ALL BALLS Crankshaft Bearing & Oil Seal Kit for SUZUKI JR 50, LT 50 QUADRUNNER 2WD, LTA 50 and KAWASAKI KFX 50 1978-2006

ALL BALLS offers this engine bearing and seal kit for SUZUKI JR 50, LT 50 QUADRUNNER 2WD, LTA 50 and KAWASAKI KFX 50 1978-2006. The crankshaft and gearbox shafts spin on bearings in the cases; oil seals keep the oil in around the shafts.

What is this bearing made of?

Races and balls (or rollers) in hardened chrome steel, 100Cr6 type: a very hard steel that withstands the fatigue of millions of engine revolutions.

• Open bearing: unsealed, it is lubricated and cooled by the engine oil; clean oil is its best protection.
• C3 / C4 internal clearance: slightly more clearance than normal for a hot engine’s expansion; always refit the original clearance.
• Limit: it dislikes dust and old oil; running short of oil destroys it within minutes.

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 bearings?

Unusual vibration, a deep knock that follows engine speed or play in the con-rod: the bottom end needs a rebuild.

The manufacturer publishes no hour interval for this model: have the con-rod play checked at every piston change. Cross-Mania guideline: rebuild the bottom end every 2 to 3 top-end rebuilds.
