| ( 7 ) GEARBOX. B.7. The gears were quiet and the gear change light and positive. Noticeable slack developed in the rear bearing of the 3rd motion shaft. The box was free from oil leaks. FRAME & FITTINGS. LOP. FB.1505. Incorporating:- N.S.4676 Improved fitting of Bumper Bar FB.2233/4 Front Dumb Irons. No weakness or trouble experienced. N.S.4167. Flexible Front Engine Mounting ex.

Support Ex.22823 Rubber Packing. The engine mounting had no adverse effect on the front end stability. It was most beneficial in suppressing roughness and vibration, and also had a silencing effect particularly at maximum r.p.m. The only objection was that torque reactions at low revs. were noticeable in the form of engine dither, but this was no more objectionable than the roughness experienced under the same conditions with the standard mounting. The starting handle did not line up correctly with the nose of the crankshaft. LeC.4670,78,4734. Petrol Filter on 2nd Crossmember. FB.2322 2nd Crossmember. The filter was not disturbed during the mileage. An exceptional amount of dirt was collected in the filter well, sufficient to cover four pennies. The filter gauze remained clear and the dirt caused no obstruction to the petrol flow. This indicates that under normal conditions, the filter could run indefinite periods without attention. FRONT BUMPERS. New Wilmot-Breeden Bumper. FB.2585 Assembly of Support studs. Leadweights secured by compressed rubber washers. The lead weights remained tight on the studs, but the complete weight assembly was constantly working loose in the | ||
