Constructed from durable oil-resistant materials, the seal is designed to withstand continuous shaft rotation, temperature fluctuations and long-term exposure to transmission oil. It is an essential service item during gearbox repairs, rebuilds and preventative maintenance.
What This Product Does:
- Prevents gearbox oil from leaking around the mainshaft.
- Maintains proper lubrication within the transmission.
- Protects gearbox components from oil loss.
- Prevents dirt, moisture and contaminants from entering the gearbox.
- Supports reliable transmission performance and longevity.
- Helps maintain correct gearbox oil levels.
Symptoms Of Wear Or Failure:
- Gearbox oil leaks beneath the vehicle.
- Oil residue around the transmission housing or shaft area.
- Gradual loss of gearbox oil.
- Difficulty maintaining correct transmission fluid levels.
- Contamination of surrounding components with oil.
- Increased transmission noise caused by reduced lubrication.
- Premature wear of gearbox bearings and internal components.
- Burning oil smells if leaking oil contacts hot surfaces.
Why Replacement Matters:
- Mainshaft oil seals are subjected to constant shaft rotation, vibration, heat and prolonged exposure to transmission oil. Over time, the sealing lip can harden, wear or lose elasticity, reducing its ability to maintain an effective seal.
- A leaking oil seal can allow gearbox lubricant to escape, potentially reducing lubrication to critical internal components. If left unresolved, low oil levels can accelerate wear of gears, bearings and synchronisers, leading to costly transmission repairs or rebuilds.
- Replacing a worn mainshaft oil seal helps preserve correct gearbox lubrication, prevents oil leaks and protects internal transmission components from premature wear. An OE Match replacement restores the integrity of the gearbox sealing system and helps ensure reliable long-term transmission performance.

Dog Teeth 1st Gear.
The OE Match 1st Gear Dog Teeth is a high-quality replacement gearbox component designed for Porsche manual transmissions. Manufactured to OE specifications for fit, precision and durability, this component forms a critical part of the gear engagement mechanism, allowing smooth and secure engagement of first gear during operation.
Fits:
Diagram Ref No 43
The dog teeth ring is fitted to the gear assembly and works in conjunction with the synchroniser hub, synchroniser ring and selector sleeve. It provides the engagement points that lock the selected gear to the transmission shaft, ensuring efficient transfer of engine power through the gearbox. Precision machining is essential for smooth shifting performance and long transmission service life.

It provides the engagement points that lock the selected gear to the transmission shaft, ensuring efficient transfer of engine power through the gearbox. Precision machining is essential for smooth shifting performance and long transmission service life.
What This Product Does:
- Provides the engagement surface for first gear selection.
- Works with the synchroniser assembly to enable smooth gear changes.
- Locks first gear to the transmission shaft when selected.
- Ensures efficient transfer of engine power through the gearbox.
- Supports accurate and reliable gear engagement.
- Helps minimise transmission wear during shifting.
- Contributes to smooth manual gearbox operation.
Symptoms Of Wear Or Failure:
- Difficulty engaging first gear.
- Gear crunching or grinding during gear selection.
- First gear jumping out of engagement under load.
- Increased resistance when shifting into first gear.
- Poor shift quality or inconsistent engagement.
- Excessive transmission noise during gear changes.
- Visible wear, rounding or chipping of the dog teeth during inspection.
- Premature wear of related synchroniser components.
Why Replacement Matters:
- Dog teeth are subjected to repeated engagement loads every time a gear is selected. Over time, the engagement surfaces can become worn, rounded or damaged, particularly in high-mileage transmissions or vehicles subjected to aggressive shifting. As wear progresses, gear engagement becomes increasingly difficult and less precise.
- A worn dog teeth ring can compromise synchroniser performance and may eventually prevent proper engagement of first gear. Continued operation with worn components can accelerate wear of synchroniser hubs, selector sleeves and other transmission parts, leading to more extensive and costly gearbox repairs.
- Replacing worn first gear dog teeth restores precise gear engagement, improves shift quality and helps protect the transmission from further internal wear. An OE Match replacement provides factory-style fitment, accurate machining and long-term durability, ensuring reliable gearbox operation and preserving the driving experience expected from your Porsche.

Transmission gearbox teeth. Dog teeth 2nd gear.
G915 up to 1975 1st gear / G915 1976>> 2nd. gear
Fits:
Porsche 911 1974-86 (915 Gearbox)
Diagram Ref no 35.
A dog-teeth gear (or synchronizer-gear hub / 1st-2nd gear dog gear) used inside the 915 gearbox. This gear section engages with corresponding hub or clutch-dog components to allow shifting between gears - in particular 1st and/or 2nd gear depending on the configuration.
Gears inside classic 915 transmissions - especially dog / synchronizer-gears - are subject to wear over time: tooth heads can round off, suffer chip-out, or distort under load; synchronizer engagement surfaces may wear and lose precision. This can cause:
• Gear-slip or missed shifts
• Grinding or clash during shifting
• Torque transmission loss or vibration under load
• Accelerated wear of other transmission internals.
Replacing worn gears with a precisely machined, correctly hardened OE-match replacement restores gear-mesh integrity, retains gearbox performance, and helps avoid costly gearbox failure.
When to Replace.
Consider fitting this gear if:
• You hear grinding, clash, or crunching during shifting - especially into 1st or 2nd gear
• Gearbox inspection reveals worn, rounded, chipped, or damaged dog-teeth or synchronizer surfaces
• You are performing a full gearbox rebuild or overhaul
• The gearbox has high mileage or signs of internal wear
• You want to restore factory-spec shifting performance and reliability
