•1946 BUICK STARTER PINION ENGAGEMENT & DISENGAGEMENT CORRECTION: If starter drive clutch pinion does not engage flywheel (on starters
buUt before August 1, 1946) replace Shift Lever, Part No. 1884808, with redesigned part of same number which may be identified by zinc-plated finish
(original lever painted black) which will correct interference between shift
lever and collar.
NOTE—Starters on which this correction has been made may be identified by
spot of white paint on frame above name plate and by zinc-plated finish of
lever. Starters built after Aug. 1,1946 (Serials No. 6-H-l up) have this new lever.
If Starter does not engage or cranks continuously (with new type shift lever
described above)—Check for binding of solenoid contact disc and pushrod on
terminal plate guide pin. Replace contact disc and pushrod assembly if guide
hole in eccentric, straighten guide pin if it is bent.
DESCRIPTION:—Solenoid type combined starting switch and pinion shift (with
control relay in solenoid case) mounted on the starter field frame with the
solenoid plunger linked to the pinion shift lever.
OPERATION: When the pushbutton switch is closed, or accelerator pedal is
depressed (vacuum switch type), with the ignition turned on, the solenoid relay
circuit is completed, energizing the relay and closing the relay contacts. This
completes the solenoid circuit. The solenoid plunger is drawn into the coil,
meshing the starter pinion, and closing the starting switch contacts. When
the engine begins to fire, the solenoid relay circuit is broken in one or more
of the following ways:
(1) Operation of the vacuum switch. Caused by the vacuum built up in
the Intake manifold.
By the rise in generator voltage. Where solenoid relay is grounded
through generator main brushes or auxiliary contacts in cutout relay.
the voltage built up by the generator opposes the current flow
through the solenoid relay winding.
(3) By releasing the pushbutton switch or ignition key. On all car model
installations where solenoid relay is grounded directly to starter field
frame, the circuit will not be broken until the pushbutton Is released.
(4) Through Neutral Safety Switch (automatic transmission cars).
When the solenoid relay circuit is broken, the relay contacts open, breaking
the solenoid circuit. The starting pinion is demeshed by the shift return
spring and the starting switch contacts are opened by the contact spring.
PERFORMANCE: Solenoid Switch. Solenoid should close (bottom in coil) against
70 lb. pull with y2" gap drawing 65-71 amperes at 5 volts. While closed, current
should be 12-14 amperes (hold-in coU only).
SOLENOID RELAY SPECIFICATIONS
Solenoid 1542, 1545, 1546. 1547. 1548
Contacts Close—1.9 volts max.
Contacts Open—1.0-1.2 volts.
Contact Gap—.035".
Air Gap—.012" (contacts closed).
Solenoid 1118019, 1118021, 1118102, 1118141
Contacts Close—3.0 volts max.
Contacts Open—1.9 volts.
Contact Gap—.025".
Air Gap—.015" (contacts closed).
CHECKING & ADJUSTMENT: Check Solenoid and Relay performance (above).
Adjust solenoid plunger link for correct pinion clearance as follows:
Solenoid Setting—Clearance between end of pmion and inner face of starter
housing should be 3/16" (see Cadillac Note below) with the solenoid plunger
bottomed in core. Adjustment wUI be simplified if lead disconnected at terminal
on starter field frame (so starter wiU not spin) and relay contacts closed so
that plunger is drawn into coil core. Press back on pinion to take up backlash
in overrunning clutch, remove solenoid plunger link pin, adjust link (by turning link stud in plunger) until pin can just be inserted at forward end of shift
lever slot
CadUlac 1940-49 Note—On these starters, pinion travel (from disengaged or
at rest position to fully engaged position with solenoid plunger bottomed in
core) should be 23/32" to 25/32".
SERVICING: Pinion Assembly & Spring. Compression spring tension should be
at least 34 lbs. at 1". To remove spring, press shift collar down on pinion
sleeve to compress spring untU lock ring on end of sleeve is exposed, remove lock
ring. Spring and collar can be serviced but no attempt should be made to dismantle overrunning clutch mechanism. Clutch is packed with high melting
point grease and pinion assembly should not be cleaned by any method which
may remove this lubricant.
Shift Lever Return Spring—Return spring on shift lever should have tension
of 9-12 lbs. (start of travel), 28-35 lbs. (end of travel). Weak spring may cause
sluggish disengagement particularly in cold weather or if shaft is gummy.
