    Part #: Belt-4PK611779

    Ribbed Alternator Belt for BMW R Oilhead + Hexhead applications.
    Developed for & supplied as original equipment for BMW.

    Length = 611mm


    Vehicle Manufacturer: BMW

    Application: BMW R Series, 1992-2006

    Make/Model: BMW : R850, R1100, R1150, R1200

    Model Years: 1992-2006

    Vehicle Mfg. Part #: 12 31 1 341 779

    Original Equipment:     Part #  4PK611

    Technical Information:
    Continental Contitech specifically designed the Contitech Elastic technology for use on the non-tensioned BMW alternators. Use of any other manufacturers belt will not ensure proper tension over prolonged periods.
    Use of other brand belts can lead to
    a. Premature alternator bearing failure due to too tight of a belt tension.
    b. Belt slippage due to too loose of a belt tension.
    • Temperature-stable from -30 to 80 °C
    • Tropicalized - withstands high heat extremes
    • Extremely long service life
    • Conditionally oil-resistant
    • No retensioning necessary

    The Continental Contitech elastic ribbed belts are self-tensioning which cuts drive maintenance costs considerably.

    Alternator belts should be changed every 36,000 miles (60,000km) for proper maintenance.

    Length: 611mm

    We recommend you look at your old belt prior to ordering. In some cases, this belt applies to the later dual spark models. You may be able to confirm the correct belt if the BMW # 12 31 1 341 779 is still legible.
    The Continental Ref # 4PK611 should also be visible.
