Gordon,

    The only "bushing" that I am aware of in = the front iron hsg would be the

eccentric shaft bearing in the front stationary gear...............It = is replaceable

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 st= ationary gear bore

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

requires a hydraulic press and a tool (either fabricated or purchased = from

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

dealer or machine shop..............
