Common causes of failure include:
- High mileage gearbox wear.
- Aggressive shifting techniques.
- Repeated poor gear engagement.
- Worn synchroniser rings.
- Transmission oil contamination.
- Excessive gearbox loading.
- Age-related wear and fatigue.
- Incorrect gearbox setup during previous repairs.
First gear dog teeth are particularly susceptible to wear because they experience frequent engagement from stationary starts and low-speed driving.
When Should 1st Gear Dog Teeth Be Replaced?
Dog teeth should always be carefully inspected whenever the
gearbox is dismantled. Replacement is recommended if you notice:
- Difficulty engaging 1st gear.
- Gear crunching during shifts.
- Jumping out of gear.

What Does the Flywheel Ring Gear Do?
The flywheel ring gear is mounted around the outer edge of the flywheel and serves as the engagement point for the starter motor pinion gear.
When the ignition is activated, the starter motor extends its pinion gear into the teeth of the flywheel ring gear. The starter then rotates the flywheel, which in turn rotates the crankshaft and starts the engine.
The flywheel ring gear performs several essential functions:
- Transfers rotational force from the starter motor to the engine.
- Allows the engine to crank during start-up.
- Provides precise engagement with the starter pinion gear.
- Supports smooth and reliable engine starting.
- Helps prevent starter slippage and gear damage.
On the turbocharged Porsche 930, where higher compression and engine loads place greater demands on the starting system, proper ring gear condition is especially important.
Why Do Flywheel Ring Gears Fail?
Although manufactured from hardened steel, flywheel ring gears endure repeated mechanical stress throughout their service life. Every engine start places load on the gear teeth, eventually leading to wear and damage.
Common causes of flywheel ring gear failure include:
- Tooth wear from repeated starter engagement.
- Chipped, cracked or broken gear teeth.
- Worn starter motor pinion gears.
- Starter motor misalignment.
- Corrosion caused by moisture exposure.
- Excessive heat from clutch or flywheel issues.
- High mileage and decades of use.
Many Porsche 930 models have now accumulated decades of service, making flywheel and starter system inspections increasingly important during restoration and maintenance work.
When Should the Flywheel Ring Gear Be Replaced?
The ring gear should be inspected whenever the clutch,
transmission or engine assembly is removed. Replacement is recommended if any
of the following are found:
- Worn or rounded gear teeth.
- Broken or chipped teeth.
- Starter grinding noises.
- Intermittent starter engagement.
- Difficulty cranking the engine.
- Visible corrosion or physical damage.
- Excessive wear concentrated in specific areas of the gear.
Because replacement requires flywheel removal, many specialists recommend fitting a new ring gear during clutch replacement or major drivetrain refurbishment when access is readily available.

Manufactured to OE specifications, this replacement ring gear delivers the correct tooth profile, fitment and durability required for classic air-cooled Porsche applications. Whether you're rebuilding an engine, replacing a worn flywheel component or restoring a classic 911, fitting a new flywheel ring gear helps ensure smooth starter operation and long-term reliability.
What Does the Flywheel Ring Gear Do?
The flywheel ring gear is a hardened steel gear mounted around the outer circumference of the flywheel. Its primary purpose is to engage with the starter motor pinion gear during engine start-up.
When the ignition key is turned, the starter motor extends its pinion gear into the teeth of the flywheel ring gear. The starter then rotates the flywheel, turning the engine over until combustion begins and the engine starts.
The flywheel ring gear plays a vital role by:
- Providing a durable engagement surface for the starter motor.
- Allowing the engine to crank during start-up.
- Ensuring smooth and reliable starter operation.
- Transferring rotational force from the starter motor to the crankshaft.
- Supporting consistent engine starting performance.
Without a properly functioning ring gear, starter engagement can become unreliable or impossible.
Why Do Flywheel Ring Gears Fail?
Although manufactured from hardened steel, flywheel ring gears experience repeated mechanical loading every time the vehicle is started. Over decades of service, wear and damage can occur.
Common causes of failure include:
- Tooth wear caused by repeated starter engagement.
- Damaged or chipped gear teeth.
- Starter motor misalignment.
- Worn starter pinion gears damaging the ring gear.
- Excessive heat generated during clutch or flywheel issues.
- Corrosion caused by moisture contamination.
- General wear associated with high mileage and age.
On classic Porsche 911 models, decades of repeated engine starts can eventually lead to worn sections of the ring gear, particularly in the areas where the engine most commonly stops after shutdown.
When Should the Flywheel Ring Gear Be Replaced?
The flywheel ring gear should be inspected whenever the
engine, clutch or flywheel assembly is removed. Replacement is recommended if
you observe:
Chipped,
broken or heavily worn teeth.
Replacing a worn ring gear while the transmission or engine is already removed can prevent future starting problems and reduce labour costs.

Fits:
Porsche 911 1974 - 1986 (915 Gearbox)
Diagram ref no 37
The synchro / brake band is part of the gearbox synchroniser system, helping to slow or control rotation of a gear or hub during shift transitions, promoting smooth engagement and preventing clash. It works in concert with the synchroniser rings, hubs, sleeves, and gearsets to align speeds of rotating parts before lock-in. Proper material, friction surface, and design are critical — the band must provide the correct friction characteristics without binding or excessive wear.
• Installation: Direct OE replacement — recommended during gearbox overhaul
• Position / Location: This part is located inside the manual transmission, within the synchroniser assembly — the mechanism that equalizes gear and shaft speeds for smooth engagement. It wraps around the synchroniser hub and works with the synchro ring and dog teeth gear to provide friction and control during shifting.
• Benefits: Restores synchroniser performance, eliminates grinding, reduces wear on gears and rings
Why replacement matters:
• With use, the original band’s friction surfaces can glaze, wear, or lose consistency, impairing its ability to slow or stabilise gear/hub motion during shifting.
• A worn or ineffective brake / synchro band can result in grinding gears, missed shifts, or gear clash, especially under load or during aggressive shifting.
• Installing a high-quality replacement restores proper friction behaviour, enabling smooth engagement, reducing wear on adjacent synchroniser elements, and extending transmission life.
• Because the transmission internals are sensitive to mismatches or degraded components, having a reliable replacement band ensures system integrity and maintains the “feel” of the gearbox.
