ALIGNING THE MIDDLE GEAR

NOTE:
Aligning the middle gear is necessary when any
of the following parts are replaced:
S Crankcase
S Middle drive shaft
1. Select:
S middle drive gear shim(-s) 1
NOTE:
Select the middle drive gear shim(-s) 1 by cal-
culating the middle drive gear shim thickness
and then measuring the middle gear backlash.
a. Position the middle drive gear with the ap-
propriate shim(-s) 1 that has had its respec-
tive thickness calculated from information
marked on the crankcase and the end of the
middle drive gear.
b. To find middle drive gear shim thickness
"A", use the following formula.
Middle drive gear shim thickness
"A" = a – c
a ="43.00"
b =a numeral on the upper crankcase near
the main bearing selection numbers and
which is added to the nominal size "42"
Example:
a is 43.00
If the upper crankcase is marked "46" b
c is 42.46 (i.e., 42.00 + 0.46 =42.46)
"A" = 43.00 – 42.46 = 0.54
Round off to the hundredths digit and select
the appropriate shim(-s).
NOTE:
In the above example, the calculated number
is 0.54. The chart instructs you to round off
the 4 to 5. Thus, the shim thickness is 0.55
mm.
