Installation 1. Place the oil seals for the cover on the sprocket halves.
3. Measure the distance
“C” between the sprocket faces and firmly fasten the set bolt (refer to Specifications table, pg.4). 4. Lubricate the chain with grease, then wrap the chain around both sprockets and fix with the connecting pin. 5. Fill the required quantity of grease into both sides of case and fasten them firmly. Do not forget to use gaskets. Notes: 1. During high-speed operations or conditions of large vibration, please use locking cement when fastening the bolts. 2. Install a cover when there is a risk of chain breakage. 3. Ambient temperature range is 14˚ to 140˚F. If
2. Bring the sprocket faces close together and correct the angular and offset misalignment.
Place a straight edge at the bottom of corresponding teeth of the two sprockets and adjust so that the offset misalignment is minimized. The allowable offset misalignment is 2% of the chain pitch.
Adjust the angular misalignment (alpha

symbol) so that the width of the tooth surface T is the same around the circumference of the sprockets. The allowable angular misalignment is 1˚.
When the sprocket speed is 1/3 or more of the maximum speed (i.e., it lies on the right side of the dark line in the Horsepower Rating table, pg.3), the allowable angular and offset misalignments are 0.5˚ and 1% of the chain pitch.
