Installation
LUBRICATION
Every booster from Tuthill Vacuum & Blower
Systems is factory-tested, oil-drained, and shipped
dry to its installation point. Fill both independent oil
reservoirs to the proper level before operation. Oil
reservoirs are under the vacuum.
Shaft bearings at the gear end of the booster are
splash-lubricated by one or both gears dipping
into an oil reservoir formed in the gear end plate
and cover. Shaft bearings at the drive end of
the booster are lubricated by a slinger assembly
dipping into an oil reservoir. Before starting the
booster, fill the oil sumps as described in
Filling
Procedure on page 14
.
Add oil to the booster in the quantity listed in
Table
4-1 – Specifications on page 8
. Make sure oil
level is maintained within the notched area of the
sight glass.
See Figure 5-2
. Lower drive boosters
have “bull’s eye” type oil level gauges. Maintain oil
levels at the center of the glass.
WARNING
!
Never attempt to change or add lubrication
while the booster is running. Failure to heed this
warning could result in damage to the equipment
or personal injury. Oil must be checked when the
booster is NOT running.
WARNING
!
Properly dispose of the spent lubricants. Refer
to the manufacturer of the lubricant and any
regulations to assure proper and safe disposal.
WARNING
!
Do not start the booster until you are sure oil
has been put in the gear housing and rear
cover. Operation of the booster without proper
lubrication will cause the booster to fail and void
the warranty.
Assure oil is compatible with copper/yellow
metals (if equipped with cooling coils).
See Table 4-1 – Specifications on page 8
for oil capacities.

See Recommended Lubricants for Tuthill
Blower and vacuum boosters on page 33
for

3. Verify oil level is at proper level in both gear
end and drive end sight glasses.
4. Replace the fill plugs or breathers that were
removed in step 1.
