For internal transmission repairs, the crankcase must be separated (Section 11). Replace the countershaft and output driven gear as a set. When using the lock nut wrench, use a deflecting beam type torque wrench 14-20 inches long. The lock nut wrench increases the torque wrenche's leverage, so the torque wrench reading will be less than the torque actually applied to the lock nut. The specification given is the actual torque applied to the lock nut, not the reading on the torque wrench when used with the lock nut wrench. The torque wrench scale reading is given with the actual torque specification.
