Product Features

• Structure: Precision-machined from high-strength alloy steel with a hardened gear surface, and an integrated precision bronze bushing for smooth rotation.

• Performance: Transmits torque in the timing gear train, maintaining precise valve timing. The hardened teeth resist wear and fatigue, while the bronze bushing ensures low-friction rotation even under high loads.

• Design: Factory-calibrated for exact tooth meshing and timing accuracy, with a direct-fit mounting bore that aligns perfectly with the cylinder block.

Core Function

• Transfers rotational power between the crankshaft and camshaft gears, ensuring the engine’s valves open and close at the precise moment for optimal combustion.

• Maintains stable timing across all engine speeds, preventing valve-piston interference and ensuring smooth, efficient engine operation.

• The robust construction ensures long service life and reliable performance in heavy-duty operating conditions.

Frequently Asked Questions About the 200-04505-5093 Middle Gear-Cylinder Block

What is the function of the middle gear-cylinder block in a SINOTRUK engine?

The middle gear-cylinder block acts as an intermediate timing gear housed within the engine block assembly. It transfers rotational force between the crankshaft gear and camshaft gear, maintaining precise valve timing and fuel injection synchronization. Without proper gear mesh, engine performance degrades and component wear accelerates.

How do I verify that 200-04505-5093 fits my specific SINOTRUK model?

Cross-reference the part number 200-04505-5093 against your engine’s parts catalog or the number stamped on your existing middle gear-cylinder block. If you are unsure, send us your VIN or engine nameplate photo and our technical team will confirm compatibility within 24 hours.

What causes premature wear on the middle gear-cylinder block?

Common failure causes include contaminated engine oil carrying abrasive particles, improper gear backlash during previous installation, and overheating due to coolant system failures. Using OEM-spec parts and following recommended oil change intervals significantly extends gear life.

Is this part identical to the original SINOTRUK factory component?

This part is manufactured to OEM-equivalent specifications, matching the original in material composition, dimensional tolerances, heat treatment, and surface finish. It functions as a direct drop-in replacement without requiring any machining or adaptation.

How should I store this part before installation?

Keep the middle gear-cylinder block in its original packaging in a dry, temperature-controlled environment. The phosphate coating provides short-term corrosion protection, but prolonged exposure to humidity can compromise the surface. Install within 12 months of receipt for best results.
