Found this from some Googling about May or may not help Paul

I assume the oil pickup is different on the bigger sump ? Might be worth looking into Paul

This maybe what your looking for CAS CARBIDE-SERIES BLUETOOTH RADIO CONVERSION : CIRCA 1960-1985 (MACK TRUCKS) https://www.retrosoundusa.com.au/index.php?l=product_detail&p=3518 Paul

Just watching this, we were calling them Econodyne in 86 Paul

I couldn't advise properly on that as Mack Australia offered a very different line of trucks than the U.S. I'm fairly certain the Econodyne arrived towards the end of the E6 in Australia Could still get Maxidyne and Thermodyne in the 4 valve Not even sure what the difference is between a Thermodyne and Econodyne apart from the name I only recall seeing Econodyne when the Valueliner arrived on the scene in Australia, thinking 86 onwards for some reason Paul

With it been a 9 speed I doubt it's a Maxidyne Not sure when the Econodyne arrived on the scene, I think it is pretty safe to assume that if it is intercooled from in front of the radiator it is either a 300 or a 350 Thermodyne or Econodyne Either are good motors and wont disappoint the user thats after a old fashioned mechanical motor with a hairy chest and a decent set of balls Paul

What year is it Assuming now it's either a Thermodyne or a Econodyne Tip turbine or chassis mounted intercooler ? I am assuming the inter cooler is in front of the radiator Paul

Im thinking you need to give us more details Whats the truck, body truck or prime mover (tractor) What transmission What model truck Paul

Plate looks like a virgin that has never been stamped Paul

Well I doubt it's stuck, putting all that force and not moving suggests something still isn't removed inside the diff center Not knowing what brand it is, could be a not so common brand, have come across axles with a big circlip on the spider gear end that has me puzzled for a while Paul

Great work, nearly there now Paul

Happy birthday for the other day Linda I completed another orbit around the sun on Monday Paul

OHS Mack with apparently a camel rescue ??? Paul

You can buy 20 thou over sleeves in Australia off the shelf So I reckon it won't be a drama in the U.S. as ours probably come from the same supplier If the link works in Yanky land you'll see STD, 6, 12 and 20 thou sleeves Cylinder Sleeve For Mack Engine E-6 2VH/4VH - MaxiTrucks https://share.google/H24bIClcGFfCC1rKZ Paul

I have gone through a few speedos and tachos, all genuine Mack, some last 20,000 kms some last and last I found the cable length had big result in how long they last A longer cable with not as sharp turns seems to last forever Well done on the 4000 miles Paul

Good job I guess it's time for another R model Paul

Iranian trucker Paul

Looking good, it will look different once the clear coat goes on Paul

I reckon it's cheap insurance on a good motor I got the R model done, it was crazy expensive, I think all Australian Macks of that era came with the biggest radiator you could get I can't remember the exact price, but it was over $5000 Australian Back then, with the exchange rate it was about $3600 US You probably felt the earth tremor when my jaw hit the ground But compared to the cost of a motor it is cheap Paul

Should be able to read it all ifbyou zoom in a bit Paul

Copied from Mack Muster Facelessbook page 🚛 This Week’s Fact, Countdown to the Mack Muster, 21–22 March 2026! As we gear up for the Mack Muster next March, here’s a look back at a key moment in Aussie Mack history. The very first two Australian R series field-evaluation units, the lighter-specced R403RS and the more premium R609RS, rolled out sharing the same fresh appearance, brand-new chassis and a noticeably larger cab. But their stand-out feature was something truly ahead of its time: a revolutionary one-piece fibreglass tilt bonnet. This new fibreglass design made engine access far easier than ever before. However, many long-time Mack customers were still big fans of the proven heavy-duty steel-sheeted bonnet and fender setup, similar to the B series. With such strong feedback from operators, MTA engineers soon introduced a steel-bonnet option for the R series. This rugged, tough-looking version quickly earned the nickname “Flintstone” thanks to its (stone age) strong appearance. More history, more trucks, and more stories just like this will be on show at the Mack Muster, 21–22 March 2026. Don’t miss it! 🚚💨

I'll just chuck these in here NMP
