Toyota 13408-20010 PULLEY, Crankshaft

Detach the cable from the negative terminal of the battery. Remove the drive belt. Unbolt the bracket from the engine movement control rod. With the parking brake applied and the shifter in Park (automatic) or in gear (manual), loosen the lug nuts from the right front wheel, then raise the front of the vehicle and support it securely on jackstands. Remove the right front wheel and the right splash shield from the wheel well. Remove the bolt from the front of the crankshaft. A breaker bar will probably be necessary since the bolt is very tight. Using a puller that bolts to the crankshaft hub, remove the crankshaft pulley from the crankshaft. Note: Depending on the type of puller you have, it may be necessary to support the engine from above; remove the right side engine mount and lower the engine to gain sufficient clearance to use the puller. To install the crankshaft pulley, slide the pulley onto the crankshaft as far as it will slide on, then use a vibration damper installation tool to press the pulley onto the crankshaft. Note that the slot (keyway) in the hub must be aligned with the Woodruff key in the end of the crankshaft and that the crankshaft bolt can also be used to press the crankshaft pulley into position. Tighten the crankshaft bolt. The remaining installation steps are the reverse of removal.

The harmonic balancer assembly consists of two shafts contained in an upper and lower aluminum housing assembly. The shafts are geared together, and one of the shafts is geared to the crankshaft. The following procedure applies only when the harmonic balancer assembly is removed from the engine. Do NOT disassemble the harmonic balancer assembly! Start with the punch marks on the number 2 shaft lined up as indicated. The balancer shafts have punch marks and the number 2 housing has alignment notches - start with the shafts aligned, then align the number 2 shaft so that mark D is aligned with the housing. Using locking pliers to hold the number 2 shaft from turning, measure the backlash on the number 1 gear with a dial indicator. Set up the dial Indicator as shown and measure the backlash while applying mild hand pressure on the rear of both shafts, while keeping forward pressure on the rear of both shafts to eliminate thrust play. Compare the backlash to the specifications. Remove the dial indicator and turn the number 2 shaft so that punch mark E now aligns with the case. Measure backlash again compare the results with the specifications. Remove the dial indicator again and turn the number 2 shaft so that punch mark F now aligns with the case. Measure backlash again compare the results with the specifications. If any of the three measurements exceed the specifications, it is suggested that the harmonic balancer assembly be taken to a Toyota dealer or other qualified service facility for further disassembly and repair.

The remainder of the installation is the reverse of removal.
