1.
Remove lock-up cover.
2.
Fasten the clevis (R-18107) to the threaded Lockup Rod (R-18108) with the short-threaded
end using a 3/8” hex nut to secure the clevis.
3.
Remove the cotter pin on the clevis and clevis pin and fasten the handle (R-18106) to the
clevis using the clevis pin and cotter pin that were just removed as shown.
4.
Insert the Lockup Rod that is attached to the handle into the spring plate and fasten the
handle to the rod support (R-18109) using one ½” x 3-1/2” bolt, two ½” washers, and a
½” nylock nut as shown.
Do not over tighten the nylock nut or the handle will be hard to move or may not move
at all. Handle will need to be removed for bending and/or trimming for desired location.
5.
Adjust the rod support up or down by loosening the bolts and nuts that hold the rod sup-
port so that the handle is parallel with the ground and tighten the ½” bolts and nylock
nuts that hold the rod support.
6.
Place one 3/8” washer and nylock nut on the end of the lockup rod as shown. Use a 5/16
wrench to keep the lockup rod from turning when fastening the nylock nut.
7.
Move the handle to the desired location making sure nothing will be in the way when
engaging the lockup and tighten the nylock nut so the 3/8” washer is against the spring
plate.
8.
Test the lockup to ensure proper functionality.
9.
Bend and/or trim the handle to desired location.
