(4) Reassembly of the Oil Felt:
To replace the Oil Felt [79], follow the procedures described below.
Slender-Tipped Rod
or Steel Wire
Felt Holder (C) Ass'y [77]
1) As illustrated in Fig. 12, fit the wide end of the Oil Felt [79] into the oiling hole, and push it through with a
slender-tipped rod or steel wire.
2) When approximately 5 mm (0.2") of the Oil Felt [79] has been pushed through into the oil tank, grasp the
tip with pliers or a similar tool, and pull it into the oil tank so that 10 --- 11 mm (0.39" --- 0.43") remains
protruding into the crank case chamber side, as illustrated in Figs. 12 and 13.
3) As illustrated in Fig. 14, mount the Felt Holder (C) Ass'y [77] so that its recess is engaged with the
protrusion on the inside of the oil tank chamber of the housing.
4) Assemble the Connecting Rod Ass'y [38] onto the Crank Shaft [37], rotate the Crank Shaft by hand, and
confirm that the Oil Felt [79] comes into contact with the Seal Lock Hex. Socket Hd. Bolt M8 x 16 [35]
which fixes the Connecting Rod Ass'y [38]. (Fig. 15)
5) After mounting the Felt Holder (C) Ass'y [77], the Oil Felt [79] must be bent toward the Front Cover [7]
side as illustrated in Fig. 15.
