Power Clutch Impression and Supplements

With the start of sale of MARUHA POWER CLUTCH SYSTEM, we have already received many inquiries regarding the new power clutch and in this section we will provide brief explanation about the power clutch impression and its supplements. Itfs a very common impression that the word clutch is associated with something heavy. Therefore people prefer carbon instead of metal clutch. However it would be wrong to be judgmental. MARUHA POWER CLUTCH SYSTEM (metal) is designed to reduce the pedal effort and is light. The factors of concern are the following:

1. Pedal effort

Generally a heavy pedal clutch requires heavy effort.
It is quite disturbing in traffic jams and red light signals, while driving with the heavy duty clutch pedal.
In MARUHA POWER CLUTCH the spring lever ratio is set accordingly that it lightens the pedal effort and covers a pressure up to 1,000Kgf.

Shown in the above photograph is a pedal effort tester.

The tester is hooked to the pedal and the substantial power is grasped by the meter (in Kg).

Case1:STANDARD CLUTCH18Kg.
Case2:STANDARD FORM STRENGTENING CLUTCH20Kg.
Case3:SYSTEM CLUTCHES (competitors)30Kg.
Case 4:MARUHA POWER CLUTCH19kg.

MARUHA POWER CLUTCH has been tested with the Maruha test car and hence we can prove our statement.
However the data of the power clutch differs with the elapse of time (approximately 1 year).
The point is the sliding of the release bearing.
Although it is trivial thing, Refilling of release bearing grease is a very important job. It gives a lighter pedal feel.
The strengthening clutch of standard product is bonding power 600Kgf, and the weight is reflected in the pedal respectively.
Most of us think that a foot pressure of 20 kg is easy to handle and a plus minus of 1 or 2 kg does not make any difference.
However you can practically feel the difference.
The imitation clutch system of 30kg requires rather heavy pedal effort.
A little power release results in the pedal repulsion.
While in the circuit this kind of repulsion is sufficient but for normal drive a difference of 10 kg makes a huge difference.

2. Half- clutch

The eeasinessf as well as the edifficultyf of the half clutch are firstly related to the pedal effort because the light pedal is delicate and simple to operate.
Second factor is the disk material. In other words, some materials are easy to slide on and some are difficult.
Maruha has two types of power clutch, metal and carbon.

Carbon disk:


Easy to slide in low temperature and provides good subordination as the temperature rises.

Metal disk:


There is a misconception that metal disk is not a good option .
However metal disk has been in demand for quite sometime now.
You can ride normally using the metal disk as well.
Firstly, Maruha has adopted the following methods to improve result.
Lubricity is included in the material of the metal, width of the semi- clutch is expanded, and operativity has improved rapidly.
Maruha metal disk provides a wear power of 1000kgf which is perfectly suited for Roadster.
It is possible to make the clutch & the disk lock securely making use of this wear power.
Secondly, standard disk feather for street rides is 3 but in Maruha the number of feathers is increased, the semi- clutch becoming too severe.
Since it is to lock 6 feathers with 1000kgf, bonding stabilizes and lock ratio increases rapidly.
It results in, considerably decreased output and also adds to the light weight factor.
Thirdly, the standard disk diameter for genuine parts ranges from 200 to 210 mm. There are other competitors as well who provide 225mm. However Maruha disk diameter is 230mm, the largest.
Enlargement of disk diameter to the maximum is very effective.

3. Pickup and shift change

Increasing of disk diameter means addition of weight.
But Maruha disk, both carbon and metal is considerably lightweight.
As for the carbon, it is only 500gm and metal has succeeded in achieving the target of mere 800gms.
The total weight of the set of lightweight flywheel, lightweight disk and the forging aluminum cover is approximately 8kg.
This factor provides sharp pickup and well shift change .

4. The Sound

In the former clutch systems, there was a typical sound when the clutch was pressed.
Reason being the pressure cover and the connection by the ring spring but with the new system angular clutch connection sound is subsidized.

Concluding Maruha Power clutch system (metal) is easy to handle and provides:

It is the up-to-date clutch system which we would recommend you to use by all means.
