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.
