DISASSEMBLY REMOVAL
1.Starter
1.1Testing before disassembly removal
(1)Clearance between pinion and housing
(pinion clearance)
(a)Connect the starter to a 12 volt battery
as shown in the illustration to cause the
pinion to shift into cranking position and
remain there.
Due to the amount of current being passed
through the solenoid series winding, this test
must be made within 10 seconds.
(b)Push the pinion toward the commutator
end by hand to measure its free movement
(pinion clearance).
(c)The pinion clearance must be 0.020 to
0.079 in. (0.5 to 2.0mm). If the clearance
is out of this range, make an adjustment
to it by adding or removing the packings
on the magnetic switch. Adding the
packings will decrease the clearance.
(2)No-load characteristics
(a)Connect the starter to a 12 volt battery
with an ammeter capable of indicating
several hundred amperes as shown in the
illustration.
(b)Close the switch to make sure the pinion
shifts into cranking position properly
and the starter runs at speeds higher than
is specified. If the current draw and / or
operating speed is out of the standard,
disassemble the starter for inspection
and repairs.
a)The size of wires used for this test must
be as large as possible. Tighten the
terminals securely.
b)This starter has a reduction gear.
Do not confuse gear noise with some
abnormal noise else.
c)When measuring the starter speed at the
end of the pinion, be ready for accidental
shifting of the pinion.
