S2 Removable Steering Install
Eliseparts steering adaptor and snap-off boss kit installation instructions for a 2003 S2 Elise
1. Straighten steering wheel and try and chock the front wheels to avoid movement.
2. Remove the steering wheel centre pad (simply pulls off) and disconnect horn spade connectors
3. Push back (using a flat blade screwdriver) the locking tabs on the steering column 22mm nut.
4. Put a dot of tipex or the like on the inside top of the splined shaft incase you knock or turn it with the wheel off and lose TDC
5. Undo the 22mm nut (may need deep reach socket) but leave on the last 3 threads of the steering column.
6. Using a 2 prong puller slide thin jaws in to the oval holes on the back face of the wheel sideways on then rotate them to face inwards, connect to the puller body and pop the wheel off the splined shaft.
7. Unscrew the 22mm nut don’t let the spring or lock plate sproing off into hyperspace and careful not to rotate the shaft and loose straight ahead.
8. Once the steering wheel is removed from the splined shaft turn it over and pop off the horn contact plate / slip ring.
9. You will see 4 x M6 Allen headed bolts holding the centre hub to the Lotus steering wheel, remove these 4 bolts and the steering wheel detaches.
10. Attach the 20mm Eliseparts ("EP") adaptor to the centre hub using the 4 x M6 Allen headed bolts you removed, pop the horn slip ring back on and feed the wire back through if you need to.
10A. If you have a boss kit where the black negative contact is isolated you may need to make up a wire with a spade crimp on one end and a ring crimp the other and file down to sit under one of he the M4 bolts and run the wire up through one of the oval holes on the back plate.
11. Play around with the EP adaptor -> snapoff back plate -> snapoff main body orientation to make sure the holes align as the EP adaptor has several offsets to choose from.
12. Slide the joined EP adaptor and centre hub onto the splined shaft then put the metal lock plate and 22mm nut and tighten to 20lbft (may need a rubber band wrench to hold the column still).
13. Connect the positive wire from the slip ring to the positive on the snap off back plate. Double check negative is earthing - the wire on some kits is isolated and there is no where to attach the connector as in step 10A. As a temporary fix you could just jam the spade between between the mating faces of the eliseparts adaptor and the snapoff back plate but this is NOT RECOMMENDED.
14. Bolt the snap off backing plate to the eliseparts adaptor using 6 countersunk M6 allen screws.
15. Bolt the thin lipped adaptor to the main snap off body using 6 countersunk M6 allen screws lip out to locate the steering wheel.
16. Attach the main body and lipped adaptor to the steering wheel using M5 countersunk allen screws.
17. Connect the horn wiring leads and pop the horn button in (You will not need the silver lipped momo horn adaptor plate).
18. The steering wheel now snaps on to the adaptor.
