Today I am going to repair a speedometer on my 1986 Jetta Diesel. The Odometer no longer works. I have plenty of experience fixing this problem that happens on almost every Markl II diesel Volkswagen. This is not confined to diesels though and includes gasoline cars too. Most times it is a little 14 tooth plastic gear that gives out and cracks under stress and age and are very difficult to find and replace. Most people resort to gluing them back together with super glue and that works most times but does not hold up forever and will eventually fail. More and more I am able to find these gears on Ebay with the proliferation of 3-D printers and the like. On the other end of the odometer drive shaft there is the dreaded Pot Metal gear. This Gear is press fitted to the little shaft and will work loose over time causing the same issue that the plastic gear when it fails. To fix this you have to dismantle the speedometer head and remove the pot metal gear. To make the hole smaller so it can be pressed back on the shaft with no more slippage, I simply take the gear and lay it on its side and crush it on an anvil with a hammer and punch and then press it back on the end of the shaft ether in a vice or with a hammer and a 6mm socket. I have been working on these cars since 2003 and have take several years to refine this method of repair.

Nice video! Another Joe fixing mk2s! I thought I was the only one. Also a dinner fork works well for prying off the needle carefully.
Joe, I SURE hope you can help me. I've got an MK2 cluster that looks VERY similar to yours pictured (it's actually made by Jaeger and comes out of a 1991 Mexican Volkswagen bus… long story). The problem is that the speedometer works, but is very sluggish. It lags a lot and takes a few minutes to get up to the speed I'm traveling. It appears to keep the correct high speed, but at slow speeds, or when stopping it takes forever to drop all the way down. Any ideas? THANKS! (PS: I can email you a pic if you'd like).
Do you sell a speedo repaired already as mine has just stopped counting miles
mine shows 20kmh less than the actual speed by gps, i drive 100kmh and its 80kmh
hi joe, my 2007 vw rabbit has its odometer not working. i took the dash out and when i put the positive wire from the battery at the power wire at the dashboard, it moves, but when i put all the wires from dash toggither, it doesent. do you think theres some power missin on it?
Is the pot metal gear the Lead Odometer Gear? https://www.odometergears.com/products/Volkswagen/Mechanical+Speedometer/19
