1 WHEEL UNIT SETUP AND ADJUSTMENT
1.1 UNPACKING THE WHEEL UNIT
Before unpacking and setting up your driving system, prepare a clean area with adequate
room for laying out the components. Review the list of wheel unit parts [Figures 1a & 1b] and
verify that everything is present to complete assembly.
ECCI recommends keeping the original box and packing materials in case the unit needs to
be shipped in the future. If shipping is needed, the unit MUST be shipped partially
disassembled as originally received, or damage will result.
1.2 WHEEL MOUNTING BRACKET
Before starting, examine Figure 2 for how the wheel unit should appear when assembled. Lay
out the components in a sufficient well-lit workspace.
1 Set the main steering chassis on a table upside down on a terry cloth towel or other soft
non-abrasive cushioning material to avoid scratching the cover. If your unit has a Lexan
cover, keep the protective covering on until all assembly is finished.
2 Using a 3/16 inch hex wrench, loosen the two center-most chassis tube bolts [Figure 3].
Do not remove them; back them out until the nuts between the bolt tubes and the gray
central structural plate can be removed and discarded. Then re-install the two bolts about
one turn and leave them loose.
3 Invert the table bracket assembly towards the central chassis structural plate and align
the two central slots with the previously loosened chassis-tube bolts [Figure 3]. The table
bracket should be seated between the spacer tubes and the main chassis structural plate.
4 Using a 1/8 inch hex wrench, attach the mounting bracket with the 3 supplied bracket
mount screws and nuts [Figure 3]. After tightening these screws, turn the two center-most
chassis bolts until tight, fully securing the mounting bracket to the main chassis plate.
5 Turn the unit upright and secure to a tabletop edge using the clamp of the mounting
bracket [Figure 4]. Note that it is possible to adjust the angle of the unit by adjusting the
height of the rear wheel mounting bracket. Rotate the bracket tensioning bolt [Figure 2]
until it is perpendicular to the underside of your mounting surface. Turn until it contacts
the underside of the surface. Do not over tighten. Turn till finger-tight and then using a
wrench, turn one-half turn more. Then lock the bracket by tightening the pivot set screw.
1.3 STEERING WHEEL ASSEMBLY
1 With the wheel unit upright and secured to the tabletop the steering wheel and shift
paddles can be mounted. Prior to assembly inspect the shift paddle set [Figure 5b]. Note
the importance of the two wire management slots at the back side of the paddles. These
slots accommodate the button wiring when the paddle/wheel assembly is tightened down
to the steering unit hub. It is critical that the wires pass through these slots and avoid
getting pinched during assembly.
(For Momo Corse wheel skip to step 5): Remove the wheel attachment screws from the
paddle set. Discard the small nuts that held them at the back of the assembly. From front to
back, the screws will pass through the steering wheel, optional wheel spacer (if supplied), the
shift paddle assembly, and into the threaded holes in the hub. Begin
