The Bomag 05660317 Tension Spring is a genuine OEM component designed for Bomag BT 50, BT 60, BT 65, and BT 70 tampers. Sourced directly from Bomag, this tension spring matches the original specification exactly, ensuring a drop-in replacement with no guesswork on fit or function. This part covers the full BT-series tamper lineup represented in Bomag's catalog, including the BT 50 Typ2 variant, making it a versatile stocking item for crews running mixed BT-series equipment.
Key Features
- Genuine OEM Spring Tension Rating — manufactured to Bomag's original load and extension specification, so the spring delivers the correct return force every cycle without stretching or fatiguing prematurely
- Direct OEM Replacement — engineered to install in the same mounting position as the factory spring, with matching hook geometry and wire diameter for a secure, tool-friendly swap
- Broad BT-Series Coverage — fits BT 50, BT 50 Typ2, BT 60, BT 65, and BT 70 tampers, consolidating compatibility across the most common Bomag rammer models in the field
- Consistent Compaction Stroke — a correctly tensioned spring maintains the rammer's rhythmic impact cycle; a worn or broken spring disrupts stroke consistency, reducing compaction output and increasing operator fatigue
- Verified by Part Number 05660317 — cross-reference against Bomag's catalog using part number 05660317 to confirm fitment before ordering and eliminate costly returns
The tension spring in a Bomag tamper plays a key role in the rammer's reciprocating mechanism, storing and releasing energy to sustain the machine's up-and-down impact stroke. When the spring is at the correct tension, the tamper delivers a consistent, powerful blow with each cycle, which is essential for proper trench backfill and confined-area compaction. A fatigued or broken tension spring causes the stroke to become irregular or cease altogether, stalling productivity and potentially causing uneven compaction that fails inspection.
