AlanG Posted February 26, 2015 Report Share Posted February 26, 2015 Can anybody advice best place to buy an angled speedo drive? I understand that quality on these can be an issue. Alan. Quote Link to post Share on other sites
cvtrian Posted February 26, 2015 Report Share Posted February 26, 2015 AlanT on this forum refurbishes angle drives to a better than new condition - I would suggest you try him first - send him a PM Regards Ian Quote Link to post Share on other sites
RogerH Posted February 26, 2015 Report Share Posted February 26, 2015 Hi AlanG, if AlanT does not come up trumps then Moss do have good ones in stock. Having said that if you buy it over the counter take it out of its packet and test it - pull the drive out and rotate, make sure the teeth stay engaged/no binding. Apply pressure to the drive and do the same. Don't forget to install the copper washer. I have also found that if the tolerances of the pinion square hole and drive square shaft are against you it may be difficult to fit/engage. It may be worth removing your pinion and take it with you to the shop for atrial fit. Roger Quote Link to post Share on other sites
AlanT Posted February 26, 2015 Report Share Posted February 26, 2015 (edited) The trick is to drive it from the "speedo" side. If the gears are poorly cut/fitted then it will jam. I don't have any free stock of repaired ones at present. So I can't give you a quick turnaround. If you buy a Moss one then I may be interested to buy your old one. Post a picture of it.

AlanT Posted February 26, 2015 Report Share Posted February 26, 2015 Just checked my stock. I have one with a loose wire that I could fix quite easily. It depends on whether you like the solid square-section instead of a flexy-wire. I sold one like this to a fellow forumite a few months back. I'll try to remember who it is.

AlanG Posted February 26, 2015 Author Report Share Posted February 26, 2015 Thanks Alan, That would be fine. Could you let me know price. Alan. Quote Link to post Share on other sites
AlanT Posted February 26, 2015 Report Share Posted February 26, 2015 See PM. Just a reminder to forumites that I am interested to buy broken ones of these. ESPECIALLY the Smiths original ones, which have by far and away the best gears. Quote Link to post Share on other sites
AlanT Posted February 27, 2015 Report Share Posted February 27, 2015 This poor thing came to me from a forumite. It was in bits, missing a circlip, worn out thrust washer and had been taken out because the wire-stub was rotating in the bevel-gear. These repro-drives seek to avoid the tricky crimping, used by Smiths, by spot-welding the wire-stub directly to the gear. High carbon content, large mass and soft-iron wire don't make a good welding proposition. You can see here that I have knocked the weld out of the gear: https://flic.kr/p/rmiMk1 and then fitted a brass-plug carrying a square central hole: https://flic.kr/p/qrBbkw This is a press-fit and stud-lock combination. Making one such brass part would be a pain but I made a batch of 12 and this means the labour required per part is not so bad. Never mind how I do the square hole! Here reassembled with a new thrust-washer, cilclip and suitable lubrication, it now runs nicely. https://flic.kr/p/r79Cvc https://flic.kr/p/roAEzv Note the solid central stub is made from easily replaced 3mm steel and is retained only by a small O-ring.

AlanG Posted February 27, 2015 Author Report Share Posted February 27, 2015 I suspect it's not as easy as you make it sound. Alan Quote Link to post Share on other sites
Chris59 Posted February 27, 2015 Report Share Posted February 27, 2015 @ AlanT, As promised, I'll bring 6 broken angle drives to Stoneleigh, 2 are originals. @ Alec or RogerH, is it possible to meet on the TRR stand on Sunday, if yes, at what time ? Quote Link to post Share on other sites
Alec Pringle Posted February 27, 2015 Report Share Posted February 27, 2015 Hi Chris, not going to Stoneleigh I'm afraid . . . . . sorry ! Cheers Alec Quote Link to post Share on other sites
RogerH Posted February 27, 2015 Report Share Posted February 27, 2015 Hi Chris, as PM'd - meet at 12pm at TR reg stand. Roger Quote Link to post Share on other sites
AlanT Posted February 27, 2015 Report Share Posted February 27, 2015 The only hard bit is making the brass bit with the square hole. This is too deep compared to its size for rotary-broaching. A 1/8in square push-broach would do it well but I can't get one. So I have to do them with a 1/8in end-mill. Quote Link to post Share on other sites
Superaquarama Posted March 1, 2015 Report Share Posted March 1, 2015 Out of interest, I just found an angle drive c/w cable in my 'stores', which I think came off a SIII XJ Jaguar. Just fitted it to the gearbox and the speedo and it seems to be perfect, but cannot test it as the car's not yet running. Quote Link to post Share on other sites
AlanT Posted March 1, 2015 Report Share Posted March 1, 2015 There are lots of different part-numbers for these. PM me and I'll email you a list of vehicles and numbers. One issue that may be important is the length of the wire-stub that sticks out. You might get a marginal connection or buckle up the wire. Just look into this a bit and satisfy yourself. I suppose its also possible they have different ratios which would screw up the calibration. Quote Link to post Share on other sites

AlanT Posted March 2, 2015 Report Share Posted March 2, 2015 Just what you want. Two of these dodgy things to go wrong. Seriously the fit of the wires into the recess in these is quite marginal. They form the "square" by squeezing in four dimples. Some are better formed than others. Then the whole wire-stub thing is fragile. They are not spring steel, they are iron wire and pretty soft. Lots of the broken ones have the wire-stub torn off where they are fixed into the gear. I believe they get torn off when reversing, judging by the lay of the wires.

Chris59 Posted March 3, 2015 Report Share Posted March 3, 2015 Today I've found another old, original angle drive in my stock (with torn wire-stub), obviously to late for Stoneleigh 2015 ! @ Roger, it was nice to see you again Quote Link to post Share on other sites

Besalu Posted March 17 Report Share Posted March 17 Is AlanT still around and selling these or can anyone suggest the best place where to acquire one? Bit of a nightmare i have had. One of the first things i did when i bought the car last year was to fit a new overdrive gearbox from Pete Cox. The speedo never worked from day 1 so bought a second hand one which i had recommissioned. I was down near Alicante recently with my mechanic doing a lot of little jobs. We tested the speedo and new cable (using a drill) before fitting it to the dash but forgot to test it again before putting the car back together. First test drive and the new speedo wasn't working. By this time i was already two days late getting home and didn't have the time (or desire) to take the H frame etc out again to have a look. My mechanic recons it is the angle drive that has gone even though it was a new one that came from Cox with the gearbox (120694 + 3H550 Angle Drive + washer) I am not a mechanic myself but i think i can manage to take the seats and H frame etc out again on my own. So i should be able to change the angle drive myself if this is what the actual problem is. Any suggestions of anything else to check before going ahead and buying a new angle drive? Thanks, Richard Quote Link to post Share on other sites
Lo100469 Posted March 17 Report Share Posted March 17 Hi Richard, this probably does not help a lot but maybe someone will jump in to give the right info. As you i struggle with angle drives, I’m on the 3rd one in 3000 miles. 2 failed and i suspect the third one is on its way out because the speed is too low by 20%. I do have a new one that looks like a square box, i will take a picture tomorrow. I do not recall where i bought it, but it was expensive and supposed to be The solution. the 3 I had failed were ordered by my mechanic, so i suspect they come from Moss or Rimmer. cheers, Laurent Quote Link to post Share on other sites
Ralph Whitaker Posted March 18 Report Share Posted March 18 I bought one off a seller on ebay, happy to say it is still going after 5000 miles or so. Speedograph Richfield have made their own which is a square boxy thing, have a look on their website. Ralph Quote Link to post Share on other sites
Besalu Posted March 18 Report Share Posted March 18 Thanks Gents for your replies. Have just bought a NOS Smiths angle drive off Ebay for a decent price so will try and fit this and hopefully my new speedo will work once and for all! Quote Link to post Share on other sites

I still have a spare original Smith one. I need to decide which one i sacrifice first..... Edited March 19 by Lo100469 Quote Link to post Share on other sites

Either will work well, the newer will probably outlast the original but you do need to alter the access panel to allow for the extra bulk of them. Stuart. Quote Link to post Share on other sites
