Nautilus Overhead guard installation instructions
These instructions are meant to be used along with the Nautilus overhead guard parts manual pages
730003.
1. Remove the front cover, the battery, the seat mount, and the right front corner roller.
2. On the right front frame lift the front edge of step pad 730967 to expose the right front
overhead guard mounting hole (on the frame approximately 9” to the rear of the front roller
attachment hole). Remove and discard the console mounting bolt and nut that are located
closest to it (the second bolt from the front).
NOTE:
The following procedure involves passing the fastening nuts and the driving socket into a tube
structure on the console. If either is allowed to drop into the tube it would be extremely difficult
to retrieve them.
3. Install the overhead guard bracket 730697 inserting the two mounting bolts through the bracket
and into the back side of the vertical frame tube. The nuts must be inserted through holes in the
front side of the frame tube. Leave these fasteners slightly loose for now.
4. Use a drift pin or punch to center the top hole in bracket 730697 with the mating hole in the
console then, while holding the top of the bracket up against the console, tighten the two
fasteners.
5. Install the left overhead guard frame 731020 leaving the fasteners slightly loose. Note: The
engine cover will contact the left overhead guard frame when raised.
6. Place spacer 731026 over the right front mounting hole (trim the length of the step pad as
necessary to clear the spacer).
7. Install the right side overhead guard frame 731012 leaving the fasteners slightly loose. It will be
necessary to tape the right front mounting nut to a box-end wrench to reach the mounting
location inside the frame tube.
8. Position the top plate 731024 in place on the tabs of the overhead guard frames by first hooking
the rear channel of the top plate around the rear tabs.
9. Install all ten of the fasteners into the top plate and through the tabs then tighten the fasteners
starting from the rear fasteners and working toward the front. Tightening in this fashion will
insure that the top panel lays flat.
10. Tighten the four overhead guard mounting fasteners.
11. Install edging 731027 on the back edge of the top plate
12. Install the two tube plugs 731028 in the openings on the top back of the overhead guard.
