Suzuki Grand Vitara JB416 / JB420. Manual — part 115
1D-128 Engine Mechanical: For J20 Engine
Oil Pump Chain
Check oil pump chain for wear or damage.
Flywheel
• If ring gear is damaged, cracked or worn, replace
flywheel.
• If the surface contacting clutch disc is damaged, or
excessively worn, replace flywheel.
• Check flywheel for face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.
Limit on runout
0.2 mm (0.0078 in.)
Cylinder Block
• Distortion of gasketed surface
• Using straightedge and thickness gauge, check
gasketed surface for distortion and, if flatness
exceeds its limit, correct It.
Flatness Limit
0.06 mm (0.0024 in.)
Honing or reboring cylinders
1) When any cylinder needs reboring, all other
cylinders must also be rebored at the same time.
Oversize piston specification
2) Using micrometer, measure piston diameter.
3) Calculate cylinder bore diameter to be rebored as
follows.
D = A + B – C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 – 0.04 mm (0.0008 –
0.0015 in.)
C: Allowance for honing = 0.02 mm (0.0008 in.)
4) Rebore and hone cylinder to calculated dimension.
NOTE
Before reboring, install lower crankcase and
tighten to specification to avoid distortion of
bearing bores.
5) Measure piston clearance after honing.
Check Valve
Check check valve for clogging and ball for being stuck.
