(see our installation instructions below) How do I know if I have a Motometer or VDO? The E30 chassis came with either a VDO or Motometer unit, unfortunately there is no specific year or model range to denote which one your car came with. There is a way to check, however. The first check is on the bezel for the gauge cluster right between the speedo and tach there should be a logo embossed there stating either VDO or Motometer. So long as the cluster has not been opened and a gauge swapped out this should be accurate to the model speedo/odo that is in the cluster. The 100% surefire way to know which version you have is to remove the cluster, open the case and on the circuit board on the back of the speedo/odo there should be a sticker or etching directly on the circuit board stating VDO or Motometer. With this information, you will know which gear set you will need! E30 MOTOMETER ODOMETER GEAR REPAIR INSTRUCTIONS This guide should only be used to help you as a suggested way to fix your equipment.

PLEASE NOTE: YOUR KIT'S GEAR COLOR'S MAY VARY FROM PICTURES ABOVE There are many small pieces involved with this. So proceed with caution, use common sense and proper safety measures. Please be aware that we are not responsible for any damages that happen. By using this guide you understand that we have made this only to make installation easier for you. However, due to the age of these things, every gauge cluster has been through a different life. TOOLS NEEDED: - assortment of philips screwdrivers - needle nose pliers - flat head screwdriver - a little patience TIME NEEDED: - About 45mins. This is something that takes patience. You're dealing with lots of tiny pieces. STEP 1 Remove the 9 philips screws in the back of your gauge. When placed down, be careful not to break the tabs! STEP 2 When removing the rear panel, take note of the two lower tabs and be sure to pull straight up or damage to connectors inside may happen. STEP 3 Remove the 4 philips screws that hold the odometer in place. Before you try to take out the cluster, do not forget the connector at the bottom. There are tabs that hold it in place. Once this is out you can pull straight out because there are connectors holding. DO NOT BEND! We found it's best if you hold the cluster as it was placed in the car that way it doesn't fall out. STEP 4 When the odometer is out, you will see the gears on the side. See the damage. STEP 5 There are two screws holding a clear cover over the gears. Remove them. STEP 6 The gears can then be replaced in the order they are taken out. They fit in an interlocking stacking setup. Notice that the gears are very soft and will fall apart as you try to remove them. NOTE: There is a brass bushing on the smaller 12 tooth gear. It's on the shaft and needs to be removed to install the new gear. You do not need this bushing with the new gear. DO NOT TRY TO PULL THE BUSHING OFF WITH ANY TOOLS AS THIS WILL DAMAGE THE MOTOR. The best way is to use a pair of plyers and lightly squeeze the bushing from one side, then the other. Then it will slip right out. Do not use too much force! Don't forget to install BOTH spacers to keep the gears spaced correctly! IF YOU DO NOT USE THE SPACERS THE GEARS WILL WALK AND STOP WORKING! DO NOT LOSE THESE! DO NOT PUSH IT ALL THE WAY DOWN AGAINST THE GEAR. THIS WILL CAUSE THE GEARS TO BE PINCHED AND NOT BE ABLE TO MOVE! STEP 7 Put together in reverse order. Be sure you have gotten all the old pieces of the gears out so you have no future problems. Before closing everything up be sure to run the gears by hand to make sure everything is right and working correctly. DO NOT APPLY PRESSURE TO THE SHAFT WHEN YOU INSTALL YOUR NEW E1 GEAR. It will be a tight fit by design. use a pair of needle-nose pliers to hold the shaft while you push the new gear on. Apply pressure will push on the motor causing potential damage. Detailed instructions on the E1 gear only can be found here ENJOY! No more guessing when the next oil change is!
