Nexen 5H70P 917500 - Manual (Page 6)

6 FORM NO. L-20008-V-0511
5H Tooth Clutches have a drive flange with a single bearing
and tapped mounting holes. 5HP Tooth Clutches have a
drive flange with two bearings, a pilot diameter, and tapped
holes for mounting a pulley, sprocket, gear, or coupling
adaptor (See Table 2 for recommended tightening torques
of Grade 8 socket head cap screws).
NOTE: Nexen recommends using a red anaerobic thread
locking compound on pilot mounting bolts.
Your Nexen Distributor carries Flexible Couplings
specifically designed for Nexen Tooth Clutches.
An optional Hub Collar is available if set screws are
required on the end opposite the Drive Flange or Pilot
Mount for 5HP models. This optional Hub Collar requires
drilling and tapping of holes in the end of the clutch (See
Table 3 for tapped hole dimensions and use the collar as a
hole location template).
NOTE: Both 5H and 5HP Tooth Clutches mount on a full
shaft using a customer supplied full length key.
1. Install the Flexible Coupling or bearing supported pulley,
sprocket, or gear (See Figure 1 and Table 1).
2. Insert the customer supplied key into the shaft (See
Figure 1).
3. Slide the Tooth Clutch onto the shaft and customer
supplied key (See Figure 1).
NOTE: Whenever possible, arrange the input drive to
the Tooth Clutch through the Drive Flange to prevent
clutch Ball Bearings from rotating unnecessarily.
4. Using the Set Screws (Item 16), secure the Tooth
Clutch to the Shaft (See Figure 1).
INSTALLATION
CAUTION
Do not connect the Clutch in-line without using
the Nexen Flexible Coupling. The internal
construction of the 5H Tooth Clutches will not
allow misalignment tolerances. (Refer to Sales
Literature L-20208).
