PILKIE Posted July 18, 2009 Report Share Posted July 18, 2009 Hi all. I went for a blast today to blow the cobwebs out,and do the req checks before Malvern arrives. PING!!! the speedo packed up! MMM?? A snapped cable methinks?,or come undone maybe? I popped the cable off the speedo,and it wasnt going round! Took the cover off the tunnel and undid the cable from angle drive,cable turns ok! BINGO!! Its gotta be the angle drive then!!! YEP! Took it off to find the cable snapped at the box/drive joint! Simple fix then!! Ive got a spare angle drive on a BW35 autobox I got as a spare for the P6 recently,and they are the same! Fitted it to the TR box,tried it,all ok, fitted the speedo cable to it, tried it,all OK,fitted the cable to the speedo,tried it,,,,, Nothing! I backtracked to find the replacement angle drive had broken the same way!! B~**£R!!! >>>>You know whats coming dont you!! <<<< YEP!!! The speedo head itself has seized up solid! BUM!! And I didnt check this out as a cause! Now luckily I have a spare early speedo I can fit, and,,, somewhere amongst all the parts stashed in the house I am sure I have another angle drive! An expensive mistake to make,as they aint cheap even s/h these days! Will have to search out a couple at the show to replace my spares. Meanwhile I can repair the bust one with an end of an old cable,or an oval nail as I did once before on my P6! that repair lasted for ages! SO!!! If your speedo packs up,make sure to check EVERYTHING out first and then replace the broken part!! Or you run the risk of breaking the replacement part,and if you have just forked out a few quid for a new part,It will cost you that again!! I'm off for a rummage in my spare parts room!! Only god know where it is!!! Quote Link to post Share on other sites
Booga Posted July 18, 2009 Report Share Posted July 18, 2009 Pilkie, Hope you can fix mine for me next week at Malvern - my needle is permanently stuck on 50 mph Regards Quote Link to post Share on other sites
Jersey Royal Posted July 18, 2009 Report Share Posted July 18, 2009 Dave, While the tunnel was off did you sort your reversing lights. What was the problemo. Cheers Guy Quote Link to post Share on other sites
PILKIE Posted July 18, 2009 Author Report Share Posted July 18, 2009 Dave, While the tunnel was off did you sort your reversing lights. What was the problemo. Cheers Guy Hi Guy. I only took the access panel off,but the problem is the switch is sticky,so it could do with taking off and lubricating,or replacing,I have a spare, its ok once its had a bit of use to loosen it up! But I will do it next time the cover comes right off!! Hi Booga. If you detach the cable from the speedo head does the inner cable go round ok? If so, you need a replacement speedo or yours overhauled. Am happy to fit you another speedo if you get one while at Malvern!! Time for me din-dins!! Dave Quote Link to post Share on other sites
MI5 Posted July 18, 2009 Report Share Posted July 18, 2009 You can easily fix those angle drives, if they haven't been fixed in the past. Fix only works once, unless you have a piece of cable. Quote Link to post Share on other sites
PILKIE Posted July 19, 2009 Author Report Share Posted July 19, 2009 (edited) I have fixed/repaired them in the past as I have mentioned! But I also like to have a couple of original properjobs in stock incase a repair fails! Anyone got a couple of spares knocking about ???

trfella Posted July 19, 2009 Report Share Posted July 19, 2009 HI Dave, So you now have a mileage reading of 20k? BTW - my reverse lights packed up the other week - were working fine up until that point Quote Link to post Share on other sites

PILKIE Posted July 19, 2009 Author Report Share Posted July 19, 2009 HI Dave, So you now have a mileage reading of 20k? BTW - my reverse lights packed up the other week - were working fine up until that point Actually the replacement reads 77K,the believed actual mileage of my car is 97k,,,82k at resto in 1985 when a s/h speedo zero'ed was fitted,done 15k since,and I was thinking about turning it round to 97k to more fit in with its actual mileage,but decided against fiddling with a good speedo!

88V8 Posted July 19, 2009 Report Share Posted July 19, 2009 If you have limited mileage insce, better photo the new & old speedos in case you get queried at renewal. Ivor Quote Link to post Share on other sites
PILKIE Posted July 20, 2009 Author Report Share Posted July 20, 2009 Good point Ivor,I will do that! Trfella, Re rev lights. Mine were stuck on,so a tad annoying for drivers behind me that got a little worried at junctions! I disconnect the wire if they wont go off before a trip. I will also have a play with the seized speedo to see if its fixable!!! Quote Link to post Share on other sites
