• Adjustable high pressure relief valve.
• Pressure gauge.
• Bypass lever.

AR1636 Gearbox

The Annovi Reverberi AR1636 Gearbox attaches the Hypro D30 Diaphragm Pump to a 5.5 hp gas engine with a 3/4" keyed shaft. It also works on the Hypro D303 and D403 diaphragm pumps. The gearbox is commonly found on many lawn spraying systems manufactured by Rittenhouse. Replaces the discontinued Hypro 9910-KIT1640 Gearbox.

Use this gearbox with 90 weight gear oil found in many hardware and automotive stores. Be careful not to put too much oil in the gearbox. The dipstick for the gearbox has a ridge near the bottom of the stick, do not fill past the ridge. The o-ring is already installed in the gear box, feel inside the ridge.

This is a 6:1 gear reduction for attaching to a Honda or Briggs gas engine.

Note: This AR1636 Gearbox can also work with the D50, D503, and D813 diaphragm pump models, but it is mandatory that the pumps are operated at lower pressures that do not exceed the 5 hp gas engine compatibility.
