Arguments over relief pressures on these loaders end with the factory numbers, and the 512-page Weidemann 2070 CX50, 2070 CX80 repair manual PDF (OEM ID 1000245276) is where Weidemann printed them. Replacement and repair procedures fill well over half the book, walking you through engine removal, hydraulic cylinder resealing, variable displacement pump service, axle removal, and center joint work on both the CX50 and CX80. Electrical circuit diagrams anchor the back sections with plug and contact assignments for each connector, next to the full hydraulic circuit diagram. Check steering pressure against the 190 bar setpoint before you condemn a pump, and pull wheel nuts to 285 Nm. A misread pressure test buys the second teardown. Bookmarked and text-searchable; confirm the spec before you order, and order once.

Weidemann 2070 CX50, 2070 CX80 Common Problems This Manual Covers
Weidemann 2070 wheel loader loses drive after high hours, no thrust uphill, wheel motors weak
Rule out hydrostatic drive pressure first before condemning wheel motors. Inspect drive shafts and axle mounts using the removal procedures starting on page 257. If an axle comes off, torque the securing bolts to 360 Nm on reinstall. Compare both wheel motors for case drain flow; the worn motor bypasses noticeably more oil.
Manual Section: Drive and Axles p. 257Lift arms slow to raise, weak bucket rollback, hydraulics sluggish when oil warms up
Check hydraulic oil level first; the tank holds 65 L and low oil aerates fast. Test primary pressure at the gear pump against the 210 bar setpoint on page 85. If pressure is low, replace the return filter and tighten the housing 1/6 turn past contact per page 254 before adjusting the relief.
Manual Section: Hydraulic System p. 193Engine starts hard when cold and lacks power pushing into the pile
Check the air filter and drain the fuel water separator before chasing bigger faults. Replace both fuel filters and bleed the system per the fuel system procedures starting on page 145. While you are in there, verify oil level; the Perkins in the CX50 takes 8.0 L on a change, per page 51.
Manual Section: Engine p. 145Steering feels heavy or slow, articulation joint groans when turning at low idle
Test steering pressure with the engine at full throttle; the setpoint is 190 bar per page 107. If pressure checks out, grease the articulation joint pins and inspect them for wear following the center joint procedures starting on page 273. Check the hydraulic tank sits at the full mark before condemning the steering unit.
Manual Section: Inspections, Maintenance Work and Troubleshooting p. 107Machine feels tippy on slopes, front end light when turning unloaded uphill
Match tire pressures side to side first; uneven tires change the tip line more than operators expect. Keep the load arm low and the bucket rolled back on grades. Verify rated operating capacity for your attachment against the technical data on page 49, and torque wheel nuts to 285 Nm after any wheel service.
Manual Section: Technical Data, Testing Equipment and Special Tools p. 49Frequently Asked Questions
