CONSTANT VELOCITY JOINTS
For normal operations, it is best to keep the CV joint aligned or with the
smallest joint angle possible. During turns or other short duration manoeuvres, the
maximum joint angle is 80°. When the driveline includes a CV joint on the tractor
side and a single U-joint on the implement side, the maximum recommended
angles of the U-joint are 16° at 540 min –1 and 9° at 1000 min –1 to avoid drive
irregularities.
When used at night or in poor visibility, illuminate the driveline operating
area.
Friction clutches may become hot during use. Do not touch! Keep the area
around the friction clutch clear of any material which could cause a fire and
avoid prolonged slipping of the clutch.
INSTALLATION
Always wear adequate safety equipment when performing any maintenance
or repair work.
The tractor printed on the labels on the shield tubes indicates the tractor end
of the driveline. Any torque limiter or overrunning clutch should always be
installed on the implement end.
Ensure that the driveline is securely attached to the tractor and the implement
before operating.
Check that all fixing screws are tight.
Attach the driveline guard restraints (chains). Best results are achieved when
chains are attached nearly perpendicular to the driveline guard. Adjust the
length of the chains to allow enough slack for full movement of the driveline during
turns, operation, and transport. Avoid excessive slack, which could cause the
chains to roll around the driveline.
If the length of the chain is not adjusted correctly and tension is excessive,
for example during implement maneuvers, the “S” hook will detach from the
locking ring and the chain will disconnect from the shield.
In this case, the chain must be replaced.
The “S” hook of the new chain must be inserted in the eye of the base cone and
it must be closed to prevent it from becoming disengaged, maintaining its round
shape.
Never use the safety chains to transport or support the driveline when you
have finished using it for storage. Always use the support provided on the
implement.
Clean and grease the tractor PTO and implement shaft before installing the
driveline.
Keep the driveline horizontal during handling to prevent the halves from
sliding apart, which could cause injury or damage the shielding. Use suitable
means to transport heavy drivelines.
