Heavy-duty steel 1956348 rear wheel rim from the GX-AFTER range. Dedicated to Caterpillar (CAT) backhoe loaders series E and F. This 28-inch rim is designed to fit industrial tires size 16.9-28 (or metric 440/80-28). The structure features 10 mounting holes and a precise center bore of 283.5 mm, characteristic for CAT drive axles.
GX-AFTER rims are manufactured from rolled steel with increased fatigue strength. Precise disc stamping and robotic welding guarantee perfect geometry (no runout) and safety under heavy loads.
| Machine Type | Models / Series |
|---|---|
| Backhoe Loaders | 422E, 424, 424B, 424B HD, 424B2, 426 F2, 428E, 434E (check tire size) |
The model list is for reference. It is crucial to check the tire size (16.9-28) and center bore diameter (283.5 mm) on your machine.
The rim is sold without a tire and fasteners. New wheel nuts and hub studs may be needed for installation. We also recommend installing a new valve stem.
Driving on a cracked or bent rim risks sudden tire pressure loss and, in extreme cases, wheel detachment from the hub. Fatigue cracks near mounting holes are a sign for immediate rim replacement.
The rim transmits torque from the hub to the tire and supports the weight of the machine.
