KPL & DUP Pumps & Pump Parts: repair it or replace it?
Pump problems usually show up as one side of the mower going weak, a pull to one side, or creeping in neutral.
| What it's doing | What's usually wrong | What to buy |
|---|---|---|
| Mower pulls to one side, worse when hot | Worn pump on the weak side, or the wheel motor on that side | Swap sides to confirm, then replace the pump or the motor |
| Creeps in neutral, won't center | Return spring, arm or plate worn or out of adjustment | Return springs / arm, then readjust neutral |
| No drive on one side | Bypass valve open, broken belt, or failed pump | Check bypass and belt first |
| Leaking at the input shaft | Shaft seal | Seal, or the pump if the shaft is worn |
Pumps are side- and rotation-specific (L/R, clockwise/counter-clockwise). Match the full part number on the pump label, or the OEM number, before ordering.

How to read your Tuff Torq tag
There's a white barcode label on the back of the transaxle (some tractors repeat it under the seat). It carries three numbers:
- Top left: the Tuff Torq part number. 11 characters, e.g. 7A646084181. This identifies the complete unit. Order a replacement by this number.
- Top right: the serial number. Repair kits and internal parts are chosen by serial, because Tuff Torq changed internals within the same model code.
- Bottom right: the OEM part number (John Deere AM/MIA, Husqvarna 5324xxxxx, MTD/Cub Cadet 618-xxxxx). If the top numbers are unreadable, this one gets us there too.
No tag at all? Your tractor's parts manual lists the transaxle under the OEM number, and our finder accepts the tractor model as a last resort.

KPL & DUP Pumps & Pump Parts questions we get every week
Is my Dixie Chopper / John Deere pump a Tuff Torq?
Many are. Dixie Chopper numbers such as 200051, 200052 and 200080, and several John Deere numbers, are Tuff Torq KPL or DUP pumps under the mower brand's number. Send us the OEM number and we'll match it.
Which Tuff Torq transaxle fits my John Deere, Husqvarna, Craftsman or Cub Cadet?
Look up your mower by brand and model: John Deere · Husqvarna & Craftsman · Cub Cadet, MTD & Troy-Bilt · Simplicity, Snapper & Massey Ferguson · Dixie Chopper, Toro & Exmark. Each table shows the Tuff Torq unit your model uses and the OEM number it replaces.
Left or right: how do I tell?
Check the label. L/R in the model (KPL-10AL vs KPL-10AR) refers to control-shaft side and rotation. Left and right pumps are not interchangeable.
Where do I find the Tuff Torq part number?
On the ID label on the transaxle case, usually on top or on the side near the input pulley. It shows the model (for example K57R) and an 11-digit part number (for example 7A646084020). Our part number guide shows where to look on each series.
