CENTRAL PORTION. BY1-P6.10.21. XC4256 Will you kindly arrange to have the thrust washer for the bevel pinion keyed on the above chassis in a similar manner to that which we have adopted for the 40/50. It is essential of course, that the keyway be definitely wider than the key so that there is no risk of the washer being split by being forced on to a tight key. BY. {R.W. Bailey - Chief Engineer} | ||
