Astra Honda Motor announced to Honda PCX160 and ADV160 owners to check parts at the nearest authorized dealer. This is due to a Product Update related to the replacement of Face Set Drive. This program is not fully addressed to all users of the two scooters, but only those who receive a summons.
The letter that was distributed to consumers said it was face set driven, but on the body of the text it was written Pulley Assy, Driven. That means there are some components that need to be replaced. Our assumption of replacement includes the face set driven, double clutch and clutch bowl or a set of Secondary Sheave (Driven Pulley). So how does the rear CVT component work?
In the CVT transmission there are 3 main components that play an important role in transmitting power to the wheels of the vehicle.
- Primary Sheave (Drive Pulley)
- Secondary Sheave (Driven Pulley)
- V-belt
The Primary Sheave is located at the front, while the Secondary Sheave is at the back. These two components are connected by a V-belt. These three components determine the amount of output in the form of torque and speed, which are then channeled to the axle and then to the wheels of the vehicle.
The operation of this transmission is by shifting the diameter of the V-belt on both parts of the pulley. When "low gear" or just running, the radius of the drive pulley is small, while the driven pulley is large. Meanwhile, when the "high gear" is the opposite, the radius of the drive pulley increases, the driven pulley decreases.
Regarding Secondary Sheave (Driven Pulley) or secondary Pulley consisting of Secondary Fixed Sheave (fixed secondary pulley), Secondary Sliding Sheave (moving secondary pulley), Secondary Sheave Spring, Secondary Shaft (secondary pole), clutch carrier (centrifugal clutch), clutch housing (clutch housing), cam torque and reduction gear.
Problems that often arise are usually from the clutch housing (bowl), centrifugal clutch lining and secondary sliding sheave.
Symptoms of the clutch housing (clutch housing) is usually a halting acceleration at lower revs. The indication is because the shape of the bowl is no longer flat. So that it is not optimal to bind the clutch lining. This condition could be due to frequent opening of the gas and braking immediately.
Then from the centrifugal clutch lining which starts to wear out. Usually there is a squeaking sound, the acceleration of the motor feels slower both at the lower and upper rounds. Then the secondary sliding sheave which is worn or eroded due to the continuous rotation of the V-Belt. In addition to the rough sound, the symptom caused is that acceleration at mid-speed feels stuck, but returns to normal as the engine speed increases. The habit of hitting the gas cycle can be the cause of this problem.
As we know, in the summons, the reason for Honda to withdraw the PCX160 and ADV160 is due to the potential decrease in face set driven performance and noise (noisy) in the CVT area. The reason is that there is an error in the production process. As stated in the following announcement:
"Uneven part thickness due to an imperfect production process, which in the long run can potentially cause noise in the CVT area and result in a decrease in the performance of the part. To avoid this, customer calls and CVT component replacement (Pulley Assy., Driven) are carried out at official Honda motorcycle repair shop free of charge. Immediately contact the nearest AHASS or call our contact center 1-500-989 to get product updates for free."
