| Contd. Clutch. The springs in the clutch are too weak to hold the full torque on top gear. The clutch is very free. We have had trouble with the clutch trunnion thrust race. Gear Box. The gears appear very good for silence - the box is also good for oil-retaining. Hs.{Lord Ernest Hives - Chair} | ||
