| WH. from R.{Sir Henry Royce} ORIGINAL.. R1/W10.11.17. 4. X.2439 X.3213 Re - Water Pump Drive. With reference to water pump drive we feel sure this matter would be better if there was ample clearance left in the tooth of the worm wheel. Please arrange to have one cut with say 1/16" slack and then say whether you can break the drive. easy fit [written above crossed-out 'It'] would facilitate manufacture.
