| contd :- -4- Bijur system are excellent. We shewed Hy.{Tom Haldenby - Plant Engineer} several parts off cars fitted with the system. For example :- Radiator supporting balls which generally wear rapidly stay perfect for 25,000 miles. Rear spring pivots and front brackets shew little or no wear. Water pump bearings (New PhantomCodename for PHANTOM I) shew no measureable wear in 15,000 miles. Also the gland packings stay tight. (10) Front shock absorber. On the present friction shock absorber we feed the top ball through a flexible metallic tube, a very messy scheme but available without altering the shock absorber. On the new hydraulics we are proposing to use two leather gland packings pinched up positively without a spring, and feed the oil between the packings, as on the water pump. The oil passes through the rocking shaft and down a pipe on the outside of the operating lever to the top ball. The connecting rod is arranged so that drainage from the top ball falls to the lower ball. A-10290 shews the scheme. Yours very truly. Maurice Olley. | ||
