ajh Posted January 17, 2014 Share Posted January 17, 2014 I'm just finishing up the new dash and need to decide if I re-use the original speed or put the 200TDI one in place which I'd prefer to do but I'd also like the option of getting a more modern VDO unit as well. Are there turnkey hall effect senders that will fit the Series 2 transmission or a hybrid speedo cable that'll let me run the 200TDI speedo available somewhere?

ejparrott Posted January 18, 2014 Share Posted January 18, 2014 TD5? Electronic. Problem is the Series motor's have the oil pressure, glowplug and charge lights in the speedo, nothing else does. Quote Link to comment Share on other sites More sharing options...
tacr2man Posted January 18, 2014 Share Posted January 18, 2014 You could use a trans ducer from a RRC efi , this had a cable drive speedo , with a transducer (pulse generator) in line dont think will work with Td5 speedo, but might be OK with VDO This is the part http://www.ebay.co.uk/itm/AMR3386-Speed-Transducer-for-Range-Rover-Discovery-ETC-with-speedo-cable-/151208903494?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item2334c0c346 Quote Link to comment Share on other sites More sharing options...
ejparrott Posted January 18, 2014 Share Posted January 18, 2014 I've had a thought during the day...I remember discussions about TD5 speedo's and transducers, but it might have been about fitting the transducer to the LT230 in my 109 and a TD5 head in the dash, so no it might not work for you, the transducer might not fit the SII box Quote Link to comment Share on other sites More sharing options...
missingsid Posted January 18, 2014 Share Posted January 18, 2014 This another thing on my list as my speedo is vastly out. What I thought was to make a round washer type thing that would use the three screws to hold it in with a stud and nut for ftting a later sender. I have not performed a physical check yet though. To use the RRC transducer would be a good option but you will need the plate off the old cable. IIRC the transducer has a short cable from gbox to it then a long cable to speedo which would not be needed. Alternative, look for digital speedo senders on line, there are lots for Harleys, these also have a short cable with a sender on the end and work with digital speedos. Is a SII/III the same fitting as SI? Marc Quote Link to comment Share on other sites More sharing options...
ajh Posted January 19, 2014 Author Share Posted January 19, 2014 I know the lights are not in the newer speedo units; I have a solution for this. Is the transfer case speedo cable end the same on both the Series and Defender? I know the retaining clip is different; but if I pull the Series cable will the Defender cable fit?

jad Posted January 19, 2014 Share Posted January 19, 2014 I believe the series cable is triangular? and fits in the defender lt230 but the defender cable is square and wont fit in the series transmission... Although everything I am sure can be modded! Waiting to be corrected! Jad Quote Link to comment Share on other sites More sharing options...
ajh Posted January 19, 2014 Author Share Posted January 19, 2014 If they are different in that way; who can manufacture a custom cable to fit? Quote Link to comment Share on other sites More sharing options...
western Posted January 19, 2014 Share Posted January 19, 2014 90/110 speedo cable inner has a square section at each end to fit speedo & transferbox drive gear shaft but the outer is circular http://www.lrseries.com/shop/product/listing/10054/PRC9872-SPEEDOCABLE-ASSY.html?search=speedo%20cable&page=2 Quote Link to comment Share on other sites More sharing options...
ajh Posted January 19, 2014 Author Share Posted January 19, 2014 Modifying the outer part is not a problem; if cut to fit will the rest 'work'? I'm trying to avoid taking it apart if I can't fit the new one in a reasonable time. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted January 19, 2014 Share Posted January 19, 2014 I believe the series cable is triangular? and fits in the defender lt230 but the defender cable is square and wont fit in the series transmission... Although everything I am sure can be modded! Waiting to be corrected! Jad I thought it was square too! Looking at The 109's, I need to order a new one...if I do I'll let you know!

Phil Hancock Posted January 19, 2014 Share Posted January 19, 2014 Series cables were square at both ends untill they changed to an almost elliptical shape at the box end during S3. But the gear in the transfer box did not change. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted January 21, 2014 Share Posted January 21, 2014 Ah...maybe that's why The 109's looks worn out then...maybe its meant to be that shape....will have to see if it works when I get the brakes sorted on that one! Quote Link to comment Share on other sites More sharing options...
Pollywog Posted January 21, 2014 Share Posted January 21, 2014 If you want a more modern looking speedo work out the TPM needed for your gearing and have a look at the aftermarket gauges available for Triumphs, MG's, etc. a lot of them use the same cable and there's a lot more choice of styles. I've fitted a Triumph Stag speedo to mine, I chose it as it looks virtually identical to the standard one but reads closer to my gearing.
