The Shacman X5000 4010758-Compressor Assembly (Side-Mounted-Wp9) is a complete OEM air conditioning compressor kit for Shacman X5000 trucks with WP9 engines. This assembly includes the side‑mounted swash plate compressor and the essential O‑ring seal (C31TY0021). Designed to restore factory cooling performance, it ensures reliable cabin comfort in all climates. Direct replacement for failed or leaking units.
The O-ring (C31TY0021) is a high‑quality rubber sealing ring used specifically for the suction and discharge ports of the Shacman X5000 compressor assembly. Manufactured from HNBR (hydrogenated nitrile butadiene rubber), it provides excellent resistance to R134a refrigerant, PAG oil, and high temperatures up to 130°C. Inner diameter 14.3mm, cross‑section 2.4mm, hardness 70 Shore A. Two pieces are supplied with the compressor kit. The O‑ring ensures a leak‑tight seal between the compressor and AC hoses, preventing refrigerant loss and maintaining system pressure.

The Shacman X5000 4010758-Compressor Assembly (Side-Mounted-Wp9) is the heart of the truck’s air conditioning system. It compresses low‑pressure refrigerant gas into high‑pressure hot gas, enabling heat rejection through the condenser.
Original compressors often fail due to clutch bearing wear, shaft seal leakage, or internal swash plate damage. This assembly restores full cooling capacity and improves driver comfort.
The side‑mount design positions the compressor on the left side of the WP9 engine, driven by a dedicated poly‑V belt. It includes a magnetic clutch that engages only when AC is demanded.
All components are manufactured in an IATF 16949 certified facility, using original Shacman tooling and material specifications.

The O‑ring (C31TY0021) is supplied in pairs. It seals the connection between the compressor and the AC hoses, preventing refrigerant leaks.
Material: HNBR (hydrogenated nitrile), offering superior resistance to modern refrigerants and lubricants. Operating temperature -30°C to +130°C.
Dimensions: 14.3 mm ID × 2.4 mm cross‑section. Hardness 70 Shore A. Tensile strength >15 MPa. Color: green (indicating R134a compatibility).
Always replace O‑rings when servicing the compressor. Used rings may flatten or harden, leading to micro‑leaks. Our kit includes two fresh O‑rings.
Step 1: Recover refrigerant using certified equipment. Disconnect battery negative terminal. Remove the auxiliary drive belt.
Step 2: Unplug the clutch electrical connector. Using flare nut wrenches, disconnect suction and discharge hoses from the old compressor.
Step 3: Remove two M10 mounting bolts and take out the old compressor. Clean the mounting bracket surface.
Step 4: Install new O‑rings (C31TY0021) on the hose fittings. Lubricate with a drop of PAG oil to ensure proper seating.
Step 5: Position the new compressor assembly onto the bracket. Hand‑tighten bolts, then torque to 45 Nm. Reconnect hoses, torque to 25 Nm (suction) and 20 Nm (discharge).
Step 6: Reinstall the belt, adjust tension to 5‑7 mm deflection. Connect clutch plug. Evacuate system to 500 microns, then recharge with 1.2 kg R134a.
Step 7: Start engine, turn AC on. Verify vent temperature <6°C. Inspect hose connections with electronic leak detector.
Weak or warm air from vents – insufficient compression due to worn swash plate. New unit restores cold air output quickly.
Grinding noise when AC is off – failed clutch bearing. The new compressor has a sealed bearing with extended life.
Refrigerant smell inside cab – O‑ring leakage at compressor joints. Our genuine O‑rings eliminate this hazard.
Clutch not engaging – burnt coil or incorrect air gap. Pre‑set gap and new coil guarantee reliable engagement.
Compressor endurance: 2,000 hours continuous at 3,000 rpm and 80°C discharge. No performance loss, no seal leaks.
Clutch durability: 500,000 engagement cycles at 24V, 0.5 sec on/off. Coil temperature rise <30°C, no contact welding.
Vibration: ISO 16750‑3, random 10‑500Hz, 4.3 Grms, 48h. No structural cracks, fastener loosening, or refrigerant loss.
Corrosion: 720h salt spray on aluminum housing – coating intact, no pitting. O‑ring remained flexible, no swelling.
O‑ring compatibility: immersed in R134a + PAG oil at 120°C for 1000h. Volume swell <15%, tensile strength retention >80%.
Direct fit for Shacman X5000 models with WP9 diesel engine (9.5L, 350‑400 hp), years 2019‑2026. Both LHD and RHD versions.
Also compatible with X3000 using WP9 engine (verify side‑mount bracket). Not for WP10 or WP12 (different mounting pattern).
For trucks with rear‑mounted compressor, order variant 4010759. Confirm original part number before purchase.
Reduced downtime: pre‑oiled and sealed, installation time 2‑2.5 hours including refrigerant recharge. No extra oil measurement.
Lower lifecycle cost: OEM quality lasts 200,000+ miles. Aftermarket compressors often fail within 12 months due to poor seals.
Driver comfort: reliable AC reduces heat stress and fatigue, improving safety on long hauls in hot climates.
Simplified inventory: one part number covers compressor, clutch, and O‑rings. Bulk discounts for 5+ units.
Yes, two genuine O‑rings (C31TY0021) are included in the kit. They are pre‑lubricated and ready for installation.
R134a refrigerant and PAG46 oil. The compressor arrives pre‑charged with 200 ml PAG46. Do not add extra oil unless system has been flushed.
No, always install new O‑rings. Old rings may be compressed, hardened, or nicked, leading to leaks. Our kit provides fresh seals.
The gap is factory pre‑set to 0.5 mm and should not need adjustment. If adjustment is required, use shims (not included).
24 months unlimited mileage. Covers internal mechanical failure, seal leakage, clutch coil. Excludes improper installation or contamination.
Because the side‑mount bracket aligns perfectly with WP9 engine’s belt path, eliminating chirping and premature belt wear. The included O‑rings are color‑coded green for easy identification.
The compressor features a service valve layout that allows easy access for gauge connection even in tight engine bays. The clutch connector uses a standard two‑pin Deutsch terminal, compatible with original truck wiring.
Technical support: downloadable PDF includes torque specifications, belt routing diagram, and refrigerant capacity chart – available via catalog button.
Compressor housing is made from recycled aluminum (approx 40% post‑industrial). PAG oil is biodegradable. Packaging uses molded pulp and recycled cardboard, no styrofoam.
Restoring AC function instead of replacing entire HVAC system reduces waste. The compressor and O‑rings are 98% recyclable at end of life.
A Midwest US fleet operating 52 Shacman X5000 WP9 trucks experienced 40% compressor failure rate during summer months. After switching to the Shacman X5000 4010758-Compressor Assembly (Side-Mounted-Wp9), failures dropped to 2% over two years. The fleet reported average vent temperatures of 4°C (39°F) at 38°C ambient. Installation time per truck averaged 2.2 hours, saving over $15,000 in labor compared to troubleshooting and repairing old units. The inclusion of new O‑rings eliminated post‑installation refrigerant leaks.
Generic compressors often use low‑grade rubber seals that shrink or harden after one year, causing leaks. Our OEM compressor uses HNBR O‑rings rated for 10+ years. Aftermarket O‑rings may be made of NBR which is incompatible with PAG oil, leading to swelling and blockage. Our C31TY0021 O‑rings are specifically formulated for R134a systems. Generic compressors arrive without oil or with wrong viscosity, causing immediate wear. Our unit is pre‑filled with correct PAG46 oil and includes two spare O‑rings for future service.
