steering box oil plug for E20

Post by headlight37 » Sat Aug 31, 2019 7:35 am

hello everyone!

Perhaps someone can help me with a oil plug for the steering box, because mine is worn out. (No.: 270906).
Maybe I have some luck. Alternatively we would have to create a replacement lock.

Many thanks in advance and greetings from Thuringia!
Jörn

Hello Marcel,

Thank you for responding to the search. Now we finally have photos.
The screw head was glued on provisionally, so that it finds hold first of all.
Therefore, photos of the thread are difficult, because the reattachment of the screw head is still less secure.
Would the diameter of the screw head be helpful?
Many thanks!
Jörn

Just a thought. Why not remove the oil plug and replace it with a rubber bung as a temporary measure until you have a new oil plug manufactured. Then at least you have the original part available for reference. All the best, Ranald

Thank you very much for the idea,
so I will probably proceed first of all, since oil must be refilled promptly. The steering has a lot of "play" which makes the handling over 40 miles very unsafe. Possibly also components of the steering gear must be reworked.
It is always interesting and exciting!
Many greetings
Jörn

It's highly likely that the thread is BSP ( British Standard Pipe). Blanking plugs can easily be obtained on places like eBay for around £3-4 with either an hexagon head or Allen key head.
The thing to know when measuring pipe threads is that the size relates to the bore of the pipe and not the diameter of the thread so you will need to look up a thread table. Alternatively let me know the diameter and I will tell you the size.

Hi, The play in the steering might be improved by removing a shim from the back cover of the steering box. Do you have a Bishop Gear box? You might be interested in a replacement part designed by Vintage MG Parts (http://www.vintagemgparts.com/bishop_cam.html). There are companies around who will recondition these boxes. Of course, the steering must be looked at as a whole, i.e. all moving parts......ball joints, king pins, track rods. If everything else works as it should, the steering play might not seem so bad. Regards, Ranald

Hello, Ranald,

thank you very much for your very valuable tips, which help us a lot.
I think I can decipher that it is a BURMANN patent due to the multiple colour coatings of the steering box. The adjustment possibilities seem to be more limited. In the coming week we are going to open the box and have a look. I'll be happy to get back to you, perhaps with new questions.
Many thanks for all your help and support!

Jörn
