Parts for your 2021 Haval H6-Thrust bearing

2021 Haval H6 thrust bearing – what it is, and when it matters

Based on the Great Wall Motors H6 (3rd Gen) workshop literature for the GW4B15/GW4N20 engines and technical material on wet 7‑speed dual‑clutch units used in the H6, a thrust bearing is indeed present on the 2021 Haval H6. It’s the crankshaft thrust bearing (thrust faces built into a main bearing), controlling end float of the crank. There isn’t a traditional clutch release/“throwout” thrust bearing as seen in manual gearboxes, the H6’s wet 7DCT or hybrid drivetrains use internal release mechanisms serviced as assemblies. In short, the thrust bearing exists, but it’s an internal engine component rather than a routine service part.

On the 2021 Haval H6, the thrust bearing’s job is to keep the crankshaft centred fore‑and‑aft, so the rotating assembly runs true and the transmission input and timing gear stay happy. It’s integral to one of the main bearing shells, and it rides an oil film just like the rest of the mains. When oil quality is good and levels are kept up, they’ll usually last the life of the engine.

For servicing, owners won’t find a “thrust bearing” listed like a filter or belt. It isn’t inspected as a separate item at scheduled services. However, good oil practice directly protects it: stick to the specified viscosity, change intervals, and use quality oil and filters. If a workshop is chasing bottom‑end noise or excessive crank end float, they’ll measure it with a dial indicator and, if out of spec, the fix is an engine‑out job with the sump and crank removed to replace the main bearing set (the thrust faces are part of that set). It’s not a DIY driveway swap.

When might a mechanic suspect thrust bearing distress? Look for a combination of:

• Fine metallic in the oil filter or sump during an oil change
• Noticeable crank pulley or flywheel fore‑aft movement
• Harsh idle knock that changes as the engine is gently loaded in gear (for DCT, with the brakes held)
• Measured end float outside workshop manual limits

If replacement is required, best practice is to renew all main bearings, inspect the crank thrust faces, check clearances with plastigauge, and verify oil pressure on first start. For DCT models, don’t chase a “clutch thrust bearing” noise—release bearings are internal to the clutch module and are serviced as an assembly if ever required. Sticking to timely oil services and not lugging the engine under heavy load at very low revs are the simplest ways to keep the thrust bearing content over hundreds of thousands of kilometres.

Popular questions

Does the 2021 Haval H6 have a thrust bearing?
Yes. The H6’s petrol engines use an integrated crankshaft thrust bearing within the main bearing set to control end float. There isn’t a separate manual-gearbox throwout bearing on DCT or hybrid models, any clutch release hardware is internal to the module.

What symptoms point to thrust bearing wear on a Haval H6?
Tell‑tales include excessive crankshaft end float when measured, a harsh axial knock at idle that changes with slight load, and fine metallic in the oil. These are workshop‑level checks, it usually isn’t obvious to drivers until wear is advanced.

Is thrust bearing replacement part of normal servicing?
No. It’s not a scheduled item. Replacement only happens during engine repair if end float is out of spec or bearing damage is confirmed. Prevention is mostly about good oil, correct intervals, and avoiding abuse when the engine is cold.
