Dual-mass Flywheel (MTX)/ Drive Plate (ATX) Installation Bolt Disassembly Note
Dual-mass flywheel installation bolt (MTX)
1. Hold the crankshaft using the
SST (49 E011 1A0).
2. Loosen the bolts uniformly and gradually in the
order shown in the figure.
Note
• If the bolt installation holes are not
positioned properly, perform the following
procedure:
(1) Install the
SST (49 S120 710) to the dual-
mass flywheel.
(2) Rotate the dual-mass flywheel (secondary
flywheel side) using the
SST (49 S120 710).
(3) When the bolt installation holes are positioned
properly, hold the position and remove one of
the bolts.
(4) After removing the bolt, set up the
SST (49
G033 102) to lock the dual-mass flywheel
(secondary flywheel side) against rotation.
Warning
• If all of the bolts are removed without
locking the dual-mass flywheel
(secondary flywheel side) against
rotation, the dual-mass flywheel (primary
or secondary flywheel side) may rotate,
resulting in injury. Therefore, always set
up the SST (49 G033 102).
• When the bolts are removed from the
dual-mass flywheel, always cover the bolt
holes using tape. If the SST (49 G033 102) is removed while the operator’s finger is inserted in the
bolt hole, the dual-mass flywheel may rotate and the operator could be injured.
(5) Remove the remaining bolts.
Drive plate installation bolt (ATX)

Dual-mass Flywheel Disassembly Note (MTX)
Note
• When reusing the dual-mass flywheel, do not remove the SST (49 G033 102) locking the dual-mass
flywheel (secondary flywheel side) against rotation.
Rear Oil Seal Disassembly Note
1. Cut the oil seal lip using a utility knife.
2. Remove the oil seal using a flathead screwdriver
with the tip protected by a clean cloth to prevent
damage to the oil seal sliding part of the
crankshaft.

Pilot Bearing Disassembly Note
Note
• The pilot bearing does not need to be removed unless you are replacing it.
1. Use the
SST to remove the pilot bearing.
Connecting Rod Cap Disassembly Note
1. Before removing the connecting rod cap, inspect
the connecting rod side clearance. (See 01-10-35
CONNECTING ROD CLEARANCE
INSPECTION.)
2. The removed connecting rod caps are to be kept
so that they can be assembled to the same
positions and in the direction as before removal.
Connecting Rod Bearing Disassembly Note
1. The removed connecting rod bearings are to be kept so that they can be assembled to the same positions and
in the direction as before removal.
Piston, Connecting Rod Disassembly Note
1. Before removing the piston and connecting rod, remove the carbon in the cylinder.
2. Before removing the piston and connecting rod, inspect the oil clearance at the large end of the connecting rod.
