(1) Apply 9S3263 Thread Lock to the bolt threads.(2), (4) Total end play (A) between eccentric shaft (2) and bearing (4) ... 0.76 to 2.45 mm (.030 to .096 in)(3) Use 4C5300 Gasket Maker as required.(5) Apply 6V4876 Molykote. (6) Tighten nuts to a torque of ... 640 N m (470 lb ft)(7) Apply 9S3263 Thread Lock to the bolt threads.(8) Apply 9S3263 Thread Lock to the threads of the nut and torque to ... 200 15 N m (148 11 lb ft)(9) Use 6V4876 Molykote Lubricant on vibration motor splines as required.(10) Tighten bolts to a torque of ... 88 10 N m (65 7 lb ft) Dimension B, clearance from motor mounting surface to coupling spacer, should be 46.88 to 50.5 mm (1.846 to 1.99 in)Dimension B (minimum) = 46.12 mm (1.816 in) + dimension A (eccentric shaft end play). Dimension B (maximum) = 50.5 mm (1.99 in).Measure dimension B with eccentric shaft and coupling pushed in as far as possible. Vibration Frequency Sensor Adjustment (Option)
Typical Example Sensor adjustment must be made with the motor installed.1. Loosen the locknut and turn vibration frequency sensor (1) until contact is made with sprocket (2), and back out one turn. Dimension (A), the clearance between the sprocket and vibration frequency sensor, must be 1.5 mm (.06 in). Then tighten the locknut.
