Acura 91216-PG1-005 Manual Trans Input Shaft Seal

Product Overview

The Acura 91216-PG1-005 Manual Trans Input Shaft Seal is a genuine Acura replacement part designed to maintain the integrity of your vehicle's manual transmission system. This seal prevents the leakage of transmission fluid from around the input shaft, ensuring proper lubrication and operation of internal components.

Installation Guidelines

Proper installation is crucial for the effective performance and longevity of the input shaft seal. It is highly recommended that installation be performed by a qualified automotive technician using appropriate tools and procedures.

Preparation: Ensure the transmission housing and input shaft are thoroughly cleaned and free of old seal material, debris, or contaminants. Any surface imperfections can compromise the new seal's integrity.
Lubrication: Lightly lubricate the inner lip of the new seal with clean transmission fluid before installation. This aids in smooth installation and prevents damage to the seal.
Installation Tool: Use a seal driver tool of the correct size to press the new seal evenly into its bore. Avoid using hammers directly on the seal, as this can deform it or cause damage.
Alignment: Ensure the seal is seated squarely and fully into the bore. Uneven installation can lead to premature failure and leaks.
Fluid Refill: After installation, refill the transmission with the manufacturer-specified fluid to the correct level.

Refer to your vehicle's specific service manual for detailed, model-specific installation instructions and torque specifications.

Function and Operation

The input shaft seal's primary function is to create a tight barrier between the transmission's internal components and the external environment. It prevents transmission fluid from leaking out where the input shaft enters the transmission case. This ensures that the transmission's gears and bearings remain properly lubricated, which is essential for smooth shifting, efficient power transfer, and preventing premature wear of critical components.

Maintenance and Inspection

While the input shaft seal itself is a passive component, its integrity is vital for transmission health. Regular maintenance involves monitoring for signs of fluid leaks and ensuring proper transmission fluid levels.

Fluid Level Checks: Periodically check your transmission fluid level according to your vehicle manufacturer's recommendations. Low fluid levels can indicate a leak, potentially from the input shaft seal.
Leak Detection: Inspect the area around the transmission, particularly where the input shaft enters the case, for any signs of fluid seepage or drips. A clean garage floor or driveway can help identify new leaks.
Fluid Quality: Ensure the transmission fluid is clean and free of burnt odors or excessive debris, as contaminated fluid can accelerate seal wear.

Address any detected leaks promptly to prevent more significant transmission damage.

Troubleshooting

The primary issue associated with a failing input shaft seal is fluid leakage. If you observe any of the following, the input shaft seal may require inspection and replacement:

Visible Fluid Leaks: Puddles or drips of transmission fluid (often reddish or brownish) under the front or middle of the vehicle, particularly near the transmission bell housing.
Low Transmission Fluid Level: Consistent or rapid drops in transmission fluid level without an obvious external cause.
Clutch Slippage (Manual Transmissions): In manual transmissions, a severe input shaft seal leak can contaminate the clutch disc, leading to clutch slippage or difficulty engaging gears.

If you suspect a seal failure, it is advisable to have the vehicle inspected by a professional technician to confirm the diagnosis and perform the necessary repair.
