| R.R. 493a (50m) (D.E. 175 25-9-24) J.H.D. EXPERIMENTAL REPORT. -3- Expl. No. REF: GWHl/Crn/E125 We have replaced this by our old box, which was quite sound except for dowel flange which was broken. The engine generally is still clean and free from oil leaks. FRONT AXLE. Modified axle pivots to N.sch.1896 - these are in good condition. Modified operating shaft with larger bearings to N.sch.1895 - there is no increase in wear since our last report. We consider these to be very good. Pull rods operating front brakes - these are in the same condition as previously reported. Operating shafts bolted to front axle - the wear has slightly increased, but we should consider these to be reasonably good. They do not rattle. FRONT ROAD SPRINGS. Since our last report the N.S. spring has been changed due to the failure of the 3rd. leaf - 2" rear of rear clip, which has run 9,654 miles. The O.S. spring is still O.K. the mileage of this spring being 9,904. Rear anchorage of N.S.F. spring - this was reported flange broken on our daily report 27.5.25., the mileage being 18,638. The old type flange which was fitted to replace same is still O.K. The O.S.F. anchorage is quite O.K. UNDERSHIELD. This has got considerably knocked about by stones, etc. EXHAUST SILENCERS. As previously reported, the front silencer is almost bare, the lagging having been practically torn off. The rear silencer lagging is in a similar condition. Silencer brackets are slightly bent, but are O.K. We notice that the sliding joint, fitted to front of front silencer, does not function. It is capable of working if circumstances warrant it, but apparently there is no expansion of the front exhaust pipe taking place at this point. The rear sliding joint, as previously reported, works through a distance of 1/2". EXHAUST CONDUIT. We have had no report of this sticking, since our last report. EXHAUST SNOUT. This is still quite satisfactory. contd. | ||
