kiwi-jim Posted October 13, 2016 Report Share Posted October 13, 2016 Hi team, I am after your suggestions, I am reassembling my TR4 steering , the splined coupling at the top of the steering shaft is to big for the spline on the lower end of the steering column, I assume the spline at the base of the steering column has lost some thickness. As when I reverse the shaft the couplings fit perfectly the spline on the new steering rack itself. while the steering rack is new and the steering shaft looks new is it likely that the new parts have slightly bigger splines and couplings on them in relation to the original parts. Or is it more likely the spline on at the lower portion of the upper steering column is just worn. In which case how the hell do you get it out because I have had no luck so far Cheers jim Quote Link to post Share on other sites
stuart Posted October 13, 2016 Report Share Posted October 13, 2016 They do often get seized together, once the clamp is undone and removed it should move but it will take a lot of soaking in release oil and a lot of gentle persuasion. Stuart. Quote Link to post Share on other sites
RogerH Posted October 13, 2016 Report Share Posted October 13, 2016 Hi Jim, good luck on getting it all apart. Have a look at the attached picture. I found that the female splined part had a poor casting and would not crush down fully onto the male spline and would be loose. I machined a slot into the female body to allow the 'D' shape to actually move. Roger Quote Link to post Share on other sites
TR NIALL Posted October 13, 2016 Report Share Posted October 13, 2016 I see Revingtons now do an Uprated Shaft with all Metal Clamps. Quote Link to post Share on other sites
kiwi-jim Posted October 14, 2016 Author Report Share Posted October 14, 2016 thanks guys Stuart I have been soaking the part for close to two weeks now and its still frozen solid, Roger the issue you mentioned is exactly the problem I have the female spine dosent seem to crush down or close up at all, so thats what made me wonder if the new parts are the right size. Niall I have seen the new Revington shaft on their site i have just been concerned about whether the clamps would work correctly on the spline at the end of m steering column. Its not quite as easy to freight stuff back and forward to NZ. I would be interested to hear on anyone who has brought the new shaft and perhaps some close ups of the couplings. cheers Jim Quote Link to post Share on other sites
TR NIALL Posted October 14, 2016 Report Share Posted October 14, 2016 Jim,think the Solid Couplings are a Ford Escort part but as Roger says need a small bit of Work. Quote Link to post Share on other sites
RogerH Posted October 14, 2016 Report Share Posted October 14, 2016 Hi Jim, if you do the mod I showed, or similar, and remove any entrapped metal then the clamps work perfectly. Some people simply cut a hacksaw slot across the offending area. I think this is so unengineering. Roger Quote Link to post Share on other sites

RogerH Posted October 14, 2016 Report Share Posted October 14, 2016 Hi Pete, go out and buy a milling machine - you know you want one. Roger Quote Link to post Share on other sites
stillp Posted October 14, 2016 Report Share Posted October 14, 2016 Funny you should say that Roger - I've been to the Midlands Model Engineering exhibition today, and been drooling over various machinery, but I just don't have the space. Also SWMBO might have something to say, since I've just bought a sectional insulated garage door with opener... I'll have to let her buy a new handbag. Pete Quote Link to post Share on other sites

TR4A1965 Posted October 18, 2016 Report Share Posted October 18, 2016 http://www.revingtontr.com/product/rtr3634/name/steering-shaft-tr4-6 I will be giving this ago in December. Apparently it stops any vague feeling in the steering? My steering feels OK now but as I have to replace the upper bushes dash side I thought why not? I'll report back. Best.

ianc Posted October 18, 2016 Report Share Posted October 18, 2016 For many years now, I have been running my TR4, which has always had solid rack mountings (no squidgy rubber blocks!), with TR6-type universal joints at both ends of the steering column. There seems to be sufficient compliance in the tyres (195s on 5.5J steel wheels) to absorb road shocks. Ian Cornish Quote Link to post Share on other sites
keith1948 Posted October 18, 2016 Report Share Posted October 18, 2016 Penetrating oil and each day (yes it takes a while) drop the top part of the steering column end on onto a piece of wood a few times. The inner part will hit the wood while the outer part will try to keep moving. Eventually all you need is a couple of thou of movement to get it started. I had same problem once and took me a couple of weeks to release the 2 bits from each other. I seem to remember using a blow lamp as well to heat it up and then put it in the freezer to cool it down.

kiwi-jim Posted October 19, 2016 Author Report Share Posted October 19, 2016 Thanks Keith yes i can see that i will just have to keep trying to remove this way, I have tried heat two or three times and droping on wood soaking in penetrating oil but no wins so far will keep trying cheers Quote Link to post Share on other sites
stuartmac Posted October 19, 2016 Report Share Posted October 19, 2016 (edited) Ive got solid mounts with TR6 UJ's at either end of the column as above - as discussed in an earlier thread. The improvement in the feel of the steering was quite noticeable, with none of the anticipated shock etc over bumps - even with uprated springs, polybushes and 195 tyres. Maybe its all taken care of by the sprung steering wheel...... Edited October 19, 2016 by stuartmac Quote Link to post Share on other sites
kiwi-jim Posted November 5, 2016 Author Report Share Posted November 5, 2016 Hi Guys I still need help It would seem that when a put a Vernier over the diameter of the male spline on the steering rack end it is 14.3 mm dia approx, where as the dia of the male spline on the upper steering shaft is only 12.7mm hence the reason a cannot get the coupling on the on the middle part of the steering shaft to grip the spline even after slotting it Roger question can anyone advise me what is the Dia of their spline on the base of the upper steering column, so I know whether I have a rogue upper column for some reason cheers jim Quote Link to post Share on other sites
