excessive wear, pitting or damage. Also see heading “Cleaning and
Inspection Guidelines” on page 70.

Installation
(See Figure 6-3: “Typical RSD Gearbox Removal,” on page 76.)
1. Review preceding sections “Before You Begin...,” on page 67. Also
see WARNING ! note found on page 68.
2. Install new gaskets to the seating surfaces of the pump head and the
gearbox housing. Apply a light coat of grease to the gasket to hold it
in place.
3. Make sure the pump gear and spacer are properly installed, with the
raised edge of the gear facing away from the impeller.
IMPORTANT !
MAKE SURE THE PUMP SHAFT SPACER (1/2” / 13 MM) IS INSTALLED ON THE

“TYPICAL RSD GEARBOX REMOVAL,” ON PAGE 76.)
4. With the gearbox adequately supported, lift it into place and carefully
slide the assembly onto the pump shaft assembly and outer bearing,
assuring the input gear and pump gear properly mesh.
Apply a coating of Loctite, then insert three (3) 1/2”-13 screws through
the pump housing to help hold the gearbox in place. Tighten screws
hand tight.
5. Apply a coating of Loctite, then insert the remaining 7/16”-14 screws
through the pump housing, gearbox and gasket. Tighten all screws in
a criss-cross fashion to ensure an EVEN seal and torque to 37 ft.-lbs.
