Valve Lash (Clearance) Adjustment - Suzuki Grand Vitara 2011 Manual

Valve Lash (Clearance) Adjustment

1) Measure valve lash (clearance) referring to "Valve
Lash (Clearance) Inspection: For F9Q Engine".
2) Remove tappet referring to "Camshaft and Tappet
Removal and Installation: For F9Q Engine".
3) Using dial gauge (1), magnetic stand (2) and surface
plate (3), measure thickness of removed tappet.
4. Tappet
4) Determine replacement tappet by calculating
thickness of new tappet with the following formula.
Intake side:
A = B + C – 0.200 mm (0.00787 in.)
Exhaust side:
A = B + C – 0.400 mm (0.01575 in.)
A: Thickness of new tappet
B: Thickness of removed tappet
C: Measured valve lash (clearance)
Example of intake side:
When thickness of removed tappet is 7.825 mm
(0.30807 in.), and measured valve lash (clearance)
is 0.275 mm (0.0108 in.):
A = 7.825 mm (0.30807 in.) + 0.275 mm (0.0108 in.)
– 0.200 mm (0.007382 in.) = 7.900 mm (0.31102 in.)
Calculated thickness of new tappet = 7.900 mm
(0.31102 in.)
5) Select new tappet with a thickness as close as
S6JB0A1434004 possible to calculated value.
