Technical data - CORTECO 01034875

What does CORTECO 01034875 BF RWDR-KOMBI mean?

The complete product identification is:

CORTECO 01034875 BF RWDR-KOMBI 45x64.85/71.2x8.9/14.7 mm

Each element helps distinguish this product from conventional radial shaft oil seals with simpler geometry.

CORTECO - manufacturer of the sealing component.

01034875 - CORTECO product identification number.

01034875B - reference commonly found in aftermarket catalogue systems.

82034875 - additional CORTECO reference associated with this product.

BF - type designation for this specific version.

RWDR-KOMBI - designation describing the combined radial shaft sealing construction.

ACM - polyacrylate rubber used as the elastomeric sealing material.

45x64.85/71.2x8.9/14.7 mm - complete compound dimensional specification.

For accurate identification, the complete geometry and construction should be retained. This product should not be simplified to a generic 45x65 mm oil seal.

Dimensions of CORTECO 01034875

The complete dimensional specification is:

45x64.85/71.2x8.9/14.7 mm

where:

• d = 45 mm - inside diameter
• D1 = 64.85 mm - first outside diameter
• D2 = 71.2 mm - second outside diameter
• B1 = 8.9 mm - first height
• B2 = 14.7 mm - overall height

Some catalogue systems may round the first outside diameter to 64.8 mm or 65 mm.

For precise technical identification, the correct value should be retained as:

64.85 mm

and the complete dimensional designation as:

45x64.85/71.2x8.9/14.7 mm

Why is the 45x64.85/71.2x8.9/14.7 mm geometry important?

CORTECO 01034875 is not a conventional radial shaft seal described by one outside diameter and one width.

The two outside diameters:

64.85/71.2 mm

and two height values:

8.9/14.7 mm

describe the compound geometry of this specific sealing component.

This is particularly important when evaluating replacement products.

A conventional 45x65x9 mm seal may appear dimensionally similar in its basic sealing section, but that does not establish interchangeability with CORTECO 01034875.

ACM - Polyacrylate Rubber

CORTECO 01034875 is manufactured from:

ACM - Polyacrylate Rubber

ACM elastomers are used in sealing systems for transmissions, drivetrains and differentials where the material must operate with the specified lubricant and under the conditions of the particular assembly.

When evaluating the seal for an application, consider:

• lubricant type
• actual operating temperature
• shaft surface speed
• lubrication conditions
• transmission design
• differential design
• mating surface condition
• vehicle or transmission manufacturer requirements

A specific operating temperature range should not be assigned to CORTECO 01034875 solely from generic ACM material data.

BF RWDR-KOMBI construction

The product is identified with:

BF RWDR-KOMBI

RWDR is used in technical terminology for a radial shaft sealing ring, while KOMBI identifies a more complex combined sealing configuration.

For CORTECO 01034875, the special nature of the construction is also evident from its compound geometry:

45x64.85/71.2x8.9/14.7 mm

When selecting an alternative, the complete construction should therefore be considered rather than only the 45 mm shaft diameter and approximate 65 mm housing diameter.

The BF designation should also be retained as part of the exact product identification. It should not be replaced with another CORTECO profile code unless interchangeability is specifically confirmed.

CORTECO 01034875 as a differential oil seal

CORTECO 01034875B is classified in aftermarket catalogues as a:

differential radial shaft oil seal

In specified vehicle applications, it is also used as a transmission axle shaft or driveshaft seal.

The component seals the area where a rotating shaft passes through the housing of a transmission or differential assembly.

The exact installation position must always be confirmed according to the OE reference and documentation for the specific vehicle or transmission.

CORTECO 01034875 vs a standard 45x65 mm oil seal

CORTECO 01034875 should not automatically be replaced by a conventional radial shaft oil seal with dimensions close to:

45x65 mm

For CORTECO 01034875, verify:

• 45 mm inside diameter
• D1 = 64.85 mm outside diameter
• D2 = 71.2 mm second outside diameter
• B1 = 8.9 mm height
• B2 = 14.7 mm overall height
• ACM material
• BF type
• RWDR-KOMBI construction
• OE reference
• installation position

Similar basic dimensions do not establish full technical interchangeability.

The compound 64.85/71.2 mm outside geometry and 8.9/14.7 mm height are particularly important for this product.

How to select CORTECO 01034875 correctly

The safest starting point is identification by:

CORTECO 01034875 / 01034875B

or a confirmed OE reference:

Citroen 312160

Fiat 55207480

Peugeot 312160

Saab 55355129

Then verify:

• ACM material
• BF type
• RWDR-KOMBI construction
• complete 45x64.85/71.2x8.9/14.7 mm dimensions
• transmission type
• installation position

For vehicle applications, additional confirmation using the VIN and the relevant vehicle parts catalogue is recommended.

Selection and interchangeability checklist

Before ordering CORTECO 01034875, check:

• CORTECO 01034875 / 01034875B
• OE reference
• ACM material
• BF version
• RWDR-KOMBI construction
• 45 mm inside diameter
• 64.85/71.2 mm outside geometry
• 8.9/14.7 mm height
• transmission type
• installation position

If the existing seal has similar basic dimensions but different external geometry or overall height, interchangeability should not be assumed.

Installation of CORTECO 01034875

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

Check for:

• scratches
• burrs
• corrosion
• sharp edges
• wear grooves
• mechanical damage

Because of the compound geometry of CORTECO 01034875, correct installation depth and orientation are particularly important.

The seal should be installed evenly and squarely using a fitting tool that applies force to the appropriate structural surface.

Installation force should not be applied directly to the functional sealing elements.

What should be checked when an axle shaft or differential seal leaks?

If the previous seal was leaking, inspect the surrounding components before installing the new CORTECO 01034875.

Check:

• axle shaft or shaft sealing surface
• wear grooves
• shaft runout
• bearing play
• transmission bearing condition
• alignment
• seal housing condition
• lubricant level
• correct lubricant specification

Oil leakage is not always caused solely by deterioration of the radial shaft seal. Excessive shaft movement or a damaged sealing surface can cause leakage even after a new seal has been installed.
