New Bearing Improves Differential Shafts Reliability {4066}
Usage:
PS300B (4PN) Pneumatic Roller Vibratory Compactors
Description of Change: The new bearing is now made of a harder material and a new radius has been introduced.
Adaptable To: The new 183-5196 Bearing (1) is going to replace the 145-4583 Bearing. This bearing is effective for the PS300B (4PN288) and can be retrofitted to the earlier PS300B (4PN1-287).
NOTE: Any time a differential shaft failure occurs, both of the existing bearings must be replaced by the new 183-5196 Bearing.
