Bevel Gear Case and Front Wheel Case Bushing
1. Visually inspect the DX bushings for signs of wear or damage.
(The DX bushing tends to show concentrated wear.)
2. If the DX bushing is worn beyond the alloy portion "L" , replace
it.

Backlash of Bevel Gear in Bevel Gear Case
1. Set a dial indicator (lever type) on the shaft (Kingpin).
2. Move the shaft (Kingpin) by hand and measure the
circumferential play of the shaft.
3. Calculate the backlash from the ratio of the shaft diameter to the
gear diameter. (Backlash = Play × 2)
4. If the backlash exceeds the allowable limit, adjust with the shims
(1).
