2. Check DES Hand Wheel Assembly:
a. O-rings around the outside rim of Hand Wheel (Royce P/N 2439); (1) left
and (1) right.
b. O-rings inside the Hand Wheel Bearing Block (Royce P/N 2440); (3) in the
left side block and (3) in the right side block.
c. Replace O-rings if cracked or loose. DO NOT LUBRICATE O-RINGS!!!
NOTE: Do not tighten Set Screws so tight that motion becomes hard and lumpy.
This will break the O-Ring Pressure Bearing.
