ALL BALLS offers this engine bearing for HONDA TRX 250 EX SPORTRAX 2WD, TRX 250 X SPORTRAX 2WD, TRX 350 FE FOURTRAX RANCHER ES 4WD, TRX 350 FM FOURTRAX RANCHER 4WD, TRX 350 TE FOURTRAX RANCHER ES 2WD 2006-2012. The engine’s shafts run on ball or roller bearings in the cases. They carry heavy loads at high revs and eventually develop play.

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 on your HONDA TRX 250 X SPORTRAX 2WD?

On competition bikes the main bearings are replaced at every bottom-end rebuild, at the hours recommended by the manufacturer. With the cases open, spin each bearing by hand: the slightest rough spot means it must go.
