Shorten drive tubes by the required length. In normal conditions, telesco-
76
ping tubes must always overlap by at least a 1/2 of their length. During ma-
noeuvres, when the driveline is not rotating, the telescoping tubes must have a
suitable overlap to maintain the tubes aligned and allow then to slide properly. If
the driveline is fitted with a single chain restraint system (splined inner tube), the
tubes can be shortened by a limited amount (normally no more than 70 mm) to
avoid eliminating the splined ring connecting the two shield tubes. If the driveline
is fitted with a greasing system incorporated in the inner drive tube, the tubes
can be shortened by a limited amount to avoid damage to the lubrication system.
Carefully measure and shorten each drive tube equally.
Carefully deburr the ends of the tubes with a file and remove any chippings
77
from the tubes.
Shorten shield tubes one at time by cutting the same length that was cut
78
from the drive tubes. If the driveline is equipped with Single Chain Restraint
System, shortening the driveline will involve removal of the plastic ring which con-
nects the shield tubes. If it is necessary to remove this collar, ADD A RETAINING
CHAIN TO THE TRACTOR SIDE OF THE DRIVELINE SHIELD.
Grease the internal drive tube.

Reassemble the shielding on the driveshaft.
Check the length of the drive shaft at the minimum and maximum positions
80
of the machine.
Telescoping tubes must always overlap by at least a 1/2 of their length.
During manoeuvres, when the driveline is not rotating, the telescoping tubes must
have a suitable overlap to maintain the tubes aligned and allow then to slide properly.
