R.E.D Posted February 26, 2022 Share Posted February 26, 2022 Assuming you have mack rears , it should be 28 spline ,1-1/2 " hole and 6inch spacing between clevis pin and center of s cam spline shaft.

mechohaulic Posted March 5, 2022 Share Posted March 5, 2022 auto slacks first came out , it was critical to have all matching. is it not necessary now? the slacks had a color coded tye wrap . miss match might have one adjusting faster than another. replaced one last week on trailer suspension = couldn't find a color code. correct spline and ctr distance.

According to law I was told at a bendix foundation class they must be the same brand across an axle. So even a haldex against a reproduction haldex can get you written up. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69294-auto-slack-adjuster/#findComment-491018 Share on other sites More sharing options...

Joey Mack Posted March 6, 2022 Share Posted March 6, 2022 yeah that seems like a stretch... hell, is there a law dog that would even know what they are looking at? as long as they are the same style and 'Length' positioned in the same holes, I dont see a problem........ and I too, tried to buy auto slacks for a steer axle last week. i gave them the part number on the slack adjuster, (Mack dealer)... they said, I cant help you, I need a VIN and need to see them.. I explained the truck was an '86 Superliner.

I haven't had any issues with this yet, but I've had such crap as them measuring the reflective tape on the mudflaps and writing it up as well as 1/2" thick oem legal length dump trailer mudflaps blowing too high. I also remember the first dot cop around that starting writing dump trucks up for body-up lights before most knew it was a law. The rest caught on pretty quick. Steer axle slacks can be tricky especially on a Mack with rotochambers and the offset arms.

Maybe soon they'll be gone. Just a week ago there was discussion about the new covid guidelines for masking and social distancing in the event of a nuclear attack. Then suddenly ahead of President Dementia's State of the Union address covid was eradicated. 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69294-auto-slack-adjuster/#findComment-491042 Share on other sites More sharing options...

Dammit!!! jojo you sure know how to make a guy feel old LOL . i was wrench pushing on the day of your birth. 😁😁 each generation guess sees changes . unfortunately the coming changes don't seem positive. remember trucks were way simpler then. there's more wires in one new "junk" then 5-6 B models had. i truly enjoy reading these forums ; just find it difficult to see how the trucks have become like cars with all the electronics. most accessories were able to be in house rebuilds. injection pumps could be tinkered with on limited scale. when factory stated a MB fire truck couldn't have a jake brake, little tinkering had one ,, NO vin number or computer needed. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69294-auto-slack-adjuster/#findComment-491061 Share on other sites More sharing options...

Can you guys believe that they are owners operators that work with me that don't know what setting the lash on the valves is? I asked him if he owned some feeler gauges and he looked at me like if I was asking him how to perform heart surgery. LOL.

Popular Post mechohaulic Posted March 8, 2022 Popular Post Share Posted March 8, 2022 valve lash !!!!! my last employer ; a major soda company Co-a Co-a had a fleet supervisor that questioned why the starter was so high up on the engine;; might have something to do with he was looking at the AC compressor. and he was serious think he was in his 30's. in charge of transportation. other side of coin;;; WAY back my foreman at Mack knew Macks and the mechanical world better then anyone; a little known secret was he couldn't read . I learned more and had the most respect till this day for him. had to read to him one day the instructions on a paint can. what a changing world. 4 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69294-auto-slack-adjuster/#findComment-491182 Share on other sites More sharing options...
