The following is the result of the firstday's running. The level of oil is 10 cc. less in the three dampers than what we have previously filled up to. Morning's run Front no leak. Near side rear slight weep. Off side rear no leak. Afternoon's run Both front slight weep same as previous N.S. 6 cc. O.S.F. not measurable Near side rear leak lost 18 cc. Off side rear no sign of leak from gland but a slight leak developed from plug at rear and where it has been drilled for conduit. RE BREATHERS We have been successfull with the breather. We enclose a sketch of the unit fitted. HYDRAULIC DAMPERS The 2nd scheme we fitted is still a 100% job. [Signature] G.W.H. | ||
