(7), which are shipped loose. The air vent
must be installed to prevent the gearbox
from overheating during operation.

The gearbox assembly was lubricated and
tested before it was shipped from the facto­
ry; however, the lubricant level must be
checked
before putting the pump into ser­
vice.

Change the lubricant in a new gearbox after an ini­
tial break‐in period of 24 hours, and before 100
hours of operation. The lubricant should be
changed while the pump is at operating tempera­
ture. Remove the gearbox drain plug to drain the
gearbox.

Add 2 ounces (0,1 liter) of Dow Corning `Molykote

r

M Gear Guard' to the gearbox, then top off with ap­
proximately 20 ounces (591 ml) of premium quali­
ty, multi‐purpose, extreme pressure gear lubricant
with an SAE rating per the ambient temperatures
shown below ‐ or until lubricant runs out of the oil

level hole. Always clean the drain plug thoroughly
before reinstalling it.

After the initial change, change the lubricant after
every 500 hours of operation or every six months,
whichever comes first. Change the oil more fre­
quently if the pump is operated continuously or in­
stalled in an environment with rapid temperature
change.

Monitor the condition of the bearing lubri­
cant regularly for evidence of rust or mois­
ture condensation. This is especially im­
portant in areas where variable hot and
cold temperatures are common.
