Owners manual

General Installation Notes:
Please read these instructions completely before beginning
the installation. If you have any questions please call.
Before beginning the installation, disconnect the negative
battery cable and use wheel chocks to block the vehicle's
wheels.
Make sure the engine, transmission, body and frame are
properly grounded. We recommend using anti-seize lubricant
on all aluminum threads.
IMPORTANT: The Clayton Machine Works (CMW) Throttle
Pedal is designed for use with a Lokar Throttle Cable. Most
stock style cables will not work.
If your vehicle has an automatic transmission, installation of a
Lokar Kickdown Kit (if applicable) is strongly recommended.
Refer to Fig. 1 for the component names.
Step 1: Remove any existing throttle pedal assembly and
linkage components.
Step 2: Disassemble the CMW Throttle Pedal by removing
the 1/4"-20 x 1/2" flat head bolt from the end of the
mounting shaft and sliding the lower and upper arm
assemblies off of the mounting shaft.
Step 3: Install the throttle pedal mount onto the firewall.
MB1 style mounts are installed from the engine
compartment side using the stock hole where the
original throttle linkage was mounted. Fig. 2 MB2
and MB3 mounts are installed on the passenger
compartment side of the firewall. Use your original
bolts or studs and nuts to attach the throttle pedal
mount to the firewall. If your original hardware is
missing or damaged, MB1 and MB3 will use 1/4"
diameter nuts and bolts of the appropriate length
(not supplied). MB2 mounts are threaded for 1/4"-20
bolts (not supplied).
The MB3 throttle pedal mount (1968-72 GM A-Body)
can be rotated 180 degrees and installed with the
pivot shaft and pedal arms on the left side of the
mount if needed for clearance at the transmission
tunnel. Fig. 3
Step 4: Reassemble the CMW Throttle Pedal with the lower
pedal arm assembly pointing down and the upper
pedal arm assembly pointing up.
Step 5: Push the top of the upper arm assembly forward so that
it is parallel to the firewall. Mark the firewall in line with
the 3/16" hole on the end of the upper arm assembly.
Drill a 5/16" diameter hole through the firewall for the
Lokar Throttle Cable fitting to mount into.

Step 6: Install the Lokar Throttle Cable according to the
instructions supplied with the Throttle Cable. You
may have to reposition the upper arm assembly on
the Throttle Pedal in order to get the Throttle Cable
adjusted correctly. Make sure there is no binding in
the throttle linkage and that the throttle returns to the
closed position when it is released.
See Fig. 4, 5, and 6 for a fully assembled Throttle Pedal.
NOTE: Once the Throttle Cable is installed, make sure
that the Throttle Pedal is completely floored when
the throttle is wide open. If the Throttle Pedal is not
completely floored at wide open throttle, you will need
to either change the position of the lower arm assembly
on the Throttle Pedal or install a pedal stop.
