Objectives of this task:
To fit the panel mounted throttle linkage to the instrument panel housing.
Materials required:
Resin and flock
Card # J4 “
Panel Mount Throttle

Fit the cross shaft bearing blocks
The throttle cross shaft is used to determine the side-to-side position for the bottom half of
each bearing block, so the first task is to assemble the cross shaft as shown above.
Now, working from the rear of the panel, make a
mark 50mm in from the bottom of the rear lip on
each side (as shown at left) and position the bottom
half of each bearing block behind each mark. Sit the
assembled cross shaft in each bearing block and
move the bottom half of each bearing block out
until the cross shaft has no side-to-side movement.
Make sure that the cross shaft is evenly spaced in
from each side of the panel, then mark the position
of each bearing block and flock each block in place,
using the cross shaft to keep the blocks in
alignment. Leave overnight to cure.
Next day run a 3/16” drill through each hole in the bearing block and drill
through the panel housing, then grease the throttle cross shaft, put each bearing
block cap in place and fix it to the panel housing with 3/16” screws, bearing
plates (shown at right), washers and Nyloc nuts and tighten the nuts to safety.
Too much tension will make the throttle stiff to move, so test the amount of
friction as you tighten the nuts.
