dougbgt6 Posted October 24, 2018 Report Share Posted October 24, 2018 I have a Moto Lita Steering wheel, the horn works the same way as the original system. A piston through the boss makes contact with a copper disk. However, the piston and disk squeak which ever way up the piston. Annoying!!!! I broke the Moto Lita centre push removing it, a poor design and am now on my second push. I like the Moto Lita but the horn mechanism is flimsy. I want to move the horn to a column stalk or something suitable. Has anybody done this? Doug Link to comment Share on other sites More sharing options...
johny Posted October 24, 2018 Report Share Posted October 24, 2018 might I suggest a smear of electrical contact grease on the copper disc. Bit difficult to source such a small quantity (might try an electrical repair shop) but will help maintain a good connection and stop squeak Link to comment Share on other sites More sharing options...
Ian Faulds Posted October 24, 2018 Report Share Posted October 24, 2018 Hi doug I guess you could fit a tr7 or late spit 1500 steering column and switches. That what I'll be doing with mine. Or simples way put a horn button on the dash. Link to comment Share on other sites More sharing options...
Ian Faulds Posted October 24, 2018 Report Share Posted October 24, 2018 Just thought wonder if you could buy the column overdrive switch and use that for the horn. They seem easy to find on the bay Link to comment Share on other sites More sharing options...

dougbgt6 Posted October 25, 2018 Author Report Share Posted October 25, 2018 Thanks guys (except Pete and Colin, obviously) Some good ideas. Lubricate the ring, (Oo er Mrs!) OK but it's going to happen again and I don't want to break another horn push fixing it. Dashboard horn, like it. Only a couple of £ , but I would have to drill a hole in the dashboard no room for error and I might live to regret doing it. Overdrive stalk, simplest and easy to wire, but how to fit it without getting in the way of the other stalks? Also the horn button really wants to be push and spring off. Late spitfire stalk, £38 does horn, indicators and lights. Don't need the lights, they're on the other stalk, but I don't have to wire them up. The column fitting looks very different will it fit? I'm gonna have to go look at one. Doug Link to comment Share on other sites More sharing options...

Gully Posted October 25, 2018 Report Share Posted October 25, 2018 I also have a Motolita steering wheel and boss with the same horn set up, but haven't encountered the difficulties you're having Doug. However, when I fitted mine I did end up adjusting the inner / outer column position to increase the separation between the back of the boss and the slip ring. It sounds to me as though the gap is too tight and the plastic housing catching / rubbing. I'd suggest a bit of adjustment before changing the horn set up altogether.

dougbgt6 Posted October 25, 2018 Author Report Share Posted October 25, 2018 Pete/Gully, It's not the upper part of the push that's the problem, it's the way it attaches to the innards, thin flimsy studs and tiny grippy washers. Slightest upward pressure and *!@!!*!! I'm sure I could fix the squeak, that's not the problem. The problem is the horn push mechanism, the original is slack enough to be easily removed, I took it off and on dozens of times for various reasons. Unfortunately the Motolita is so tight that it's easily broken. Decided against the Spitfire stalk, my indicator canceling lugs are on the RHD side so I think I need the RHD stalk. This only ran for a short time before they put it on the left. Consequently, hens teeth and silly money. So had a look at Ian's link and bought these and an overdrive stalk. https://www.ebay.co.uk/itm/A-PAIR-OF-STEERING-COLUMN-COWLS-FOR-TRIUMPH-TR4A-WITH-OVERDRIVE/332258916513?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 Doug Link to comment Share on other sites More sharing options...
Pete Lewis Posted October 25, 2018 Report Share Posted October 25, 2018 Brilliant, Doug , So now thats the Od on a stalk and the horns on the gearstick ????? Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted October 25, 2018 Author Report Share Posted October 25, 2018 Pete, Unfortunately I haven't got OD. But if I buy the bits, you could come and fit it for me. I'll make you a bacon sandwich? Doug Link to comment Share on other sites More sharing options...
Gully Posted October 25, 2018 Report Share Posted October 25, 2018 I'm slightly bemused - maybe mine has a different horn push? The push in the centre of mine is sealed and contains a switch which has a wire leading to the sprung brush ring sweep in the boss - the switch is mechanically independent of the sprung contact. I assumed yours was the same and the sweep bit was breaking, but sounds a different set up. Gully Link to comment Share on other sites More sharing options...
dougbgt6 Posted October 25, 2018 Author Report Share Posted October 25, 2018 Gully, My "sealed unit" has a thin strip of metal plate pressing on the sprung piston which "sweeps the boss". It sounds the same. The problem is the Motolita version " sealed unit" is an extraordinarily tight fit in the boss. The first time I took it out the sealed unit burst, it came apart, one of the three internal plastic studs broke off and all three captive washers broke. Unrepairable, had to buy a new one, quite cheap, which makes me think this is a common occurrence. This time it burst again, no broken studs but all washers broken. The sprung wire out the side of the unit which makes contact with the boss is far too tight and the "sealed unit" will break rather than allow itself to be lifted out. I can repair it this time, but it's clear the thing is not up to periodic removal. Doug Link to comment Share on other sites More sharing options...
Gully Posted October 26, 2018 Report Share Posted October 26, 2018 How odd. Mine has a lightly sprung contact clip at the side which holds the centre in place and a removable wire running from the back of the sealed unit to the sprung sweep ring contact. Pulls out easily - just need to look out for the wire pulling on the connection. Gully Link to comment Share on other sites More sharing options...
