PROBLEM

Show/hide table

Certain 966K and 972K have received the incorrect 364-8483 Bearing from the factory and will need to be replaced with the correct 9M-1328 Bearing, on the rod end assembly in the 319-5045 Cylinder Group. The bearings will need replaced on the left and right side. The 364-8483 Bearing lacks a grease passage through the inner race to the pin that could lead to early hour wear on the pin.
