Today I started on the task of fitting my new stub axle, new bearings, and replacing the hub, which will then allow me to fit my new "used" brake caliper (with fresh seals that I installed last weekend) and then get me on the road again.
However, I have hit a couple of snags and would welcome some advice.
1) I fitted the stub axle with the supplied nyloc nut and washer. I looked around for a torque setting, in the Bentley manual, and online, without success. I saw that a GT6 needed 65 lb/ft, so was going to use that, but then discovered that I couldn't fit my torque wrench into the available space behind the nut anyway! So I ended up tightening it "bloody hard" i.e. just short of giving myself a hernia. Good?
2) I then came to fitting the inner bearing seal. This is a ring of felt held in a thin metal ring with a lip. Does the felt face outwards or inwards? I suppose outwards.
3) Does the felt need greasing? I assumed so.
4) Now, the big problem. I can't get the inner bearing to slide onto the stub axle: it will go up the taper, to the shoulder, then I can't push it any further. I'm afraid to tap it on in case I get it off-true and foul the stub axle's surface. I checked whether I could slide the bearing onto the old stub axle, and found that I could get it on only if I went from the vertical arm end. I checked the diameter of both stub axles with a micrometer, at the place where the bearing sits, and they were both 1" to within a thou. I applied some 1500 grit emery cloth carefully around the stub axle, but still no go.
What am I doing wrong? I can see a solution: remove the stub axle, put the inner bearing and seal on it, re-insert the stub axle and tighten, but that can't be right, can it?
Thanks chaps
