SLIPPING CLUTCH

DANGER OF WEARING. A. considerable number of cars are in use in which the clutch runs in oil, automatically supplied from the engine; any excess of oil drains back into the sump. In such cases it is essential to have any tendency toward clutch slip immediately rectified. If the clutch is allowed to slip for any lengthy period of time the cork inserts gradually wear away, which results in fine cork dust mixing with the oil, a large proportion of which is carried through to the engine. It sometimes happens that a car is allowed to remain in service with a slipping clutch until the cork inserts are badly worn. In such a case, unless explicit instructions are given to the firm carrying out the repairs to remove the sump and thoroughly cleanse the bearing lubrication system of every trace of cork dust, serious trouble is likely to develop before longthrough the oilways and pipes becoming choked.

Even if the slipping has been rectified before the inserts were sufficiently worn as to necessitate renewing them, it is advisable to have both the sump and the clutch chamber drained, then swilling them out with a pint or

two of thin oil (not paraffin) before refilling with fresh oil of the recommended grade. These cork-insert clutches are capable of giving very long service if properly treated, and have the advantage of providing an extremely sweet pick-up. Slipping is only likely to occur if a' driver makes undue use of the clutch and neglects the adjustment thereof for long periods.
