It is possible to cut out the top of the cam cover of NA6 and NA8.
As soon as the engine starts the cam gears turn making a terrific noise quite unfavorable to a mechanic.
In addition, in case the stock cam gears are uninstalled and taken out, it is possible to modify the valve timing easily in the process of installation of variable cam gears.
Touching the cam gears simply directs to the meaning that it can be easily maintained.
However, it is not advisable to show cam gears without any protection..
With the help of the timing belt, the revolution of the crankshaft is transferred to the camshaft.
Therefore, not only the internal parts of the engine, any kind of hindrance to the timing belt or the cam gear might cause big trouble.
Hence the manufacturers always make sure that the timing belt is perfectly covered completely.
Maruha timing belt cover is manufactured very uniquely.
The timing belt cover is easily fixed after cutting out the top portion of the cam cover giving it a very sleek and cool look.
The bolt hole of the stock cover is used in the process of fixing of the cover, making it less time consuming and can be easily installed.
The manufacturing material is specifically Real Carbon. (Note: It is not dry carbon.)
(As shown in the picture, the red circled parts are the genuine bolt hole utilized to make the installation simple and easy).
Not only does it appear cool but it also plays a very important role by helping in the rotation of the timing belt and the cam gears.
Simultaneously, it certain clearance and secure the internal rotating parts.
Disregarding the cost we have compiled external and internal part and added tall feature to the cover.
As you can see in the picture above, the internal design is refined clearly to guarantee clearance between internal rotations.
Furthermore pay attention to the installation of the bolt.
The carbon cover is fixed by the bolt but the stress of the bolt is caught by the cover, preventing damage.
The fact of dropping fragment in the timing belt cannot be avoided. Therefore, we have designed it exclusively by using aluminum collars.
Since it is just fit, the collars confronts to the vis-a-vis contact surface of the back plate, preventing the bolt stress from transferring to the cover.
On the other hand, the use of the rubber O-ring along with the bolt fixes it certainly and stops vibration.
As shown in the picture below, the red painted surface and the non painted surface are originally one identical part .
the bulged out side and the covering side shares the same wall.
They are both cut divided into two parts leaving a thickness of 0.1mm from the original thickness of 2 mm.
This means that the bulged out part is cut out.
(As in the picture white circular section which is originally the same wall, is cut divided)
This kind of cut processing is called as wire cutting.
We use the exclusive cam cover jig of the Roadster(Miata) in Maruha.
After setting it in the tank with full water, cutting process is carried out by passing electric current through a very thin wire.
This cuts the cover top accurately and also gives a neat finish. This enables us to install the timing cover easily later.
Rephrasing the sentence, in order to install the timing cover it is necessary to cut out the cam cover acuurately.
After cutting, the rugged surface is polished with the file and paper and then painted.
After cutting out the cover, the soiling and oil is removed from the surface with a steam washer.
It is then sand blasted and rewashed with steam. The foundation to paint is applied followed by several application of raw paint.
The blast processes the foundation to paint securely and betters close adhesion of the paint.
In the intermediate process holograph can be used. Finishing is done by glossing .Glossing makes the surface hard and resistant to heat.
An exclusive finished cam cover suited for the engine compartment is accomplished.
The surface paint can be damaged easily by the friction of the volts and the cam cover surface.
Exclusive cam cover washer is used in order to prevent damage by friction.
