'SS{S. Smith}' CLUTCH. X7300

On dismantling the 'SS{S. Smith}' clutch, we find that an excessive quantity of oil has got on the friction surfaces. As oil is almost invariably put in the clutch shaft when the car is stationary, it is not safe to rely entirely on centrifugal action to prevent oil getting to the ferodo. We therefore recommend that the lip is increased in size and that the number of drain holes is increased.
