It is recommended whether you get the extended TBO or not. It is just better than the old ball bearing. Cap screw 841-983 $31.41 (Longer shoulder and harder metal) Spring 838-122 $7.81 oil pressure regulator cone 857-230 $30 (completely different from the ball bearing) looks like a mushroom with a hole in the top. -------- Roger Lee Tucson, Az.
