With assistance, lift the front arm out of the lower main shaft
clamp and upper arm, gently set the front arm on a flat work
surface.
Note: On April 3, 2013 the front arms and cams were redesigned so that
the cams are pressed onto the front arm axle. If you are servicing a
AMT12 that has this configuration, skip the cam removal steps.
Important: Before removing the cams, note the orientation on the front arm.
1
Mark the sides of the inside and outside cams with a notation to
indicate the sides facing away from the front arm tube. For example,
mark the outside cam with a "O" and the inside with a "I".
