AR1064 Diaphragm Kit
Diaphragm AR43303 includes all parts needed to replace diaphragms on the AR1064 pump. AR recommends changing diaphragms every 500 hours or three months, whichever comes first. If your oil has turned a milky color you may have broken diaphragms.
AR43303 Replaces 9910-KIT2480 and will rebuild the Hypro D1064 pump
When rebuilding the pump diaphragms follow all factory torque specifications. Accumulator diaphragm should be set to 20% of pump operating pressure. Replacing diaphragms will require new oil. Replace with 30 weight non-detergent.
