FREE-PLAY



1600 and 2000 Models

On 1600 and 2000 models, the free-play of the thrust rod at the release lever is adjusted at 8,000 mile (13,000 km) intervals. Loosen the locknut and turn the nut until 0.1-0.13 inches (3.0-3.5mm) clearance exist between the release lever and the adjustment nut on the thrust rod. Tighten the locknut.

Except 1600 and 2002 Models

The 1600 and 2002 vehicles are the only models covered by this guide to utilize a cable clutch actuating system. All other models use a hydraulic system for which no free-play adjustments are necessary or possible.
