| BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Ws. X3806 DA{Bernard Day - Chassis Design}1/M18.5.28. CENTRALISED CHASSIS LUBRICATION. X.3806 X.7330 X.7150 Referring to the list attached to DA{Bernard Day - Chassis Design}3/M17.5.28., the following points require slight modification, but the work done does not seem enough to justify a drg., and we should be obliged if Derby would do what is required : Point (3) - HAND BRAKE EQUALISER. Shaft requires drilling at each bearing with horizontal holes so that it may fill approximately half-way. The hole for the star piece shaft bearing is approx. as shewn on N.Sch. 2456 but horizontal. The hole through the star piece shaft to feed to R.H. bevel bearing could be approx. 45° from bottom centre. Point (6) - FOOT BRAKE COUNTERSHAFT. Both ends of inner shaft plugged. Feeding in hole vertically under drip plug. Horizontal hole in each end bearing and also opposite centre of outer shaft. Point (9) - HAND BRAKE BEARING. The shaft might be partly filled with oil by a vertical hole in the top of the shaft in centre of annulus and two horizontal holes in shaft at end bearing. Point (19) - WATER PUMP. Would Derby please arrange a drip plug in the frame side channel near to the water pump, and lead a pipe to a ¼" banjo and set screw on the water pump bearing. This would reduce the hole in the pump bearing, but a larger banjo can be used for the first car. The drip plug in frame consists of a stud (or bolt) with cap nut, a double banjo in the trunk pipe, and a single banjo leading to the pump bearing. (SEE ORIGINAL FOR SKETCH). Point(14) - STARTER EPICYCLIC. & (31) - STARTER MOTOR. Very infrequent lubrication is needed, and it is proposed to return to the standard lubrication by an oil cup. It could be attended to when the clutch is lubricated, though probably much less frequent attention is necessary. contd :- | ||
