9-5 9 ADJUSTING REAR ARM COUPLER NOTE: The couplers are installed in the 2-groove The rear arm coupler provides advantages over the standard suspension. First, with the coupler system, ski lift under accelera- tion is greatly reduced which provides improved han- dling. Second, when riding through rough terrain, the rear suspension arm receives some needed assistance from the front arm shock and spring. This happens as the rear arm is fully collapsed and locked up by the coupler blocks. The front arm then starts to collapse the shocks and spring which assist the rear springs. The result is a smoother ride for the operator. Each of the coupler blocks has four positions (notched grooves on the outside surface of the block). When changing the block position, change both to the same groove number. To make coupler adjustment, follow the procedure below. 1. Using a 9/16-in. wrench, loosen the two cap screws that secure the coupler blocks to the inside of the suspension rails. 2. Rotate the coupler blocks to the desired position making sure both are set the same. 738-230B NOTE: When setting the block, the chosen groove 738-230C 3. Place a 4-in. block of wood under the rear of the suspension just in front of the rear idler wheels. This will assist in collapsing the suspension. 4. Collapse the rear suspension until the rear arm is firmly against the coupler blocks. This will align the two blocks squarely with the arm. While in this position, tighten the two cap screws securing the blocks. ADJUSTING REAR ARM COUPLER The rear arm coupler provides advantages over the standard suspension. First, with the coupler system, ski lift under acceleration is greatly reduced which provides improved handling. Second, when riding through rough terrain, the rear sus- pension arm receives some needed assistance from the front arm shock and spring. This happens as the rear arm is fully collapsed and locked up by the coupler blocks. The front arm then starts to collapse the shocks and spring which assist the rear springs. The result is a smoother ride for the operator. If additional coupler action is desired, the coupler blocks can be set to the number 2 or 3 position. Each of the coupler blocks has three positions numbered on the inside surface of the block. When changing the block position, change both to the same number. To make the coupler adjustment, follow the procedure below. 1. Using an 8 mm Allen-wrench, loosen the two cap screws that secure the coupler blocks to the inside of the suspension rails. 2. Rotate the coupler blocks to the desired position making sure both are set the same. 738-230A 3. Place a 4-in. block of wood under the rear of the suspension just in front of the rear idler wheels. This will assist in collapsing the suspension. 4. Collapse the rear suspension until the rear arm is firmly against the coupler blocks. This will align the two blocks squarely with the arm. While in this position, tighten the two cap screws securely. |
