12.6.1 Replacement of change-of-direction belt WR 870 Honda
(Fig. 24 - Replacing the direction change belt)
12.6.2 The clockwise V-belt / toothed belt (internal combustion engine only)
If necessary, loosen the tensioning screw on the top of the housing of the V-belt /
timing belt, so that you can lever out the toothed belt from the groove of the
drive disc. Now it can be replaced with a new toothed belt.
Drive belt label: Ax38/X13x965Li
Please only use original toothed belts from authorised dealers!
Make sure that the V-belt / toothed belt runs with its teeth outwards over the
guide roller and the drive pulley. The toothed side should engage in the groove
of the motor drive pulley. When adjusting the tension, please use the tensioning
screw on the top of the housing.
The toothed belt may only be stretched so far that power
transmission only occurs when the lever to change the
direction of rotation is pulled and the connected sweeping
direction guide roller is affected.
In the neutral position of the guide roller, the V-belt /
timing belt should be able to slide over the guide roller and
drive pulley.
