Duraflex Gator 21982
Replacement rear axle and retaining push nut. The wheel is a separate component.
Identify Duraflex Gator Tank Wheels, Rear Axles & Handles
A loose Gator waste-tank wheel, axle or tow bar can be difficult to identify once it is removed from the tank. The 16-, 23-, 29- and 38-gallon models use different rear-axle part numbers, while the 6- and 12-inch wheels are separate from many of their attaching parts. Compare the actual component before selecting a replacement.
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.
How to recognize the correct replacement
- Read the tank capacity: the four axle assemblies are different part numbers even when their shapes seem similar.
- Identify axle versus wheel: MPNs 21982, 21991, 21992 and 21995 refer to axle-and-push-nut parts; 21983 is a separate rear wheel.
- Inspect the front: 21988, 21997 and 21998 have distinct assembly or bearing descriptions. Compare what's missing.
- Check the tow point: 21987 is a tow bar; 21996 is a two-piece towing-handle assembly listed for compatible 29/38-gallon versions.
- Check wear: a damaged attachment or cracked tank mount needs attention, not merely a wheel of the same diameter.
