Alfa gtv fitting 147 steering wheel
Well sick of the site of stock gtv steering wheel and from looking at previous threads re fitting got somewhat confused. Basically its not a simple job to fit the 147 steering wheel to a gtv because neither the P1 or P2 spline the correct pitch for the 147 wheel, even though the diameter is close. The spline boss stubb on a 147 is also larger in diameter and shorter than the gtv wheel so the normal practice would be to use the 147 clock spring but still a pain as the connectors need rewiring which i worked out but still not prepared to hammer on the steering wheel to fit the spline.....
so to avoid all that hastle got an old gtv wheel and completely removed the boss. Then
machine the boss thickness so that it would sit almost flush with 147 wheel boss.
to keep integrity and strength i machined out the sline boss of the 147 wheel and machined
a rebate in old boss so that the old boss would sit centrally in the 147 so no issues with
an ofset wheel etc... The two boss plates are then bonded and 4 machine screws used to
complete the fit. In fact its probably stronger than the original boss and still retains its integrity...job done. I havent on this occasion used the airbag as its nearly ten years and probably coming to the end of its manufacturers life expectancy. If you do need to retain
the airbag then no problem just need to fit older style airbag connector to 147 airbag unit
and it will only work on the later trw ecu units. If no airbag required then terminate with a
3ohm resistor and make sure its fitted before reconnecting the battery or a fault light will occur. If not wanting to so this yourself then would be pepared to offer this as a service if required or offer more information.... See pics to see what a diff....
