DISASSEMBLY OF CV JOINT SHIELD
Unscrew the shield cone screws.
Slide off the shield cone. For size 8, the CV shield cone is interlocked with the
base cone, must be disengaged before disassembly.
Disengage the retaining spring, leaving it inserted in one of the two holes of
the bearing ring to avoid losing it.
Spread apart the shield support rings and remove them from their grooves.
ASSEMBLY OF CV JOINT SHIELD
Grease the groove and fit the shield bearing ring.
Install the bearing ring on the CV body with the bosses facing the inner yoke.
The ring is equipped with a grease fitting, which is utilized only for 50° constant
velocity joints. Disregard the grease fitting of the bearing for 80° joint shields.
Connect the retaining spring to the two edges of the bearing ring.
Insert the shield cone, aligning the radial holes with the bearing ring bosses.
Only for 50° constant velocity joints: check that the radial holes of the shield
cone are aligned with the holes in the bearing ring bosses and that the additional
hole in the shield cone is aligned with the grease fitting in the bearing ring.
Tighten the 6 flange head screws of the protection strip. Refit the fixing plate
for the chain. The use of an electric screwdriver is not recommended.
HOW TO SHORTEN THE DRIVE SHAFT
BP C.H.M. advises against altering its products. If modifications are required, we
recommend that you consult your implement dealer or a qualified service center
before proceeding. If the driveline is too long adopt the following procedure.
Remove the shielding.
Shorten the drive tubes by the required length.
Telescoping tubes must always overlap by at least 1/2 of their length in normal
operation and at least 1/3 of their length in all working conditions.
During maneuvers, when the driveline is not rotating, the telescoping tubes must
have a suitable overlap to maintain the tubes aligned and allow then to slide freely.
Carefully deburr the ends of the tubes with a file and remove all filings from
the tubes.
Shorten shield tubes one at time by cutting the same length that was cut
from the drive tubes.
