Technical Details

Installation Note

Starter-system diagnosis and installation should be performed by a trained scooter technician. Disconnect the battery according to the service procedure before opening or removing starter-system components.

Before fitting:

• Compare the old and new part numbers
• Inspect the starter-pinion holder and mounting area
• Check the starter motor, armature and brushes
• Inspect the mating gear teeth for wear, chips or burrs
• Confirm the pinion moves and locks correctly in the intended direction
• Clean the starter housing without allowing dirt into the engine
• Replace damaged O-rings, packing and fasteners with exact parts

During assembly, use only the lubrication method and quantity specified in the scooter’s service procedure. Excess grease can attract contamination or interfere with starter-pinion movement. Do not force the assembly into a misaligned or damaged holder.

After installation, reconnect the battery, confirm normal starter engagement and listen for grinding, free-spinning or repeated impact noise. Do not continue operating the starter if the pinion fails to engage correctly, as this can damage the mating gears and starter motor.

Buyer-Focused FAQs

Can the part be installed only to check compatibility?
No. Confirm the EPC, physical design and related assembly before opening or installation.

What will be supplied?
One Hero Genuine component under part number 28120KPL901S, subject to the exact contents of the sealed manufacturer package.
