ALL BALLS Crankshaft Oil Seal Kit for YAMAHA WR 125, YZ 125 1986-2000

ALL BALLS offers this engine oil seal kit for YAMAHA WR 125, YZ 125 1986-2000. An oil seal (lip seal) is a rubber ring that seals around a rotating shaft. They are found on the crankshaft, gear shifter, water pump and output shaft.

Why replace the oil seals?

The benefits:

• Stop oil leaks around the shafts.
• On a 2-stroke, keep the crankcase sealed, which the engine needs to run properly.
• All the engine’s oil seals in one part number for a rebuild.

Why choose ALL BALLS?

Complete All Balls kits: low-friction bearings and steel-spring nitrile seals, everything you need in one box.

When should you replace the oil seals on your YAMAHA YZ 125?

Seepage around the shaft, a dropping oil level or, on a two-stroke, an idle that creeps up on its own are warning signs. The seal is also replaced every time the cases are split.
