Popular Post JoeH Posted 7 hours ago Popular Post Share Posted 7 hours ago Title says it. 1988 RD690ST project. Truck needs very little, it was a Locust Ridge H&K truck we bought a number of years ago. Cab was green when we got it, we painted it white and its been sitting long enough to grow some... patina. They put new frame rails in it and im guessing rebuilt the engine not too long before we got it because you touch the key and it fires up and perks along nicely. EM6-300L with a 7 speed Mack transmission. Currently were working on renovating one of our old mixers to for this truck. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76459-1988-rd690st-project/ Share on other sites More sharing options...

JoeH Posted 6 hours ago Author Share Posted 6 hours ago Single stick, i wish it was a twin stick. Multi speed reverse is great for our application. This mixer gets a 2 section hydraulic pump running off a pto on the rear of one of the countershafts. Its tucked in real neatly between the driveshaft and the left frame rail's lower flange. Hydraulic tank goes on the left side of the mixer, and 2 suction lines will loop around over top of the left frame rail into the top of the pump, while the two pressure lines will come out the bottom of the pump and come under the frame rails and back up to run along the left side of the mixer to the control valves at the back.
