Identifying the Carrier Class & Pinion Mounting Dimension
Note the carrier class stamped on the carrier housing (See table
b
elow). This may be stamped on the carrier outer casing (Fig 2.4)
or the carrier mounting face. The following table contains the
cross reference detail for carrier class code to the mounting
pinion dimension D (eg. 283.5mm)
NOTE: Dimension D is essential to calculate the new shim pack
requirements when the original ring gear and shim pack are not
available.
Shim Pack Calculation
Calculate the shims required using the appropriate procedure 1, 2
or 3 below.
1. Calculating the Pinion Shim Pack Value - Original Ring Gear,
Pinion & Shim Pack with NOT AVAILABLE REFERENCE NO.
1.1 The standard theoretical pinion mounting dimension F is
235mm
1.2 Note the Pinion Cone (P.C.) value H marked on the drive
ring gear (Fig. 2.6). This can be either a + value or - value,
(e.g. + 0.10mm)

Fig. 2.5
F
1.3 Using the values identified for E, D, F & H above, calculate the
shim pack requirements using the formula provided below.
Formula: D - (F +/- H) - E = Shim Pack Value - see Fig. 2.6a
e.g. 283.50 - (235 + 0.1) - 47.63 = 0.77mm
NOTE: Use a shim pack as close as possible to the calculation
value obtained. Shims are available in thicknesses of 0.10, 0.15,
0.20 & 0.50mm.
