OEM Cleaner Drivetrain Repair + AquaNaut/PoolCleaner Fitment
- Genuine Hayward OEM large drive gear
- Current Hayward part number PVXH007
- Legacy/reference number 896584000-457
- Fits documented AquaNaut 200, 250, 400, and 450 applications
- Fits documented PoolCleaner / Poolvergnuegen 2-wheel and 4-wheel applications
- Individual drivetrain component for targeted cleaner repair
The Hayward PVXH007 Large Drive Gear is a genuine OEM replacement component used in select Hayward suction-side automatic pool cleaner drivetrains. Hayward identifies PVXH007 as the large drive gear, and current parts references also associate it with legacy number 896584000-457.
The large drive gear works with the cleaner's turbine, smaller drive gears, shaft-bearing assembly, wheel hubs, and steering components to transfer motion through the drivetrain. When the gear teeth become worn, chipped, or stripped, the cleaner may slip, move intermittently, or stop advancing even when suction is present.
Best For
- Hayward AquaNaut 200 cleaner repairs
- Hayward AquaNaut 250 cleaner repairs
- Hayward AquaNaut 400 and 450 cleaner repairs
- PoolCleaner / Poolvergnuegen 2-wheel cleaner repairs
- PoolCleaner / Poolvergnuegen 4-wheel cleaner repairs
- Replacing a confirmed worn or damaged large drive gear
Why This Gear Matters
Hayward's AquaNaut troubleshooting information specifically lists the large drive gear PVXH007 among the components to inspect when a cleaner wheel turns but ratchets or when drivetrain wear is suspected. Similar movement problems can also come from the front drive assembly, shaft bearings, wheel hubs, steering components, turbine parts, or smaller gears, so diagnose the drivetrain before replacing individual parts.
Common Signs to Inspect PVXH007
- Large gear teeth are rounded, chipped, or stripped
- Cleaner wheels ratchet or skip under load
- Cleaner stalls despite adequate suction
- Movement becomes intermittent or jerky
- Internal inspection confirms large-drive-gear wear

Compatibility & Fitment Notes
Current Hayward troubleshooting materials identify PVXH007 as the large drive gear in the AquaNaut drivetrain. Current distributor parts data documents use with AquaNaut 200, 250, 400, and 450 cleaners as well as PoolCleaner 2-wheel and 4-wheel models. Verify the cleaner model and existing gear before ordering, especially on older Poolvergnuegen-branded cleaners where legacy part numbers may appear.
Installation & Service Notes
Turn off the circulation system and remove the suction cleaner from operation before service. Open the cleaner according to the procedure for the exact model and confirm the large drive gear is worn or damaged before replacement. Inspect the small drive gears, turbine assembly, PVXH019SA shaft-bearing assembly, wheel hubs, and steering components while the cleaner is open.
Buy with Confidence
Benchmark Pool Supply helps customers match Hayward cleaner parts by current part number, legacy reference, cleaner model, and drivetrain symptoms. For PVXH007, confirm that your cleaner uses the large drive gear associated with the AquaNaut or PoolCleaner / Poolvergnuegen drivetrain before ordering.
Frequently Asked Questions
What is Hayward PVXH007?
PVXH007 is the genuine Hayward large drive gear used in compatible suction-side pool cleaner drivetrains.
What is the older reference number for PVXH007?
Current replacement references associate PVXH007 with legacy part number 896584000-457.
Which cleaners use Hayward PVXH007?
Current parts references document AquaNaut 200, 250, 400, and 450 cleaners plus PoolCleaner / Poolvergnuegen 2-wheel and 4-wheel applications.
Can a worn PVXH007 cause the cleaner to stop moving?
Yes. Worn or damaged gear teeth can cause ratcheting, slipping, intermittent movement, or stalling, although other drivetrain parts and suction issues can cause similar symptoms.
What should I inspect while replacing the large drive gear?
Inspect the small drive gears, turbine components, shaft-bearing assembly, wheel hubs, steering parts, and surrounding drivetrain for additional wear or damage.
