- the inner body 342 of the front endbell 356 is also formed to include a wall 346 that extends away from the recessed annular surface 344 (the wall 346 also forming a part of the inner body 342 that engages and retains the lip 300 of the ring gear 368, as described above).
- a wall 346 that extends away from the recessed annular surface 344 (the wall 346 also forming a part of the inner body 342 that engages and retains the lip 300 of the ring gear 368, as described above).
- an inner diameter of the wall 346 surrounds a portion of an outer diameter of the distal end 374 of the camshaft 372 such that the front endbell 356 pilots the camshaft 372.
- This configuration eliminates the need for a separate bearing and/or additional components to support the distal end 374 of the camshaft 372, thereby reducing the complexity and overall length of the tool 10.
