! Stop engine, and let cool.
! Disconnect battery, negative
() cable first.
Remove right side engine panel.
1 Plug PLG39/Receptacle RC39
2 Throttle Solenoid TS1
3 Shoulder Bolt And Nut
4 Throttle Link
5 Throttle Solenoid Plunger Rod
6 Jam Nut
7 Throttle Arm
8 Throttle Arm Stop Screw
Disconnect solenoid plug PLG39
from wiring harness receptacle
RC39.
Remove shoulder bolt and nut from
throttle link.
Remove solenoid from mounting
bracket.
Note how much thread is visible on
solenoid plunger rod. Loosen jam nut
just enough so throttle link can be re-
moved from solenoid rod.
Install throttle link on new solenoid
plunger rod. Turn link until the same
amount of thread will be visible on
plunger rod when the jam nut is tight-
ened. (Do not tighten jam nut yet.)
Mount solenoid on bracket. Move so-
lenoid plunger manually to align slot
in throttle link with hole in throttle arm.
Insert shoulder bolt through slot/hole
and secure with nut.
. Be sure solenoid plunger rod
pulls all the way in “bottoms”
when energized. If plunger rod
does not pull all the way in, re-
adjust throttle link.
. Throttle arm should not contact
stop screw when solenoid is en-
ergized. If necessary, adjust
stop screw to create gap be-
tween throttle arm and stop
screw.
Tighten jam nut on solenoid plunger
rod. Verify all other hardware is tight.
Connect solenoid plug PLG39 to wir-
ing harness receptacle RC39.
Reconnect battery, negative () lead
last.
Check engine speeds and adjust if
necessary according to Section 8-8.
Reinstall side panel.
