Rubber Buffer 1524771 Model 1503 for H3412 Road Rollers Joins Our Stock Range

Rubber Buffer 1524771 Model 1503 for H3412 Rollers Joins Our Stock Range

We have added the APOLLO rubber buffer 1524771, model 1503, to our stock of road roller vibration damping parts. The buffer is molded from a premium quality rubber compound and is supplied as a direct replacement for the drum and frame mounts on H3412 tandem road rollers.

The Job the Buffer Does

A tandem roller compacts asphalt by delivering vibration from an eccentric shaft inside the drum. That vibration must be transferred to the mat, not into the machine frame. The rubber buffers sit in the mounting points and act as the interface: they isolate the frame, the operator platform, the bearings and the fasteners from the high frequency load, and they keep the amplitude of the drum at the value the compaction specification was written around.

Rubber ages. After enough load cycles, heat and contact with fuel or hydraulic oil, a buffer hardens, cracks at the edges or takes a permanent set. Once that happens the isolation is lost and the symptoms appear quickly: fasteners working loose, cracked brackets, a noisier machine and an operator who can feel the drum through the platform. Inconsistent amplitude also shows up in the mat as uneven compaction and a surface that does not close properly.

Key Features of the 1524771 Buffer

• Premium quality rubber — selected for high resilience and low compression set, so damping performance holds up through long shifts in hot weather.
• Correct stiffness for H3412 mounts — keeps drum amplitude and compaction quality at the original design value instead of changing the machine behaviour.
• Oil, grease and ozone resistance — practical protection in the drum area where contamination is unavoidable.
• Molded bolt holes and locating faces — a straight drop-in fit with no reaming, shimming or modification.
• Durable under repeated load cycles — long replacement interval even on high utilisation paving and compaction fleets.

Technical Specifications

When to Replace the Buffers

1. Visible cracks, hardening or flattening of the rubber at the mounting faces.
2. Buffers replaced as a set for the drum mounts, since all positions see the same load history.
3. Any service that opens the drum area for bearing, scraper bar or water pump work.
4. After a machine has been sitting idle for a long period with the drum resting on the buffers.

Who Buys This Part

Paving contractors buy buffers to keep a roller in production during the season. Rental fleets stock them because a roller with failed mounts cannot be sent out. Distributors and equipment traders order small batches to serve local contractors who need the part within days rather than months. The buffer is also a sensible item to combine with drum bearings, scraper bars and water pumps in one consolidated shipment.
