When a DPU 130 comes back from a teardown in labeled boxes, the argument over what bolts on first ends here: this Wacker Neuson DPU 130 repair manual PDF is the 106-page factory reassembly book for the reversible vibratory plate. Roughly half the book is straight assembly procedure, rebuilding your machine system by system from hood hinges and battery through crossbeam, hydraulic tank, fuel valve, radiator, and starter motor down to the exciter itself. Upper mass hydraulic hoses go on in a numbered sequence, one through seven, and wiring harness drawings trace each cable from the electric connection box out to the engine and ground points. Torque the battery ground cable to 50 Nm, the hood's rubber bumpers to 30 Nm, and the Verbus ribbed screws to 25 Nm. Every hour spent guessing a hose route is an hour the plate isn't compacting. Bookmarked and text-searchable, the PDF puts the section you need one keyword away.

Wacker Neuson DPU 130 Common Problems This Manual Covers
Wacker Neuson DPU 130 engine stalls or bogs down when vibration is switched on
Check the fuel supply before blaming the exciter. Verify the fuel valve and filter line connections shown on page 25 are tight; the fuel valve hollow screws take 35 Nm (25.8 ft-lb.). Then run the throttle valve switching operation test starting on page 37 to confirm the cable pulls full RPM before vibration engages.
Manual Section: Assembly Diesel Valve and Diesel Filter p. 25Vibration output drops or quits under load while engine RPM stays steady
Check the hydraulic oil level at the sight glass first; the system holds 45 liters, and a low tank starves the exciter gear motor. Inspect the pressure hose connections at the exciter, covered on page 58. If flow checks out, pull the exciter and inspect the cylindrical roller bearings and toothed gears per page 83.
Manual Section: Exciter Assembly p. 83Oil weeping from the breather hose or pooling under the upper mass after a shift
Inspect the breather hose fitting; the hollow screw torques to 30 Nm (22.1 ft-lb.) on page 51, and a loose one weeps oil constantly. Replace the sealing washers while you are in there. If leakage continues, drain the hydraulic system per page 52 and inspect every hose end for cracking before refilling with 44 liters.
Manual Section: Upper Mass Hydraulic Hoses Assembly p. 51Starter motor clicks but the engine will not crank even with a fully charged battery
Check the battery ground cable connection first; it torques to 50 Nm (36.9 ft-lb.) per page 8, and a loose ground drops cranking amps fast. Then inspect the starter cable nut, torqued to 10 Nm (7.4 ft-lb.) on page 41. If connections are clean, remove the starter and check pinion gear engagement per page 40.
Manual Section: Starter Motor Assembly p. 40Engine overheats after an hour of compaction, coolant temperature warning on the display
Clean the radiator screen and check the combination radiator core for packed dust; the screen screws torque to 15 Nm (11.1 ft-lb.) on page 35. Inspect V-belt tension and the cooling fan per page 42; the fan screws take 10 Nm (7.4 ft-lb.). Verify coolant hose clamps are tight before refilling.
Manual Section: Assembly Engine Radiator p. 34Frequently Asked Questions
What are the replacement specifications for the handle assembly on a Wacker Neuson DPU 130?
To mount the handle to the hood lock, use an 8 mm Allen key. You must safeguard both socket head cap screws with Omnifit 100 M and torque them to 25 Nm (18.5 ft-lb.). p. 3
What is the required torque for the hydraulic oil drain plug on the Wacker Neuson DPU 130?
The larger hydraulic oil drain plug must be torqued to 55 Nm (40.6 ft-lb.) after draining the oil. p. 54
What is the engine oil capacity for the DPU 130?
The engine requires 3.2 liters (3.4 quarts) of engine oil, specifically Fuchs Titan Unic 10 W 40 MC (SAE10W40). p. 55
What is the hydraulic oil capacity for the DPU 130?
The hydraulic oil tank has a capacity of 45 liters (11.9 gallons) when factory filled, and you should replenish with 44 liters (11.9 gallons) of hydraulic oil. p. 52
What is the torque spec for the exciter cover screws on a Wacker Neuson DPU 130?
The cover is fastened to the exciter using 6 ribbed hexagon socket screws per exciter, which must be torqued to 85 Nm (62.7 ft-lb.) using an 8 mm Allen key. p. 58
