IN nearly every case where such slipping is experienced it is due to an overplus of thick oil finding its way on to the clutch faces. The remedy for this state of affairs Is j to clean the excess oil away. ! This can be done by means of thoroughly swilling the clutch out with j petrol. It is advisable to use kerosene for the first flushing as this seems to get deeper into the plates and allows the petrol to make a cleaner job. In most cars there is an inspeotlon plate in the top of the clutch housing, and this will have to be removed. "While an assistant pushes the clutch out as far as It will go, about a cupful of kerosene should be squirted, by means of a long-necked oilcan, between the plates. The clutch can then be let in and the engine started. With the clutch running at a medium speed, the centifrugal force will throw the kerosene off the plates, carrying a

large percentage of the excess oil with it. ■ • The same process can then be repeated two or three times with the petrol, using about a cupful each time.With a dry plate clutch no further work will be needed, but in the case of the metal to metal unit a small amount of light oil, such as "3 in 1," should be injected between the plates. .. ' ; After the clutch has been cleaned „' in this manner it will quite often be .' found that slipping still occurs. This is due to an entirely different cause. The clutch plates being clean they require the rearward travel of the clutch pedal to be greater before they are brought into close contact. The clutch pedal will either be found to come back against the footboards or the stop set screw which is fitted to some clutch pedals will be found screwed down too far. Slightly lifting the floor board by means of a rubber or fibre pad, or easing the set screw until the clutch is fully engaged, will cure the slipping.
