Overview

Annovi Reverberi AR1636 Gearbox attaches an AR30, AR403, or Hypro D30 and D403 Diaphragm Pump to a 5.5 HP gas engine with 3/4" keyed shaft. Replaces the discontinued Hypro 9910-KIT1640.

Product Description

The Annovi Reverberi AR1636 Gearbox is used to attach a Hypro D30, D403, or AR30 and AR403 Diaphragm Pump to a 5.5 HP gas engine with a 3/4" (19 mm) keyed shaft. This gearbox is found on many lawn spray systems manufactured by Rittenhouse.

Use this gearbox with 90 weight gear oil, which can be 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. It can be used with the following Hypro Diaphragm Pump models:

  • 9910-D30
  • 9910-D303
  • 9910-D403

Note: The AR1636 Gearbox can also work with the Annovi Reverberi AR30-SP, AR40-SP, and AR403-SP Diaphragm Pumps. The gearbox is also compatible with the Hypro D50, D503, and D813 Diaphragm Pumps, but it is mandatory that the pumps are operated at lower pressures that do not exceed the 5 HP gas engine compatibility.
