Ensure work area and all components are clean before reassembling trim cylinders.

NOTE: Before reassembly, lubricate all internal parts with power trim and steering fluid or
SAE 10W-30 or 10W-40 motor oil.
DO NOT clamp center section of trim cylinder during reassembly. If clamping of cyl-
inder is necessary, clamp cylinder on front mounting flange.

may act as an insulator and cause poor electrical continuity between cap and cylin-
der which could cause a corrosion problem.
