I had my 1300 Junior( 1972 modell) on support trestles when I discovered that it was a bit jerky when rotating on the steering wheel.
I have opened the steering box and it looks good regardless of the wound / Pitting at the end of the shaft. It sure is this that has made me know jerky on steering.

What can I do about this? Try brushing it down to make it smooth? Do you have any idea / suggestions for doing so?

Thank
Regards

There are three ways to cope with this:
  • find a better one (easier said than done, but there are good ones around)
  • find a machinist who can weld the pitted end and machine it to the proper shape or grind it down to remove the pitting (harder to find!)
  • machine the end to use another type of bearing. This is described in another thread.
Make sure to use this opportunity to detect cracks on the steering box casing. They develop around any of the holes for the top cover or end caps. Short of using penetrant, close up digital photographs, once blown up on a screen, will let you see things invisible to the eye.

Hi, thanks for the reply.

Yes, the box needs to be checked, but it looks good. It holds the oil inside the box, but it can be cracking anyway. I'm going to have it checked by a specialist who checks it like that.

When it comes to pitting, it's not easy to fix where I live. Have to go round the local mechanical workshops and see if they can help me. Have placed purchase ad on new part or complete box, but think it can be difficult to get. They are starting to get more worth a gold :)
Option 2 is to insert a new bearing that you referred to. Thanks for your input.

I see that some of these shafts can have an unscrew / dismount "bearing screw". Am I wrong here? My shaft looks one part.

Some Burman steering boxes had a u-jointed coupling just before the box, making the steering column a separate part. These were used on US spec GTV and Berlina between ca. 1973-1975. These parts are even scarcer than the one piece shafts.

Beware, the steering column and shaft exists in two different lengths. It depends on the type of steering wheel your car was built with. The later cars like the 2000 series had a deep dished wheel for which the column was a few cm shorter. Your 1972 Junior came, I believe, with a fairly flat, two spoke plastic steering wheel.

Yes, that's what I thought someone had a link on the steering column just before the steering box. Thanks.

Got with me that there are different lengths, but what does belong I have to find out. Have to keep figuring this out and hope I can manage to fix this.
Thanks for the quick clarification.(y)(y)(y)

I would go with the timken option on that. Check your case as this is mine which is now for the bin. I thought it had one crack. Nope it had at least 4. These are fatigue failures caused by the minimum edge distance not being maintained for the hole. Wouldnt be allowed in an aircraft build. Wasted half a day welding.
