Timing Pulley

Timing pulley is a part that transmits the rotational power
received from the timing belt to the shaft. Our products provide
sufficient tightening force without additional processing on shafts / pulleys, etc.
and support a variety of shaft fastening methods that are easy to install.

HOW TO INSTALL (SPA□, SPB)
  • 1. Wipe inner surface of shaft and hub to remove dust and oil.
  • 2. Wipe inner and outer surface of A.P.Lock or Taper Bushing.
  • 3. Spread anti-wear hydraulic oil or grease on to all inner surfaces.
    • 3.1 A.P. Lock which is made of aluminum alloy does not require any anti-wear hydraulic oil.
    • 3.2 Any oil type which includes molybdenumsulfur compounds or silicone is prohibited.
  • 4. Interlock A.P.Lock/Taper bushing with Timing Pulley and shaft respectively.
    • (Do not fasten screws when the shaft is not inserted due to deformation.)
  • 5. After positioning, fasten the screws as stated following.
    • 5.1 Fasten the screws with identical torque (1/8 of fastening torque) using torque wrench.
    • 5.2 Make sure you fasten the screws in sequential order as shown on the right figure.
    • 5.3 Repeat fastening the screws with 1/4 of fastening torque. (in diagonal order)
    • 5.4 Repeat fastening the screws with 1/2 of fastening torque. (in diagonal order)
    • 5.5 Finally fasten the screws with full fastening torque.
    • 5.6 Repeat fastening until screws don’t rotate any longer.
HOW TO DISASSEMBLE (SPA□, SPB)
  • 1. Remove external load (torque/thrust) on the shaft and Timing Pulley.
  • 2. Remove self-load of belt etc.
  • 3. Unfasten all screws in the same order when they were fastened.
  • 4. In case A.P. Lock or Taper bushing is not detached properly, try to disassemble using the tapped-hole for disassembly.
