Why Choose 91101-HA0-004?

The one-way clutch bearing is a critical component of your Honda ATV's starter system. It allows the starter motor to engage and crank the engine, then free-wheels to prevent the starter from being over-driven once the engine starts .

A failed one-way bearing causes:

• Starter grinding noise – Bearing slips or locks up

• Engine won't crank – Starter spins but does not engage

• Hard starting / no-start condition

• Damage to starter clutch housing and ring gear

Genuine / Premium advantage:

• Precision dimensions – 61.8x46.8x12.7mm ensures correct roller cage fitment

• Hardened roller bearings – Resists brinelling and flat-spotting

• Correct spring tension – Reliable engagement and release

• Verified fitment – 115+ Honda ATV applications

⚠️ Supersession Note:

This part is the current OEM replacement for superseded number 91101-HA0-003 . Honda considers this part equivalent to the original. Ordering the old number may result in automatic substitution with 91101-HA0-004.

Pro Tip:

When replacing the one-way bearing, always inspect the starter clutch housing and starter ring gear for wear or damage. A failing bearing often contaminates the clutch assembly with metal debris.
