nah never tryed, although I do know that there is a couple of members on here that have pulled them apart to free up gauges, have a hunt through the forums, and hang in the som1 will know how..
yea i have read that most of the time its the cg that turns the odometer ad the teeth break. there was brass ones for sale on ebay just dnt wana pull it apart and break it thats all lol
yeah they are really easy to fix, i fixed mine yesterday there is a really weak gear in the odometer motor with broken teeth, just replace it and will go again, my friend has a nissan pular and a skyline and they both have broken teeth, it's a piss easy job just look up odometer repair on google.
