Viking Pump TSM615: In-line Gear Reducers - Manual (Page 2)

SECTION TSM 615 ISSUE I PAGE 2 OF 5
LUBRICATION
Gear units are oil-bath lubricated. For applications calling for
speed reducers with vertical shaft orientation, oil coverage
during operation would not be sufficient to ensure correct
lubrication of upper bearings, suitable life lubrication systems
must be used.
Speed reducer sizes 12 - 41 are supplied pre-filled with oil and
do not have oil filling or level plugs. These long-life lubricated
units (using synthetic oil) are capable of operating at an
ambient temperature range of -4°F (-20°C) to 122°F (50°C).
For temperatures below -4°F (-20°C), contact your authorized
distributor or Viking Technical Service.
Speed reducers sizes 51 - 100 require oil filling by the user.
Before start-up, fill with the correct quantity of oil using
Table 1. These quantities are approximate, use the sight
glass on the unit to fill accurately. When filled correctly, the
oil level should be in the center of the sight glass. Choose
the viscosity and type of oil from Table 2 that is appropriate
for the ambient temperature. Viking highly recommends the
use of synthetic oil as it maintains viscosity properties over a
broader temperature range, shear rates and time. In addition,
synthetic oils usually contain additives that prevent foaming
and rusting, such as Mobil SHC 600 series, Texaco Synlube
CLP series or equivalents. These speed reducers are supplied
with oil fill, level, and drain plugs.
Contact your authorized distributor or Viking Technical Service
for vertical or other mounting arrangements.

Periodic Oil Changes
Periodic oil changes are not required for sizes 12 - 41 as
they are lubricated for life with synthetic oil. The remaining
sizes 51 – 100 are designed for oil lubrication and have oil fill,
level, and drain plugs, see “Plug Locations”. Users should
replace the oil based on Table 3 and following the directions
in “Lubrication”.
CAUTION !
Sizes 12, 22, 32, 36, 41 are pre-filled with
synthetic lubricant when shipped and require
no additional lubricant. These sizes have
no oil filling or level plugs. Sizes 51 – 100
require filling with correct amount and type of
lubricant prior to use. Operating reducer
without the proper type and amount of
lubricant for even a short period of time may
cause damage.
STORAGE
Observe the following instructions to ensure correct storage of
products:
A) Do not store outdoors, in areas exposed to weather or with
excessive humidity.
B) Always place boards, wood, or other material between the
products and the floor. The gearbox should not have direct
contact with the floor.
C) For long term storage (over 60 days), all machined surfaces
such as flanges, shafts and couplings must be protected
with a suitable rust inhibiting product (Mobilarma 248 or
equivalent).
D) The following measures must be taken when products are
stored for a period exceeding 6 months:
• For life lubricated products, the machined areas must be
greased to prevent oxidation.
• In addition to above, products originally supplied without
oil must be positioned with the breather plug at the highest
point and filled with oil.
Before operating the speed reducer, restore the correct
quantity of oil.
Table 1
It must be emphasized that these quantities are only
indicative and users should check the correct level through
the sight glass.
