Engine is on the bench. Time to clean.

144


Side note: couldn’t get the bash plate mounts off so propped the engine on a couple of 1x1 dowels.


145


Time to take the cam shaft sensor off.


146


Starter.


147


Looking good. Splines are smooth with no stepping.


148


Valve cover and gaskets come off next.


149


150


Book says to pull this gasket also but I don’t have a new one so it stays.


151


Spark plug wrench.


152


Loosen the plugs. Not part of the book process but I figured easier for the next step.


153


154


Set cylinder 1 to TDC. At this point you're suppose to check the valve clearances but mine were done two weeks ago. I'm calling them good and moving on.


155


156


Lock crank.


157


158


Remove Cam Shaft Bearing Cap. “working diagonally opposite sequence, uniformly slacken all nuts”. So corner to corner interior side to side. A little at a time until the tension is off.


159


Next the cam chain tensioner. (BTW it's a 22mm bolt....why....it's the only one that size. Couldn't BMW make do with a 21mm so we would have two bolts (swing arm). I don't want to be all crazy and think that a 17 mm to match the front axel or 24 mm to match the rear axel and oil drain plug would be reasonable.)


160


Using an appropriate tool (fuel line in my case), lift the intake cam shaft and work the chain off. Then lift the exhaust cam chain and work the chain off. The straws were not book but seem like a good idea. Care is needed to not bang the cams shafts.


161


162


Secure the cam chain.


163


Remove and store the shims. (Don't forget to block the oil ports with rags.)


164


165


Remove guide rail. The wear limit is .8mm. It’s hard to measure but looks good. there’s a little scoring at the top.


166


167


Counter sprocket comes off next. Fortunately my touratech 17T has holes that we used to assist in breaking the bolt loose. Because crank locking pin is in place you do not want to put pressure on the transmission to take this bolt out. Transmission is in neutral here.


168


169


At this point it’s time to flip the engine to remove the oil pan. But the top has delicate studs exposed. So Plan A was to lay the engine on the side but my friend has an engine frame so I’m taking a pause. Using card board we created a jig to see if his engine frame will work.


170


171


In the mean time. The water pump gear is not spinning right. This is odd so a check shows that the gear is spinning on the shaft but not turning the pump. On the list to check later.
