Disassemble the Pinion Assembly

The pinion assembly consists of a brass pinion mount

(the outer sleeve), a steel pinion (the hollow inner shaft

with a gear on it), a slotted brass retaining ring

(opposite the gear end), and 60 steel bearing balls (30

of which support each end of the steel pinion). The

pinion assembly is disassembled by unscrewing the

retaining ring (which is staked in place with adhesive)

from the steel pinion, after first softening the adhesive

by thoroughly heating it with a heat gun (see

Figure 56 – Heat the slotted brass retaining ring

Note that once the retaining ring has been loosened,

the steel balls supporting the pinion ends will be free to

come out, and these will fall all over hell and gone

given half an opportunity. To prevent this, only remove

the retaining ring while holding the pinion assembly

over a catch tray of some sort to collect any steel balls

that are inadvertently dropped. A magnetic parts tray,

as shown later in this article, is ideal for this purpose,

since the magnet in the tray will attract the steel balls to

prevent them from bouncing or rolling out.

thoroughly heating the retaining-ring end of the pinion

assembly, use pliers with non-marring jaws to grip the

gear-end of the steel pinion (see

The key word here is "gone".

Figure 58 – Remove the slotted brass retaining ring

As the slotted brass retaining ring starts to loosen, do

not allow the gear-end of the steel pinion to slip out of

the brass pinion mount, otherwise the steel balls

supporting the gear-end may fall out through the

resulting opening and become forever lost. While being

careful to keep the gear-end of the steel pinion fully

seated within the brass pinion mount, remove the

slotted brass retaining ring from the opposite end.

Beneath the slotted brass retaining ring will be 30 steel

bearing balls.
