Lubrication of the Slip-Joint Spline

rv mm 41.02.000
  1. Wipe all old grease and dirt from the slip-joint grease fitting.
  2. Use a hand-type grease gun or a high-pressure gun with a low-pressure adaptor, to lubricate the slip-joint. Using lithium 12-hydroxy stearate grease (NLGI grade 1 or 2, with EP additives), lubricate until fresh grease appears at the pressure-relief hole in the yoke plug. Then cover the relief hole with your finger, as shown in Fig., while continuing to lubricate until fresh grease appears at the slip-joint seal. This ensures complete lubrication of the splines.

    • After grease appears, cover the pressure-relief hole while continuing to lubricate.
