22 manual typo?

[racer11]

my 22 ground to a halt a few days ago and ive been looking for the ball bearing to fix it(inside the diff housing, on the spur gears axel) on the exploded diagram that is in the manual (http://www.tlracing.com/ProdInfo/Fil..._explosion.pdf)
on page 4 i can see the part i need and it has the number LOSA6397, no where in the rest of the document does it say what part that is, the closest being right at the top with LOSA6937, is that the part i am looking for and is this a mistake? or am i missing something?

Thanks
