Improved Lower Pin Joint for Bucket {6107, 6108, 6109, 6118}
- Wheel Loader:
- 988G (S/N: BNH1-UP; 2TW1-UP)
- 988H (S/N: BXY1-UP)
Description of Change: New shims are now used in the lower pin joints for the bucket on the above listed machines. These shims reduce the amount of axial play in the pin joint. This will increase the life of the seals and the lubricant. This will reduce wear on the bearing and the pin.
Adaptable To: The new shims are effective with the following machines:
- 988H (S/N: BXY2543-UP)
- 988G (S/N: BNH1-UP; 2TW1-UP)
- 988H (S/N: BXY1-2542)
