1967 Mack R 685 torque rods

Recommended Posts

What are options to replace the old style rods or can you still get them?  I haven't called Mack yet about them just putting together a list of stuff that the truck needs.

Good I didn't know what I would have for options.  I checked on the trunion bushings as I am going to rebuild the spring packs and I figured since I was going to have all that stuff loose I want to change them

A couple have the plugs welded up and the are loose so figure they are probably need to be replaced

They look like 1RY312 series torque rods. When you contacted Watts Mack at 1-888-304-6225 with your model and serial number about new studs, seats, springs and 95RU32 rubber boots, what did they say?

Using your model and serial number, Watts can reference your truck's 3QK rear suspension arrangement and see the torque rod's component break down.

The truck pulls up in the Mack system but everything but the trunion bushings is NLA.

And the serviceable 1RY torque rods don't supercede to a non-serviceable torque rod, per the current Volvo Group Mack brand parts system.

Something like the TR20005, TR20009 or TR21014? ..................http://www.atrobushing.com/category/truck-torque-rod/

I have got them here from weldon supply and they are two parts that use a tube that you slide the ends up in and weld to the length you need.

Are the axle mounts tapered like new ones or are they straight?  I tried Stengel and they asked me that question.  I know on the other trucks that I have done the torque rod ends were tapered not sure how they would work if the ones I have are not tapered.

They are tapered studs. I would think, from that link, once you confirm the stud size having removed them, they can help you.

I did find on PAI site a rebuild kit for the ball socket.  If the plugs on mine weren't welded I would probably try that route first as I am sure the PAI kit would be less than a complete torque rod kit.

If you cut the welds off you will too probably fix them with no parts needed.
