Pinion Gear Height

WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

If the hypoid gear set has been replaced, select the pinion height adjusting washer.

Use the formula below to calculate pinion height adjusting washer thickness.
Washer selection equation:

T = T0 + (t1 - t2)

T: Correct washer thickness

T0 : Removed washer thickness

t1 : Old drive pinion head letter "H x 0.01"

("H": machined tolerance 1/100 mm x 100)

t2 : New drive pinion head letter "H x 0.01"

("H": machined tolerance 1/100 mm x 100)

Example:

T = 3.21 + [(2 x 0.01) - (-1 x 0.01)] = 3.24

T0 : 3.21

t1 : +2

t2 : -1
Select the proper pinion height adjusting washer. Refer to "PINION HEIGHT ADJUSTING WASHER ". If impossible find the desired thickness of washer, use washer with thickness closest to the calculated value.
Example:

Calculated value... T = 3.22 mm

Used washer... T = 3.21 mm
