DRIVELINE CAT 4 SAFETY SHIELD
To remove the main inner driveline shield, Remove the locking screws. Align the bearing tabs with the cone
pockets. FIGURE Mnt-0026. Remove the half-guard and remove the bearing ring. FIGURE Mnt-R-0012.
Inspect the driveline shield for worn areas or cracks. If the shield has any dents or cracks, replace the Shield.
While the Shields are off, examine the Driveline for signs of abnormal wear, bent or twisted shafts, or cracks in
the shafts or tubes. Check to see that the Drivelines telescope easily. If the Drivelines do not telescope
properly or show signs of abnormal wear, the shaft should be repaired or replaced.
DRIVELINES
Many of the equipment components are HEAVY (70 lbs or greater) and Special Lifting
Procedures are recommended. Use lifting assistance such as mechanical assistance, two
people, and proper lifting techniques when connecting or installing the driveshaft to reduce
the possibility of back injuries.
The Drivelines and U-Joints should be inspected each morning before the mower is started.
The U-Joint on the Driveline undergo extreme forces when the unit is turning or when the Wings are being
raised. It is important that the U-Joints be greased per schedule before the unit is started. The U-Joints are
located at each end of the Center and Wing Drivelines. The U-Joint assemblies are accessible by rotating the
Driveline Safety Shield until the hole in the Shield matches up with the Grease Fitting. Lubricate all fittings with
a good quality Lithium Soap compatible E.P. grease meeting the N.L.G.I. #2 specifications and containing no
more than 1% Molybdenum Disulfide. An E.P. grease meeting the N.L.G.I. #2 specifications and containing 3%
Molybdenum Disulfide may be substituted in the telescoping members only. Inspect the U-Joint for wear by
holding the shaft on one side of the U-Joint while trying to rotate the shaft on the other side of the U-Joint. If
there is noticeable movement in the Driveline replace the U-Joint before it causes severe damage to the
Driveline.
