The Wacker Neuson is a genuine OEM Throttle Collar Screw designed for BV35A-P backpack vibrators, PV35A pole vibrators, P35A and P31A power units, and the PG1 dewatering pump. As a direct OEM replacement, this screw is manufactured to the same specification as the original, ensuring correct fit and function without adjustment or modification. The covers a wide range of machine configurations across both standard and EU variants, making it the correct sourcing choice for mixed fleets. Keep a spare on hand to get throttle control restored quickly when the original wears or is lost.
Key Features
- Genuine OEM Specification: — Manufactured to the exact thread pitch and material grade of the original fastener, ensuring the throttle collar seats and locks correctly rather than stripping or backing out under vibration.
- Direct Bolt-In Replacement: — Replaces the original Throttle Collar Screw position-for-position on all compatible units, with no thread chasing or adapter hardware needed.
- Broad Model Coverage: — Confirmed fit across BV35A-P backpack vibrators, PV35A pole vibrators, P35A and P31A power units in both standard and EU configurations, plus the PG1 dewatering pump.
- Throttle Control Integrity: — A secure, correctly torqued collar screw holds the throttle setting firmly during operation; a worn or missing screw allows the collar to shift, causing erratic engine speed and loss of output control.
- Verified Part Number: — Sourced directly under Wacker Neuson part number 5000157506, eliminating guesswork when cross-referencing parts diagrams or service manuals.
The throttle collar screw secures the throttle collar to the throttle shaft on small-engine power units, locking the operator's speed selection in place during use. Without a properly functioning screw, the collar can rotate freely on the shaft, making it impossible to hold a consistent engine speed — which directly affects vibrator output, pump flow rate, or screed performance depending on the host machine. Replacing a worn, stripped, or missing screw with the correct OEM part restores positive throttle control and ensures the engine responds accurately to operator input.
