This means that the parts necessary for use in case of idling overheating complaints on chassis before 'E' series will only include the new fan, driving pulleys and belt. These pieces should be detailed as soon as possible as they will be required for use in case of complaints what-ever the results of further belt endurance. The EX. numbers which apply are - EX.24135 Arr.of blade assembly. EX.24136 Blades. EX.24145 Flange. EX.26731 Pulley (Fan). EX.28138 Pulley (Spring drive). RM{William Robotham - Chief Engineer}/Std. will supply particulars of belt. The modification to the flange (for balancing) and to the blades (for bedding on flange) which have been made on the latest wraith five blade fan should be included on the Ph.III details. When we issue the standardisation sheet for 'E' series, the same details will be applicable. Rm{William Robotham - Chief Engineer}/Std. | ||
