NEW PHANTOMCodename for PHANTOM I COMPLAINTS. ---------------------- BRAKES. No. of. Servo Jaggers. 2. Cured same by very carefully rebedding the friction surfaces of the Servo motor under light pressure. Also increased the friction on the two Suspension links of the balancing levers. Friction overcome at 25 Lbs. pull. Servo Thuds. 1. Overcome by increasing the friction on the two suspension links of the balancing levers from 8 1/2 Lbs. initial pull to 25 Lbs. pull. Squeaking Brakes. Front. 7. Cured by dismantling front drums and easing the leading edges of front brake shoes. also We always lightly rough up the ferodo surfaces. Slackness in Front Ropes. 2. Overcome by adjusting the jaw on the pull rod (forward motion) which is attached to the G.72511a Hub with balancing levers. Springs not comfortable.Rear. 3. In two cases we had to fit rear springs 200 Lbs lighter, made tyre pressures O.K. & checked shock absorber adjustement. The last case, overcome complaint by fitting rear springs 100 Lbs lighter, also attending to tyre pressure & S.A. adjustement. Squeaking Springs. Front. 2. In one case on chassis 4-LC. We had considerable trouble before we overcame the squeaking which was very pronounced. Firstly, we greased the springs in position. Secondly dismantled same, filed all ends of leaves where wear had taken place & then polished all leaves. Springs were O.K. for three weeks normal running, then commenced to squeak again. Complaint finally overcome by fitting new front springs (Firth) 100 Lbs stronger. Car now O.K. 2nd case exactly as above, only cured by fitting new Lemoine springs which slightly increased the camber (P.A.T.S.); positive. In our opinion, front springs appear to squeak or creak when same are on the weak side 1/2 negative camber or below. When front springs on the weak side are fitted the ends of the leaves soon begin to wear & form a "Ridge" consequently breaking the oil film. | ||
