Speedo bearing installation '01 ZR 800
Quick question - jack shaft bearing on the speedo side completely disintegrated and I have to install everything new, from the cable coupling to the speedo adapter. My question is regarding the position of the two triangular bearing retainers in relation to the tunnel wall. Are they both inside the tunnel, sandwiched around the bearing, or is one inside the tunnel and one outside the tunnel behind the speedo adapter? The manual (and parts diagram) is vague and unhelpful, although one picture in the manual shows the speedo adapter installed and there does not appear to be anything between it and the outer tunnel wall. On disassembly, they were both inside the tunnel, but then again, it completely disintegrated (and the installer left out the solder rings), so I'm hesitant to trust that it was installed correctly. One respected blogger posted instructions that suggest that one retainer goes inside the tunnel and the other outside, beween the tunnel wall and the speedo adapter. So I'm confused. It seems to me that if I put one outside the tunnel, the square neck of the bolts will protrude from the single inner flange and bite into the round hole in the tunnel wall when I tighten it. That won't happen if the retainers are doubled up inside the tunnel. So I'm thinking the order of parts from inside to out is: locking collar, inner retainer, bearing, outer retainer, solder ring, tunnel wall, speedo adapter. Any thoughts out there? Thanks!
