Thread: stuffed steering series 1

can anybody help my 1952 series one has a worn out worm and brass nut in the steering box .How can I get it fixed or replaced, maybe with a later model box ? the thread in the nut is a five start thread and there does not appear to be a tap and die available or does someone know different !!!!!! any ideas or help would be greatly appreciated because I can only drive in straight lines at the moment !!

will do a full re-build of the box at an significant cost because you have to ship it over and back. Unfortunately they don't ship parts (or at least they didn't previously)

The later series one boxes (54) have a longer column which makes the driving position smaller.

The best option is to find a box that had the later steel worm and nut replacement installed. These seem to be more durable than the bronze nut style and are externally indistinguishable. But it does mean you have to go looking for donors.

If your box has an alloy housing, make sure you don't have a broken housing where it rivits onto the column.

You should also check that the bearings on the cross shaft are not worn, these will increase the slop and are easy to replace with undersize bearings to match the wear in the shaft.

(BTW: According to a mate and expert 1st class machinist, the 5 start of the bronze nut seems impossible to reproduce with a CNC because the lathe is always reacting to the tension and the threads are usually unsuccessful. Steering Services UK have a brooch for cutting the thread, but have said that once it wears out they won't be making another.

The steel on steel are a 2 start square cut thread, I do believe they would be reproduceable, but being an automotive steering assembly have to be certified.)
