INSTALLATION
1. Place shift shaft in ``Neutral,'' then align flats of shift shaft with switch.
2. When installing an old switch, proceed as follows:
a. Assemble mounting bolts-to-case, loosely, then insert a 3/32 inch maximum diameter gauge pin in service adjustment hole.
b. Rotate switch until pin drops in to a depth of 1/8 inch.
c. Install retaining bolts and nut, then connect electrical connector.
3. When installing new switch proceed as follows:
a. Install mounting bolts and tighten. If bolt holes do not align with mounting boss on transaxle, ensure shift shaft is in ``Neutral.'' Do not rotate switch. Switch is pinned in ``Neutral'' position.

a. Place transaxle control shifter assembly in the ``Neutral'' notch in the detent plate.
b. Loosen switch attaching screws and nut.
