The hand / park brake was inoperative on this unit, so I dropped the driveline, removed the drum and shoes with the linings worn and loose from the shoes. I sent them out for relining and when they came back it seemed that the linings that were installed were thinner ( actual lining 9/32" thick). I installed them and couldn't get them to adjust up and grab the drum. In the slack position I can fit a 9/32" drill bit between the linings and the drum. Does any one have a part number or specs on the Bendix park brake shoes? I'm thinking they should have at least 1/2" lining thickness when new.  

A couple of contact suggestions to move your mixer

Sid Kemp in Chicago, not too far from you has large a fleet of Old Macks. He brought quite a few to Lexington. They are in the construction business so your truck is right up their ally. You might contact them to see if they have any interest or can guide you to someone that would.

The National ReadyMix Concrete Association has a web site and publication. Perhaps one of their members would like a historical tribute truck to celebrate their brand. I don't think a non-member can access their web site but perhaps your local ready-mix dealer would be willing to guide you on this.

Looked your truck up. Made from 1960 to 1965. 110 total produced.  On the rears the ratios only get worse, 7's, 8's, and 9',s.

I was wrong on the engine. Looking at your photos you have the Thermodyne gas engine. Either the EN438  160 HP  or the EN464B at 170 HP.

Nice score. Looks like a super truck.  My Mack Salesman's book lists a B46S.  It has a EN 401 Magnadyne engine (flathead 6) with a SWD 56 bogie. This model aimed at the dumper/mixer market. Looks like the highest ratio for this set up is a 6.45, so even with the .85 ratio in high split with the TRQ 77 (baby quad) you wont have much road speed. I had a B42T with the same engine and trans and it ran super. It was a single axle and I swapped in a higher ratio carrier and was able to run 65 with ease. I too thought about swapping in a diesel but the truck was too nice to alter.

Thanks Glenn. That explains it.

Larry. Making one is my plan B. Already found the proper size and degree aluminum elbow with a bead rolled in one end. but perhaps Mike will have one. Thanks for looking Mike. 

Got a question. Have to pull the radiator on the G and have the core replaced. It only lasted 60 years darn...  The cab only tilts about 40 degrees so it isn't coming out from above. Does it come out the front after removing the bumper and the grill.  Can anybody confirm this?

Thx

h67st

Hope you get your H done by next spring and bring it to the BVH spring show. I'm looking forward to seeing it. I thoroughly enjoyed driving my H. It ran and drove well, the original seat was quite comfortable and with the vent open in front, not at all uncomfortable in warm weather while underway. Not so sure on the driving experience in this G. Its more like large Spam can on a truck frame. Reminds me of the White 1550's of the 60's and 70's. No creature comforts at all.

Wanted simple old schooll truck Like the sound of a non turbo engine

Thanks for all your comments. Got a call into Tom Pierce on this. Been friends with him since his “Big John” restoration. Also no maxi conversion possible without major changes as the RA91 axle has the chambers directly below and up against the springs. 

Needed for an H67 a TRD 67 or TRD 670 Trans.
