| -17- Rear Shock Dampers. LOP. F.{Mr Friese} 87771. The poundage was suspected of being low at first, but removal shewed them to have an initial poundage of 70-75 lbs. The damper unit pump poundage was found to be low, and when this was corrected the rear dampers behaved in a normal manner, whereas before they allowed the car to pitch up and down on undulating surfaces. There has been little loss of oil, the total amount added being O.S.R. 51 c.c. and N.S.R. 73 c.c. We have noticed no knocks or looseness from the damper connections. There has, however, been a slight leak from the glands, but no more than on previous cars. Both dampers, instantly responded to the control. Petrol Tank. LOP.F. 88035. 33-Gallon Tank. Lec.4647/4715/4794 The petrol tank has been satisfactory, giving us a range of 300 miles of fast driving. We were not able to hear any undue drumming when the tank was nearly empty as has been noticed previously. There was a bad smell of petrol in the rear of the car during the former part of the mileage especially after the tank had just been filled. This was traced to the vent, we therefore fitted a pipe in place of this leading to the rear of the frame, since when we have had no more trouble from that source. Petrol filter fitted to rear of cross member. The filter in this position has not given any trouble, and we find it easy to remove for cleaning. It has not been affected by heat from the silencer. Electrical Equipment. Battery Box & Fittings. The box remained firm, no trouble experienced with the anchorage. The box is very apt to fill up with mud and gravel thrown up by the wheels. Battery. The current supply was adequate for all the demands made. No appreciable water evaporation took place The total amount added was 80 c.c. | ||
