Tripper Arm Assembly

99F Tripper Arm and Gear for Autotrol 440 and 440i Timer Assemblies.

NOTE: The very old version ( 86F ) of this gear had the time of day stamped on the actual Gear.
The newer version we offer here is the only type now available and will work as a replacement.
If your timer is so old, as to have the old 86F gear, you might be wise to replace the entire timer with the new 460TC version, since other gear or timer problems are likely to occur due to the extreme age of the parts.
