6. Reinstall the brake shaft with the roll pins.

Note: The roll pins must be a press fit.  If they are loose, they must be replaced.

NOTE: when installing the brake shaft on models with the three piece shaft, ensure that the brake shaft tension spring is installed properly.  The spring often comes loose during repairs and must be re-inserted into the chassis.

Note: Ensure that the seat switch connector is not pinched by the seat frame or that the wires can not come in contact with moving parts of the transaxle.
