5.50. After the belt is removed, the driven pulley can
be removed: See Figure 5.50.
• Take the bolt and washer that secure the pulley
onto the transaxle input shaft completely off
using a 12 mm wrench.
• Slide the pulley off of the input shaft. It may be
necessary to carefully pry on the pulley hub.
• There is a key between the pulley and the input
shaft, and a spacer between the pulley and the
shoulder on the input shaft.
5.51. If the driven pulley does not function properly,
replace it as a complete unit.
5.52. On installation:
• Apply a small amount of anti-seize compound to
the input shaft.
• Confirm that the spacer and key are properly
positioned. The chamfered side of the spacer
should face the shoulder on the crankshaft.
• Slip the driven pulley all the way onto the input
shaft, and seat it against the spacer.
• Apply a small amount of thread locking com-
pound such as Loctite 242 (blue) to the threads
of the bolt.
• Secure the pulley to the input shaft with the bolt
and washer. Tighten the bolt to a torque of: 24 ft-
lb (32 N-m).
5.53. Key points to inspect on the driven pulley are the
ramp surfaces on the cams, and the polymer
buttons that ride against the ramps.
