An item I have been meaning to
fix for some time is the steering head bearings. There is a distinct
"notch" in the movement at the straight ahead position. It is a minor
irritation and really only noticeable when going slow (eg filtering through
traffic) but since the forks were off I decided replace the bearings.
There are a couple of issues in
replacing the bearings. Firstly the rings that hold the yoke in place require a
special tool. I found that the adjuster for my FJ rear shock works perfectly
but I made one anyway. This will allow me use a torque wrench when re-fitting.
Secondly, and this is a pain, the lower bearing race is hard to remove. The upper one has a lip but the
lower one doesn't. The manual shows a special tool, presumably this expands to
grip the race.

The top bearing came out easily, surprisingly it's a ball bearing rather than a taper roller. |

The lower bearing race is difficult to remove..... |

The upper bearing race shows signs of small dents that caused the "notch". The taper bearings are better because they spread the load better. |
I removed the lower race by cutting into it with a grinding disc on a mini drill and splitting it with a chisel. Not subtle, but it worked. |

I made this using the old bearing to drive the new bearings onto the shaft. |
