air shift pto


Recommended Posts

I have the cab side. I need the air shifter that goes on the pto itself. it is an actual Mack pto. the volvo guys st mack just stare at me when I tell them it's a mack pto.

Go ask em for parts for an E9 or a trtxl1070, they look at you like your a Martian. I like asking them then letting em freak out a minute then I give em a p/n and they can't believe it exists.

they just laugh at me and tell me I need to get a newer truck. I look into their shop at all the newer trucks and tell them I don't have enough money for payments and repairs. come to think of it, I don't think ive ever seen a R model in their shop.

David, that is what I am trying to find.

The side mounts are ok for a wet line. The rear mount Mack PTO was designed for dump trucks where spreading was necessary. With the side mounts you must have the main stick in gear to run the pto and you can never get the speed of the truck to match the lift speed of the body for spreading. The rear mounts run without the stick in gear so you can choose any gear for spreading. They came in three ratios. Somewhere around 77, 99, and 124% of engine speed and were (are) expensive. About $2500 new and $1000 to $1500 used.

I have the mack rear mount pto for my 6 speed...The Mack pto part numbers were in some of the service books that mack made for the service dept. it had info for everything from orings to internal parts ....

IMHO the rear mount is the only way to go on the 6 speed or 12 speed... The rd I drive now has a side mount and it sucks...too much bs to operate for what it should be...

the t1070 used a small air slave cylinder about 1 1/2 x 4 if memory serves me and a air switch similar to a power divider sw.had a93 rd 688 with this set up. you would just have to match the throw of the cyl. to the cable or linkage arm and drill a hole in the arm and fab a bracket to anchor it to.

where do you get small air cylinders? I can fab tbr brackets no problem. I have all the controls.

Ebay. Search all categories for pneumatic cylinder. You'll find about 150.
