HD-35381 | Belt tension gauge |
Check rear belt deflection:
- As part of the pre-ride inspection.
- At every scheduled service interval.
Note. Customers may purchase belt tension gauge from an authorized Harley-Davidson dealer.
Caution! Setting tension without using BELT TENSION GAUGE typically results in loose belts. Loose belts will fail due to ratcheting (jumping a tooth) which causes tensile cord crimping and breakage.
1. See Figure 1 -36. Check rear belt tension with motorcycle cold, standing upright, transmission in NEUTRAL and no rider on motorcycle.

3. Verify that the drive belt deflects 6 mm.
Note. Belt deflection window on the debris deflector is graduated in 2 mm increments.
4. If belt adjustment is necessary, see Figure 1-38. Remove snap ring (1) and loosen axle nut (2) on right side of motorcycle.

Figure 1-38. Axle adjusters: 1. Snap ring (right side); 2. Axle nut (right side); 3. Adjustment eccentric (left side)
Note. The left cam is welded to the axle and the right cam is keyed to the axle. Clockwise rotation of axle will tighten beltcounter-clockwise rotation will loosen belt.
5. Adjust belt tension on left side by turning the axle adjustment eccentric (3) until the specification in step 2 is achieved.
Warning! Do not exceed 142.4 Nm (105 ft-lbs) when tightening the axle nut. Exceeding 142.4 Nm (105 ft-lbs) may cause the wheel bearings to seize during operation, which could result in death or serious injury.
6. Tighten axle nut (2).
- a. Tighten axle nut (2) to 129.0-142.4 Nm (95-105 ft-lbs).
- b. Install snap ring (1).
