When fitting the cap (2, Fig. 36) of the inertia pinion type starter, care should be take n
to ensure that the armature shaft is seated corr ectly in the housing and that the car-
bon brushes are in close contact with the commutator . Fit compensating washers and
fuse and screw on cap (3, Fig. 36).
The
carbon brushes should at all events be renewed when the engine is give n a
general overhaul.
Commutator
The commutator should have an even , grey -black surface , and must be fr ee of dust,
oil
and grease. Soiled commutators should be cleaned with a clean gasoline-damped
rag (not with waste wool) and well dried. Commutators which have b ecome sco red
and eccentri c must be re-turned in a suitably equipped works hop . By no means sho uld
a
commutator be worked on with sandpa per or a file.
Lubrication
Both bearings of the starter are p rovided with a· self-lubr icating bearing (Campo-
bush). These b earings must not be greased or tre a ted with gr ease-dissolving cleaners .
To
increase their service life, th e pinion and the gear rim should be cleaned per i od i-
cally with a brush dipped in gasoline and then re-greased (graphite grease, e. g.
BOSCH-grease Ft 1 v 13). If necessary, remove burrs from gear rim and pinion.
