The Annovi Reverberi AR1636 Gearbox is used to attach an AR30-SP and AR403-SP 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 AR Diaphragm Pump models:
- AR30
- AR303
- AR40
- AR403
Since the AR1636 Gearbox is a replacement for the Hypro 9910-KIT1640 Gearbox, it can be used on the discontinued Hypro 9910-D30 and 9910-D403 Diaphragm Pumps.
