INSTALLATION
LUBRICATION
Combination TIGEAR reducers can be installed by either
using the drilled and tapped holes in the bottom of the
gearcase or by attaching a bolt-on foot kit. The mounting
surface must be flat or breakage may result when mounting
bolts are tightened. Use steel shims as required to assure
that the gearbox is sitting solidly on all four bolting points
and is properly aligned.
On hollow shaft units the ideal position of the tie rod arm is
at right angles to a line between the point of attachment of
the torque arm to the reducer and the centerline of the output shaft. This angle may vary up to 30 in either direction.
CAUTION: Exceeding the 30 variance of the tie rod could
result in excessive reaction load and equipment damage. It
is good practice to position the rod assembly such that it
will be loaded in tension during operation of the reducer.
Viewing the output shaft from the K-1 mounting position, a
clockwise rotation of the input shaft will cause a clockwise
rotation of the reducer about the output shaft. Proper positioning of the tie rod assembly will prevent the components
from being loaded in compression.
The DODGE Combination TIGEAR reducer incorporates
the unique RELIALUBE system which eliminates the
lengthy preparation normally required to put a reducer into
service. TIGEAR Combination reducers are factory filled
with Mobil SHC634 for S-1, K-1, and L-1 mounting positions. Any approved mounting position may be specified
upon order entry and additional lube, if required, will be
added at no additional charge. S2, S4, K2, K4, L2 and L4
mounting positions also require the addition of grease fittings for upper bearing lubrication and will be included at
no additional charge if ordered through factory. Note: Failure to follow these instructions will void warranty.
The chart below provides two methods for verifying the
reducer has the correct amount of oil. The oil can be measured by volume or by checking dimension “A”. Dimension
“A” is measured with a dipstick inserted into the tapped fill
hole from the machined top of the gearcase to the oil level
with the gearbox set level on the ground.

LUBRICANT OPTIONS
FOOD GRADE LUBRICANT
Engineering
Chevron FM460X lubricant serves the needs of food processing applications which need a non-contaminating gear
oil. Chevron FM460X carries USDA Class AA and H1
approvals. Use of this lubricant can reduce the potential
damage to food caused by oil seeping through worn-out
shaft seals.
LOW TEMPERATURE LUBRICANT
System-1
The standard lubricant provided with TIGEAR reducers
covers an operating ambient temperature range from
-10 F to +100 F. For ambient operating conditions above
+100 F contact DODGE Application Engineering. To apply
TIGEAR reducers in applications from -10o F to -30 F,
specify Mobil SHC-629 lubricant.

The Combination TIGEAR reducer requires no periodic
maintenance. However, DODGE recommends occasional
visual inspections to check for hardware security, leakage,
and general overall condition. In extremely dirty environments, heavy accumulation of dirt can cause overheating.
An occasional wash down or wipe-off will assure the long
life of the equipment.

When ambient temperatures exceed 100F, care should be
taken not to exceed a 200F sump temperature during unit
operation. These conditions could require the application
of a larger reducer. Units which operate in ambient temperatures below -10F may be accommodated on factory
orders by lower viscosity Mobil SHC 600 series products.
The continuous rated input horsepower shown on the
reducer nameplate is for a service factor of 1.0 at an input
speed of 1750 rpm. Before placing the reducer into service, check the nameplate to confirm that its horsepower
rating is consistent with the motor horsepower and desired
service factor.
On hollow shaft units, consideration should be given to the
design of the driven shaft on which the reducer is mounted.
Shafting material and size should be capable of carrying
loads from the reducer weight, transmitted torque, and tie
rod reaction force.

NOTE: Shaded units indicate mounting positions not
recommended. Use of product in positions not
recommended negates time-in-use warranty.
