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 operating temperatures range between 150F - 170F. 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 20,000 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.
