wire type
The manual wire clutch operation mechanism is of the rack and pinion type, which enables stable clutch work.

Patented structure of clutch cover (thermostat mounting area and oil line structure).
This manual clutch cover has a patented structure that enables the installation of a thermostat, which is only available from SP Takegawa.The original oil line structure prevents overcooling by installing SP Takegawa thermostat (sold separately).

How to operate the thermostat
When the oil temperature rises (above 70°C), the shape memory alloy spring in the thermostat extends, blocks the bypass passage in the clutch cover, and changes the oil flow to via the oil cooler.
When the temperature is below 70 degrees, the spring contracts and only a small amount of oil flows to the oil cooler through the bypass passage.

Patent Application Structure of Clutch Cover
This manual clutch cover also features a patent-pending clutch cover construction that can be used with either manual wire or hydraulic clutches.Therefore, by purchasing the hydraulic clutch conversion kit after purchasing the manual wire type clutch cover, you can change to the hydraulic type without replacing the cover.

Standard oil outlet
The clutch cover is equipped with an oil outlet as a standard feature, so that the oil can be taken out to the oil cooler.

Special Clutch Kit
By changing to a 6 disc clutch compared to the standard clutch (5 discs), the clutch capacity will be increased and the set load of the spring can be set lower (in combination with the standard spring) to make the clutch operation lighter.

It can be used for both stock and custom engines.
The number and combination of clutch springs can be adjusted.
