1.     Standard Drafting Standard technical drawing is a uniformity that has been agreed in order to avoid misunderstandings in communication techniques. People involved in the field of engineering drawings need to know about the standards. Related persons include students in technology and industry groups, the product planners, machine operators, assembly operators, mechanics and control the quality of a product / machine.  Standard drawing techniques can be applied within the company, between companies / industries within a country, even the standard can be applied to engineering drawings of industrial inter-state known as International Standards or abbreviated SI. Countries that have made a standard is: a.     Japanese Industrial Standard (JIS)      for more info: JISC b.     Nederland Normalisatie Instituut (NNI)      for more info: NNI c.     Deutsche Industrie Normen (DI...

A. Colar lubrication on the primary pulley Reason: If there are no lubrication, acceleration / acceleration is not smooth because of the movement on the primary sheave adapter does not work well Service Point First, lubricate the grease on the surface of the collar, then before the primary pulley mounted on a fixed, clean the excess fat on the outside of the oil seal to prevent slippage B. The inside of the starter wheel gear, starter idle gear, the drive axle of the secondary sheave Reason: Rotation is not smooth (1) point lubrication • Pulley primary shift • Collar Grease suggested: Shell Sunlight 3 ® Shell Sunlight 3: is grease versatile and is suitable for lubricating roller and plain bearing Resistance Temperature: 20 * C to 135 * C Caution: Do not touch the surface of the pulley with grease.              If pulley exposed to grease, clean with ALCOHOL C. Lubrication Torque...

Many people use motorcycle scooter for daily activities. There for, you must know how the new scooter work! they use CVT system. Continue Variable Transmission or CVT is the transfer rate system for full automatic speed according to engine speed. This system does not use gear transmission, but the V-belt it self. CVT works fully automatic transmission, that  affected by the load and engine speed. During Idle Rotation The engine speed is not connected to the rear wheel stalled due to the rotation of the centrifugal clutch and the clutch does not touch on the clutch housing. you can read the system using this picture below . energy from engine passed to the rod that moving the front pulley. the front pulley is closing (narrow), but the rear pulley is open wide. this action give v-belt to rotate the pulley, but the wheel is still stop. During Intermediate Rotation After the idle rotation, we can accelerate the scooter. rotation...
