Reinstall belt cover by placing the cover in
position. While maintaining a slight gap between
the cover seal and the side plate, install each
mounting bolt until the threads engage in the
insert. The gap will allow visual alignment of the
bolt to the threaded insert. After all bolts are
installed, tighten until the stand offs inside the
cover contact the side plate. Do not overtighten.
