Dayton Hydraulic

Find OEM and aftermarket replacement parts for Dayton pallet trucks and material handling equipment. Dayton pallet jacks — distributed through Grainger and widely used in light-to-medium duty warehouse applications — share components with several common OEM platforms, making quality aftermarket parts readily available for most repairs.

Compatible Dayton models include: Dayton 2W399, 3Z326, 4W663, 5W608, and other standard-capacity manual and electric pallet truck models. Parts are matched by model number and serial number range.

Parts categories available:

  • Load Wheels & Steer Wheels — polyurethane and nylon replacements in standard Dayton sizes
  • Hydraulic Pump Units & Rebuild Kits — complete pump assemblies and seal kits for lift and lower function
  • Wheel Axles & Hardware — load axles, cross shafts, and retaining hardware
  • Handle & Tiller Assemblies — control handles and tiller arms for manual models
  • Electrical Components — switches, contactors, and wiring for electric Dayton models

How to identify the right Dayton part: Locate the model number and serial number on the data plate, typically found on the frame near the pump or handle pivot. Dayton pallet trucks are often manufactured by Multiton, BT Prime Mover, or similar OEMs — so your Dayton model number may cross-reference directly to an OEM part number. Use the model filter above or search by part number to find compatible parts.

All parts ship from our US warehouse. With 190+ Dayton-compatible SKUs in stock, most orders ship same or next business day.
