0BIntroduction
Taconite seals may be used in high dust operating environments. They use a grease purging system to prevent outside contaminants
from entering the speed reducer/gearmotor. Figure 1 below details the taconite seal assembly as utilized in the 4-Series Bevel
Buddybox.

1BProcedure
Please follow these instructions to maintain lubrication of the Taconite Seal system:
a. Unless otherwise specified, the Taconite output seals are each packed with NLGI #2 EP mineral grease prior to unit
shipment from the factory location.
b. Grease does not need to be added to the seals prior to unit start-up.
c. Add grease to the seals according to the guidelines indicated in Table 1. Refer to Table 2 for recommended greases.
Table 1: Lubrication Cycle
Output Shaft RPM Hours of Operation
>200 5,000
Please note that a highly contaminated environment may require a more frequent lubrication cycle.
d. If the unit will UnotUbe operated for a period greater than 6 months, apply a thin layer of grease to the outside surface of the
seals to prevent dry-out. Before starting the unit, check the seals' integrity and replace if required. If seal replacement is
required, purge and add grease to the newly installed seals prior to unit operation.
