b. If it is necessary to increase the final gear  backlash by more than 0.2 mm (0.008 in), re-
duce the ring gear shim thickness by 0.2 mm 
(0.008 in) for every 0.2 mm (0.008 in) in-
crease of thrust washer thickness.
c. If it is necessary to reduce the final gear back-
lash by more than 0.2 mm (0.008 in), in-
crease the ring gear shim thickness by 0.2 
mm (0.008 in) for every 0.2 mm (0.008 in) de-
crease of thrust washer thickness.
TIP
Be sure to use only one thrust washer to...

 The stopper bolt has left-hand threads. To 
tighten the stopper bolt, turn it counter-
clockwise.
Apply LOCTITE ® onto the stopper bolt.
4. Measure: Ring-gear-to-stopper-bolt clearance
TIP
If the ring-gear-to-stopper-bolt clearance is out 
of specification, repeat the above procedure.

b. To find final drive pinion gear shim thickness  “A” , use the following formula:
Where:
a = 85.00
b = a numeral on the final gear case, to be di-
vided by 100 and added to “ 84”.
Example:
If the final gear case is marked  “52”:
Round off to the hundredths digit and select 
the appropriate shim(s).
TIP
In the example above, the calculated final drive 
pinion gear shim thickness is 0.28 mm (0.011 
in). The chart instructs you to round off the 8 to 
10. Thus, you should use a 0.30...

TIP
In the example above, the calculated ring gear 
shim thickness is 0.52 mm (0.0205 in). The chart 
instructs you to round off the 2 to 0. Thus, you 
should use a 0.50 mm (0.0197 in) ring gear 
shim. Shim sizes are supplied in the following thick-
nesses.
