About BS500 Parts
Wacker BS500 Rammer Parts — OEM Replacement for BS500, BS500oi, and BS50-Series Jumping Jacks
The Wacker Neuson BS500 is a light-duty jumping jack tamper built for trench compaction, footing sub-bases, and tight-access cohesive soil work. It's widely used in landscaping, utility installation, and concrete prep. Despite being lighter than the BS600 and BS700, the BS500 takes the same pounding — and needs the same quality OEM replacement parts to stay reliable. DanseUSA has been an authorized Wacker Neuson dealer since 1981 and stocks a complete range of genuine BS500 repair parts.
BS500 Model Variants — Which One Do You Have?
Wacker has produced several versions of the BS500 platform. Check your data plate for the exact model and item number:
- BS500 — original 2-stroke model with pre-mixed fuel
- BS500oi — oil injection model; requires separate 2-stroke oil, not pre-mixed
- BS50-2 — compact 2-stroke jumping jack, 50kg class (also known as the "BS50" rammer)
- BS50-2i — improved BS50-2 with fuel injection
- BS50-4 / BS50-4As — 4-stroke jumping jack, Honda or Wacker engine, EPA-compliant

BS500 vs BS600 Parts Compatibility
Some consumable parts — particularly air filters, spark plugs, and certain fasteners — are shared between the BS500 and BS600. However, engine components, bellows, tamping shoes, and carburetors are model-specific. Never assume a BS600 part fits a BS500 without confirming via model and serial number. When in doubt, email us your data plate info and we'll confirm the correct OEM part number.
