Although the Whitmores Compound used for this service was satisfactory, the Prices has been found to be unsuitable owing to its setting up an electrolytic action round the charge speed mechanism bush. Prices has now been discarded for both gear box and axle, and all gear boxes that have been run with a percentage of Prices are being specially cleaned out.
