advisable, as the new insert would be “ proud ” of the remainder and take all the drive on the plate in which it had been fitted. It is advisable, if possible, to replace plates with either new or reconditioned ones. If all the new inserts are fitted to a plate, ensure that the inserts are level and flat and all contact the steel plates, taking their share of the drive. Examine the drive on the plates for wear. The plates with the inserts, drive on the outside diameter, and the plain steel, on the inside. The splines on the body and the plain steel plates driven by the body rarely show any sign of wear. The tongues on the plates with inserts, driving the sprocket, may show signs of wear and they may have “ cut ” in to the driven part of the sprocket. This wear obstructs the free movement of the plates when the clutch is operated. This can be rectified by filing or grinding the tongues on the plates square. Also the edge of the driven part of the sprocket. The only effect this will have on the clutch is a slight amount of "back-lash” when the clutch is engaged or disengaged. Examine plain steel plates for any rough­ ness. The back plate sometimes develops this fault. * Examine the roller race, rollers and the - cage.

Remove the cover plate, and the clutch shock absorber rubbers. (Fig. 12) A large “ C ” spanner is needed to remove the rubbers. This is placed over the body and engaged in the splines, and the large rubbers compressed while the small ones are removed. The handle of the spanner should be of such a length that the load can be taken by the users thigh, allowing both hands to be free to remove the rubbers. A substitute for a “ C ” spanner can be made by fixing a handle to an old plain steel clutch plate. Compress large rubbers and remove the small. A small, sharp-pointed tool is necessary lo remove the rubbers, as after use they adhere to the body. Large rubbers are easily removed, after the small have been withdrawn. Remove body from axle and replace in the reverse position. Remove the three stud nuts on the back cover plate. Back plate, roller race, back cover and body can be separated. 44. EXAMINATION OF CLUTCH PARTS. Examine clutch inserts. They should be “ proud ” of the plate. Fitting of separate inserts to a plate is not
