ASSEMBLY
1. Place reducer on blocks so that it lays flat with the input
shaft down
2. Position adapter on reducer output hub so that small end
(end with 12 holes) rests on reducer. Select the 4 mounting
holes to match the shaft used (see Fig. 1).
3. Place adapter screws and lockwashers through adapter and
thread into reducer. Do not tighten.
4. Select either lip type or braided type seals and install as
follows:
Lip Type Seals – Place seal in adapter so that spring faces
out. Seal should be tapped evenly into place in the adapter
with a soft hammer, applying force only on the outer corner
of the seal. Fill cavity between lips of seal with grease. Install
seal retainer ring by tapping with a hammer. Apply grease
to adapter section of shaft (middle section). Slide shaft,
keyseated end first, into adapter and through reducer.
Note: Be extremely careful when sliding adapter section
of shaft through seal to prevent seal lips from being
damaged or rolled over.
Braided Type Seals – Flatten both seals with a soft
hammer. Place seals in adapter, one on top of the other with
joints offset from each other. Lay retaining ring loosely on
top of seals. Slide shaft, keyseated end first, into adapter
and through reducer. Take care to clear the seals with the
adapter section of the shaft. Once shaft has bottomed, seat
retainer ring by simultaneously hitting the face of the ring on
opposite sides of the shaft with two hammers.
5. Carefully place reducer on its side. Rotate shaft to align
keyseats in shaft and output hub and install key. Install
shaft retainer, lockwasher and bolt. Tighten bolt to torque
specified in Table 4.
6. Lay reducer on blocks With input shaft down and tighten
adapter bolts to torque specified in Table 4.
7. If waste packing is to be used, it may be installed through
access hole provided in the adapter. Waste packing, not
furnished with the screw conveyor drive, may be used as a
separate seal option or in combination with either the lip or
braided seals.

shaft down.
2. Position adapter on reducer output hub so that small end
(end with 12 holes) rests on reducer. Select the 4 mounting
holes to match the shaft used. See Fig. 1.
3. Place adapter screws and lockwashers through adapter and
thread into reducer. Do not tighten.
4. Install 2 screws in studs in the adapter. Use Loctite on
threads. See Fig. 2.
Flatten braided seals with a soft hammer. Place seals in
adapter, one on top of the other with joints offset from each
other. Lay retaining ring loosely on top of seals. Slide shaft,
keyseated end first, into adapter and through adjusting
flange into reducer. Take care to clear the seals with the
adapter section of the shaft. Once shaft has bottomed, seat
retainer ring by tapping with a hammer. Install adjustable
flange and secure with hex nuts provided.
5. Carefully place reducer on its side. Rotate shaft to align
keyseats in shaft and output hub and install key. Install shaft
retainer, lockwasher, and bolt.
6. Tighten bolts per Table 4.
7. Lay reducer on blocks with input shaft down and tighten
adapter bolts per Table 4.

MOTOR INSTALLATION
Consult the local Char-Lynn Motor dealer for hydraulic motor
information.
INSTALLATION
1. Determine the running positions of the reducer. (See Fig.
3) Note that the reducer is supplied with 7 plugs; 5 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 3 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 top face of the reducer housing. Use
the hole in the bottom face for the magnetic drain plug. Of
the 5 remaining holes on the sides of the reducer, use a plug
in the upper housing half for the minimum oil level plug.
