Technical data

CORTECO 01033796B dimensions

The complete catalogue dimensions are:

44x69x10/15 mm

where:

• 44 mm - inside diameter

A simplified description such as 44x69x10 mm does not represent the complete geometry of CORTECO 01033796B.

What does CORTECO 01033796B ACM B1BASFSLRSX6 mean?

01033796B is the CORTECO catalogue part number.

82033796 is an additional commercial reference associated with this product.

ACM identifies polyacrylate rubber as the elastomer material.

B1BASFSLRSX6 is the design designation specified for this CORTECO reference.

The complete technical identification is:

CORTECO 01033796B - ACM - B1BASFSLRSX6 - 44x69x10/15 mm

When selecting an alternative, the complete specification should be compared rather than only the 44 mm and 69 mm diameters.

ACM material

CORTECO 01033796B is manufactured from ACM, also known as polyacrylate rubber.

ACM is an elastomer used in automotive sealing applications, including drivetrain systems where resistance to oils and elevated operating temperatures is required.

For CORTECO 01033796B, ACM is part of the specified product construction and should be considered when selecting a replacement.

A 44x69 mm seal manufactured from another elastomer should not automatically be considered equivalent solely because its nominal dimensions match.

B1BASFSLRSX6 design

CORTECO specifies the design of reference 01033796B as:

B1BASFSLRSX6

This designation is an important part of the technical identification.

Catalogue data also specifies:

• dust protection lip

• left-hand twist

Therefore, when selecting an alternative to CORTECO 01033796B, it is important to verify not only the dimensions 44x69x10/15 mm but also the seal design and required directional structure.

Left-hand twist

CORTECO 01033796B is specified with:

left-hand twist

The directional structure is an important characteristic of this radial shaft seal.

A directional seal should not automatically be replaced with a seal having an opposite twist direction merely because the nominal dimensions are identical.

For this reason, the left-hand twist specification should be retained when identifying CORTECO 01033796B.

Dust lip

Catalogue data confirms that CORTECO 01033796B is equipped with a dust lip.

The additional lip helps protect the primary sealing area against external contamination.

This feature should also be considered when comparing CORTECO 01033796B with other 44x69 mm radial shaft seals.

Differential shaft seal

CORTECO 01033796B is catalogued as a:

differential shaft seal

It is also listed in parts catalogues as a pinion shaft seal.

The seal is used in drivetrain assemblies associated with the differential.

The exact installation position should always be verified for the specific vehicle using the OE number, drivetrain configuration and, where necessary, the VIN.

CORTECO 01033796B OE numbers

Confirmed OE and reference numbers associated with CORTECO 01033796B include:

• BMW 31521428678

• DANA 50120

BMW references may also appear in formatted notation:

• BMW 31 52 1 428 678

• BMW 31 52 7 507 697

For search and identification purposes, both continuous and manufacturer-formatted OE numbers may be useful.

CORTECO 01033796B for BMW

One of the principal OE references associated with CORTECO 01033796B is:

BMW 31521428678

Another BMW reference found in catalogue data is:

BMW 31527507697

CORTECO 01033796B is catalogued for selected drivetrain configurations across several BMW model families, including selected versions of:

• BMW 4 Series

• BMW 5 Series

• BMW 6 Series

• BMW 7 Series

• BMW X1

• BMW X3

• BMW X4

• BMW X5

This does not mean that the seal fits every version of these vehicles.

Compatibility depends on the drivetrain and differential configuration. The OE number or VIN should therefore be checked before ordering.

CORTECO 01033796B for Land Rover

A confirmed Land Rover OE reference is:

LAND ROVER LR007769

Catalogue data associates CORTECO 01033796B with selected Land Rover drivetrain applications.

The LR007769 reference should be compared with the number required for the specific vehicle and differential assembly before installation.

CORTECO 01033796B - DANA 50120

Another confirmed reference associated with this product is:

DANA 50120

This is particularly useful when identifying the seal directly through drivetrain or differential component documentation.

CORTECO 01033796B vs standard 44x69 oil seals

CORTECO 01033796B should not be treated as an ordinary 44x69 mm radial shaft seal.

When selecting a replacement, verify:

• dimensions 44x69x10/15 mm

• ACM material

• B1BASFSLRSX6 design

• dust lip

• left-hand twist

• OE reference

• installation position

Two radial shaft seals with the same 44x69 mm diameters may have different constructions and intended applications.

Matching nominal dimensions alone does not establish interchangeability.

Selection and interchangeability

Before purchasing CORTECO 01033796B, verify:

1. CORTECO part number 01033796B.

2. Dimensions 44x69x10/15 mm.

3. ACM material.

4. B1BASFSLRSX6 design.

5. Presence of the dust lip.

6. Left-hand twist.

7. OE number of the original seal.

8. Installation position.

9. Differential or drivetrain version.

10. Vehicle compatibility by VIN where required.

Dimensional compatibility alone does not guarantee complete interchangeability.

Installation

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

Check:

• shaft surface condition

• housing condition

• absence of burrs and sharp edges

• correct seal orientation

• correct directional installation

• dimensional compatibility

• correct seating in the housing

During installation, protect both the primary sealing lip and the dust lip against damage.

The seal should be installed evenly and axially without tilting or permanent deformation.
