Replacing the Hydrostat-Drive Belt
1. Insert a nut driver or small piece of tubing onto the
end of the belt-tensioning spring.

heavy load, and releasing the tension of the
spring improperly may cause injury.
Use care when de-tensioning the spring and
replacing the belt.
2. Push down and forward on the spring end to unhook
it from the bracket and release tension on the spring
(Figure 57).
