NOTE

Bevel pinion spigot end number can be in 1,000ths of an inch or 100ths of a millimeter.

Millimeters will be indicated with a decimal point. Example: +3 = 0.003 in., +0.03 =

0.03 mm. Be sure to convert millimeters to inches by multiplying by 0.039 before

performing the following calculations:

(c)

If old bevel pinion cone number is a plus (+) value, subtract number from shim pack (34)

thickness measured in Step (a). If old bevel pinion cone number is a minus () value, add

number from spigot end of old bevel pinion (29) to shim pack thickness. This is the thickness

of standard shim pack, without a cone variation.

(d)

Read number on spigot end of new bevel pinion (29). Record number.

(e)

If number on spigot end of new bevel pinion is a plus (+), add number to standard shim

pack (34) thickness calculated in Step (c). If new pinion cone number is a minus (), subtract

new pinion cone number from standard shim pack thickness calculated in Step (c). This is the

thickness of new shim pack with cone variation.
