S&S Coupler Maintenance
Removing the Two Retaining Rings and the Coupling Nut
You must remove both retaining rings and the coupling nut to thoroughly clean and inspect a coupling. ALWAYS TAKE CARE TO PROTECT THE COUPLING TEETH!
1. Slide the coupling nut back to expose the FIRST retaining ring.
Installing the coupling nut and the 2 retaining rings
Only install coupling nuts and BOTH retaining rings after the parts are thoroughly clean.
ALWAYS TAKE CARE TO PROTECT THE COUPLING TEETH!
1. Slide the clean replacement nut all the way onto the coupling lug with the threads out so the retaining ring groove is visible just beyond the edge of the coupling nut.
Re-seating can be done by sliding the ring back and forth using the nut and a screw driver.
* Removal, inspection, cleaning of debris from the ring and groove, and/or replacement of a bent or sprung ring may be necessary.
