Special Clutch Kit TYPE-R

Special clutch kit that allows you to use the stock main shaft (stock transmission) as is and install a high end clutch unit

■Special Clutch Cover TYPE-R (DRY) Detail
Die-cast aluminum R. Crankcase cover is adopted.
The surface is painted silver.
WET and DRY R. Crankcase cover shape is common, so it is possible to change both wet and dry specifications after purchase.
The clutch part has a separate chamber structure, and in the case of a wet clutch, the engine oil and the clutch oil can be separated.(Brand name, specification, etc.)

The clutch type is a wire type. The rack and pinion system, which is known for its light and smooth operation, is used.
The surface of the forged aluminum clutch cover has been shot blasted.
The cover for the dry clutch has a large ventilation hole to improve the cooling effect.

■Built-in oil element / oil through nut
■Built-in oil element
Filters out impurities such as sludge and metal wear particles in the oil.
The oil element is a cartridge type paper type.

■Oil through nut
Substantial weight reduction can be done!!!
Centrifugal oil filter approx.1069g → Oil through nut approx.123g
You can remove the stock centrifugal oil filter which puts a burden on the crankshaft by replacing it with the attached oil through nut.
This allows the crankshaft weight to be reduced from approximately 1069g to approximately 123g, resulting in a significant weight reduction.
Also, the engine response will be improved by reducing the load on the crankshaft.
By installing the oil through nut, the oil line leads to the crankshaft.
Because it passes through the oil element, clean oil always flows to the crankshaft.

■Oil level check window

■Large filler cap

■Optional parts (oil cooler / thermostat) can be installed.
■Oil outlet
Oil can be taken out from the cover body directly to the oil cooler.
SP Takekawa has the oil cooler kit for the vehicle with special clutch cover.

■Patented structure: Thermostat mounting and oil line structure
Overcooling can be prevented by installing optional thermostat unit when SP Takegawa's oil cooler kit (with the specification that oil is taken out from the clutch cover) is installed.
*Must be installed with SP Takegawa oil cooler kit.

■Optional parts (oil line hose) can be installed
■New mechanism
The oil line that flows to the cylinder head side can be changed to go through the oil element.
By installing the oil line hose kit (sold separately), oil flowing to the head side can also pass through the oil element.
This prevents engine damage caused by oil sludge.

To install the oil line hose, you need to use the oil outlet boss on the SP Takegawa big bore cylinder (with oil outlet boss).
It cannot be installed to the big bore cylinder without oil extraction boss on SP Takekawa's e stage.

■Special Clutch Inner Kit TYPE-R (For Stock Main Shaft)
By using the special adapter, installing the special clutch with the stock main shaft (stock transmission) can be done.This eliminates the need to disassemble the crankcase and allows the clutch to be assembled with the engine still mounted in the vehicle.

■6-disc specification
You can choose between a wet clutch and a dry clutch.
By reducing the diameter of the rotating parts such as the clutch outer, the loss of horsepower due to oil diffusion is reduced, the response is further improved, and the rotating mass weight is reduced, so the engine power can be transmitted without waste.
Six-disc design is realized by using five friction discs and one judder friction disc.This reduces judder when starting and at the same time increases the clutch capacity to accommodate high power engines.
In addition, the clutch unit can be used for both wet and dry clutches, making it possible to change the specifications for both.

When changing from a wet clutch to a dry clutch, it is necessary to replace the friction disc.When changing from a dry clutch to a wet clutch, the clutch can be used without modification.
Only if there is no replacement of consumable parts.In addition, clutch cover etc.are required separately.

The clutch structure of this product is without slipper clutch.

■Primary driven gear with built-in damper
Built-in rubber damper to reduce shock to gears when clutch is engaged.

■Clutch spring
Excellent fatigue resistance and stable clutch feel.

■About the target mission
Special Clutch Inner Kit TYPE-R (WET / DRY) (for stock main shaft) must be used with stock transmission.
This product can also be used for those who have SP Takegawa's TAF 5-speed cross transmission kit (02-04-0293) installed with the stock clutch.

Cannot be installed on vehicles equipped with SP Takekawa TAF 5 speed cross transmission kit (for special clutch / 02-04-0295).
