Inspection and Repair
CAUTION: Make necessary correction or parts
replacement if wear, damage or any other abnormal
conditions are found during inspection.
Relief Valve (8)
Check to see that the relief valve slides freely.
The oil pump must be replaced if the relief valve does
not slide freely.
Replace the spring and/or the oil pump assembly (5) if
the spring is damaged or badly worn.

Body (14) and Gears (10, 11)
The pump assembly must be replaced if one or more of
the conditions below is discovered during inspection.
Badly worn or damaged driven gear (10).
Badly worn drive gear (11) driving face.
Badly scratched or scored body sliding face (14) or
driven gear (10).
Badly worn or damaged gear teeth.
Measure the clearance between the body and the driven
gear with a feeler gauge.
Standard : 0.10 mm–0.18 mm
(0.0039 in.–0.0070 in)
Limit : 0.20mm (0.0079 in)
051RS004
Measure the clearance between the drive gear and
driven gear with a feeler gauge.
Standard : 0.11 mm–0.24 mm
(0.0043 in–0.0094 in)
Limit : 0.35mm (0.0138 in)
051RS003
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)

Oil Strainer
Check the oil strainer for cracking and scoring. If cracking
and scoring are found, the oil strainer must be replaced.

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 Nꞏm (1.0 Kgꞏm/89 lb in)
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 Nꞏm (0.8 Kgꞏm/69 lb in)
051RS007
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 before the sealant
hardens.
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 Nꞏm (2.5 Kgꞏm/18 lbꞏft)
