Paint Options
Mounting RegistersMounting Registers on the 2000 Series products
enable a simpler installation for Base Mounted units. Use the
following steps to assist in the alignment between the reducer
output shaft and the shaft being driven (driven shaft).
1. Establish a reference edge that is parallel to the driven
shaft using dimension M as the offset.
2. Bank Reference Face 3 of the reducer against your reference
edge.
3. Use Reference Face 2 of the reducer for any fine angular
(yaw) or lateral adjustments.
Contacting thumbscrews against Reference Face 2 is a clever
method.
Tapered AdaptorsThe Tapered Adaptor is a valuable option that
ensures a simple and secure installation for Shaft Mounted
units.Use the following steps to assist in the alignment between
the reducer output shaft and the shaft being driven (driven shaft).
See page 17 for additional reference.
1. Make a score mark on your Driven Shaft at a length equal to
the Table 1 dimension from the mounting end.
2. Slide Support Bushing onto driven shaft, flange first, until
the flange reaches the score mark & secure with clamp
screw.
3. Mount Reducer onto Driven Shaft allowing it to slide through
the Tapered Bushing on the opposite end.
Expect the Tapered Bushing to be pushed outward from the reducer
as it expands inside the outer bore.
4. Align the holes between the Tapered Bushing and the Anchor
Plate.
5. Using a mallet, tap the Tapered Bushing inward until the
bolts are able to engage the Anchor Plate threads.
6. Tighten bolts evenly in sequence indicated in Bolt Tightening
Sequence Table on page 17.
7. Readjust Support Bushing as needed to ensure full engagement
of taper and re-secure clamp screw.

2000 Series Gear Motor and Gear Drive Installation
LubricationKlubersynth GH6-460 that is recommended for the 2000
Series gear drives for optimum performance. Normal full-load
operating temperatures range between 130F - 150F. During initial
break-in of the gear drive, higher than normal operating
temperatures may result. All gear drives are supplied with GH6-460
synthetic oil (unless specified otherwise) with quantity listed
below for standard mounting position 1 or to mounting specified at
time of order. These gear drives
are designed with internal features to reduce the impact of
metallic wear debris, which should increase maintenance intervals.
Relubrication is recommended for 15,000 hours or more frequently
when operating in highly contaminated environments. Satisfactory
performance may be obtained in some applications with non-synthetic
oils, but will require more frequent oil changes.
