BELT TENSION GAUGE
HD-35381-3
1

The inner tooth surface of the secondary belt has a thin coating of polyethylene lubricant. During initial operation, this coating will wear off as it is burnished into the belt fabric. This is a normal condition and not an indication of belt wear.
Belt tension is set at the factory and should be checked after the first 1000 miles (1600 kilometers) and at regular intervals thereafter.
See Figure 1 and Table 1. With 10 PSI in the rear shocks and the rear wheel on the ground and the motorcycle on its jiffy stand, use the BELT TENSION GAUGE (Part Number:HD-35381-3) to apply 10 lbs. (4.5 kg) of force at the midpoint of the bottom belt strand. Belt deflection should be 1/4-5/16 in. (6.3-7.9 mm) at the loosest spot at room temperature with transmission in neutral. If belt tension adjustment is necessary, see a Harley-Davidson dealer or follow the instructions given in the applicable Service Manual.
Check rear brake caliper position on rear brake disc. Disc should run true within brake caliper.
WARNING
Be sure wheel and brake caliper are aligned. Riding with a misaligned wheel or brake caliper can cause the brake disc to bind and lead to loss of control, which could result in death or serious injury. (00050a)
