One Way Bearing 14Mm Hex For Pullstart/Rotostart

This ONE WAY BEARING 14mm HEX is an original replacement part designed for the HPI Nitro Star G/F series. It ensures reliable power transfer from the pullstart or Roto Start to the engine crankshaft, so your nitro engine starts easily and efficiently again. Perfect if your old one-way bearing is slipping, spinning, or worn out.

Function and use
A one-way bearing (one-way clutch) allows the starter shaft to turn the engine in one direction (during starting), but disengages in the other direction when the engine is running. When this bearing wears out, the engine often can’t be turned over properly, or the starter shaft will just spin without engaging – and this 14mm HEX replacement bearing is the solution.

Important about size – 14mm vs. 12mm
This item is 14mm HEX. It is crucial that you match the size with your existing starting mechanism and backplate:

• If your engine uses a 14mm one-way bearing → this is the correct type.
• If you need a 12mm one-way bearing, you should instead use:
• Part #1430 (12mm One-Way Bearing)

Always check the manual for your engine or car, or measure your current one-way bearing before ordering.

When should you replace the one-way bearing?
Consider replacing your one-way bearing if you experience:

• The pullstart cord pulls easily, but the engine does not turn over properly
• Roto Start spins without “engaging” the engine
• Uneven or jerky feel when you pull the starter
• The starter slips when the engine is about to fire

A new one-way bearing provides significantly more reliable starting and can often “save” an engine that seems hard to start.
