What Is the CORTECO 49496335 Shaft Seal?

CORTECO 49496335 is a specialized radial shaft seal for differential and driveshaft applications, manufactured from ACM (Polyacrylate Rubber). Its dimensions are 44x60/67.2x13 mm, meaning a 44 mm inner diameter, stepped outer diameters of 60 mm and 67.2 mm, and a height of 13 mm. The seal corresponds to Ford OE numbers 1490305 and 8C1R3K169AA and is used in selected Ford Transit and Transit Custom drivetrain applications.

Ford OE Reference Numbers

The most important OE references for CORTECO 49496335 are:

FORD 1490305

FORD 8C1R3K169AA

FORD 8C1R-3K169-AA

These OE numbers are directly cross-referenced with CORTECO 49496335.

Ford Transit Applications

The CORTECO 49496335 shaft seal is catalogued for selected versions of:

• Ford Transit
• Ford Transit Custom V362
• Ford Transit V363
• Ford Transit Tourneo
• Selected VMT6 6-speed manual transmission applications

Depending on the vehicle configuration, it is used as a differential or driveshaft seal. Compatibility should always be verified using the OE number and vehicle specification rather than vehicle model alone.

Why Is the Correct Size 44x60/67.2x13 mm?

This CORTECO seal has a more complex geometry than a conventional radial shaft seal.

The complete dimensions are:

Inner diameter: 44 mm

First outer diameter: 60 mm

Second outer diameter: 67.2 mm

Height: 13 mm

Therefore, 44x67.2x13 mm is only a simplified dimensional description. For accurate technical identification and replacement searches, 44x60/67.2x13 mm is the more precise specification.

ACM Polyacrylate Rubber

The 49496335 is manufactured from ACM, or Polyacrylate Rubber.

ACM is commonly selected for automotive sealing applications requiring resistance to lubricating oils and elevated operating temperatures.

Typical ACM applications include:

• Transmissions
• Differentials
• Drivetrain components
• Driveshaft sealing
• Gear oil applications
• Automotive power transmission systems

The actual suitability of the elastomer should always be checked against the lubricant, temperature and operating conditions of the specific application.

Differential and Driveshaft Sealing

The purpose of the CORTECO 49496335 is to maintain sealing around the rotating shaft while helping retain lubricant within the drivetrain assembly.

A correctly installed shaft seal helps reduce:

• Gear oil leakage
• Loss of lubricant
• Contamination around the drivetrain
• Ingress of external contaminants
• Premature wear associated with lubricant loss

Why OE Number Verification Is Important

Automotive shaft seals should not be selected solely by their dimensions.

Even when another seal has a similar inside and outside diameter, differences in:

• Lip geometry
• Housing design
• Elastomer material
• Installation depth
• Auxiliary sealing features

may make it unsuitable.

For CORTECO 49496335, the most important identification references are Ford 1490305 and Ford 8C1R3K169AA.

Installation Recommendations

Before installing the new seal:

• Inspect the shaft sealing surface
• Clean the seal housing
• Check for corrosion or burrs
• Verify the OE reference
• Confirm the installation direction
• Protect the sealing lip from sharp edges
• Use an appropriate installation tool
• Press the seal evenly into its seat

Avoid applying impact directly to the sealing lip or deforming the outer structure during installation.

Frequently Asked Questions (FAQ)

What are the dimensions of CORTECO 49496335?
The complete dimensions are 44x60/67.2x13 mm: 44 mm inner diameter, 60 mm first outer diameter, 67.2 mm second outer diameter and 13 mm height.

What material is CORTECO 49496335 made from?
It is manufactured from ACM (Polyacrylate Rubber).

Does CORTECO 49496335 replace Ford 1490305?
Yes. Ford 1490305 is listed as an OE reference for this CORTECO seal.

Is Ford 8C1R3K169AA equivalent to CORTECO 49496335?
Yes. 8C1R3K169AA, also written 8C1R-3K169-AA, is an OE reference associated with CORTECO 49496335.

Is this seal used in Ford Transit vehicles?
Yes. It is catalogued for multiple Ford Transit, Transit Custom and related drivetrain applications. Exact fitment depends on the vehicle and transmission configuration.

Frequently Asked Questions from Mechanics and Engineers

Is the size simply 44x67.2x13 mm?
That is a simplified description. The complete dimensional specification is 44x60/67.2x13 mm because the seal has two specified outer diameters.

Can I replace it with a standard NBR oil seal of similar dimensions?
A replacement should not be selected solely by dimensions. The original seal uses ACM and has a specific stepped geometry, so the OE reference and construction should also be matched.

Is CORTECO 49496335 a differential seal?
Yes. It is catalogued as a differential shaft seal, while some catalogues also describe its function in relation to the driveshaft or axle shaft.

What is the best way to confirm compatibility?
Compare the vehicle's required OE number with Ford 1490305 or 8C1R3K169AA, then verify the dimensions and installation location.

What does ACM mean?
ACM stands for polyacrylate rubber, an elastomer widely used in automotive oil sealing applications where resistance to lubricants and elevated temperatures is required.
