Preload, or the spring tension necessary to fully retract the cord, can be achieved in either of two ways. Without the cord handle attached: 1. Secure one end of the cord to the sheave. Some manufacturers provide an anchor, others rely upon a nonslip knot. 2. Wind the cord completely over the sheave so that [...]
The replacement starter cord, or rope, should have the same diameter, length, and weave as the original and it should be made of unalloyed nylon. If the length is unknown, secure the cord to the sheave and wind until the spring coil binds. Allow the sheave to unwind for one or two turns and cut [...]
Replace the spring if broken, distorted, or too weak to retract the cord. Otherwise, leave it undisturbed. Replacement springs usually are prewound. Some come housed in a retainer and install as an assembly. Others are secured by a wire clip, reminiscent of the loading clips used on the old M-1 rifle. Align the outboard spring [...]
The sheave, also known as pulley or rotor, is secured by a central screw or by tabs around its rim. Once the hold-downs are removed, the sheave lifts off to expose the main spring. The trick is to lift the sheave without dislodging the spring from its housing. Should this happen, the unconfined spring lashes [...]
Before dismantling a starter, the main spring must be allowed to uncoil as much as the housing permits. It will still contain energy. Disarming is accomplished either by detaching the cord handle or by partially disengaging the rope from the sheave. The handle can be removed by untying the knot or by cutting the cord. [...]
