Bulkhead steering column bush??
Discussion
over A beer!
Why did I feel like death the next day??
Must have been the dodgy fish!!
Ive just been out and measured my steering column and its coming up a smidge over 19mm on the micrometer, so I reckon this one will do it.

You will have to split the column from inside though, might not be the same on yours, and itll be quite easy to square up with a few washers/shims.

As I said in another thread that bush upgrade is bloody fantastic for such a simple change.
It transformed my wedge steering, especially at low speeds. Steering is lighter and much more precise.
To be fair though, the original plastic bush was totally knackered, but even so, I was surprised by the difference it makes.
So I would recommend everybody to do it !

The SD1 column is only 14mm diameter which is not a standard bore size for ball bearings so I had to use a larger one and sleeve it down.

And where the bloomin ell are you ,still waiting to place my order Ian and you could probably do a few more by the looks of things,be happy!The SD1 column is only 14mm diameter which is not a standard bore size for ball bearings so I had to use a larger one and sleeve it down.

With luck I should be around base this week so will try to make some progress on this. I dunno, bearings, airfilter mounts, indicator stalks... anyone would think I had some sort of business going...

Well if you don't mind Ian will you do me one as my column moves up and down faster than a Thai birds drawers. Beer tokens await.Dix
I got all the bits to do mine off the shelf at a bearing supplier including a bush to make the odd sized shaft fit the bearing internal diameter (complete with grub screws to lock it on); I think the shaft was imperial though (SD1). The spherical flanged bearing fitted the original hole in the fibreglass so no butchery was required, and I glued the bearing ID to the bush OD to make sure the bearing turns and not the bush.
In case it helps, I went to an automotive bearings and engine place, and described the new bearing kit to them (with a cartoon pic drawn by me)..
and the guy simply said "what internal diameter do you want", so I guess there is probably a range of sizes, and one might just fit the SD1 column ?? just a thought....

You could be right about it being an Imperial size, I can't find any notes that I may have made at the time. I do seem to recall that the next Metric ID up was 17mm so that was the size to which I turned my bush. I think I cross-drilled the bush so that the bearing inner race grubscrews bear directly on the column and not on the bush.My spherical bearing was slightly smaller than the bulkhead hole so I mounted it on a slab of alloy and sealed that to the bulkhead... same effect, maybe not quite as neat, but I don't recall any butchery being involved
Essentially that elliptical plate at left is one of a pair (the other not shown) that sandwich the sealed bearing around its major diameter - you can just make out that the OD is radiused so the bearing finds its own angle between the plates as you tighten the clamp screws.
The rectangular alloy plate is secured by the bolts that held the original plastic bush; two new bolts secure the elliptical plates through the alloy plate and the GRP. Quick squirt of sealant and no water leaks after 5 years
