Identify the right cap
Some models used a different cap for manual and power steering, and later caps often replace earlier styles through a chain of superseded part numbers. Note the steering type, the tractor model and serial number, and any number moulded on the underside of the old cap.
Check how the cap is held on: snap-in lugs, a spring clip, screws, or a press fit into the hub. A replacement only works if the retention matches.
Logos and emblems
Many original caps carry a manufacturer emblem. PorkForge never reproduces manufacturer logos or emblems; a reproduced cap is plain or carries neutral text only. If the emblem matters to your restoration, keep and refit an original insert where the design allows.
Materials
Caps sit in direct sunlight, so the material must resist UV and summer heat. Material and colour are confirmed for each design before a part is offered, and caps on safety-related steering components are not reproduced.
Removing the old cap
Most caps pull or lever straight out. If a previous owner glued one in, work slowly around the edge with a plastic trim tool rather than a screwdriver, so the wheel is not marked. Keep the old cap even if it is broken: the pieces show the retention and the exact size of the hub opening.
What to measure before you request one
- Outer diameter at the widest point
- Overall height from the wheel face to the top of the cap
- Diameter and depth of the section that fits into the wheel hub
- Number, width and spacing of clips, lugs or screw holes
- Photos from the top, the side and underneath, with a ruler in shot
