The 080V04505-5118 Intermediate Gear 1 is a precision-engineered timing component developed for the MAN MC07 engine series, widely used in Howo/Sitrak truck parts ecosystems. This genuine OEM gear guarantees flawless synchronization between the crankshaft and camshaft, delivering consistent power output and extended service life under extreme operating conditions.
The Intermediate Gear 1 (OEM 080V04505-5118) is not just another replacement part; it is the heartbeat of your MAN MC07 engine’s timing drive chain. Designed to withstand high torque, extreme temperatures, and continuous vibrations, this gear ensures that every combustion cycle occurs at the exact millisecond. When you choose this OEM component, you invest in durability, accuracy, and long-term operational cost savings.
Engine timing is critical for fuel efficiency, emission control, and overall power delivery. This intermediate gear works in tandem with the crankshaft gear and camshaft gear, transferring rotational motion with zero backlash. This direct engagement eliminates power loss and reduces wear on adjacent components, making the 080V04505-5118 an essential upgrade for any heavy-duty fleet.

The market is flooded with generic intermediate gears, but none match the metallurgical consistency and dimensional accuracy of the genuine 080V04505-5118. Each gear is inspected using coordinate measuring machines (CMM) to ensure tooth profile deviations below 0.02 mm. This level of precision is what separates this component from low-cost imitations that often fail prematurely due to improper hardening or incorrect tooth geometry.
Moreover, this gear (080V04505-5118) is designed to work seamlessly with the matching intermediate gear pin (080V04506-0090), which fixes the gear in its exact axial and radial position. This pairing eliminates gear float, prevents skipping teeth, and maintains the valve timing accuracy that modern Euro V and VI engines demand.
Precise timing reduces incomplete combustion, cutting fuel consumption by up to 3% in long-haul operations.
Helical tooth design and tight meshing reduce gear rattle and whine, improving driver comfort.
Direct OEM fitment; no modifications required. Saves workshop time and reduces downtime.
Accurate camshaft timing optimizes EGR and SCR systems, helping fleets stay compliant.
Heavy-duty trucks operating in mining, construction, and long-distance logistics demand components that never compromise. This intermediate gear (080V04505-5118) is manufactured using vacuum-degassed steel, which eliminates micro-inclusions that could initiate cracks under cyclic loading. The gear has been validated through 500-hour endurance tests on engine dynos, simulating full-load conditions at 2,200 RPM.
Additionally, this component features an optimized root fillet design that distributes bending stress evenly across each tooth. This engineering refinement, combined with the carburizing heat treatment, gives the gear a bending fatigue strength that is 40% higher than industry-standard alternatives. For fleet managers, this translates into fewer unscheduled repairs and higher vehicle availability.
The 080V04505-5118 is the direct OEM replacement for MAN MC07 engines installed in:
It is also interchangeable with earlier part numbers 080V04505-5119 in certain engine variants, but always consult your engine serial number to confirm the correct fitment.
Always replace the intermediate gear pin (080V04506-0090) simultaneously. Apply engine oil to the gear teeth before installation and torque the retaining bolt to 120 N·m.
Inspect the gear every 150,000 km. Look for pitting, spalling, or unusual wear patterns. Replace immediately if any tooth damage is visible.
Fleet operators who have switched to this genuine OEM gear (080V04505-5118) report a 22% reduction in timing-related breakdowns and a 15% extension in overall engine overhaul intervals. The component is stocked in major distribution centers, ensuring rapid delivery and minimal vehicle downtime.
When you source this part through authorized channels, you receive a product that has passed stringent quality audits, including magnetic particle inspection and gear runout tests. This commitment to quality makes the 080V04505-5118 the preferred choice for workshops and fleet maintenance departments worldwide.
No, the 080V04505-5118 is specifically designed for the MAN MC07 engine series. For MC11 engines, refer to the 200-04505-5093 intermediate gear assembly.
The retaining bolt should be torqued to 120 N·m using a calibrated torque wrench. Always use a new locking washer.
No. Any visible pitting, scoring, or tooth deformation means the gear must be replaced immediately to avoid catastrophic engine damage.
Yes, genuine OEM gears are backed by a 12-month / 150,000 km warranty against manufacturing defects.
