Technical data

CORTECO 20034699 dimensions

The exact dimensions are:

115x140x12 mm

where:

• 115 mm - inside diameter

• 140 mm - outside diameter

• 12 mm - width

Dimensions are an essential part of product identification, but they should not be the only selection criterion.

For CORTECO 20034699, the BAPTSLVRSX7 design, PTFE/ACM material technology, left-hand twist and installation position must also be considered.

What does CORTECO 20034699 T/A BAPTSLVRSX7 mean?

20034699 is the CORTECO catalogue reference.

T/A is the material designation used in the CORTECO dimensional catalogue for this reference.

Current application data describes the material as:

PTFE/ACM

BAPTSLVRSX7 is the complete CORTECO design designation associated with this seal.

The complete technical identification is therefore:

CORTECO 20034699 - T/A - BAPTSLVRSX7 - 115x140x12 mm

The complete specification should be retained when searching for an equivalent seal.

PTFE/ACM material technology

CORTECO 20034699 uses a PTFE/ACM material configuration.

PTFE, or polytetrafluoroethylene, is widely used in modern crankshaft sealing systems designed for demanding operating conditions.

ACM, or polyacrylate rubber, is an elastomer commonly used in automotive sealing applications.

For CORTECO 20034699, the material specification should not be simplified to NBR, FPM or another conventional sealing elastomer.

The correct catalogue identification is:

T/A - PTFE/ACM

BAPTSLVRSX7 design

CORTECO specifies the construction of reference 20034699 as:

BAPTSLVRSX7

This is an important technical identification feature.

A conventional 115x140x12 mm oil seal should not automatically be considered interchangeable with CORTECO 20034699.

When selecting a replacement, verify:

• BAPTSLVRSX7 design

• PTFE/ACM material

• dust lip

• left-hand twist

• transmission-side fitting position

• application and OE reference

Left-hand twist

Catalogue data specifies CORTECO 20034699 with:

left-hand twist

The directional sealing structure is an important characteristic of this crankshaft seal.

A directional radial shaft seal should not automatically be replaced by a seal with the opposite twist direction simply because the nominal dimensions are identical.

The correct directional specification should therefore be maintained when selecting an alternative.

Dust lip

CORTECO 20034699 is equipped with a dust lip.

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

This is another construction feature that should be considered when comparing CORTECO 20034699 with other 115x140x12 mm radial shaft seals.

Rear crankshaft seal

CORTECO 20034699 is catalogued as a:

crankshaft seal

Its fitting position is specified as:

transmission side

This means that the product is used as a:

rear crankshaft seal

This terminology is particularly important when searching for the correct crankshaft seal for Mercedes-Benz commercial vehicle engines.

CORTECO 20034699 for Mercedes-Benz Truck

The CORTECO dimensional catalogue assigns reference 20034699 to:

MERCEDES TR

meaning Mercedes-Benz Truck applications.

The product is therefore particularly relevant when searching for a rear crankshaft seal for selected Mercedes-Benz commercial vehicle engines.

Compatibility must still be confirmed for the exact engine and vehicle configuration.

CORTECO 20034699 for Mercedes-Benz Actros

CORTECO catalogue and application data associate this 115x140x12 mm PTFE/ACM seal with selected Mercedes-Benz Actros applications.

The reference is commonly described as:

rear crankshaft seal for Actros

The seal is installed on the transmission side of the crankshaft.

However, Mercedes-Benz Actros vehicles have been produced with numerous engine and drivetrain configurations.

Compatibility should therefore be confirmed using the engine specification, OE reference or VIN before installation.

CORTECO 20034699 for Mercedes-Benz Atego

CORTECO 20034699 also appears in application catalogues for selected Mercedes-Benz Atego commercial vehicle engines.

It is listed as a crankshaft radial shaft seal with:

• 115 mm inside diameter

• 140 mm outside diameter

• 12 mm width

• PTFE/ACM material

• transmission-side fitting position

• left-hand twist

• dust lip

Exact compatibility depends on the engine and vehicle configuration.

Transmission-side crankshaft seal

Because CORTECO 20034699 is fitted on the transmission side, the product may also be searched as:

transmission-side crankshaft seal

or:

rear main crankshaft seal

These terms refer to the installation position at the rear of the engine, where the crankshaft interfaces with the transmission/flywheel area.

The fitting position is an important selection criterion because front and rear crankshaft seals may have completely different dimensions, designs and directional sealing structures.

CORTECO 20034699 vs standard 115x140x12 oil seal

CORTECO 20034699 should not automatically be replaced with a conventional 115x140x12 mm radial shaft seal.

The complete specification includes:

• dimensions 115x140x12 mm

• T/A material designation

• PTFE/ACM material technology

• BAPTSLVRSX7 design

• dust lip

• left-hand twist

• transmission-side installation

• crankshaft application

Two seals with identical nominal dimensions can have different constructions and may not be interchangeable.

Selection and interchangeability

Before purchasing CORTECO 20034699, verify:

1. CORTECO part number 20034699.

2. Dimensions 115x140x12 mm.

3. T/A material designation.

4. PTFE/ACM material technology.

5. BAPTSLVRSX7 design.

6. Left-hand twist.

7. Presence of the dust lip.

8. Transmission-side fitting position.

9. Engine and vehicle version.

10. OE reference or VIN where required.

Matching dimensions alone do not guarantee interchangeability.

Installation of a PTFE crankshaft seal

PTFE crankshaft seals require particular care during installation.

Before installation:

• thoroughly clean the crankshaft sealing surface

• remove contamination and residues from the previous seal

• inspect the shaft surface for damage or excessive wear

• protect the sealing lip against sharp edges

• confirm the correct installation orientation

• follow the manufacturer's installation instructions

A PTFE sealing element should not automatically be handled in the same way as a conventional NBR radial shaft seal.

If the supplied product includes an installation sleeve or installation aid, it should be used according to the manufacturer's instructions.

Correct installation is essential for achieving the intended sealing performance and service life.
