Speedometer/odometer
I need a replacement speedometer in miles for my 1993 Volvo 240. The part No is K35200/3544611. I cannot buy new as it's obsolete. Can anybody help?

Sorry. I misquoted the Part No. It should be 39200/3544611

Does the whole thing not work or is it just the odometer? if it's just the odometer then replacement gears are available:
http://www.240turbo.com/240-odometer-repair.html If the speedo doesn't register speed at all then this website gives a good explanation of how to test the speedo/wiring/sender. I bought a 9v AC power supply from ebay for testing purposes http://cleanflametrap.com/speedoDiag.html https://www.ebay.co.uk/itm/NEW-LEI-P...QAAOSwklJa3a68 Cheers |

Thanks a mil. I will try these solutions. Our local engineer thinks it's a problem with the hybrid circuit (Grrrk to me!)

Unless the engineer has a specific reason for thinking it’s the hybrid circuit (not sure what that is) then it’s very likely to be a broken gear for the odometer. Yours is just one of squillions that have failed in this way.
Read through the explanation on the Dave Barton site- if you’re at all handy with screwdrivers etc then replacing the gear should take you more than an hour or so. Note- if you do take the speedo apart, take it apart somewhere as clean as possible, like your kitchen table not a workbench. The D'Arsonval movement (the mechanics of the movement of the needle) is vulnerable to foreign objects - notably little bits of metal, ie filings from grinding etc. Which will be attracted by the magnets and the result will be a speedo needle that sticks at certain speeds. Also note- you don’t need to remove the speedo needle, just undo the two screws holding the face in place and that will give you enough access to change the gear. Cheers |
