| To Rm{William Robotham - Chief Engineer}/Wym.{G. Harold Whyman - Experimental Manager} from Rm{William Robotham - Chief Engineer}/Cr.{Mr Cra???ster / Mr Chichester} C R O B N T. will you please fill in on this sheet what tests you consider a new chassis should go through before going onto production. i.e. on the road, on the dynamometer and other test apparatus, with special regard to the sections you are responsible for. Rm{William Robotham - Chief Engineer}/Cr.{Mr Cra???ster / Mr Chichester} After a satisfactory period of "running in" and tuning up, first tests should consist of dynamometer work of the following nature:- 1 hr on 3rd Gear @ 2000 RPM FULL LOAD. 1 hr " 2nd " " " 1 hr " 1st " " " - Same load as 2nd Gear 4 hrs " TOP GEAR " 1000 " FULL LOAD. 4 hrs " " " 2000 " " 2 hrs " " " 2500 " " 1 hr " " " 3000 " " 1/2 hr " " " 3500 " " 1/4 hr. " " " 4000 " " At the conclusion of the dyno test, the various units of the chassis should be stripped for examination, and if in a satisfactory condition, re-erected for road tests. This does not apply to engine bearings, | ||
