pmolitor Posted August 22, 2013 Share Posted August 22, 2013 anyone know where to get an air shift to engage the pto on a mack 6 speed trans? I installed my air ride cab and my levers to engage the pto and the vax don't work right now.

David Posted August 22, 2013 Share Posted August 22, 2013 I've had two six speeds with Mack PTO's. Both had a pneumatic cylinder on fabricated brackets to move the mechanical lever.

jakebrake86 Posted August 22, 2013 Share Posted August 22, 2013 A Mack PTO? I never knew such an animal existed. I take it they don't make them anymore? Were they direct mount or shaft style?

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.

pmolitor Posted August 22, 2013 Author Share Posted August 22, 2013 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.

Were they direct mount or shaft style?Instead of mounting to the side of the transmission they mounted to the back on the bottom counter shaft. 1 Quote Matt Link to comment https://www.bigmacktrucks.com/topic/32412-air-shift-pto/#findComment-201091 Share on other sites More sharing options...

thomastractorsvc Posted August 24, 2013 Share Posted August 24, 2013 yes that's what I am looking for, yours hooks to the back of the transmission? I was talking with a guy the other day and he said he had one that bolted to the trans but was unsure of the gear if it would match. Quote Robert"I reject your reality and substitute my own."

David Posted August 24, 2013 Share Posted August 24, 2013 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. Quote Link to comment https://www.bigmacktrucks.com/topic/32412-air-shift-pto/#findComment-201484 Share on other sites More sharing options...
pmolitor Posted August 24, 2013 Author Share Posted August 24, 2013 the only way to spread nice with the side mount was to raise the box two stages and hope tge tailgate would unlatch with the load against it. I much orefer my current set up even without the air shift.

Lmackattack Posted August 24, 2013 Share Posted August 24, 2013 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...

pmolitor Posted November 27, 2013 Author Share Posted November 27, 2013 still trying to find the air cylinder to engage the pto. might have to go with cables. the levers with solid rods are not liking the air ride cab addition.

MACKPARTS603 Posted November 27, 2013 Share Posted November 27, 2013 THERE WERE 2 DIFFERENT AIR SHIFT SETUPS DEPENDING IF YOU HAD THE SMALL 51% PTO OR THE LARGER 75 OR 90 % PTOS. I BELEIVE MOST OF THE PARTS ARE STLL AVAILABLE, JUST NEED TO KNOW WHAT PTO YOU HAVE. THERE SHOULD BE A CASTING NUMBER ON THE MAIN PTO HOUSING Quote Link to comment https://www.bigmacktrucks.com/topic/32412-air-shift-pto/#findComment-218724 Share on other sites More sharing options...
MACKPARTS603 Posted November 27, 2013 Share Posted November 27, 2013 I SOLD A LOT OF MACK REAR MOUNT PTO'S IN THE 80'S. I JUST CHECKED THE MACK DEPOTS AND THE PARTS FOR THE LARGER PTO'S ARE STILL AVAILABLE Quote Link to comment https://www.bigmacktrucks.com/topic/32412-air-shift-pto/#findComment-218726 Share on other sites More sharing options...

gearhead204 Posted November 28, 2013 Share Posted November 28, 2013 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.
