Wacker Neuson 5000158077 Wheel 305 x 69.9mm Bearing

The Wacker Neuson Wheel 305 x 69.9mm Bearing is a genuine OEM component designed for the GPS9700, GPS8500, GS8.5V, GS9.7V, and GS12Ai portable generator series. As a direct factory replacement, this bearing is built to the exact dimensional spec — 305 x 69.9mm — ensuring correct seating within the wheel assembly on these generators. Sourced directly from Wacker Neuson, part carries the same fit and material standards as the original installed at the factory. Whether you are servicing a GPS9700V with a wheel kit or restoring mobility to a GS8.5V unit, this is the correct replacement part for the job.

Key Features

• Exact Dimensional Match: — Machined to the 305 x 69.9mm specification, this bearing seats correctly in the wheel hub without shimming or adjustment.
• Genuine OEM Construction: — Meets the load rating and rotational tolerance required for a generator transport wheel bearing, which must handle repeated repositioning on uneven terrain.
• Broad GPS and GS Series Fitment: — Compatible across multiple configurations of the GPS9700, GPS8500, GS8.5V, GS9.7V, and GS12Ai portable generator families.
• Restores Full Wheel Function: — A worn or seized wheel bearing makes repositioning a heavy generator difficult and can cause premature wheel and axle wear; this replacement returns smooth, free-rolling movement.
• Verified Wacker Neuson Part Number: — OEM part number 5000158077 cross-references directly to the GPS9700, GPS8500, and GS series machine numbers, confirming you are ordering the right component.

The wheel bearing on a portable generator supports the full weight of the unit through the transport wheel assembly, allowing the machine to roll freely when moving between locations on a jobsite. It reduces friction between the rotating wheel and the fixed axle, and when it wears or corrodes, the wheel can seize, wobble, or become difficult to roll — putting unnecessary stress on the frame and wheel hub. Replacing a degraded bearing with a correctly sized OEM unit like the Wacker Neuson 5000158077 restores smooth wheel travel and protects the surrounding assembly from accelerated wear.
