MAJOR SERVICE:

For a Major Service, perform all of the service items called for in a minor service, and in

addition perform the following:

Change the Transmission Oil: With the bike fully warmed up, drain the transmission oil and

refill the transmission. The fill plug is readily identifiable on the right side of the transmission.

The drain plug is not in the bottom of the transmission, where it would dump oil onto the

catalytic converter and exhaust system. It is located beneath the fill plug on the right side of

the transmission, recessed into the “tunnel” cast into the lower right side of the transmission

case. BMW specifies 80, 90, or 80w90 wt gear oil. Consult your manual for the temperature

ranges. Fill the transmission to the bottom of the fill hole threads. This is a specified quantity

of 800cc. Use new sealing washers on the drain and fill plugs.

Change the Final Drive Oil: With the bike fully warmed up, drain the final drive oil and refill

the final drive. Use the same gear oil as for the transmission. Fill the final drive to the bottom

of the fill hole threads. This is a specified quantity of 230cc. Use new sealing washers on the

drain and fill plugs.

Renew the Air Filter.

Renew the Fuel Filter: The fuel filter is located inside the fuel tank. As an aside - when I first

serviced my K bike, I concluded that the fuel filter was installed in the most obnoxious manner

possible. I had to remove the entire gas tank filler cap and remove and replace the filter

located in the bottom of the tank. When I first serviced an R1100, I discovered that BMW had

devised an even more obnoxious location for the fuel filter.

Locate and identify the two fuel hoses and two vent hoses beneath the right side of the fuel

tank. Pull the two vent hoses loose at the inline connector. Clamp-off (I use small vice grips)

both rubber fuel lines forward of where they attach to the hard black lines to which they

connect. Remove the fuel lines where they connect and remove the tank. Drain the tank.

Locate the metal plate affixed to the side of the tank in the tunnel where the tank straddles the

engine. Remove the capscrews which attach the plate and fuel pump assembly to the tank.

Retract the plate about one inch from the tank and loosen the two vent hoses connected to the

inside of the plate, inside the tank. Carefully withdraw the fuel pump assembly - with the filter,

fuel pump, and fuel level float arm - from the tank. It will seem like you are trying to extract

about 7 inches of parts through a 5 inch hole - but by carefully positioning the float arm it will

all come out without bending or breaking anything, and without force.

Remove the old fuel filter and install the new filter. To reinstall the plate you will need to use a

new (large) sealing “O” ring for the plate. You will want to replace the crimp-on clamps on the

two vent hoses with two very small screw-type or spring-type hose clamps. WARNING: These

two vent hoses are submerged in gasoline inside the fuel tank. If the hose connections inside

the tank leak, then fuel will leak out through the vent hoses. If this happens, you will be

privileged to again remove the fuel tank and the fuel pump assembly to renew the clamps and

stop the leak.
