Lubrication
NOTICE
Apply grease to the sector shaft with a hand-type
grease gun only. Use of a high-pressure power
grease gun will supply grease too quickly and
could affect the high pressure seal, contaminating
the hydraulic fluid.
Using a hand-type grease gun, apply NLGI Grade 2
or 3 multipurpose chassis grease until it starts to
come out past the sector shaft seal. See
46–05 Drag Link Lubrication
