Duraflex Gator 21982
Replacement rear axle and retaining push nut. The wheel is a separate component.
Duraflex Gator Waste Tank Wheels, Axles & Tow Handles by Size
If a Gator portable waste tank no longer rolls or tows properly, identify whether the worn item is the rear axle, an individual wheel, the front wheel assembly or the towing handle. Duraflex uses different original-equipment numbers for these repairs, including capacity-specific rear axles.
Match the rear axle to tank capacity
These four parts are axles with retaining push nuts, not replacement wheels. Each part number corresponds to a different original tank capacity.
| Duraflex MPN | Tank size | Component |
|---|---|---|
| 21982 | 16-gallon Gator tank | Rear axle with push nut |
| 21991 | 23-gallon Gator tank | Rear axle with push nut |
| 21992 | 29-gallon Gator tank | Rear axle with push nut |
| 21995 | 38-gallon Gator tank | Rear axle with push nut |
Individual wheels, front assemblies and handles
Wheel diameter, included bearing and front-versus-rear mounting are separate specifications. A towing bar is not necessarily the same part as the handle assembly fitted to a different tank.
| MPN | Component | Listed application | Size or configuration |
|---|---|---|---|
| 21983 | Rear wheel | Compatible Gator rear-wheel assemblies | 12-inch outside diameter |
| 21988 | Front-wheel assembly with handle | Listed for compatible 29-/38-gallon versions | 6-inch wheel |
| 21997 | Front-wheel assembly | Listed for compatible 29-/38-gallon versions | 6-inch wheel |
| 21998 | Front wheel with bearing | Compatible Gator front-wheel arrangements | 6-inch outside diameter |
| 21987 | Tow bar | Compatible Gator portable waste tanks | Model-specific attachment |
| 21996 | Two-piece towing handle | Listed for compatible 29-/38-gallon versions | Two-piece handle arrangement |
Match the original rolling arrangement. The 29- and 38-gallon names appear on several front-wheel components, but those parts do not all include the same handle, bearing or mounting hardware. Check your tank's existing front-wheel setup and exact part number before ordering.
What to check before ordering
- Start with tank capacity: select 21982 for 16 gallons, 21991 for 23, 21992 for 29 and 21995 for 38 when replacing the listed rear axle.
- Separate wheels from axles: 21983 is a 12-inch rear wheel with bearing; the matching axle is not included.
- Check the front arrangement: 21988 is catalogued as an assembly with handle, 21997 as a front-wheel assembly and 21998 as an individual wheel with bearing.
- Compare towing hardware: 21987 and 21996 are distinct replacement components; compare attachment points with your original tank.
- Check the mounting: confirm the wheel or handle is compatible with the original axle, fasteners and tank body before installation.
