What This Product Does

This retaining ring locates the flange assembly axially, limiting movement along the shaft. It is retaining hardware rather than an oil seal, and should not be confused with the complete flange.

Functions

  • Restrains axial displacement of the retained flange component.
  • Supplies replacement retaining hardware during applicable transmission repairs.

Technical Details

  • Brand: OE Match; Porsche reference: 9P1311152.
  • Snap ring specification: D36x2,6, also recorded as D36x2.6mm.
  • Assembly quantity: two rings in each supplied diagram; individual sale quantity is one.

Symptoms of Fault

Movement at the flange, take-up knocks, load-related vibration or nearby lubricant leakage justify an assembly inspection, not an automatic ring diagnosis. Check joints, mounts, flange splines and seals before attributing these symptoms to retaining hardware.


Why Replacement Matters

Renew a retaining ring if inspection reveals deformation or damage that prevents correct seating. Examine its groove and neighbouring components during dismantling, and use the installation method specified for the transmission. A replacement ring cannot compensate for groove damage, flange wear or a defective seal.

FAQs

  • Does the flange come with this ring?
    No. The component identified by 9P1311152 is the retaining ring, not a flange assembly.
  • Can it fit a manual gearbox?
    Selected manual applications appear in the supplied diagrams alongside PDK applications. Verify the transmission code and reference before installation.
  • How many should I order?
    Sold each - 2 required per car. Confirm how many are needed for the planned repair.
  • Will fitting it stop an oil leak?
    The ring provides retention, not sealing. Investigate the leak source and examine the adjacent oil seal and flange surfaces.

What Does It Do?

The input shaft oil seal creates an oil-tight barrier between the rotating gearbox shaft and the surrounding transmission housing.

It helps retain gearbox oil, preventing leakage and ensuring internal transmission components receive the lubrication required for reliable operation.

Why Is It Important?

The Porsche PDK gearbox relies on the correct transmission fluid level for lubrication, cooling and operation.

A leaking shaft seal can result in:

  • Transmission fluid loss
  • Oil contamination around the gearbox
  • Reduced lubrication
  • Increased internal component wear
  • Potential gearbox damage if fluid loss continues

Replacing a defective seal helps restore the gearbox's sealing integrity.

Why Does It Fail?

Over time, the oil seal can deteriorate due to:

  • Ageing and hardening of the sealing material
  • Repeated heat cycles
  • Wear against the rotating shaft
  • Contaminated transmission fluid
  • Incorrect installation
  • Damage to the shaft sealing surface

These conditions can reduce sealing effectiveness and allow transmission fluid to escape.

When Should It Be Replaced?

Replace the oil seal if:

  • Transmission fluid is leaking from the shaft sealing area
  • The seal is cracked, hardened or damaged
  • Oil contamination is visible around the gearbox housing
  • The seal is disturbed during gearbox or clutch repairs
  • A transmission rebuild requires replacement sealing components

Always confirm the source of a leak before replacing the seal.

Checks & Installation

Inspect the shaft sealing surface and surrounding gearbox housing for damage.

Remove the old seal carefully and install the replacement squarely to the specified depth using suitable installation tools.

Follow Porsche workshop procedures and check the correct transmission fluid level after repairs.

Application:
• Manual transmission input shaft oil seal
• Cross-referenced with superseded part number: 99911332640

The input shaft seal sits around the input/main shaft where it enters the transmission case. Its job is to keep transmission fluid from leaking out and to prevent contamination from entering the gearbox. By maintaining a secure seal around the rotating shaft, this component helps preserve optimal lubrication, reduce wear, and support smooth gear operation.

In a manual transmission, the input shaft takes power from the clutch and delivers it into the gearbox. The seal must endure rotation, pressure changes, heat, and exposure to transmission fluid, forming a durable barrier that keeps oil inside while preventing dirt and debris from entering. A properly functioning input shaft seal is crucial for transmission longevity and performance.

Over time and mileage, seals can harden, crack, or lose elasticity due to heat, oil exposure, and mechanical wear. A failed input shaft seal can lead to:
• Transmission fluid leaks
• Low fluid levels
• Increased gearbox noise
• Premature wear on gears and bearings
• Potential drivetrain damage

Replacing worn or leaking seals restores proper fluid containment and protects the integrity of the transmission system, preserving performance and reducing the risk of costly repairs.

Replace the input shaft seal if you notice:
• Visible transmission fluid leaks at the bellhousing area
• Low transmission fluid levels
• Gearbox whine or unusual noises
• Transmission slipping or crunching in gear shifts
• After transmission removal or overhaul
