Bob Owen Posted April 21, 2016 Report Share Posted April 21, 2016 Desperately need some help. Trying to remove Steering Column from spitfire 1500 (to replace upper and lower bushes). Am clear on procedure (via Workshop manual/Haynes Manual) but for the love of me I just cannot determine how to remove the Upper Column Clamp Bolts (UKC 7070).The workshop manual refers to cap screws, they look as if they are but with the "allen key centre" " filled in " !! See attached photo. So, no means to use allen key, spanner or whatever Would really appreciate some help on this ie how do I unscrew these ?? many thanks bob owen Link to comment Share on other sites More sharing options...
Bob Owen Posted April 21, 2016 Author Report Share Posted April 21, 2016 Think I may have answered my own question!!, are they shear screws ??(should not bed as the manual simply refers to cap screws and neither Rimmer or Moss refer to UKC 7070 as shear bolts) If so, how the hell do I remove them?

dougbgt6 Posted April 21, 2016 Report Share Posted April 21, 2016 Filled in with what is the question? Can you dig it out? Otherwise you'll have to drill them out. Link to comment Share on other sites More sharing options...
Clive Posted April 21, 2016 Report Share Posted April 21, 2016 No Doug, once the bolts are tight the head shears off so they can't be undone. Without ingenuity at least... Couple of suggestions. (1) cut a slot using a dremel/angle grinder/hacksaw blade etc and then a flat screwdriver. (2) get a sharp cold chisel and use that to "knock" the heads around. I have used both techniques (the latter on my Cavalier sports hatch nearly 30 years ago when the ingition barrel went t*ts up in a carpark 200 miles from home. Had to remove the lock as no breakdown/recovery and it was getting late. Then I managed with a screwdriver, somehow. Pure desperation I expect!)

Mjit Posted April 21, 2016 Report Share Posted April 21, 2016 Are you sure those are the correct bolts you're looking at? I've got the earlier type of column and it's not 100% clear from the parts calalogues but while the steering lock has shear bolts they may not be the same as the UKC7070s. They certainly aren't on the Mk IV. Link to comment Share on other sites More sharing options...
Bob Owen Posted April 21, 2016 Author Report Share Posted April 21, 2016 Thanks for responses. I am looking at the correct bolts for the steering column upper clamp, they should not be shear (according to Haynes etc) but if you look at the spec for UKC 7070 bolts via Google they pop up as Shear bolts. Guess I will need to act on Clive's suggestions and take my time....so much for the quick job of changing the steering column bushes !! Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 22, 2016 Report Share Posted April 22, 2016 If you only need a top bush press the new one in ontop of the old one is a fix done by many with column in situ, and leave the old bush in the tube pete Link to comment Share on other sites More sharing options...
Mjit Posted April 22, 2016 Report Share Posted April 22, 2016 There not shear bolts according to the Moss parts catalogue either. There should be 2x 152597 shear bolts holding the steering lock to the column and a separate pair of UKC7070 bolts for the clamp that holds the rack to the car. Looking at the diagram the speedo trip reset should be attached to one of the upper clamp bolts, as it is on the Mk IV. That said UKC7070 isn't a standard (or should that be Standard) bolt code...

Bob Owen Posted April 22, 2016 Author Report Share Posted April 22, 2016 yup Mjit I agree. It does look as though these are the original fit....maybe a Friday car and the factory had run out of the proper bolts !!! Link to comment Share on other sites More sharing options...
Mjit Posted April 22, 2016 Report Share Posted April 22, 2016 Not sure how tight these go before they shear but another option might be to drill 2 small holes and se if you can get in there with a pair of straight circlip pliers? Assuming just using the new top bush to push the old one down the column doesn't work for you. It's what I did Link to comment Share on other sites More sharing options...
Bob Owen Posted April 22, 2016 Author Report Share Posted April 22, 2016 Thanks for all responses, managed to use a centre punch to get a bit of movement and then just got a pair of mole grips to grip and finally turn them out bob Link to comment Share on other sites More sharing options...

Bob Owen Posted April 23, 2016 Author Report Share Posted April 23, 2016 So, that was the easy part !!!!, now got both bushes out, top one was in many pieces, bottom one rather slack. Howq do I get the new bottom bush back in..somehow need to compress the rubber pips and press it in with something !!, any thoughts??? Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 23, 2016 Report Share Posted April 23, 2016 a smear of lube will get the pips in a good smooth push should motivate the bush to pop in and after all that some after market ones are more slack than the old one joys of classics prevails Pete Link to comment Share on other sites More sharing options...
Bob Owen Posted April 23, 2016 Author Report Share Posted April 23, 2016 Is there a "right/wrong way" to put in the top bush, as my old one had disintegrated there was no way I could check it The new one (from MOSS) has slightly differing length slots at each end------photo attached Link to comment Share on other sites More sharing options...
Pete Lewis Posted April 24, 2016 Report Share Posted April 24, 2016 good question.... most fit them anyway up cant remember why there are slots parts list and manuals dont show a slot if the pip is offset get that to make the bush and tube positions are the right fit and dont worry about them Pete drive it day is calling Link to comment Share on other sites More sharing options...
Mjit Posted April 25, 2016 Report Share Posted April 25, 2016 Was a few years ago but think I more or less cut the pips off, or at least camfered their leading edges. If you're is as snug as mine was it's not like it was going to go anywhere without then pips (and it hasn't). Link to comment Share on other sites More sharing options...
Bob Owen Posted April 25, 2016 Author Report Share Posted April 25, 2016 Got it fitted, in the end even though it was a very snug fit, it slid in like a dream. I gave it a good smear of grease, then fitted the whole outer column assembly into a long sash cramp and with a 3/4" socket as the "pusher" it slid in easily as I screwed up the sash cramp Link to comment Share on other sites More sharing options...
