Sega ENDURO RACER
Steering Modification

Sega ENDURO RACER has been an excellent
earning garre for our conpany, but due to
the nature of the garre play, we have been
plagued with repeated failures in the
steering asserrbly.
THE PROBLEM
The problem exists in the type of bearings
used to hold the handlebar main shaft. My
wear or play in either of the two bearings
causes the steering potentiometer gear to
pull away from the main shaft gear during
a hard "wheelie." This has caused
calibration problems and, on occasion, has
led to pot breakage.
THE SOLUI'ION
The following rrodification allows the
bracket which holds the pot to float, and
the two gears are held together with
spring pressure. Previous to this
rrodification, our garre was losing steering
2 - 3 times per week. As of this writing,
I have not received a single complaint
regarding steering problems (4 weeks).

5. Install the rrodified bracket using (2) a
10-24 x 1/2" machine screws and (2) 10-24 •
lock nuts. Tighten these screws only
enough to prevent up/down play while still
allowing free side-to-side rrovement of the
bracket.
6. Slide the bracket up and re-install the
pot and steering gear.
7. Loosen the metric bolt which secures
the handlebar shaft bearing. Install under
this bolt a keyhook or similar device from
which the other end of the spring will be
attached. Tighten the bearing bolt.
8. Using a spring that will apply 3-4
pounds of pressure against the steering
gear, attach it to the keyhook and the
small hole you drilled in the pot bracket.
9. Lubricate around both sides of the pot
bracket to assure smooth motion.
10. To calibrate the pot is now simply a
matter of pulling back on the pot bracket
and rotating the gear to its proper
A
position.

If you have any questions or need any
assistance, feel free to call me at (215)
572-6966.
THE K:DIFICATION
1. Rerrove the pot bracket from the
steering asserrbly and renove the gear and
pot from the bracket.

If 1£/Y
2. Viewing the drawing, extend the slot in
the bracket all the way to the edge of the
bracket using a hack saw or similar
cutting tool. This will allow easy access
to the steering pot should it ever need to
be serviced. File any burrs or ragged
edges to prevent any binding.
3. Drill a small hole in the side of the
bracket to accept one end of the new
spring.
4. Widen the bracket rrounting holes in the
steering asserrbly using a 5/32" drill.
