Determine The Replacement Adjusting Shim Size Byfollowing–The Formula Or Chart - Toyota 22R-E Service Manual

ENGINE – ENGINE MECHANICAL
HINT: For easy removal of the shim, When setting SST
8, set it on the lifter so there is a wide space in the
removal direction.*
Remove the adjusting shim with a small screw–
driver and magnetic finger.
(b) : Determine the replacement adjusting shim size by
following–the Formula or Chart:
Using a rnicrometer, measure – the thickness of
the removed shim.
Culculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ........... Thickness of removed shim
A ............. Measured valve clearance
N ........... Thickness of new shim
Intake:
N = T + (A – 0.23 mm (0.009 in.))
Exhaust:
N = T + (A – 0.27 mm (0.011 in.))
Select a new shim with a thickness as close as
possible to the calculated value.
HINT: Shims are available in twenty–five sized in
increments of 0.05 mm (0.0020 ire:), from 2.20 mm
(0.09B4 in.) to 3.40 mm (0.1299 in.).
(c) Install a new adjusting shim.
Place a new adjusting shim on the valve lifter.
Using SST (A), press down the valve lifter and
remove SST (B).
