Control functions TIP The spring preload setting is determined by measuring distance A, shown in the illustration. The longer distance A is, the higher the spring preload; the shorter distance A is, the lower the spring preload. Spring preload setting*: Minimum (soft): FX10 92.6 mm (3.65 in) FX10RTRS 75.4 mm (2.97 in) FX10XT 106.1 mm (4.18 in) Standard: FX10 101.6 mm (4.00 in) FX10RTRS 84.4 mm (3.32 in) FX10XT 122.1 mm (4.81 in) Maximum (hard): FX10 108.6 mm (4.28 in) FX10RTRS 91.4 mm (3.60 in) FX10XT 132.1 mm (5.20 in) * Distance A changes 1.5 mm (0.06 in) with each full turn of the adjusting nut. 3. Tighten the locknut to the specified torque. NOTICE: Always tighten the locknut against the adjusting nut, and then tighten the locknut to the specified torque. [ECS00860] Tightening torque: Locknut: 42 Nm (4.2 m·kgf, 30 ft·lbf) Rear torsion springs EWS00750 To increase the spring preload and thereby harden the suspension, turn the adjuster in direction (a). To decrease the spring preload and thereby soften the suspension, turn the adjuster in direction (b). (a) (b) 1 1. Spring preload adjuster Spring preload setting: Minimum (soft): S Standard: M Maximum (hard): H ESU13631 Adjusting the air pressure of the center shock absorber and the rear shock absorber (FX10M53S/FX10M62S) A shock absorber pump is provided with your snowmobile to adjust the air pressure of the shock absorbers. This pump is equipped with an air pressure gauge. One side of the gauge has a low-pressure meter and the other side of the gauge has a high-pressure meter. Use the low-pressure meter to adjust the center shock absorber and the high-pressure meter to adjust the rear shock absorber. WARNING The left and right spring preloads must be adjusted to the same setting. Uneven settings can cause poor handling and loss of stability. 27
