PROBLEM
The existing 211-7328 Suspension Cylinder Bearing Seal may fail on certain 735B, 740B, and 740B EJ Articulated Trucks. If the existing seal fails it could result in premature suspension cylinder bearing failures. In some applications, the type of grease used to lubricate the bearings may contribute to premature failure. |
