Dump truck 

I don't know if the one j hancock has there is the multi piece one where you cut the old out and install new one in pieces. if your replacement is a one piece one, you have to set dump box off, cut rear hinge off  remove rear crossmembers and loosen front ones spread frame and slide tandems out, then take it apart. It's a whole bunch of heavy work!!     terry:MackLogo:

The post Hancock left is the way to go time wise for a dump or mixer application by far!

Just got off the phone with a shop recommended by local mack dealership 

1 to 2 days most time 1 day 5/6 out the door.

Well looks like I have to hit the work hard to get it done

So did they give you a solid estimate?    terry:MackLogo:

Last summer I installed one of the multi piece Stengle Bros. pieces on a garbage, (rolloff) truck. If you can stand the price, it is the one to use citing what has been stated already. 

Not a hard job, but heavy.

You're guessing the rest needs to be replaced? Why? What's broken? Trunnion bar? Trunnion cross member between the frames? Trunnion tower?

Not enough info! Sounds like we might be telling you to do more than you replay need to!

The trunnion bar on our 1980 dm686sx broke years ago, got it off the ground and dropped old one out, new one in and we were good to go! You must have really stressed the truck if you broke the trunnion tower or cross member...

I would guess maybe the tower rotted out, they will rust out where the tower sides come down to the trunnion.    terry:MackLogo:

My trucks never see road salt, but it's hard to imagine the truck frame outlasting those towers due to rust.

We’ve accomplished some pretty miserable trunnion removals. Dealership only installed OEM.

If your willing to remove some members(or a pusher), pop one side lose on every member up to transmission, and manipulate the trunnion toward chassis center, and you have enough hydraulics, you’ll pop that sucker out with pintle plate and hinge in place.

www.diaglebrothers.com vends a member our dealership designed in conjunction with their fabricators. It’s a member that anchors the inner tower to the outside and inside of the frame rail with two additional flanges. Once installed you can’t lose a trunnion unless you find a way to shear a tube. Made for Quads and Michigan trains.
