MAINTENANCE
The Driveline Integral Shields should not become dented or otherwise damaged. The Integral Shield Assembly
has a Nylon Bearing at each end and should turn freely. This nylon bearing should require lubrication every 40
hours. To remove the Integral Shields for replacement or repair, turn the three Nylon Nuts 1/4 turn in the Shield
Slots of the Cone and Tube and remove them. Slip the Shield Cone Assembly off inner section of the Driveline.
Install the new or repaired Shield on the Driveline. Place the split Nylon Bearing over the Driveline Housing of
Shaft against the Yoke and in the Bearing groove. Install shield over the Housing so the Nylon Bearing fits into
the Shield Bearing Retainer. Align a slot in the Shield Cone with one of the slots in the Shield. Put one of the
Nylon Nuts back in through the aligned slots and turn until it is perpendicular to the slots. Add the other two
Nylon Nuts.
Make certain that the Driveline Integral Shields are free to telescope and rotate around the
driveline without binding.
SHEAR PIN YOKE LUBRICATION
Yoke is supplied with a grease fitting to lube
between gearbox shaft and yoke. This allows yoke
to spin freely on gearbox shaft when pin shears.
Failure to lube may cause yoke to gall and spin
weld to shaft. Adding even small amounts of grease
will greatly prolong life of yoke. The shear bolt (1/2”
x 2-3/4”) MUST BE a Grade 2 to ensure that it
shears when high torque load is encountered.
