PROBLEM
The front suspension A-Frame bearing may not be receiving an adequate amount of grease on machines that are equipped with the factory fitted Automatic Lubrication System. An inadequate amount of grease supply to the bearing does not promote purging of grease through the joint, especially in severe applications. This may result in premature wear of the bearing.
A larger sized injector is available which increases the amount of grease that is supplied to the bearing
Note: This service letter covers machines with factory fitted Automatic Lubrication Systems only. Dealer installed Automatic Lubrications Systems are not covered.
