The tamper bar on an asphalt paver screed works under constant impact load. Every stroke is transmitted through the eccentric connection, and any play in that joint is transferred directly to the mat as uneven density and visible marks. When the connection wears, no amount of screed adjustment brings the surface back.
This APOLLO eccentric connection universal joint shaft is built for the tamper bar drive of the AB600-2TV and AB600-3TV screed systems. It converts the rotary output of the tamper drive into the linear stroke of the tamper bar, holding alignment under the vibration and heat that define paving conditions.
| Fits Screed Model | AB600-2TV / AB600-3TV |
|---|---|
| Application | Tamper bar eccentric drive linkage, asphalt paver screed |
| Position | Eccentric connection between tamper drive shaft and tamper bar |
| Fitting | Direct replacement, no modification to existing components |
The shaft is dimensioned to the original connection envelope, so it installs into the standard mounting position with the existing bearing housing and coupling hardware. Verify the physical configuration of the removed assembly before ordering where a machine has been rebuilt with non-original parts.

When to replace: Replace the eccentric connection when you find visible play at the tamper bar linkage, a polished or stepped bearing journal, cracking at the offset transition, or when mat density varies across the paving width without a screed adjustment explaining it. Replacing the joint together with its bearing and coupling hardware is the reliable way to restore tamper stroke accuracy.
