STEERING JOGGLES. The cross-steering tube load was 4 1/4 lbs, made 11 1/4 lbs. The track of front wheel was parallel made .125 toe in. The ball contacts in the cross steering tube, full movement of adjustment could not be obtained due to the binding of the bolt in the groove. STARTER MOTOR SLIPPING. The starter motor slips considerably with the engine dead cold. We found the tabs of the cage pressing were too broad for the serrated friction washers which made them bind. This does not allow the proper amount of friction to take place on the cork washers. There was a faulty cork washer fitted, a portion having broken away. The spring loading is too light for the higher compression ratio. TALKGAGE FAILURE. We found that failure due to the face connection on the petrol tank leaking. The drilling and screwing of the holes for holding the unit had left small burrs which had to be removed. No other faults were found to cause a failure. REAR LUGGAGE CARRIER. The curved tube rail of the luggage grid fouled the spare wheel carrier tube and caused a rattle. The setting of this tube is too close. CENTRAL LUBRICATION. The Bijur pipe coil attached to the N.S. rear spring broke during the run to Chateauroux. It appears to be coiled in the wrong direction for the correct working of the coil, also the aluminium housing requires the sharp corner clearing away at the point where the pipe leads out. INJECTION PIPE. There was an air leak at the front joints. This was caused by the spigot holes not being sufficiently deep, making the pipe ride on the spigots. | ||
