I got to take my winter season boss's son out in their manual trans oil delivery truck because he needed seat time and a fresh copilot to learn a few things from for his CDL skills test. Synchronized transmissions are junk, but at least he will be legal to drive manual transmissions! Wife just gave birth to my son a couple hours ago, I'll be sure to keep one of our 2 sticks in roadworthy condition for 18 years from now!

That's nothing. The rust by the 5th is just from the 5th wheel being moved to different positions and the axle housing looks a little scabby but everything else has paint and no rust stains. An axle housing can be replaced. Rusty frames are more worrisome. From the pics it's a good looking truck, I don't see anything I'd be scared of.

That's basically just a 2 stick with an airshift instead of the 2nd stick. Great trans for an old maxidyne, not great for an e7. 2 stick I learned on is a killer transmission though. Can't break it.

I can't stand my 8LL. It was abused before we got it. Sometimes when you come out of gear and you're in the neutral zone it's still in gear for another second or two. Sometimes it hangs up coming out of gear. Hasn't blown itself up yet though! Couldn't stand the 8LL in my cousins intertrashional dump years ago either. Had a U shift pattern instead of H, and it took a good bit of effort to get out of gear. And second to third was a bear with the U pattern. Drove a Pete with an 8LL and a 500hp cat, that shifted very nicely. And I owned a 400hp Mack tractor with a 10spd Eaton that shifted nicely, except it would grind the lo/hi range transition between 5th and 6th once in a while.

Measure another truck with same size tires from ground to top of rail. Set your truck to that and call it a day.

I want that T310M. Matches my 8LL in overdrive.

My mechanical e7-350 needs more than 6 gears, it's a dog at 40k-73,280 lbs on most of the hills here even with an 8LL. I'll keep the 8LL til it blows up, but we'll be building another truck in the next few years. Nice to know what options to look for.

I'm with Terry on the triple!

I always assumed the 2 stick Mack trans was the only multi reverse speed trans, apart from Lolo/low/high. What other Mack transmissions can you shift gears in reverse? How recent have these transmissions been produced? I run a concrete delivery company and multispeed reverse is King. My 8LL is junk, hangs up in gear for a second sometimes even when shifter is in neutral. 8ll is good 95% of shifts, other 5% it hangs up going in or out.

Should be under 12 tons?

Was going to say that looks like an Allan Myers truck, then I read the plaque!!

Aluminum frames wouldn't hold up to 1 year on Pennsylvania roads? Aluminum doesn't have a good enough fatigue cycle for our potholes? Still not sure what defines as a Hayward design. Longer hood? Too many tight twisty turns? Bridge laws here allow for more weight on a shorter wheelbase? Western hood is probably just an attempt at driver comfort and axle weight rating distribution? With allowance for longer engine? Maybe the Big 6 was gonna go out west but they canned it along with Hayward?

Because of potential. Not making money means the stock value could be undervalued. A tweak here and there and getting the right people into management can turn a money loser into a winner. Also, products that are so good they never fail or can be fixed by anyone tend to run manufacturers out of business, because then they have to sell lots of trucks to compensate for not selling parts. But many people can't afford new trucks and buy used. Apart from elephant pads and a thermostat and brakes and a couple hubs my 95 rd688s e7-350 hasn't needed a thing since we bought it in 2007. Had the valve covers off once to check valve adjustments and that's it. 19,007 hours on the motor. Mack/Volvo doesn't make money on that.

Answered my own question.

What is a Hayward Mack?

Is there anything Rob doesn't know how to do? 🤓

Doesnt look bad at all...

They're both single axles. I think he wants to restore one of them someday, but he owns an oil delivery company and growing propane company, don't know where these fit in his plans.

It's functionally about the same as a wheel loader with that face bucket. Only real difference is that instead of driving from the scoop to the dump it just rotates. Working weight is 210 tonnes, wonder how much weight per scoop....

Got you all a couple pictures while dropping off a sandblaster I borrowed from a friend. Not sure if they drive, every few years they're parked somewhere else on his property. One or both of them are gassers.

Prior to air dryers they used alcohol. Just drain tanks then suck some air system alcohol through the compressor intake before winter time.

You have a hand primer on it?

Pull your valve covers, maybe you have a bent exhaust valve not closing all the way. With engine running, apply pressure to each rocker and see if somebody isn't working right... A quick visual comparison can quickly rule out potential mechanical failures. A valve not closing would also let combustion continue in the exhaust pipe, which would be hotter than completed combustion. And it'd probably sound like an exhaust leak. Because it kinda is.

Is the 3M for the dash panels? What do you use as a new panel underneath the 3M? I have a few trucks that could benefit from new dash panels...

Probably worked in the woods, 2300 miles of off-road only. Maybe hauled logging equipment on site? I know nothing about logging.
