Technical data - CORTECO 01034649

What does CORTECO 01034649 FPM B1BASLSFRDX46 mean?

The complete product identification is:

CORTECO 01034649 FPM B1BASLSFRDX46 65x95x11/16 mm

CORTECO - manufacturer of the sealing component.

01034649 - base CORTECO product number.

01034649B - aftermarket catalogue reference used for this product.

82034649 - additional CORTECO reference.

FPM - fluoroelastomer material used for the sealing element.

B1BASLSFRDX46 - exact profile designation of this specific Simmerring variant.

65x95x11/16 mm - complete dimensional specification.

Dimensions of CORTECO 01034649

The complete dimensions are:

65x95x11/16 mm

where:

• d = 65 mm - inside diameter
• D = 95 mm - outside diameter
• B1 = 11 mm - basic axial width
• B2 = 16 mm - overall axial dimension

The complete designation:

65x95x11/16 mm

should be retained when identifying this product.

It should not be simplified to:

65x95x11 mm

because the 16 mm dimension is part of the geometry of this specific seal construction.

FPM fluoroelastomer

CORTECO specifies:

FPM

for CORTECO 01034649.

FPM is the European designation commonly used for the fluoroelastomer material family also widely designated as FKM.

Fluoroelastomers are used in technical radial shaft seals where their particular resistance characteristics are required by the application.

Correct selection should take into account:

• lubricant or operating medium
• operating temperature
• shaft speed
• shaft surface condition
• lubrication conditions
• differential design
• manufacturer requirements

A specific operating temperature range should not be assigned to CORTECO 01034649 solely from generic FPM material properties. Actual limits depend on the precise compound and operating conditions.

FPM/FKM should also not automatically be described as Viton. Viton is a trademark used for specific fluoroelastomer materials.

B1BASLSFRDX46 construction

The exact CORTECO profile designation is:

B1BASLSFRDX46

This designation is an important part of the technical identity of CORTECO 01034649.

For the exact 01034649B reference, product data also identifies:

• additional dust lip
• right-hand directional sealing structure
• 11/16 mm axial geometry

When evaluating a possible alternative, the complete combination should therefore be considered:

FPM + B1BASLSFRDX46 + 65x95x11/16 mm

Individual letters and numbers within B1BASLSFRDX46 should not be expanded into unsupported technical meanings unless explicitly defined by CORTECO for this product.

Right-hand directional sealing structure

Product data for CORTECO 01034649B specifies:

Right-hand Twist

This indicates a right-hand directional sealing structure.

Directionality is an important feature when selecting an equivalent seal.

A directional radial shaft seal should not automatically be replaced by a seal with the opposite directional characteristic simply because its basic dimensions are identical.

The required shaft rotation and exact installation position should be confirmed before replacement.

Additional dust lip

CORTECO 01034649B incorporates an additional dust lip.

This auxiliary lip helps protect the primary sealing area against external contamination.

Depending on operating conditions, contamination may include:

• road dust
• dirt
• fine particles
• moisture
• general environmental contamination

This construction feature is particularly relevant when comparing seals intended for drivetrain, differential and axle applications.

CORTECO 01034649 - differential shaft oil seal

CORTECO 01034649B is catalogued as a:

differential shaft oil seal

Application data associates this reference with specified DAF commercial vehicle drivetrain applications.

Depending on the exact vehicle and axle configuration, the seal is associated with differential and rear-axle sealing positions.

Compatibility should always be verified using the OE number, vehicle configuration and exact installation position.

CORTECO 01034649 and DAF 1401069

A confirmed DAF reference for this seal is:

DAF 1401069

The cross-reference relationship is:

CORTECO 01034649 / 01034649B

CORTECO 82034649

DAF 1401069

This provides a more reliable basis for product identification than dimensions alone.

Where the removed component or vehicle documentation specifies DAF 1401069, CORTECO 01034649B is catalogued as a corresponding reference.

CORTECO 01034649 and DAF AMPA068

An additional confirmed DAF reference is:

AMPA068

The product may therefore be identified through either of the following DAF references:

DAF 1401069

DAF AMPA068

Both are associated with CORTECO 01034649B in application data.

DAF applications

Application catalogues associate CORTECO 01034649B with specified DAF commercial vehicles, including selected configurations within the:

• DAF LF 45 family
• DAF LF 55 family
• DAF 55 family

The seal is associated with differential/rear-axle applications.

This does not mean that CORTECO 01034649 fits every DAF LF 45, LF 55 or DAF 55.

Exact compatibility should be confirmed using:

• DAF OE number
• vehicle model and version
• axle specification
• exact installation position
• seal dimensions
• CORTECO profile

CORTECO 01034649 vs a standard 65x95 oil seal

The basic:

65x95 mm

diameters are not sufficient to confirm interchangeability.

CORTECO 01034649 has the complete dimensional specification:

65x95x11/16 mm

combined with:

FPM + B1BASLSFRDX46

Other important characteristics include:

• 11/16 mm axial geometry
• additional dust lip
• right-hand directional sealing structure
• differential application
• DAF cross-references

A standard 65x95 radial shaft seal should therefore not automatically be considered an equivalent.

Why is the 11/16 mm dimension important?

CORTECO 01034649B is specified with two axial dimensions:

11 mm

and:

16 mm

The complete size should therefore be written as:

65x95x11/16 mm

The 16 mm value describes the additional overall axial dimension of the seal construction.

Reducing the product designation to 65x95x11 mm removes information that can be important when identifying the correct seal and evaluating interchangeability.

How to select CORTECO 01034649 correctly

The safest starting point is the exact manufacturer reference:

CORTECO 01034649 / 01034649B

or one of the confirmed DAF references:

1401069

AMPA068

Then verify:

1. inside diameter - 65 mm
2. outside diameter - 95 mm
3. basic axial width - 11 mm
4. overall axial dimension - 16 mm
5. FPM material
6. B1BASLSFRDX46 profile
7. additional dust lip
8. right-hand directional structure
9. exact installation position

Selection and interchangeability checklist

Before ordering, verify:

• CORTECO 01034649 / 01034649B
• CORTECO 82034649
• DAF 1401069 / AMPA068, where applicable
• d = 65 mm
• D = 95 mm
• B1 = 11 mm
• B2 = 16 mm
• FPM material
• B1BASLSFRDX46 profile
• additional dust lip
• right-hand directional structure
• differential/axle installation position

Matching 65x95 mm diameters alone do not confirm full technical interchangeability.

Installation of CORTECO 01034649

Before installation, thoroughly clean the seal housing and mating shaft surface.

Inspect:

• shaft sealing surface
• wear grooves
• scratches
• burrs
• corrosion
• housing condition
• alignment
• shaft runout
• bearing play

Install the seal evenly and squarely using an appropriate installation tool.

Protect the primary sealing area and additional dust lip against cutting, folding or deformation during assembly.

For a directional seal, correct orientation and the required shaft rotation should also be verified before installation.

What should be checked if the differential seal was leaking?

If the previous seal was leaking, the surrounding assembly should also be inspected.

Check:

• shaft or flange sealing surface
• wear grooves
• shaft runout
• bearing play
• bearing condition
• alignment
• seal housing
• lubricant type and level
• differential or axle breather, where applicable

Installing a new CORTECO 01034649 may not permanently solve the problem if the original leak was caused by shaft wear, excessive bearing clearance, misalignment or another mechanical fault.
