description

Part number: 800165826
Part name: valve system parts
Unit name: power system
Applicable Models: XCMG XP203 pneumatic-tyred roller

800165826 Valve System Parts include intake valves, exhaust valves, valve seats, valve guides, valve springs, retainers, locks, oil seals and related small parts. Made of heat‑resistant alloy steel and high‑strength materials with precision grinding and heat treatment, they have good sealing, high wear resistance, stable elasticity and long service life. They are installed on the cylinder head to complete accurate gas exchange according to engine operating cycle. Suitable for long‑term high‑temperature, high‑frequency movement and heavy‑load working conditions, they effectively solve problems such as air leakage, insufficient cylinder pressure, difficult starting, black smoke, abnormal noise and power reduction caused by wear, deformation, fatigue or poor sealing of valve parts, ensuring stable and efficient engine operation.

advantages

  • High temperature & wear resistance: Special alloy valves and seats stably work under high temperature without easy wear or deformation.
  • Excellent sealing performance: Precision grinding ensures tight fitting, effectively preventing cylinder air leakage.
  • Stable elasticity & fatigue resistance: High‑performance valve springs ensure reliable closing and long service life.
  • Good oil sealing: Special valve oil seals avoid oil entering the combustion chamber and reduce carbon deposits.
  • Original standard matching: Strictly consistent with OEM size, direct replacement with perfect fit.

maintenance & replacement tips

  • Check valves, seats and springs regularly for wear, deformation, fatigue or breakage; replace damaged parts in time.
  • If engine experiences insufficient cylinder pressure, misfire, black smoke or abnormal noise, inspect valve system parts for leakage or failure.
  • During replacement, grind valves and seats if necessary to ensure good sealing surface contact.
  • Replace valve oil seals uniformly to prevent oil burning and carbon deposit problems.
  • After installation, check valve clearance and running condition; confirm no air leakage, abnormal noise or unstable idle speed.
