• Measure the side clearance with a precision
straight edge and a feeler gauge.
Clearance
Standard : 0.03 mm–0.09 mm
(0.0011 in–0.0035 in)
Limit : 0.15mm (0.0059 in)

Reassembly
1. Install drive gear (11).
2. Install driven gear (10).
3. Install oil pump cover (9) and first, loosely tighten all
of the attaching screws. Next, tighten the attaching
screws to the specified torque.
Torque : 10 N⋅m (1.0 kg⋅m/7 lb ft)
After installation, check that the gear rotates
smoothly.
4. Install relief valve (8) and apply engine oil to the
relief valve and spring (7).
5. Install spring (7).
6. Install the plug (6).
Torque : 8 N⋅m (0.8 kg⋅m/6 lb ft)

7. Install oil pump assembly (5).
• Carefully remove any oil from the cylinder body
and the pump. Apply sealant (TB–1207B or
equivalent) to the pump fitting face as shown in
illustration. Take care that sealant is not applied
to oil port surfaces. The oil pump assembly
must be installed within 5 minutes after sealant
application to prevent premature hardening of
sealant.
CAUTION: Do not apply an excessive amount of
sealant to the contact surface. Applying too much
sealant will overflow the contact surfaces. This
could cause serious damage to the engine.
• Attach oil pump assembly to cylinder body.
• Tighten the oil pump fixing bolts.
Torque : 25 N⋅m (2.6 kg⋅m/18 lb ft)
