- About 15mins. This is something that takes patience. That brass bushing can be a pain in the ***

STEP 1

Since various cars use this gear we wont get into how to take the cluster apart in the tutorial. This is assuming you have already gotten to it and located the e1 12 tooth gear. Pictured below is the gear location on an e30 VDO unit (on motoversion its in a similar location but offset the other way).

STEP 2

Once you located the E1 gear. Take the cover off. On e30 cars its a flat, on e28s its a Philips. Mercedes various a bit.

STEP 3

Pull the E1 gear off by pulling straight up. DO NOT PRY! It will probably fall apart if its already not half way gone. You will then notice you are left with a brass bushing. Our replacement E1 gear does not require this as it fits snugly on the shaft that rotates it.

STEP 4

You will now use a pair of dikes to bend the brass bushing enough for it to slip out. To do this, squeeze lightly on one side of the gear, then rotate it and repeat it again. Keep repeating this process unit te gear is deformed enough to slip right off.

STEP 5
