Driveline Installation
Refer to Figure 1-9:
DANGER
!
To avoid serious injury or death:
Make certain driveline yokes are securely fastened at each
end. A loose yoke can work free allowing the driveline to
rotate uncontrollably causing implement damage and bodily
injury or death to anyone nearby.
1. Unsnap gearbox shield access doors (#23) and
rotate doors open.
2. Remove protective sleeve from gearbox input shaft.
3. Remove nut (#26), lock washer (#25), and clamp
bolt (#24) from slip-clutch end of driveline (#21).
4. Slide slip-clutch end of driveline (#21) onto gearbox
input shaft until hole in yoke aligns with notch in shaft.
IMPORTANT:
The drivelines must be lubricated
before putting them into service. Refer to
