Seven Day Skipper Wheel ( 14F-7 or 1031742 ) used on Autotrol 440 and 440i Timers instead of the standard 6 Day Skipper Wheel.
What is involved in changing the 440i 6 pin skipper wheel to a 7 day wheel?
* 440i ( all 12 volt models, and any 120 volt model pre- 2008 ) only need the 7 day skipper wheel listed here.
The NEWER - 440iHV "revised" version ( after January 2008 ) require special 7 day wheel (3007523) and matching special 7 day skipper arm gear (3007520) .

Note: Most 440 and 440i use the 6 day skipper wheel, but this 7 day wheel is an option some people have or would like to have on their timers.
