Exciter service is where a vibratory plate rebuild gets serious, and it is the heart of this Wacker Neuson BPU2540A repair manual PDF (OEM ID 0210448, 159 pages), which covers six BPU variants from the 25 through the 37. Full disassembly and assembly sequences run from the throttle Bowden cable to the base plate, with the exciter shafts alone taking roughly a third of the book. Build changes get their own chapters: the exciter from calendar week 15/2013, the centrifugal clutch from version 108. A fault table traces weak forward or reverse travel to the hydraulic control system. Hold 0.5 to 1.0 mm of clearance between the exciter shaft and its covers before you close the housing, then pull the eccentric weights to 69 Nm (standard) or 85 Nm (from CW 15/2013). Guess that torque and the eccentrics walk loose at full vibration. Bookmarked and searchable by keyword, this PDF gets your plate compacting again.

Wacker Neuson BPU2540, BPU2540A Common Problems This Manual Covers
Wacker Neuson BPU plate engine runs fine but base plate has no vibration, V-belt smells burnt
Check the vibration fault chart on page 155; a glazed V-belt or worn clutch lining kills the exciter drive. Remove the protective cage and inspect both, following the coupling and V-belt procedure starting on page 69. On reassembly, tighten the three centrifugal clutch hexagonal bolts to 10 Nm (page 79) and seat the belt fully before loading the plate.
Manual Section: Vibration Troubleshooting p. 155Engine will not start, or fires briefly and dies again after a short run
Check the engine fault table on page 155 first. Pull the spark plug, clean carbon off the electrode, and set the gap to 0.7-0.8 mm as shown on page 152. Drain and clean the fuel strainer cup per page 151, then confirm fresh fuel and an open fuel valve before cranking again.
Manual Section: Engine Troubleshooting p. 155Vibration is present but compaction force feels weak, plate leaves loose material behind
Check the exciter oil level per page 151; capacity is 0.6 L, and low or milky oil wears the bearings and steals amplitude. If the oil checks out, open the exciter and inspect the eccentric weights and roller bearings, then torque the eccentric weights to 69 Nm (standard, page 114) or 85 Nm (from CW 15/2013, page 142) on reassembly.
Manual Section: Exciter Maintenance p. 151Reverse travel slow or machine only creeps forward, control lever has little effect
Check the hydraulic oil level in the control system; it holds only 0.4 L (page 16), so a small leak matters. Inspect the center pole head and control lever for seepage and top up any loss. Follow the fault chart on page 155, which covers reverse speed, forward speed, and no-travel conditions in order.
Manual Section: Hydraulic Control System Troubleshooting p. 155Oil film around exciter housing and grease slung inside the belt guard
Drain the exciter and refill with exactly 0.6 L per page 151; overfilling forces oil past the seal rings. Replace the seal rings and O-rings whenever the covers come off, and check the 0.5-1.0 mm clearance between shaft and covers shown on page 111 before torquing the cover combination screws to 10 Nm (page 138).
Manual Section: Exciter Maintenance p. 151Frequently Asked Questions
What are the replacement specifications for the V-belt on a Wacker Neuson BPU2540, BPU2540A?
The V-belt (7) is replaced by removing the belt guard (8) and loosening the clutch drum (24). When replacing the V-belt, the distance between the clutch drums (24, 12) can be adjusted using two shim rings (25). For a new V-belt, both shim rings are set inward to provide the furthest distance between the drums. p. 80
What is the engine oil capacity for the Wacker Neuson BPU2540, BPU2540A vibratory plate?
The engine oil capacity for both the BPU 2540 and BPU 2540A models is 0.6 liters. When checking or filling the oil, the engine must be in a horizontal position. p. 16
What is the torque specification for the lifting eye coupling on the Wacker Neuson BPU2540, BPU2540A?
The lifting eye (2) must be attached to the protective cage using socket head cap screws (3) and hexagonal nuts (4) with a torque of 49 Nm. p. 73
What is the prescribed idling speed for the engine?
The prescribed idling speed for the engine is 1400 ± 150 rpm, which is set using the throttle stop screw after the pilot screw has been properly adjusted. p. 153
What is the required spark plug air gap on the Wacker Neuson BPU2540, BPU2540A vibratory plate?
The spark plug air gap should be measured with a thickness gauge and set to 0.7 - 0.8 mm. If the gap is incorrect, it can be adjusted by bending the side electrodes. p. 152
