| -5- isfactory. Phantom II complaints are generally due to the excess of oil getting on to the commutator and in the dash pot. The lubrication system has received attention by the D.O. Item (16) Petrol Tank Leaks. We are reverting to the cheese headed screw on the filter cap to overcome the petrol leaks. There are very few complaints of leaks from any of the joints. Item (17) Radiator Leaks. Attention to the clearance of the mounting of the radiator by the Works has deleted most of the complaints. Every precaution is being taken in the soldering of the top tanks and generally this is now considered to be a good job. Item (18) Fan Pulleys. We have had no recurrent complaints after the fitting of bolts instead of rivets. Item (19) Noisy Oil Pumps. A depot sheet is being instructed for the fitting of a reservoir which entirely cures the noise on Phantom II. We have requested M.C. to try out the scheme on Phantom I as there are quite a number of these complaints. Cricklewood have been supplied with a number of reservoirs to cure any complaints that may arise on Phantom II. Item (20) Engine Overoiling, Piston Knocks & Piston Seizures. The work on the pistons with a larger skirt to lessen the piston knocks is receding. This, combined with the extra oil should overcome the troubles with seizure and knocks on future production. The fitting of the asbestos packing washer to the valve stem should lessen the overoiling troubles. Item (21) Dynamos. Work is being carried out on 25HP and Phantom dynamos to obtain a suitable output for all conditions of driving. The deletion of the trailed poles which on customer's cars has given the least trouble in regard to noise, output and over-heating is not a satisfactory issue from a complaint point of view. Out of approx. 300 dynamos in service with trailed poles there has only been two known cases of failure. The instructions issued for the present production of Phantom dynamos, that no notice must be taken of the blackening of the edge of the control brush does not seem to be correct when definitely known troubles of this kind have to be dealt with on customer's cars. | ||
