| -3- Rm{William Robotham - Chief Engineer}/Swd1.5/MH.{M. Huckerby}16.5.39. NO.5 TEST HOUSE. B.60 NO.1 UNIT. Complete cylinder head tests after combustion chamber mod. to Ex.1383 as carried out on previous head conditions to Rm{William Robotham - Chief Engineer}/Swd1.3/MH.{M. Huckerby}27.4.39. Duplex induction system to be fitted (SCD.1223) and carburation to be developed in accordance with instructions by Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation} B.80 NO.2 UNIT. Unit allotted for full investigation of crankshaft damper (a) R.R. Harmonic. (b) Studebaker. (c) Adapted Buick Harmonic damper (SCD.1275). Effect of load rating and inertia on crank oscillation. The best condition on each to be obtained in which condition we should check the effect of timing gear damping by fitting the slack camwheel. This should again be repeated, taking the camshaft oscillations. B.60 NO.3. On completion of damper tests on B80 No.2 unit the bed to be converted to a B.60 and the damper test to be repeated on this B.60 No.3 as carried out on the B.80. These tests should be taken up to 4500 R.P.M. NO.2 TEST HOUSE. B.II NO.4 UNIT. Oil consumption and "blow by" tests as per previous programme Rm{William Robotham - Chief Engineer}/Swd1.3/MH.{M.
