Intermediate shaft gear. Porsche 356C / 912  ❭  PCG10510302

Intermediate Shaft Gear, That Is +.001 Over.
Restore correct intermediate shaft drive operation and gear engagement during an engine rebuild with this OE Match Intermediate Shaft Gear, +.001 Oversize, reference PCG10510302/1. Designed for compatible Porsche engine applications, this precision replacement gear is intended for situations where a +.001 oversize specification is required to achieve the correct gear fit and operating relationship within the engine.

Fits: Porsche 356C / 912

The intermediate shaft is an important part of the engine's internal drive system. Depending on the engine design, it transfers rotational movement from the crankshaft to associated components and helps maintain correct mechanical timing and drive operation. The intermediate shaft gear must mesh accurately with its mating gear to provide smooth, consistent power transfer without excessive backlash, noise, or mechanical loading.  

What This Product Does:

• Transfers rotational drive through the engine's intermediate shaft system.
• Helps maintain correct operation of associated engine drive components.
• Meshes with its corresponding gear to provide smooth mechanical power transfer.
• Helps maintain the specified gear engagement and backlash.
• Supports accurate and consistent intermediate shaft rotation.
• Features a +.001 oversize specification for applications requiring this particular size.
• Helps reduce excessive gear movement when correctly selected and installed.
• Replaces a worn, damaged, incorrectly sized, or unsuitable intermediate shaft gear.
• Provides an OE Match solution for compatible Porsche engine rebuilds.

Symptoms Of Wear Or Failure:

• Abnormal whining or gear noise from inside the engine.
• Rattling or mechanical noise associated with the intermediate shaft drive.
• Excessive gear backlash discovered during an engine rebuild.
• Visible wear on the gear teeth.
• Chipped, cracked, or damaged gear teeth.
• Pitting or abnormal wear across the gear contact surfaces.
• Uneven gear tooth contact patterns.
• Excessive play within the intermediate shaft drive.
• Metallic particles or gear debris in the engine oil.
• Abnormal wear of the mating gear.
• Incorrect gear clearance identified during engine assembly.
• Existing gear dimensions outside the required specification.

Why Replacement Matters:

• The intermediate shaft gear operates as part of a precision mechanical drive system. Correct tooth engagement and gear clearance are essential for smooth operation, controlled mechanical loads, and long component life.
• A worn or incorrectly sized gear can create excessive backlash, uneven tooth loading, vibration, and abnormal mechanical noise. Continued operation may accelerate wear of both the intermediate shaft gear and its mating component, potentially introducing metallic debris into the engine lubrication system.
• Insufficient clearance can be equally problematic. A gear that is too tight may generate excessive friction and heat, increase loading on the shaft and bearings, and cause accelerated gear wear or mechanical damage. This is why selecting the correct size is particularly important with an oversize component.
• The +.001 specification of this gear should therefore be treated as a precision engine-building dimension. It must be confirmed as correct for the individual engine rather than selected solely because the original gear appears worn.
• Replacing a worn or unsuitable component with the correctly specified OE Match Intermediate Shaft Gear +.001 Oversize PCG10510302/1 helps restore proper gear engagement, controlled backlash, smooth intermediate shaft operation, and dependable engine performance.
