Input Shaft Oil Seal 1096253230 For ISUZU CYZ51 6WF1 10PE1 1-09625323-0

Precision-engineered input shaft oil seal prevents transmission fluid leakage at the input shaft, protecting the gearbox from contamination and ensuring reliable drivetrain performance for ISUZU heavy-duty trucks.

The Input Shaft Oil Seal (OEM Numbers: 1096253230 / 1-09625323-0) is a premium-quality, direct replacement sealing component designed specifically for ISUZU CYZ51 series heavy-duty trucks equipped with 6WF1 and 10PE1 diesel engines. This precision-engineered oil seal is a critical component of the transmission input shaft assembly, responsible for preventing transmission fluid leakage where the input shaft enters the gearbox housing.

• OE Quality: Manufactured to strict ISUZU dimensional and material specifications for perfect fit and function
• Precision Sealing Lip: Engineered to maintain consistent contact pressure for reliable fluid retention
• Garter Spring Design: Ensures lip tension remains constant, compensating for minor wear and temperature fluctuations
• Durable Material: High-grade synthetic rubber provides excellent resistance to transmission fluid, heat, aging, and weathering
• Rust-Protected Casing: Metal casing is coated or treated to resist corrosion
• Contaminant Exclusion: Prevents dust and debris from entering the transmission through the input shaft opening
• Fluid Retention: Prevents transmission fluid leakage, avoiding low fluid levels and potential gear/bearing damage
• Protects Transmission: Proper sealing ensures reliable transmission operation and extended service life
• Direct Replacement: Simple installation during transmission service
• Cost-Effective Maintenance: Prevents expensive transmission repairs

Professional installation required. Proper procedure is critical for leak-free performance:

1. Raise and secure the vehicle - Safely lift the vehicle and support on jack stands
2. Remove the transmission - Remove the transmission assembly for access to the input shaft
3. Remove the old seal - Carefully remove the old input shaft seal using a seal puller, avoiding damage to the housing
4. Inspect the input shaft sealing surface - Check for scoring, pitting, or wear; polish or replace as needed
5. Clean the seal bore - Thoroughly clean the housing bore and remove all debris
6. Lubricate the new seal lip - Apply a thin coat of clean transmission fluid or assembly lube to the sealing lip
7. Position the new seal - Align the seal squarely with the housing bore (lip facing inward toward the transmission)
8. Install the seal - Use a proper seal installer tool to press the seal evenly into the bore until fully seated at the correct depth
9. Inspect installation - Verify seal is squarely seated and at the correct depth
10. Reinstall the transmission - Reinstall the transmission assembly and all connected components
11. Refill transmission fluid - Refill the transmission with the correct type and amount of fluid
12. Check for leaks - Start the engine and check for fluid leakage at the input shaft area
13. Road test - Test drive the vehicle and re-inspect for leaks after the test
