INSTALLATION

1. 

Use lifting bracket to lift reducer.

2. 

Determine the running positions of the reducer. (See 

Figure 1). Note that the reducer is supplied with 6 

plugs; 4 around the sides for horizontal installations 

and 1 on each face for vertical installations. These 

plugs must be arranged relative to the running 

positions as follows:

Horizontal Installations

–Install the magnetic drain 

plug in the hole closest to the bottom of the reducer. 

Throw away the tape that covers the filter/ventilation plug 

in shipment and install plug in topmost hole. Of the 2 

remaining plugs on the sides of the reducer, the lowest 

one is the minimum oil level plug.

Vertical Installations

–Install the filter/ventilation plug in 

the hole provided in the upper face of the reducer housing 

as installed. If space is restricted on the upper face, install 

the vent in the highest hole on the side of the reducer per 

Figure 1. Install a plug in the hole in the bottom face of 

the reducer. Do not use this hole for the magnetic drain 

plug. Of the remaining holes on the sides of the reducer, 

use the plug in the upper housing half for the minimum oil 

level plug.
