NOTE: This bolt is one of the tightest on the entire car. The pulley must be held in place while the bolt is loosened. One trick is to wrap an old drive belt around the pulley to hold it steady — don't try this with a belt that is to go back on the car; it will be stretched or damaged.
Fig. 10: On all engines except VTEC, the belt adjuster arm must be locked in place using one of the lower cover mounting bolts
NOTE: There are two belts in this system; the one running to the camshaft pulley is the timing belt. The other, shorter one drives the balance shaft and is referred to as the balancer belt or timing balancer belt. Use a piece of chalk or a marker to place an identifying arrow on the belts. The arrow can identify the direction of rotation or the outer edge of the belts. The belts must be reinstalled so it moves in the same direction. Protect the belts from oil, coolant, etc. It's an even better idea to replace the belts at this point.
NOTE: Always rotate the crankshaft counterclockwise when viewed from the pulley end. Rotating it clockwise will cause improper adjustment and possible damage.
NOTE: Handle the tensioner carefully so the oil inside does not spill or leak. Replenish with clean engine oil if any does leak. Total capacity is 1⁄4 fl. oz. (8 ml).
Fig. 11: On VTEC engines, the tensioner must be compressed before installing it on the engine

NOTE: Both belt adjusters are spring-loaded to properly tension the belts. Do not apply any additional pressure to the pulleys or tensioners while performing the adjustment.
