Disassembling the unit:
 Remove bolts and
 Lift up the side of the cam slide first to remove the bolts.
 Disassembly is completed when the bolt is removed.
Reassembly
 Position the side first,
then partially tighten the and bolts. Then press
from the direction and fully tighten the bolts.
Note: When re-assembling, apply grease to the sliding surface.

Disassembled view of under cam unit

MUC50-0°·5°·10°·15°
Disassembling the unit:
 Remove bolts and
 Lift up either the or side of the cam slide to remove the bolts.
The spring part can be removed when the side is free.
Disassembly is completed when the bolt is removed.
Reassembly
 First securely tighten bolt ,
 then position the side.
 After bolts and are partially tightened,
 then if the side is free, the spring part can be installed from the rear.

Push from the direction and fully tighten the bolts.
Note: For the following reasons, grease should be applied to the sliding surface when reassembling.
   Smoothing of the sliding surface
   Preventing trouble with the sliding surface
   Preventing corrosion of the sliding surface
   Preventing intrusion of foreign substances into sliding surface
   Lubricated grease is recommended(example: Molybdenum Paste 300).
