If the 2 sections of your APS adjuster get stuck together in the fully open position it will prevent you from being able to preload the system and play may exist.
Remove the crankset from the bike following the directions for your crank model found in our How-to section and then try this:.
With the crank off the bike, install the APS adjuster onto the keyway of the crank where it would normally sit. Use a strap wrench (or protect the outer ring of the APS with an old tube/rag and use an adjustable pliers) to turn the outer ring of the APS in the direction of the tighten arrow shown on the outside of the APS so that the inner ring moves away from the outer ring and the assembly will loosen enough to be turned by hand.
If that does not work, reach out to us on our support contact page and we can assist further.
