E xam ple: S election of the drive pinion gear
shim ;
Shim Thickness =
D istance “A ” -
D istance “B ”
If the drive pinion gear is stam ped “03” (plus
(+ 03) is im plied here since only the m inus
(-) designations are stam ped alongside the
num bers), then:
“A” = 53 -- 0.03
= 54.53
N O TE:
A ll stam ped num bers are in hundredths of a
m m .
If the left-side-rear of the upper crankcase
is stam ped
then:
= 53 + 0.95
= 53.95
Therefore:
T = A - B
54.53 53.95
= 0.58 m m
calculated shim thickness is 0.58 m m .
Because shim can only be selected in 0.05
m m increm ents, use the follow ing chart to
round off the hundredths digit of the calcu-
lated thickness and selest the appropriate
shim ,
the above exam ple, the calculated
shim thickness of 0.58 m m is rounded off to
0.60 m m . Therefore, you m ay choose either
4
0.15 m m shim s, 2 0.30 m m shim s, or
1
0.30 m m and 2
0.15 m m shim s as
selected from the shim thickness chart
below . Shim size are supplied in the follow -
ing thicknesses:
