Superdog Posted September 11, 2016 Share Posted September 11, 2016 I don't know what the proper Mack # is for it,but I've always heard it called the 3 spring Taperleaf suspension. Dad had an early version of it on his '80 Cruiseliner,they used 4 large bolts instead of U bolts,kept breaking the washers under the head of the bolts. Lightweight and rode better than our camelbacks . Quote Link to comment Share on other sites More sharing options...

66rmack Posted September 11, 2016 Author Share Posted September 11, 2016 Thank you good sir's. So it might be best to leave it there on a truck that is more play than work. The trunion is cracked and the boss got a cut off with a hd one and 44k camelbacks. We were going to just swap the whole set up onto this truck but if the taperleaf is a better ride then we might just swap the trunion and reuse the taperleaf.

I have seen alot of trunnions welded or plated to repair them. Quote Link to comment Share on other sites More sharing options...
blackdog2 Posted September 12, 2016 Share Posted September 12, 2016 We had bad experience with them so did other gas company's with broken leafs Amoco had a spring brake and catapult the truck over with trailer and alignment problems with eccentric anchor pins we kept them on T.B.A trailers .

It's a play truck more or less but we have a good trunion so we may as well replace it. Quote Link to comment Share on other sites More sharing options...

Maybe we will just swap it over to the trusty camelbacks and not worry about the taperleaf. With a air ride cab the ride shouldn't be too bad?

terry Posted September 12, 2016 Share Posted September 12, 2016 A 44.000 camelback is going to be ALOT rougher ride than that taperleaf. terry 2 Quote Link to comment Share on other sites More sharing options...

The truck is in the works to be a parade/back up hauler only for when he goes out. I would just hate to have problems with the taper leaf.
