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.
