Using SST (A), press down the valve lifter and place
SST (B) between the camshaft and valve lifter
flange. Remove SST (A).
SST 09248−06020, 09248 −55050 (09248−05510)
HINT:
Apply SST (B) at slight angle on the side marked with ”11”,
at the position shown in the illustration.
When SST (B) is inserted too deeply, it will get pinched by
the shim. To prevent it from being stuck, insert it shallowly
from the outside of the cylinder head, at a slight angle.
Remove the adjusting shim with a small screwdriver and
magnetic finger.
(b) Determine the replacement adjusting shim size by follow- ing the Formula or Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate 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 − 0.20 mm (0.008 in.))
Exhaust: N = T + (A − 0.30 mm (0.012 in.))
Select a new shim with a thickness as close as pos-
sible to the calculated value.
HINT:
Shims are available in 17 sized in increments of 0.05 mm
(0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 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 re-
move SST (B).
SST 09248−06020, 09248 −55050 (09248−05510)
(d) Recheck the valve clearance.

REPLACEMENT
1. REPLACE VALVE GUIDE BUSHINGS
(a) Gradually heat the cylinder head to 80 − 100°C (176 −
212 °F).
(b) Using SST and a hammer, tap out the guide bushing. SST 09201 −10000 (09201 −01070), 09950 −70010
(09951 −07100)
(c) Using a caliper gauge, measure the bushing bore diame- ter of the cylinder head.
(d) Select a new guide bushing (STD or O/S 0.05).
If the bushing bore diameter of the cylinder head is greater than
11.513 mm (0.4533 in.), machine the bushing bore to the follow-
ing dimension: 11.542 − 11.563 mm (0.4544 − 0.4552 in.)
If the bushing bore diameter of the cylinder head is greater than
11.563 mm (0.4552 in.), replace the cylinder head.
(e) Gradually heat the cylinder head to 80 − 100°C (176 −
212 °F).
(f) Using SST and a hammer, tap in a new guide bushing un-
til it protrudes 8.2 − 8.6 mm (0.323 − 0.339 in.) from the
cylinder head.
SST 09201 −10000 (09201 −01070), 09950 −70010
(09951 −07100)
(g) Using a sharp 7 mm reamer, ream the guide bushing to obtain the standard specified clearance (See page
EM−40 ) between the guide bushing and valve stem.

(h) Install the connecting rod cap with the 2 nuts (See page EM−103 ).
NOTICE:
Do not turn the crankshaft.
(i) Remove the 2 nuts and connecting rod cap (See proce-
dure (b) and (c) above).
(j) Measure the Plastigage at its widest point. Standard oil clearance:
STD0.032 − 0.050 mm (0.0013 − 0.0020 in.)
U/S 0.250.033 − 0.073 mm (0.0013 − 0.0029 in.)
Maximum oil clearance: 0.10 mm (0.0039 in.)
If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, grind or replace the crankshaft.
HINT:
If using a standard bearing, replace with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers im-
printed on the connecting rod and crankshaft, then selecting
the bearing with the same number as the total. There are 5 sizes
of standard bearings, marked ”2”, ”3”, ”4”, ”5” and ”6” according-
ly.
