In the case of this model ・The clutch does not disengage properly. ・It is difficult to set neutral. ・Shifting is hard even when the clutch lever is fully engaged. ・It is difficult to control the half-clutch. ・I can't make a quick connection. ・It stalls immediately. ・The touch changes greatly depending on the riding time and situation.(Heat Dare) It is effective for such things as.
Even if the "thickness of the friction disc" is within the manual's specified value when replacing the plate, if the cork grains are so black and carbonized that they cannot be distinguished, it means the plate has reached the end of its life. When you claw at it, it crunches, and it is charcoal instead of cork (friction material).
If you have replaced the clutch disc on this engine, you may have noticed that there is really only a little oil left in the disc. It burns very easily. You will understand the meaning of the groove cut shape that holds the oil.
This processed product does not depend on the frictional force and connection due to the surface roughness (initial roughness) of the original plate when it is new. The frictional force is obtained by increasing the flatness and contact area by chamfering, and by increasing the surface pressure by grooving. This type holds oil in the groove and reduces heat generation. 244ec42d7d6d26b413ec55f6a1aba8af2 ja 』『日々の暮らしのパートナー』 en A Partner for Everyday Life" It is flat and smooth because it is beveled. The touch changes less in the short and long term because of the small change in the decrease in the number of the touch. It retains oil and prevents carbonization of the friction disc. Normally, the friction disc and the clutch plate must be replaced at the same time or the clutch plate will start slipping soon, but with this processed plate, 2 sets of friction discs can be used. Although it is named "grooving chamfering plate", it is used for "chamfering by beating or bending to remove distortion when new", grooving, and final deburring chamfering. Is correct. Hand processed in our workshop.
■Supplemental image ・Customer's Serow 250, plate used for 1 year after grooving.Discolored, but good with little distortion and wear.The friction disc can also be used continuously, as the cork grains can be distinguished. ・This is a picture of the stock clutch plate (3XJ-) after a hard test.Only the speckled areas like this are hit.Only the area where it is hit is worn and flattened.When the friction material has been running for a long time (like a year), the friction discs are worn out and carbonized in the same way. ・The grooving and chamfering was one of the elements of "clutch tuning", which is the machining of the clutch itself.Since we receive many requests for processing only plates, we have also created a pre-processed product.
Caution
*The groove cutting process is different from that of YZ125 (X), etc., which have the same OEM part number used, so it cannot be used. *There may be changes in product specifications due to the manufacturer's reasons.
