Abstract:
A friction starter drive unit comprises a drive pinion for meshing with a starter ring gear. A drive element and a friction clutch are between the drive element and the drive pinion. The friction clutch has a reaction element rotatably fixed to the drive pinion and a pressure element solidly connected to the drive element. The drive element moves relative to the reaction element between uncoupled and coupled positions, and a resilient means biases the reaction element and the drive element toward the uncoupled position. A retaining washer is rotatably fixed to the reaction plate or the drive element. When the retaining washer is rotatably linked to the reaction plate, the resilient means is positioned between the reaction plate and the retaining washer, and, when the retaining washer is rotatably linked to the drive element, the resilient means is positioned between the drive element and the retaining washer.
