1970 RS763LT

[Quickfarms]

I bought another Mack on Saturday 

it’s a little rough and has been sitting since 2007 

[Brocky]

Sharp truck!! Is that Osborn on the door?? From Wyoming??? They are good Mack People..

[mowerman]

Excellent it doesn’t look bad at all … Bob

[Quickfarms]

It looks like “O & SONS”

the truck has been in Southern California for at least 25 years

the interior has had animals living inside so it will be gutted

i need to deal with the seized throttle pedal and brake pedal.

the clutch feels real stiff

The ignition switch is out and there are several air valves laying in the cab and one is missing 

the instrument panel bezel is missing, the battery box covers are not on the truck

it will need a new drivers door 

it has a NTC335, 13 speed, 4.10 gears and 24.5 wheels

Cool dog! Plenty of potential. Congrats on the purchase!

Early Western R700 with steel dash and a single axle seems as a quite rare combo. At least for the East coast and it doesn't even worth to mention my neighbourhood.

A single axle is very common in Calif pulling double tankers and dump trlrs.

Looks like good Mack bones to work with

You probably mean bottom dump trailers.

You also see a lot of them hauling hay and in the ag sector not to mention LTL

[Quickfarms]

And it even has an air ride cab.

it will be a bunch of work to get it back on the road.

Brocky, it's an interesting fact. By my observations Western RS/RL700 with a single axle was as rare beast as I once was going to post a thread with a question of their very existance. But probably here on the forum we have more folks over East coast than the West so Western models were discussed less. On the other hand I remember relatively many Western RS600 showed out. And I belive no more than 2 or 3 pics of RS700 single axles were saved on my hard disk at all.

It is tentatively scheduled to be recovered on June 4 and the tractor will be a Mack B model

I stand corrected on the bottom dump VS end dump trailers.. I also thought most of the hay haulers used cabovers to gain more trailer length as hay is a lighter cargo. I am an east coaster who has only run Calif occasionally!! And have not been out there in 11 years

Did 335s have an intercooler ?

This engine has one

A 335 did not have a aftercooler but many installed them in later years.

[Mark T]

Then that's likely converted to a 350.   Which in my opinion makes it an even cooler truck 

[Quickfarms]

A 350, great 

I need more power so I am not climbing the passes in the slow lane.

I used to run with the military vehicle group but got kicked out because I drove to fast and all I did was fix everything so it was factory new so I could cruise at a comfortable speed.

at least the ATHS guys travel at 55+ in CA

A Small Cam in good shape also sounds fantastic. Not just the exhaust. The engine itself has a certain distinctive sound. 

[mowerman]

There’s a lot there to work with it looks like one I almost bought 40 years  ago set up the same way San Fernando valley I don’t remember why I passed can’t remember but I was definitely interested good luck with it partner nice catch… bob

[Quickfarms]

I worked on the truck today getting it ready to move to my place next weekend.

I aired up the tires and tried to charge the air system but the foot valve has a huge air leak so I had to cage the brakes and they were a little stubborn from sitting since 2007.

I will need to replace the foot valve and probably also the pedal since it is seized, as is the throttle pedal.

does anyone have the Mack part numbers? I suspect the throttle is Mack specific and the foot valve and pedal may be Bendix

 

 

[Brocky]

That is a REAL sharp Truck!!! Keep us posted on your progress..

[mowerman]

California  Length laws used to require cab overs in alotta applications … bob 

[Freightrain]

If the throttle is anything like a B, you might be able to salvage it.  Remove pedal, some heat might break the pin loose?  If not drill it and replace pin?  Worth a shot if the pedal itself isn't worn paper thin and need replaced. 

Watts has both pedal assemblies.
