Motor Housing Cavity
With the pump in an upright position, remove the
pressure relief valve (29) on the top of the pump.
See Table 2 and add the recommended grade of
lubricant (Table E-3) to the motor cavity.
Maintain
the oil at this level
. Apply `Loctite Pipe Sealant
With Teflon No. 592' or equivalent sealant to the
threads of the relief valve (29). Reinstall and tighten
the valve.
Never attempt to fill the motor cavity
through the drain plug (7) opening. A vol
ume of air must be trapped above the mo
tor to permit thermal expansion of the mo
tor oil.
