Setup, Compatibility & Care
To install these hub caps, ensure the hub surface is clean and free of old grease residue. Press the cap firmly into the center of the hub housing; you may need to use a soft-faced rubber mallet to ensure the cap is fully seated and flush.
Compatibility Requirements:
- System: Ifor Williams trailers with bolt-on Knott brakes.
- Year: 1996 onwards.
- Measurement: Internal hub diameter must be exactly 76mm.
Care Instructions:
- Avoid using high-pressure power washers directly at the seal, as this can force water past the cap.
- During every tire change or bearing service, remove the cap to inspect for internal moisture or contaminated grease.
- If the cap shows signs of deformation or cracking, replace immediately to prevent bearing damage.
