When reporting the repair, use "PS5689" as the Part Number and "7755" as the Group Number. Use "96" as the Warranty Claim Description Code and use "Z" as the SIMS Description Code.
Although this Program is to be administered as described above on the Affected Product, parts should be removed from Parts Stock as soon as possible.
Termination Date
October 31, 2000Problem
The spindle needs to be replaced when cracks are present at the 8G4573 Final Drive on certain 527 Track Type Skidders. An improved 1786851 Spindle has some improvements in the heat treatment length and has also a larger diameter which makes it necessary to replace the current hub by 1786854 Hub.
This program is for customer owned machines. A separate before-or-after failure program is applicable for machines in dealers inventory only.
