Trailer Suspension System Components and General Maintenance Guidelines ConƟnued

PIVOT CONNECTION - A correct pivot connecƟon is crucial to the life of the suspension. The pivot fastener must conƟnually provide a sufficient clamp load through the bushing to prevent premature suspension fail- ure. Hendrick-son INTRAAX suspension systems come equipped with QUIK-ALIGN pivot connecƟon hard- ware. The hardware consists of a specially plated shear bolt to ensure a proper clamp load, (550 Ō-lbs, H-45 torque). TRI-FUNCTIONAL BUSHING - have unique properƟes that will provide years of maintenance-free service. The TRI-FUNCTIONAL BUSHING (located at the suspension pivot connecƟon) provides a resilient connecƟon that allows an axle to walk without excessive flexing. The TRI-FUNCTIONAL BUSHING, in conjuncƟon with the rigid axle connecƟon, results in a roll-stable suspension design that resists trailer lean independent of the air spring loading. Reference Hendrickson service guide L427 for bushing replacement procedures.

NOTICE Failure to properly torque the pivot bolts may result in loss of warran- ty coverage.
