Fig. P.13 The steering-rack oil nipples which must receive attention
WATER PUMP
Give the nipple on the water pump body one stroke only with the gun filled with S.A.E. 140 oil. The
oiling of the pump must be done very sparingly, otherwise oil will flow past the bearings onto the face
of the carbon sealing ring and impair its efficiency.
