2. Prior to reassembly, run grease through zerks to clean passages. Be sure all parts are clean and free from foreign matter before reassembling.
3. Install front frame to articulation link connecting point as follows:
a. Tap bearing spacer into lower ear of front frame.
b. Hold articulation link in place between ears of the front frame.
| NOTICE |
