DRIV
Because shims can only be selected in 0.05
mm increments, round off hundredths digit
and select appropriate shim(s).
In the example above, the calculated shim
thickness is 0.51 mm. The chart instructs
you, however, to round off the 1 to 0, then
shim thickness is 0.50 mm.
Shim selection Î
●When the crankcase, driven pinion gear,
reverse gear, bearing housing and/or mid-
dle driven shaft are replaced, be sure to
adjust the middle driven shaft shim Î.
●To find reverse gear shim thickness “D”
use following formula:
j= The stamped number on the bearing
hauging is substracted from “1”.
c= The stamped number on the crankcase
is added to from “110”.
e= Bearing (driven pinion gear) width
“13.00”.
k= The stamped number on the driven
pinion gear (forward gear) is sub-
stracted from “14.5”.
l= The stamped number on the middle
driven shaft is either added to or sub-
stracted from “80.5”.
