GOSHAWK BACK AXLE. Y4256 V3550 We are very desirous of knowing the results of experiments in pinion thrust bearings on Gos:11. You will remember that there are 3 types namely conventional double thrust washer, a New Departure bearing, and a deep groove journal bearing. We believe you have all or most of them going and we should like to know as soon as possible which type shews up the best, so that we may decide in connection with the improved 40/50 axle.
