Installing MyChron 3 on the steering wheel
Most of steering wheels have existing holes in the three central arms that will
accommodate the MyChron 3 display unit. If the steering wheel arms are solid,
mark the point where the hole is to be drilled and then indent a drill reference
point with a large nail or hole punch, to minimize drill wander. It is recommended
that an 8 to 10 mm drill bit be used. Do not over-tighten the 8 mm nut. Over-
tightening the nut may cause damage to the display unit casing.
As showed in the previous drawing, we suggest using the plastic washers
furnished as equipment to keep your MyChron 3 separate from the steering
wheel, in order to avoid possible damage to the display unit.
