Re Gleason Back Axle Bevels. X3457. -------------------- It would be a great advantage to be able to adopt Gleason bevels on axles on all type cars. We have gone into the question, and our conclusions and recommendations are as follows :- All 40/50 cars may be divided into three groups :- 1700 and onwards. } The present production wheels are interchangeable G.1908/9. 1200 to end of 1600. } Gleason gears can be cut out of the blanks which are now used on this Series (G.2300 bevel pinion, and G.1909 bevel wheel) without any alteration. 700 to end of 1100. } By changing the old (weak type) diff. box, axle shafts, and diff. pinions, and using the same (stronger type G.9/S) diff. box, as on the previously mentioned series, we can use also the same bevel wheel and pinion (G.2300 and G.1909), as at present used on this series. This means that for all our requirements we shall only require one type of wheels (other than production), and we think this will help considerably, and save complication. Series 500 } We do not propose to touch these. Our experience here shows that there is a great saving, both in time and money, in quietening these gears, and we shall be glad if you will consider our suggestions, and let us know what you advise.
