I have a 2021 Schwinn High Timbre 27.5" mountain bike with a bent rear axle and grinding bearings. I need to overhaul the hub, but I cannot get the 7-speed freewheel off. I don't know who the manufacturer of the freewheel is. The only information stamped on the inner lock ring (with the two dimples) is LX (see photo 1).
I purchased the Park Tool freewheel remover tool FR 1.3 because it appeared to match the dimensions/configuration of the splines (see photo 2).
Park Tool FR 1.3 spec is 12 spline, 22.6 mm (measure 22.55 mm) suitable for Shimano style freewheels, but the actual dimension in the freewheel is 23 mm (measured 23.07 mm). When I apply force (significant) to undo the freewheel, the tool skips splines. Three questions:
- can anyone tell me the manufacturer, make and model of this freewheel?
- any advice on how to get the freewheel off since the park tool doesn't work?
- if all else fails, and I decide to disassemble (destroy) the freewheel, which way does the outer lock ring (with the four square shaped notches) turn to undo (CW or CCW)?
