4 Assembly of Pinion Shaft
As an easier method for measuring the preload,
after temporarily tightening the nut, wind the shaft
GS7W3-167 of pinion shaft with rope and pull with spring
balance. (F = 39.2 - 58.8N {4.0 to 6.0kgf, 8.8 -
13.2lbf})

1. Adjust the preload for pinion shaft within 0.39 to
0.59N•m {4 to 6kgf•cm, 28.9 to 43.4lbf•ft} (at oil
seal assembling) by tightening the nut.
Crimp the nut after adjustment.
CAUTION
2. Measure the H measurement and adjust to have H -
16mm {0.63in} = Liner Thickness with the liner
"J".
3. Placing direction of the oil seal for pinion shaft
shall be as shown in the figure. (Spring stays
inside.)
Item Thickness
0.10 {0.004}
Liner "J" 0.20 {0.008}
0.40 {0.016}
1. Make sure the backlash for the pinion gear and side
gear is within 0.10 to 0.30mm {0.004 to 0.012in}.
2. Apply adhesives equivalent to Threebond #1374 to
the locking bolt for the ring gear and tighten with
torque at 68.6 to 78.5N•m {7 to 8kgf•cm, 50.6 to
57.9lbf•ft}.
3. Place the spring pin with the slit toward as shown in
the figure. (Vertical to the shaft)
4. Apply lubricant (MOS ) to the gears and assemble
2
it.
