  • Patent number: 11892037
    Abstract: An improved clutch basket assembly is disclosed. The improved clutch basket assembly provides improved wear resistance at the interfaces between friction discs and a clutch basket housing while allowing an operator to have improved clutch lever control and modulation when manually engaging or disengaging the clutch system. The improved clutch basket assembly includes a generally cylindrical clutch basket having a sidewall, a closed first end and an open second end. A plurality of removable pins is attached to the sidewall. A plurality of frictions disks is mounted in said clutch basket. The friction disks each have a plurality of positioning tabs extending out from a periphery of each of the friction disks. The positioning tabs are configured for engagement with at least one adjacent removable pin removably attached to the sidewall.

  • Patent number: 11673623
    Abstract: An improved master cylinder for use with a hydraulic clutch or hydraulic brake system. The master cylinder has a master cylinder body defining a bore. A piston is configured to slide in the bore when an actuation lever is compressed by a user. Sliding of the piston as a result of the depression of the lever causes the piston to depress a spring and to increase hydraulic pressure in the hydraulic line leading to the brake or clutch. A spring is configured to return the piston when pressure is released from the actuation lever. The master cylinder body in some embodiments is configured for lateral position adjustment relative to a mounting bracket. In some embodiments the master cylinder has a reservoir. The reservoir can be oriented at a tilted angle relative to the body of the master cylinder. In further embodiments the master cylinder has an outlet nut that is configured for attachment to the hydraulic line.

  • Patent number: 10180165
    Abstract: An improved liner and friction disk for a clutch basket is disclosed. The improved liner is easily retrofitted into a typical clutch basket and is held in place without fasteners or adhesives or special changes to the clutch basket. The improved liner is held in place without consideration to the outer diameter of the basket allowing the liner to work with a wider range of clutch basket designs and sizes. The liner provides an improved wear surface for the clutch basket's engagement surface with the driving friction surface. A friction disk with tabs adapted to fit inside the narrowed space provided by the improved liner is also disclosed.

  • Patent number: 9995347
    Abstract: An improved clutch pack is disclosed. The clutch pack incorporates liners, improved driving friction disks and driven disks where the thickness of the improved driving friction disks and driven disks are selected in order to allow more driving friction disks and more driven disks to be used within the improved clutch pack while maintaining approximately the same overall height as compared to the standard clutch pack the vehicles clutch system was designed for.

  • Patent number: 9157489
    Abstract: An adjuster is disclosed, to be placed “in-line” to a clutch disengagement system. The adjuster provides a means for lifting the pressure plate above the clutch pack without significantly affecting the operation or feel of the clutch disengagement system to the operator. Such an adjuster is particularly well suited for use with an automatic centrifugal clutch incorporating a friction disk that expands when rotated above a threshold speed.
