@mrsmackpaul correct me if im work but what I understand the Econodyne was the most the 4v engines. I could be remembering wrong. I will do some more research on the pump and see if I can find somthing on HP/fuel ratings and let you guys know. Thanks for your help!

She's looking great now...love that shift knob...... 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

Are Volvo 3080801 and 3080802 old White parts?

This reminds me of working on a Drilling rig, trying to pull the third member, it would just not move at all ended up backing a rig up truck up to the front of the rig hooked the one inch cable to the yoke and slowly winched the cable got real tight and the third member shot out the axle housing had collapsed pinching the third member in the housing.

12,000 pound axle is kind of small for a tandem axle dump truck, will wear the kingpins out pretty quick. Also pretty weak springs for alot of weight on the steer axle. terry

@mrsmackpaul Econdyne but that i am unsure of. Econdyne was the first of the 4v from what I understand. I Apologize for my ignorance

1986 I believe assuming the engine has never been replaced. the intercooler is mounted to front side of the cooling package.

Would've been a Good dog to put a Moo Dawg Brew Tanker on and acouple Cheater Axles on it too!

I just purchased a1959 B67LT. The passenger side fuel tank does not have steps. It has a manufacture tag dated 1/58. Was this standard on some models at that time? Thanks

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

Well, I have been running the R model off and on when I can find the work, it has steadily been trickling in. I have been doing mostly hauling stone out of the quarry for driveways and such so far this winter. It's been a pretty fun year with the new truck, and good news is I have a pretty big job coming up for it. I've had to replace a few things, like a brake chamber and some lights. Had to fight through the cold and snow just to get her started up after cold soaking for a week while I was in Texas. But, it has beat the 9-5 redundancy I was used to and I'm enjoying the adventure. I hauled a load of rock today at probably 80 miles round trip and when I landed back at home, I noticed a drip from the passenger front wheel seal leaking down the backside of the hub. Yipee for me, shouldn't be too bad to do, just hope nothing is torn up. Anyways, this sent me down a path for finding a parts diagram or part numbers. So I referenced the original build sheet to find my axle. The truck has the FAW537C 12,000lb front axle. It got me thinking about the GVWR on my truck. It's rated for 48,860lbs. Referencing that sheet again, it says that the 10,860lbs listed under "tire and rim" is my gvwr for the front axle, of course because they are lowest rated components. So, my question is, was it the wheels or the tires that were at their limit at 10,860#? I think I have H/16 ply steer tires on at the moment that are rated for 6610 a piece. Am I right in thinking this bumps my GVWR up to 50,000 pounds if the limit was the original tires? And I'm sure there's a chance I might need to get it verified in some way too. I'd sure like to be able to haul a 14t load. It's all new to me, so I'll go back to looking for parts. 02.pdf

Sorry Paul should have gave that info right off the bat. 1986 Mack Superliner RW613 Mack E6 4V HP?? Assuming 350HP Mack T2090 9 speed mack 4.64 rears with Neway air ride

I have thumbed through it doesn't give me much on diffrent HP ratings. I have a feeling I can find more out in a pump book. I will get some info on the pump tomorrow and do some more research and let you know.

Yeah Those ag Tires usually don't have alot of Air in them and are super soft

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

Raining,cold day here in WNC . Got the shop warm and spent most of the day tying up some loose ends on the Superliner, it had a 15 speed Eaton from the factory when we got it , it started making a noise so we replaced it with a 18 speed Eaton a few years back, I changed the Decal just to look complete, installed and wired up a “ Easy Jake “ ( I have these on a few of my trucks) changed the shift knob , added some fog lights that I had laying around for years,, Just basically playing around with it.

All 6 out. Picked up the right oil pan from motor shop as they hot tanked it for me. I traded the big 54 qt model for this. Good to have friends in good places. I also picked up the radiator but it's dark and cold so I will get pics tomorrow. I want to slip it in the collar to make sure everything is just as it was and will fit when I go to assemble this pile of parts come spring. I can't see it being an issue as the upper and lower tanks and side brackets all have to fit together and if the core was not sized right then they would not have been able to solder it together. Will be stopping at Mack dealer next week to order the kit. Piece by piece.....

I thought I recognized that boobage on the poster!

Hard to believe what it bought! terry and not a real popular running gear

Thought it was Somerville or somewhere around there.

well thanks for that

I don't, but for the last few decades only worked on my own stuff, and I used gaskets, not RTV, so they just popped right out.

I had a question maybe one of you guys could answer. I just bought my soon to be father in law door dogs for his R model Mack project. I found some brand new ones but they have a smooth shaft stud instead of a threaded nut/stud like I was expecting. Is there a special way these install or am I better off taking a die to it and threading it that way? Thanks!
