Eccentric Shaft End Play?

FC Zach · 02-10-2011, 12:10 AM

The specifications within my Haynes manual specify that the "Standard" is .04 to .07 mm with a max of .09 mm. I started off with my "K" spacer and had a reading on my dial gauge of .015 (give or take .002 mm). I felt that may have been a little too tight so I borrowed an "X" spacer from jfaplanet and received a reading of .02 mm (maybe .002 mm more). IIRC the "S" and "T" spacers are uncommon and was wondering if the reading I received from the "X" (.02?) was good enough, or is it too tight still? ? ?

Here is a video if it works.

.0015" is what I shoot for. Basically a little tighter than Mazda's min. What are you torqueing the front nut to? You know you can tighten it a little more to snub it up a wee bit. I usually go for 110-115ft/lbs.

I didn't torque it at all, just ran a battery impact on it and the rear nut for a few seconds (probably around 90-100ft/lbs given the tools specs) just for fitment purposes but now that you mention it I can see the specified torque being crucial to the fitment process. Only thing is, is that will possibly get me a little less play. If you successfully run yours with a run-out of .0015mm with no issue then I'll stay with the "K" where I had the initial .015mm run-out and of coarse rechecking it after properly torquing the front and rear.

Sorry TT, misunderstanding on my part. I now see that you were stating your measurement in inches which is .038mm. So now my question is,

Who has a "S" or "T" spacer? Can these be purchased from Mazda still?

***TitaniumTT*** · 02-10-2011, 08:18 AM

Are you sure those are in mm and not inches? I can't tell from the vid. It's rare that spacers need to be changed out.... unless you changed bearings or rotors.... I'd try Rob @ Pineapple. He told me once that he has a drawer full of them if I needed an odd size. MT probably has them as well and I'm sure Ray Crowe can get them as well.

FC Zach · 02-10-2011, 10:04 AM

Yeah, all new bearings (came in the RX8 stat. gears). Just ordered some spacers from Atkins, got both S & T to be sure.

My5ABaby · 02-10-2011, 10:42 AM

So to clarify Zach, the issue is that your shaft isn't getting enough play?

Zing!

Wow! Should've seen that commin
