The Wacker Neuson Timing Gear is a genuine OEM component designed for PTS4V centrifugal trash pumps, GPS9700 and GPS8500 portable generators, GS8.5V and GS9.7V generators, and the RD11V hydrostatic double drum vibratory roller. As a factory-sourced part, the meets the original design tolerances and material specifications required for correct engine timing across all listed machines. This gear is the right choice when rebuilding or refreshing an engine that has seen heavy use in demanding pump, generator, or compaction applications. Confirm your model number against the fitment list before ordering to ensure a direct match.
Key Features
- Genuine OEM Tooth Profile & Material Grade — Manufactured to Wacker Neuson's original gear geometry and alloy spec, ensuring the timing relationship between engine components is maintained precisely as engineered.
- Cross-Family Engine Compatibility — A single part number covering PTS4V pumps, GPS8700/GPS9700/GPS8500 generators, GS-series generators, and the RD11V roller — all sharing the same engine platform.
- Drop-In Engine Fit — Indexes directly onto the existing crankshaft and camshaft gear train with no re-machining or shimming; retains the original timing marks for straightforward installation.
- Protects Valve Train & Injection Timing — A worn or damaged timing gear causes valve float, misfiring, and potential valve-to-piston contact; replacing it restores correct power stroke sequencing and protects the whole top end.
- Critical Engine Safety Component — Incorrect timing or gear slippage can cause uncontrolled engine runaway or catastrophic internal damage; using the genuine OEM gear eliminates dimensional variation that aftermarket sourcing can introduce.
The timing gear is a precision-machined component that synchronizes the rotation of the crankshaft and camshaft, ensuring intake and exhaust valves open and close at exactly the right point in each combustion cycle. On diesel and gasoline engines alike, even a small deviation in this timing causes misfires, power loss, excessive fuel consumption, and accelerated wear across the valve train and piston assembly. When a timing gear begins to wear — evident through rattling at idle, hard starting, or erratic engine behavior — prompt replacement with the correct OEM part prevents the damage from cascading into a full engine overhaul.
