Sleeve Transmission Shaft, 18.5mm Width, (O-ring for shaft see item 10196) OEM Reference # 90387-25507

Drive Sprocket Bushing for Conversion to 520/530 Sprocket Chain Kit

• The 530 sprocket is wider than the 520 sprocket, so when converting to the other chain pitch (and only then) a different spacer bushing is needed to be able to mount the sprocket nut and lock plate correctly
• Check the width of the existing bushing before fitting!
• The gearbox output O-ring should also be replaced - see item 10196
