Wacker Neuson 5000086398 Trim Seal, Radiator, Rear, 28.50

The Wacker Neuson Trim Seal, Radiator, Rear, 28.50 is a genuine OEM component designed for the RT560 and RT820 series vibratory trench rollers. Sourced directly from Wacker Neuson, this seal carries the same part number and specification as the original — so you know it fits and functions exactly as intended. Confirmed fitment spans multiple RT560 and RT820 configurations, including RT820HT variants. When your trench roller needs a radiator seal replacement, is the part to reach for.

Key Features

• OEM Material Integrity — Manufactured to Wacker Neuson's original compound and dimensional specification, ensuring the seal compresses and seats correctly against the radiator housing.
• Rear Radiator Position — Engineered specifically for the rear radiator mounting location on RT-series trench rollers, fitting flush into the existing channel without trimming or reworking.
• Broad RT-Series Coverage — Verified fitment across RT560 and RT820 vibratory trench roller models, including RT820HT high-temperature variants.
• Sealing Performance — Maintains a tight barrier between the radiator and surrounding panels to prevent debris ingress and protect the cooling system from contamination during trench compaction work.
• Cooling System Protection — A failed or missing radiator trim seal allows dirt, water, and fine material to bypass the radiator surround, accelerating overheating risk in demanding trench conditions.

A radiator trim seal forms the perimeter barrier between the radiator core and the machine's enclosure panels, channeling airflow through the radiator fins rather than allowing it to bypass around the edges. Without a properly seated seal, a significant portion of cooling airflow is lost, reducing the radiator's ability to shed heat — particularly during extended operation in tight trenches where ambient temperatures can build quickly. When this seal deteriorates, cracks, or pulls away from its seat, engine operating temperatures rise and the cooling system has to work harder to compensate, increasing the risk of thermal shutdown on the job.
