Lay LUCAS on the side of table with nothing blocking the shaft underneath. The round end of
spring should be facing up according to the picture below.
Knock the Spring out with a Hammer and a Mandrel or similar tool. Tap the spring downwards
with the mandrel and hammer until it falls loose.
When the Spring is removed from the Angle Shaft, turn the device over so the press
fitted side is facing up. Using the metal Pin or similar tool and Hammer, push the
bottom, non-press-fitted Angel Shaft out of Support Leg. Always knock out the non-
press fitted Angle Shaft first.
