| - 2 - without oil filler cap, but at present cannot say that there is any improvement in oil consumption. Oil pipe from relief valve unit to timing gears - A hole has been chafed in this pipe by the front undershield at the corner where the pocket is rivetted on (off-side). The undershield is also rubbing on front engine case. Dynamo - From some cause, not yet ascertained, does not charge for the first twenty miles approx., early morning run, after which it functions O.K. We have examined commutator and cut-out - both seem to be O.K. Clutch - considerably improved. Jaggers have almost disappeared. It is only on reverse that these occur. We should say now that the clutch is equal to 40/50 HP. Stopping of clutch is O.K. when cold, but is sluggish when hot. Front axle - outside examination pivots and bearings O.K. Brake operating shafts with larger bearings - no wear is noticeable. Front spring clips - tightened up 3/4 of a turn. Off-side bottom two leaves worked out of line 1/4". These have been straightened. All leaves well lubricated, & all are O.K. UNDERSHIELD. Modified undershield to scheme 618/9/20. The cause of dirt getting in this shield is faulty fitting round the engine base and sides. It is imperative that it should be a good fit. Unfortunately, there is a big hole in this undershield for the starter motor, which in standard practice, will not be there, where a great deal of dirt gets on to present starter motor & chain. Handwritten note: V series production cars GEARBOX. Side shaft poor cold. Oil leaks out of tower where change speed spindle enters. Slight oil leak rear bearing. Starter motor chain taken up one notch on adjustment. Servo mechanism O.K. EXHAUST PIPES & SILENCERS. Exhaust lagging on rear & front silencers knocked up at front ends by stones. Otherwise lagging is O.K. Exhaust silencer brackets O.K. No blow at sliding joints. A better protection should be given to the sliding joint between the two silencers. This joint shews as much as 1/2" movement, & is always covered with dirt. Front sliding joint does not appear to do anything. EXHAUST CUT-OUT. This has recently stuck open, but closed itself in a short time. Dismantled and examined - chief cause is the weakening of the pull-off spring. Spindle shewed slight distortion. This also should be better protected, as on one occasion dirt was the cause of the sticking. | ||
