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.
