The cause of the first and the last axle failure of 1965 originated at local tensile stresses caused by grinding. Initially, in the specifications of O and A in Table 8, the machining allowance of 0.5 mm was ground, but since 1965 the first 0.35 mm was lathe turn machined and the final 0.15 mm was ground by a softer grindstone.

18.1 Introduction. Journal bearings are one of the most common types of hydrodynamic bearings. Their primary purpose is to support a rotating shaft. They are used in various subsystems in engines and power trains, for example for support of both crankshaft and camshaft. They are also used in the rocker shaft of rocker-arm valve train systems.

bearing journal. An improperly heat treated axle shaft may cause the bearing to create a grinding noise during operation, illuminate the Anti-Lock Brake System (ABS) warning lamp and eventually a left axle shaft fracture. If the left axle shaft fractures, wheel separation from the vehicle may occur. This could cause a crash without

Pull the wheel and brake drum. Now use a lever and fulcrum under the axle and try to pry the axle up, taking note of any movement. If it moves, bad bearing. Also, double check that the brake shoe retainer springs (the ones that hold the shoe against the backing plate) are in place and not broken.

Position the grinder's tool-rest about 1/8″ (3mm) from the wheel and secure it in place. Rotate the wheel by hand to verify it clears the tool-rest. Wearing a faceshield, turn on the grinder. 3.
