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 maneuvers, the

maximum joint angle is 50°, 70° (Constant Velocity Joint 652) or 80° according to

the design of the CV joint. 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

-1

and 9° at 1000

-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 stamped on the shield 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.

If the length of the chain with device for separation from the base cone is

not adjusted correctly and chain tension increases excessively, for example

during implement maneuvers, the spring hook will detach from the locking ring and

the chain will disconnect from the shield.

In this case, the chain is easily reconnected as described in the following procedure.

Open the retaining ring, unscrewing the screw and moving the plate.

Insert the chain in the locking ring and reposition the plate.

Close the plate by means of the screw.
