OTC, an SPX Brand, has released its Hendrickson-approved Quick Alignment Socket, no. 1767, and Quick Wrench, no. 1768, designed to improve productivity when servicing PRIMAAX suspensions. The OTC 1767 Quick Alignment Socket can be used to adjust axle alignment on the PRIMAAX air suspension and works on PRIMAAX models 230, 460, and 690 suspensions. The OTC 1768 Quick Wrench is used to torque cross-tube end-cap bolts and longitudinal torque rod top-pad bolts. It reduces maintenance time by eliminating the need to remove the tires to access the end-cap bolt. The Quick Wrench can be used with the following Hendrickson PRIMAAX suspensions:
- Type A: PAX 230/460/690 and FMX 240/480 with 8-1/2" ride height.
- Type B: PAX 230/460/690 with 10" ride height.
