Gordon,

if worn out of tolerance............It must = be pressed both out and in and = because

of a "tang" must be removed from = one side and installed from the other = side

while = making sure "tang" is aligned with the notch in the stationary = gear bore

which also aligns the oil feed holes in both = the bearing and = gear............Job

a vender such as "Mazdatrix", = "Atkins", etc) or farmed out to a local = "Mazda"
