Last summer I had the front timing cover powder coated but recently noticed oil leaking from the bottom edge of the belt cover. I must have damaged the seal when it was fitted.
It's a sunny day so I'm changing the oil seal.
1 - GSA remove crash bars = remove beak and tank covers. GS no worries. To be fair, you might just get away with only taking off the middle tube.
2 - Tie centre stand to front wheel or use a bike lift. I have an Eazi-Rizer.
3 - remove the five little screws holding belt cover in place and marvel at how the edges have fretted your lovely new powder coat. To whoever it was suggesting washers between covers. Great idea wish I had done that.
4 - put gearbox into 6th gear and you need a friend to hold the brakes on. Also solidly chock back wheel.
5 - you need a hefty T bar with hinge joint and 33mm socket. Mine was too long and fat to clear the front shock bottom end. Thankfully a low cost extending wheel nut wrench did the job. Withe friend holding the brakes take up spring in transmission and whack the breaker bar with a lump hammer. Be careful exhaust & fork leg are very nearby. The nut comes loos suddenly.
6 - remove belt pulley and alternator belt. If seal has failed you will see oil in the recess.
7 - Drill seal at 9 o'clock and 3 o'clock. Screw in self tappers and pull out the seal. I used side cutter pliers to lever the seal out (not cutting the screws of course). My seal had lost 50% of the lip so I'm surprised oil want pouring out. Ideally use the BMW special tool to fit the new seal. It protects the seal lip. Last time, I used PVC tape and clearly it didn't work very well. Grease new seal and fit.
8 - Replace belt pulley and tighten nut. You'll need help as with loosening it.
9 - Refit alternator belt. I use a ratchet handle to turn the shaft and wind it on. Make sure the belt grooves line up on both pulleys.
10 - replace plastic cover. Stick penny washers to engine cover screw holes with grease. These will prevent the cover edges fretting your paint.
11 - Rebuild all the stuff you removed to get at the job and hope your new seal works ok.
Anyone worried about stone damage at the bottom centre (if your exhaust has no balance pipe) you could make a heat shield from thin ally sheet to trap under the belt cover bottom bolt.
