Seven Day Skipper Wheel used on Autotrol 440 and 440i Timers instead of the standard 6 Day Skipper Wheel.
What is involved in changing the 440i 6pin 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 list here.
The NEWER - 440iHV "revised" version ( after January 2008 ) require special 7 day wheel and special 7 day skipper arm gear ( neither of these are listed on our website - yet ).
