Works like a champ until the clutch is oiled down from a leaky rear main. Ask me how I know. It's an aluminum piston that rides the counter shaft. No worries about noobs pushing the pedal too far.

@@itsstillkickin4630 surprisingly, ive only seen that twice. Both from the same company too. Pushed the pedal so hard, they dished the throughout bearing.

I'm not sure about the unloading height. Roading it's 14'2". Used it a lot for a year, but no ground to work the last two. One upgrade that was worth it's weight in gold was swapping the Holley carb for an Edelbrock

Did - about 5min later. Also fixed the valve cover leak and burnt brake line. Kind of what I do.

Not sure. I'll look next time I'm up at that farm

Truck is a 72 with only 50k on it so probably original

@@itsstillkickin4630 Look for an oval shape about 1"x3/8" with a 4 digit number in it. The first 2 are the week it was made and the second 2 are the last 2 of the year of manufacture.

I'm in Albin quite a bit 👍🏻

Yes, and a 6x4 has 24 total speeds. That's how its was done before the big power motors came along.

@@thekodiak77 Usually there's not so many usable gears, because some are almost the same ration as some else gears are. But ofcourse you can use all , but no reason for doing so.

That one just ticked over 60,000 miles. Still shifts stiff like a new truck.

@@itsstillkickin4630 That is awesome! Happy Motoring !~ ( I'd love to find an old B Mack now, fix up for show...

They did

No, but 2-2 is fine. First on the main box is left and down in that truck, so 2nd would be center and up. 2nd on the brownie is left and down.

Dina 531 has the gas engine in 1970.

My first boss had a 12 yard tandem International with a 345 gas and the same RT-613 trans. This was 25 years ago. I never got to drive it but they said it would pull.

@@allenbowick4716 it has to be very funny driving these trucks, like taking your pick Up to the super market and throwing 8 o 9 gears every block and using the air brake pedal every time you see a friend instead of the horn. Still dont understant why you should get a gas engine truck whit big trasmition if you could get a diesel engine in it. Thanks!!

They were more common than diesel in their day in that size truck. It pulls 30,000 in the box (about 50 gross) regularly. That's our standard load of potatoes. Sometimes quite a bit more if needed. You don't get the hard pull on 10% or steeper grades unless you're down in the bottom of "int" range (4-7th gear). Without the gears, that engine wouldn't be enough, but with enough gears, any engine is enough. I've driven straight 6 gas twin sticks - they'll haul quite a bit as well.

@@itsstillkickin4630 wow, i didn't know gas eniges were capable of that. But as you said its a matter of tons of gears. I wonder why those trucks wasn't equiped whit 453's, 471's, 6v53's Detroits or v378, v555 or v903 engines; they were very common in that era and i tend to think that they should be more eficient than any gas engine in therms of hp, torque and fuel consumption. Any wey thanks por Sharing

@@santopiantado1161 The 2 stroke detroit was an option, and quite frankly, didn't make any more HP - it also got much worse milage.

It's not in the clutch housing at all. It's not really a "Clutch brake" per se, but a countershaft brake. Same end result. There's an aluminum air piston that pushes against the countershaft and stops it.

@@itsstillkickin4630 any detail on this as looking to do with my 613

@@Hitman-ds1ei Look for a cover on the left side of the trans, not very big, has 4 bolts. If you take it off and find a round bore for a piston, that's it. You just need to supply air through the cover (1/8 line?) from the valve you mount on the shifter. All the parts are still available new. I had to replace that piston and valve last year.

I think it's about a 5:13 differential ratio

@@itsstillkickin4630 whats the meaning of those numbers, could you explain to me a little please!!

How many times the driveshaft turns compared to the number of times the axle turns. It would be 5.13 turns of the driveshaft to one turn of the axle. Gives the engine and transmission a torque advantage. Street cars usually have a "taller" ratio of around 2.73 or so.

@@itsstillkickin4630 thanks a lot, now i know what you are talking about. Í thought that in order to know if your truck has a larger or shorter "legs" was about the number of tooths betwen the pinion and the crown. Lets say, 7:37 (seven tooths on the pinion - 37 in the crown) very shorts legs in the flats but very strogn in hilly roads.
