HOURGLASS STEERING BOX MOUNTING - Dennis Nicholas - 17-08-2021
Mutterings, ramblings and questions!
Am using the 1A6111 "Hourglass" steering box (Oct 1936 on). I don't need the 1A6129 brake pedal fulcrum pin that holds the rear of the box on because I have hydraulic brakes and clutch (BMC engine) so just using the special front bolt that has a round head with a locating flat cut on it and a larger diameter shoulder through the box ending in a 3/8 BSF threaded portion to take the nut -"bolt steering box to frame" 2K6201 (listed but not illustrated in parts book).
I am just putting back together after having striped car for rebuild many years ago. It looks like at the time of fitting I just bolted the box to the chassis with the special front bolt and a plain 3/8 bolt on the rear!!!!! ......a closer examination suggests that I should have the "reinforcement, steering box to frame" 1A6130 in list but 2K6130 labeled illustration, on the inside of the chassis channel because I see that the holes through the box are at 90 degrees to the centre line whereas the chassis slopes inwards so the bolts/nuts will be at an angle to the chassis and the 1A6130 would have remedied this by being a reverse wedge to that on the box. I rather suspect that I did not notice this all those years ago in the early 70s and the set up has been like it with the nuts uncomfortably askew and putting a bending strain on the threaded bits for the last 70,000 odd miles!!!! I also suspect I may have the 1A6130 somewhere in one of the many dark dirty, spider infested corners/boxes in my barns. I suspect I disregarded the wedge as being only required under the older type box to give the correct rake on some models.
So off to search deep and carefully for 1A6130 (2K6130).
I may yet be asking if anyone has that bit they can spare as being older and wiser do not fancy putting box back as was.
I was also hoping to put a distance piece between inner and outer chassis sides and using a long bolt across the rear to stiffen up.......another small job that has escalated.

Hi Dennis... does the bit you need look a bit like this... I can't find my parts list. I bought it a while back to use on my Speedex but changed my approach....

Hi Nick, That is the very bit. email me at nippyblue7 (at) yahoo .co.uk with price (2nd class postage will do) and how you would like paying - can do online bank transfer - and I will return email with address. ( replace (at) with @)
You will probably have noted that both holes are 3/8 inch in spite of the special front fixing bolt , which I have ok, having a larger diameter plane part that fits in the box but is turned down and threaded 3/8 BSF for a nut.
