steering wheel adjustment ACURA NSX 1991 Service Repair Manual

Installation

NOTE: Before installing the steering wheel, make sure

the front wheels are straight ahead.

CAUTION:

• Be sure to install the harness wires so that they are

not pinched or interfering with other car parts.

• Do not replace the original steering wheel with any

other design, since it will make it impossible to prop-

erly install the airbag. (Use only genuine Honda

replacement parts.)

• After reassembly, confirm that the wheels are still

straight ahead and that steering wheel spoke angle

is correct. If minor spoke angle adjustment is neces-

sary, adjust the tie-rods only. Do not remove and

reposition the steering wheel.

Confirm that the airbag assembly is securely

attached to the steering wheel; otherwise, severe per-

sonal injury could result during later airbag deploy-

ment.

1. Before installing the steering wheel, center the

cable reel.

Do this by first rotating the cable reel clockwise

until it stops.

Then rotate it counterclockwise (approximately two

turns) until:

— The yellow gear tooth lines up with the mark on

the cover.

— The arrow on the cable reel label points straight

up.

If an intact airbag assembly has been removed from a scrapped car or has been found defective or damaged during
transit, storage or service, it should be deployed (see section 23).
Before removing the gearbox, remove the ignition key to lock the steering shaft.
After installing the gearbox, check the wheel alignment and adjust if necessary.ProCarManuals.com

Wheel Alignment
Front Wheel Alignment Adjustment Procedure (cont'd)

NOTE:
NSX four wheel alignment requires the use of equip-
ment designed specifically for four wheel indepen-
dent suspensions and capable of immediate

feedback.
The ride height is very important for setting the align-
ment. For every 10 mm of change in the front ride
height, the camber will change approximately 10

minutes.
The front alignment settings on the NSX are

interactive.
A slight change in toe will dramatically change the
camber.
1. Drive the car on the alignment rack.
2. Check the tire pressure and ride height as described on page 18 - 6.
3. Center the steering wheel.

Toe
1. Measure the length of the threaded section on
the right and left rack ends.
Standard: 11 mm for shoulderDifference between right and left: 1 mm max. 2. If the measurement is out of the specification,
loosen the locknut and adjust properly.
