported from the U.S. RHD Seems to be no rhyme nor reason to how it all went Anyways, back the build Oh I think 675 was the biggest power output of the E9 offered in Australia Paul

ya id like to have it

Wow that MH is fantastic.Please tell me someone saved it.... Paul

lol i just yell out snacks,,,if i dont see mine,,,,we have coyotes,,,but they usually dont come around where theirs too many houses,,,unless they cant find enough prey,,,,in the rural areas ,,,they will hunt in neighborhoods,,,i alway keep my gates closed,,,but mrs mower tells me if they want your pets,they will leap a 6 ft fence

Odviously things are done differently down under! Paul! Couldn’t get 650 v8 here ever I would like to have seen one! With a vmac pump! Very interesting! We were able to at one point order the cam and turbo here through the Mack system we did two trucks up with the Aus turbo and cam with the pump jacked up they pulled like know body’s business!

duplex and triplex,,were very common here

And even before the Maxitorque box was around, pretty much everything had a quad box and very occasional duplex I have never seen or heard of triplex or simplex (think that was the name of Mack 5 speed) in Australia Paul

Im fairly certain 285 Maxidyne is a air to air intercooled tip turbine job A 300 Maxidyne is series air to air, so water cooling and tip turbine intercooled job A little more fuel and a more efficient intercooling and 300 Maxidyne was produced after 285 In the Thermodyne it was the same and 320 went to 350 hp We never had the range of motors, transmissions and backends etc that was available in the U.S. So I have never heard of a 315 or a 295 hp motor Even gear boxes 5, 6, 10 and 12 speed None of the other numbers you blokes mention Paul

And the garbage pex clamps!🙄

Hi, I'm not sure if this is the right forum for this and if not, I apologize in advance. I recently inherited my fathers 1925 Mack AC Bulldog 4 cylinder truck. It is currently on display in a museum where it has been well maintained. The museum would like to continue to display and is going to have an appraisal completed. My question is does anyone know what the value maybe or direct me to someone that could help?

Seconding this, we only use red 50/50 extended life in our shop, that's what Mack/Volvo specs with these trucks.

We've had a couple ETECH's with weak injector seals that let fuel mix with oil, if I remember correctly. Been a while since that happened. The only internal leaks we've seen were coolant and oil from a cracked liner. I'm struggling to imagine a cracked block on an ETECH mixing fuel and oil...

You say you checked, but I just want to say in case this helps someone else or might be your problem, but the most constant boost leak on the MP engines is the blue boots on the hot CAC pipe, the turbo-CAC pipe. Things go bad all the time.

It is, just fuel and timing is different. The "673" denotes a Thermodyne(multi gear trans) and the 675/676 was Maxidyne(5spd).

Yup, from what I have read.

That tube with the two sensors is called the EGR Mass Flow Tube/Assembly, using those terms with a parts person SHOULD get you the right part the first time.

Yeah, I've seen both before but neither is something you see on a regular basis, at least not around here. I was startled to say the least, and it was a good ways away out in the tall grass in the field. When I saw it had something in it's mouth the first thing I did was call for my dog, because they had been out in the yard just a few minutes before. They don't go outside the fence though. Sometimes I'll have Roman out with me but Mack doesn't go outside the fence unless he escapes, because he'll take off exploring. Then I have to rattle a potato chip bag to lure him back. 🤣

I saw a red fox in my yard a week ago, I left it be, as it was hunting rodents. I hear Coyotes often but rarely see them. Very afraid of humans and domesticated dog (which often bring a human with a gun). No mistaking a fox for a coyote, size and shape of the head are give-a-ways.
