Stronger Bearing Clamps For Rear Suspension A-Frames{7200,7050}
Usage:
D330B, D330C, D350B, D350C, D350D, D400 and D400D Trucks
Improved clamps are now used to retain the rear suspension A-frame bearings. The new 2U6397 Ring Clamps replace the former 4U2419 Ring clamps. The former clamps can distort and crack which allows excessive lateral movement of the bearing.
The new 2U6397 Ring Clamps are effective with D350D...9RF300, D400D...8TF305 and D400D...4EJ0019 Trucks and are adaptable to earlier trucks.
The location of the ring clamps is shown in the illustration. The illustration is typical and may not exactly represent your machine.
