Hubcap Installation on Hendrickson Axles


There are certain hub caps that interfere with the Hendrickson P Series Precision 320 spindle nut. This is an issue with the hub cap and spindle nut, and not the P.S.I. ATIS.



Please visit and refer to PIL-18B001 - MTIS Hubcap interference with Hendrickson 320 Spindle Nut.pdf for a list of P.S.I. ATIS ready hub caps that have been validated to provide sufficient clearance on the Hendrickson axles equipped with this nut.
