the new seal into the gland so the lips are toward
the small end of the gland.
3. Lubricate a new wiper with clean hydraulic oil. Insert
the new wiper into the gland so the lips are toward
the large end of the gland.
4. Lubricate a new backup ring with clean hydraulic
oil. Insert the new backup ring into the groove on
the outside of the gland so the flat side is toward
the large end of the gland.
