7F-18 DIFFERENTIAL (REAR)
Assembling Unit
1) Place bearing outer races on their respective bearings.
Used left and right outer races are not interchangeable.
2) Install case assembly in carrier.
3) Install side bearing adjusters on their respective carrier,
making sure adjuster are threaded properly.
4) Align match marks (1) on cap and carrier. Screw in 2 side
bearing cap bolts 2 or 3 turns and press down bearing cap
by hand.
5) Tighten cap bolts (provisional torque).
Tightening torque
Bearing cap bolt (Provisional torque) (a) :
15 N·m (1.5 kg-m, 11.0 lb-ft)
6) Tighten both bearing adjusters (2) so as to obtain specified
gear backlash and at the same time, obtain preload of side
bearing.
Standard backlash
: 0.13 – 0.18 mm (0.005 – 0.007 in.)
Special tool
(A) : 09930-40120
(B) : 09930-40113
(C) : 09900-20701
NOTE:
If bearing cap does not fit tightly on carrier, side bearing
adjuster is not threaded properly. Reinstall adjuster.
NOTE:
• Be sure to apply measuring tip of dial gauge at right
angles to convex side of tooth.
• As a practical measure the following would be recom-
mended to obtain specified backlash and side bearing
preload at the same time.
– Obtain specified backlash by turning both adjusters
inward lightly.
– Tighten both adjusters further by one notch at a
time.
• Measure at least 4 points on drive bevel gear periph-
ery.
