| SEMI-FLOATING AXLE - BENTLEY 50. Fitting and Assembly Criticisms. Design Remarks. 1. The gears can only be set for correct backlash and preload on the bearings by trial and correction, since preloading the bearings alters the backlash. 2. The bridge for the pinion nose bearing has a very poor location, and we suggest that further advantage be taken of the bore in the axle casing by providing a longer spigot in the bridge piece. In the event of undue fidgeting it may be desirable to specify the use of fitting bolts. 3. The number of taper pins securing the spring brackets appears to be excessive, and we recommend that the quantity be reduced. 4. The lock plate for the pinion bearing retaining nut should incorporate a number of tabs to facilitate locking. This plate would be more efficient if produced in a thicker gauge of material, since the present piece appears inadequate. 5. No provision is made for lubricating the axle shaft outer bearings. Is it assumed that the initial packing of grease will suffice during the life of the car? We would point out that should failure of this bearing occur it cannot be replaced without turning the pressed-on sleeve off the axle shaft. continued. | ||
