Drum Sprocket; Chain Tightener - Schulte SMR-800 Operator's Manual

Drum Sprocket

After locking the collars on drum end bearings, slide
big sprocket on shaft until it is against lock collar.
Insert hub and keys into sprocket.
Tighten hub by alternately tightening the three bolts
in hub. Tighten the bolts to 29 ft.-lbs (39 Nm). Over
tightening will strip out bolts.

Chain Tightener

1. Align the top sprocket and install the chain.
2. Install the two idler arms and sprockets so the
sprockets line up with the chain. Spacers
should be used to ensure the tension brackets
clear the chain.
3. Install the tension bolt and torque one nut to no
more than 5 ft. lbs.
4. Install the second jam nut and lock it too the
first nut to prevent backing off.
Proper tension is achieved
approximately 1/4" of movement in the chain
between the drive sprocket and idler.
