Instruction Manual
3.4.4 Assembly of Gear cage into
Pump Housing
Before assembly, several of the parts may need
special preparation.
The Journal Nut threads (on nut and housing),
Crankpin and Crankpin Shoulder, Worm Shaft,
Crank threads, Crank Nut, and if bearings or oil
seals are removed the outside of bearings and
seals and inside of mating housing surfaces must
be thoroughly cleaned of oil and foreign matter.
This will require scraping of parts to remove
original film of LOCTITE
TM
and use of solvent for
degreasing.
DO NOT IMMERSE SEALS IN
SOLVENT AS THIS MAY CAUSE
SEVERE SWELLING OF SEAL MATERIAL.
The following special tools and equipment
are required: MILROYAL

press in Seal until it is firmly seated in the
bottom of its recess.
b. The motor-side Shaft Bearing should
be pressed into its recess with grade

procedure should be followed for installing
the other bearing into the Journal Nut.
c. After the bearings are installed, lightly
coat the outside of Shaft Oil Seals with
