Title: timing chain cover
Post by: bizzaro on June 06, 2015, 08:30:46 AM

1994 k1100lt. Can anyone tell me if I can remove and reseal the timing chain cover with the oil/water pump and the Hall transmitter(what the hell is that?)still attached?  The cover is leaking but the pump is solid.  I am looking to do less labor and more riding.  I just did the famous clutch boot to stop the bleeding in the rear of my ride. All good there, now I am now looking to stop :falldown: the oil bleeding in the front!

Hall effect sensor must be removed, as the rotor and disc (3 x M4 screws) behind the HES must be removed.
Waterpump cover can stay, but it would be a whole lot easier to guide the wire for the oil pressure sensor
behind the cover.....if the cover is removed.

Thanks...hope to get to it today or tomorrow.  Yea and I guess I may as well reseal the pump cover and housing as well, especially if I don't have to dismantle it? Can  it come off as a unit?  (the oil/water pump).

I LOVE the BRICK!!!!!!! no Really. :yes

Here is a pretty good description of Hall Effect Sensor (from BMW Motorcycle Owners of Alabama forum):

"First what is the Haul Effects Sensor? In simple terms, on the oil heads (the only ones I know about) there are two Haul effects sensors mounded on a steel place the fits on the front of the oilhead engine behind the drive pulley for the alternator. These sensors sense Top Dead Center (TDC) and 180 degrees on the crankshaft. On sensing these positions a signal is sent via wiring to the Motronic unit which in turn tells the coils to fire the appropriate spark plug and to squirt an appropriate amount of fuel through the fuel injectors. Of course the Motronic unit is monitoring a whole bunch of other crap such as battery voltage, oxygen sensor, etc."

Here's the forum URL if you'd like to read more:  http://forums.bmwmoal.org/showthread.php?868-Hall-Effects-Sensor-Failure


FYI, I also searched "hall effect" in Motobrick Wrenching > The Workshop and found 34 (!) entries.

The cover is mounted with 9 screws...the pump with another 6 screws, the 2 long one under the cover
can be very stubborn.
