| Extract from R9/G17.10.21. X.4247 X.4219 17.10.21. GEAR BOX. X.4247 As regards the noisy Hyatt roller bearing on thegear box, we are pleased to hear that you hope to cure this by making it slightly freer. It is quite likely that many ball bearings are fitted up too tightly, which would result in rumbling, and perhaps destroying themselves before they become free. At the same time it would be very disastrous to have slack in such bearings when used for supporting gearing shafts. R.{Sir Henry Royce} | ||
