assembly.
2-1 Gear case co structio
2-2 Checki g oil li e
1. Disconnect oil line from the auto-oiler and
remove oil tank from the gear case.
2. Connect pressure tester #897803-30130 to the
oil line (A) using appropriate connector pipe (B)
(recommended outer dia. : 4 - 5 mm).
3. Apply pressure approximately 0.01 MPa
(0.1 kgf/cm2) (1.5 psi). Pressure should not drop.
If the pressure drops, leakage may be occurring at
oil cap, oil cap O-ring, oil tank, oil line, grommet,
or oil tank check valve. Check them and replace
defective part(s).
2-3 Checki g oil filter a d check valve
1. Pry out oil pipe grommet (A), and pull out oil
line and oil filter (B).
2. Wash oil filter in suitable clean solvent or
replace the filter with a new one if damaged.
3. Remove oil tank check valve (C), and clean it.
4. Check if the valve lips (D) are hardened or left
opened. Replace as required.

shaft end.
5. Tighten the bolt with wrench holding handle (B)
until the worm comes off.
2-6 I serti g worm gear
NOTE: Do ot reuse removed worm gear. Bore
of the used worm gear may be e larged a d
the worm gear may slip o sprocket shaft.
1. Screw worm gear into the worm remover (A).
2. Apply oil to the tapered side of worm gear.
3. Tap on to sprocket shaft until the worm gear
bottoms.
