The Bomag 33180264 Spiral Spring is a genuine OEM component designed for BT 65 and BT 70 tampers. Sourced directly from Bomag, this spiral spring meets the exact specifications required to restore proper tension and mechanical response within the tamper's drive system. This part fits both the BT 65 and BT 70 tampers, making it the correct choice for technicians servicing either machine in the field or shop.
Key Features
- Genuine OEM Spring Specification — manufactured to Bomag's exact coil geometry and spring-rate requirements, ensuring correct tension output for the tamper's reciprocating mechanism
- Direct Drop-In Replacement — engineered to match the original mounting configuration of part number 33180264, allowing straightforward installation without modification
- Confirmed Fitment — verified for Bomag BT 65 and BT 70 tampers, covering both models in this rammer family
- Sustained Compaction Force — a properly functioning spiral spring maintains the consistent stroke energy the tamper needs to deliver effective compaction; a fatigued or broken spring causes erratic impact rhythm and reduced compaction depth
- Long-Term Durability — genuine OEM material grade resists fatigue cracking under the high-cycle stress environment typical of rammer operation, extending service intervals between spring replacements
The spiral spring is a core element of the tamper's drive and energy-return system, storing and releasing mechanical energy with each stroke cycle to maintain the machine's consistent up-and-down ramming action. When this spring weakens or breaks, the tamper loses impact rhythm, compaction force drops, and the machine may become difficult to control. Replacing a worn spiral spring with the correct Bomag OEM part restores full stroke energy and keeps the rammer operating at its rated performance level.
