What's On Your Tanker #50 - Rear Dump Retrofits
By President Mark Davis

Nothing overly exciting hear - unless of course it doesn't work. We spoke about this issue before, when choosing to retrofit a rear dump valve/chute with a swiveling version, make sure that new chute will clear the top of your local dump tank frames. Remember that there is no standard on the height of a dump tank and there is no standard on the location of a dump chute. Many dump tanks come with a 29-inch height however, so make sure that your new swivel chute will clear that height. A.H. Stock's newer version of the Newton swivel provides greater clearance opportunity when retrofitting an older valve. The swiveling chute's rectangular design is more forgiving when trying to retrofit an older tanker.
