Now for the engine oil. This is a job where there will be a lot of oil, some getting all over the place. In the alternative, it's only me that has this issue.
The K1600 engine has two separate oil drain plugs. One external, and one internal.
The internal crankcase oil plug is a standard BMW plug. A 5 mm Allen wrench removes it.
Use great caution when removing this plug because it only allows a 3 mm insertion of the wrench. Easy to strip, and easier to have fall off the wrench and may fall into the engine sump.
If the BMW OE crankcase oil plug is ruined by using an Allen extension that rounds out the hole, or the plug falls off the end of the Allen extension, you will get to remove the sump to remove the plug.
Anyway, back to the oil change.
Locate the sump drain under the engine.
An 8 mm Allen socket
removes this oil plug. About 4 quarts will quickly drain.
The sump drain plug is magnetic. Wipe any metal bits that have collected.
When the volume is emptied, and the oil is but a dribble, it is time to remove the crankcase oil plug.
What I do first though, is reinstall the drain plug and empty my oil drain pan. This keeps the 7 quart pan from getting too full, making emptying the pan even more messy.
At this point, I am going to show you the oil change I do with my bike. A change made easier because I replaced my BMW crankcase oil plug with my Super Plug.
I once again remove the sump plug and prepare to remove the Super Plug, using a 3" long 1/4" socket extension.
There is another quart of oil in the crankcase.
This is my Super Plug, the original test mule, firmly attached to the socket extension.
While the engine completely drains, I move over to the other side of the bike to replace the oil filter.
To make life easier, and spill less oil, I use a piece of heavy duty aluminum foil to protect the exhaust pipe and guide the waste oil into the drain pan.
You can see that I used my Wunderlich oil filter socket to loosen the filter, and allow it to drain a while.
My dealer mechanic uses a bit of cardboard.
Once removed, wipe any dirt away from the area.
Wipe a bit of oil on the oil filter gasket
. Install the new oil filter to where the gasket just touches the engine.
BMW says to torque the new oil filter to 11 NM
I follow the instructions on the oil filter, just like all the filters on my cars. Once the gasket touches the engine, I tighten the new oil filter 3/4 turn.
