Introduction
LifeTrac wheel couplers suffered catastrophic failure when used with tracks.
.
The key on the motor shaft sheared. We put on thicker couplers, and LifeTrac currently works - but we will not take it through destructive testing prior to testing splined motors.
.
It is suspected that the 4-wheel drive, when coupled by wheel tracks, makes the motors fight each other.
The new splined motors are these from Surpluscenter:
Removing Tracks, Adding Quick Connect Wheels
To remedy the failing coupler, we will remove the tracks as the first step, and run the motors in series to simplify control valve requirements.
