Maytronics 9985050 Dolphin Yellow D1 Replacement Track
Genuine OEM Traction Track for Select Dolphin Robotic Cleaners
The Maytronics 9985050 yellow D1 track is a genuine OEM replacement drive track for select Dolphin robotic pool cleaners. It replaces a worn, stretched, cracked, or damaged track to help restore dependable traction and smoother cleaner movement.
This listing is for one yellow track. Fitment can vary by cleaner model and production version, so confirm part number 9985050 in the cleaner's parts diagram or on the original service record before ordering.
Important Quantity and Fitment Note
Quantity 1 means one track. A complete two-side replacement requires quantity 2. Dolphin model names were reused across different production versions, and some later cleaners use a different track. Do not order by color or model name alone. Confirm OEM part number 9985050 before installation.

Compatibility and Fitment
Part number 9985050 is commonly specified for select versions of the following Maytronics Dolphin robotic pool cleaners:
- Dolphin Diagnostic 2001
- Dolphin 2002 / Dynamic 2002
- Dolphin Diagnostic 3001
- Dolphin Advantage and Diagnostic Advantage
- Dolphin Deluxe and Deluxe CL1
- Dolphin Heavy Duty
- Dolphin Interactive
This is not a universal Dolphin track. Compatibility can change by production year, regional version, and internal drive configuration. Some later versions use a different track, including newer-model track part 9985006. Verify the cleaner's exact model, serial information, and parts diagram before ordering.
Common catalog cross-references include 3295-299, 614356, DL9985050, MAY-201-0005, MAY-201-9528, and 87-111-1208. Cross-reference numbers are provided for identification and should still be confirmed against the original cleaner.
What's Included?
- One genuine Maytronics 9985050 yellow D1 replacement track
Not included: a second track, pulleys, guide wheels, bearings, side panels, brushes, fasteners, tools, or other drive-system components.
When Should the Track Be Replaced?
Inspect the track when the robotic cleaner loses traction, moves unevenly, slips on the drive pulleys, repeatedly throws a track, or struggles to climb as it did previously.
- Visible cracking, tearing, or missing inner drive lugs
- A stretched or loose track that no longer stays centered
- Smooth or heavily worn tread surfaces
- One side of the cleaner moving differently from the other
- The track repeatedly walking off an otherwise correctly assembled drive system
A new track will not correct a damaged pulley, guide wheel, bearing, side cover, brush assembly, or motor problem. Inspect the complete drive path before ordering additional parts.
Installation Notes
- Disconnect the power supply and remove the cleaner from the pool.
- Allow the cleaner to drain and place it on a stable work surface.
- Follow the correct Maytronics service procedure for the cleaner's exact model and production version.
- Inspect the pulleys, guide wheels, bearings, brushes, and side covers before installing the new track.
- Seat the track evenly around the complete drive path and confirm that it rotates smoothly without binding.
- Reassemble all guards and covers before reconnecting power or returning the cleaner to the pool.
Installation difficulty varies by model. If the track is excessively tight, repeatedly walks off, or does not align with the drive components, stop and recheck the part number and cleaner version instead of forcing installation.
ATB Fitment Tip
The safest match is the manufacturer part number, not the track color. If the original track is missing or the cleaner has been repaired before, send Aqua Terra Backyard a clear photo of the cleaner's model label and the complete drive side before ordering.
Frequently Asked Questions
What is the Maytronics 9985050?
It is a genuine Maytronics yellow D1 replacement drive track for select Dolphin robotic pool cleaners.
Does quantity 1 include one track or a pair?
Quantity 1 includes one track. Order quantity 2 if both sides of the cleaner require replacement.
Should both tracks be replaced at the same time?
It is not always required, but replacing both may provide more even wear when both original tracks are the same age and similarly worn. Inspect both sides before deciding.
Does 9985050 fit every Dolphin pool cleaner?
No. Dolphin model names and drive systems vary. Confirm that the cleaner's parts diagram specifies 9985050 before ordering.
Does this track fit the Dolphin Sprite?
Some catalogs associate 9985050 with certain Sprite units, but Sprite fitment can be version-specific. Confirm by serial number, original part number, or the correct parts diagram before ordering.
Is this the same as the newer 9985006 track?
No. 9985050 is the yellow D1 track used on select older-platform cleaners. Some later cleaner versions use 9985006 or another track configuration.
Will a new track fix a cleaner that keeps throwing the track?
It may if the original track is stretched or damaged. Repeated derailment can also be caused by worn pulleys, guide wheels, bearings, brushes, side covers, or incorrect assembly, so inspect the complete drive system.
What warranty does Maytronics list for this part?
Maytronics currently lists a one-year warranty for part 9985050. Final coverage and claim eligibility are determined by the manufacturer's warranty terms.
