Next, the Y-stop is installed on the longer, inboard shaft.
There are small splines on the door’s shaft that align
with groves in the bracket, sort of like a steering shaft. The
Y-stop is adjusted (repositioned) on the shaft so that the doors
open properly to their vertical position. The stops are bolts
that can be turned to allow more minute adjustments. When
it is installed correctly, an audible “click” will be heard when
the bracket rotates to the full-open position and activates
the headlamp position switch. The aluminum Y-stop is
comparatively brittle and it doesn’t require much torque
to tighten it.
16
Installation of the electric motors comes next. They are
specific to the left- and right-hand sides, denoted by “LH”
and “RH” designations in the part numbers cast into them. They
mount in a specific location and the rectangular slot seen here
aligns with the pivot shaft, which means the motor may have to
be hand-turned to get it into the proper position. Don’t forget the
nylon bushing in front of the slot, too.
17
Each motor installs easily from the
top of the body, sliding onto the
pivot shaft. Once seated, a short steel
bracket connects it to the header panel.
20
In the home stretch now, the
headlamp buckets are installed.
They simply screw into place via tabs on
the housings.
18
Here’s one of the installed motors.
Note the ground wire attached to the
attachment bracket (with a star washer for the
best connectivity), which holds the motor to
the header panel. The rest of the wiring has
also been connected at this point. Note, too, the
retaining clip attached to alignment pin on the
bearing socket. The pin helps position the motor
correctly and the clip is installed afterward.
21
One thing about the buckets: Their
respective harnesses don’t fit
through the round openings in the sides
of the housings, so their terminals must
be removed from the connectors to allow
the wires to be fed through the hollow
outer pivot shafts.
19
With both motors installed,
the battery is connected
and the headlamp door-opening
switch is turned on to check
the rotational operation. They
worked on the first try, here.
Their vertical positions are
critical, too, for ensuring proper
headlamp aiming.
22
After fishing the wires through
the opening in the housing
and reconnecting them in the proper
positions within the connector, they’re
simply plugged into the rest of the wiring.
