Technical data - CORTECO 01036820

What does CORTECO 01036820 ACM B1BASLRD mean?

The complete product identification is:

CORTECO 01036820 ACM B1BASLRD 40x65x10/15 mm

Each element is relevant when identifying the correct seal.

CORTECO - manufacturer of the radial shaft seal.

01036820 - CORTECO product identification number.

01036820B - reference format found in aftermarket catalogue systems and CORTECO dimensional data.

82036820 - additional commercial reference associated with this product.

ACM - polyacrylate rubber used as the sealing elastomer.

B1BASLRD - exact construction designation of this Simmerring version.

40x65x10/15 mm - complete dimensional specification.

RD - identifies the right-hand characteristic associated with this seal construction.

The seal should therefore be identified by its complete construction and dimensions, not simply as a 40x65 mm oil seal.

Dimensions of CORTECO 01036820

The correct dimensional specification is:

40x65x10/15 mm

where:

• d = 40 mm - inside diameter
• D = 65 mm - outside diameter
• B1 = 10 mm - first height
• B2 = 15 mm - second height

The:

10/15 mm

height specification is an important part of the product geometry.

CORTECO 01036820 should therefore not be simplified to a standard:

40x65x10 mm

radial shaft seal.

A seal with the same 40 mm shaft diameter and 65 mm housing diameter may still have a different construction and installation geometry.

ACM - Polyacrylate Rubber

CORTECO 01036820 is manufactured from:

ACM - Polyacrylate Rubber

ACM elastomers are used in sealing systems for drivetrains, transmissions, axles and differentials where compatibility with the specified lubricant and operating conditions is required.

When selecting this seal, consider:

• lubricant type
• operating temperature
• shaft surface speed
• lubrication conditions
• differential design
• shaft sealing surface condition
• installation position
• vehicle manufacturer requirements

An exact universal temperature range should not be assigned to CORTECO 01036820 solely from general ACM material properties. The limits depend on the specific compound and application conditions.

B1BASLRD construction

The exact construction designation is:

B1BASLRD

This designation is an integral part of the technical identity of CORTECO 01036820.

For this specific product, catalogue data confirms:

• ACM material
• 40x65x10/15 mm dimensions
• additional dust lip
• right-hand sealing characteristic
• front axle installation
• differential shaft sealing application

For this reason, CORTECO 01036820 should not be selected or replaced solely according to the 40x65 mm shaft and housing dimensions.

Right-hand RD sealing structure

Catalogue data for CORTECO 01036820 identifies a:

right-hand / RD sealing characteristic

The directional structure of the functional sealing area is an important technical feature.

In directional radial shaft seals, the geometry of the sealing zone is designed in relation to the intended movement of the mating shaft surface.

For this reason, when selecting an alternative, the directionality of the construction should be considered together with the dimensions and material.

A seal with the opposite directional characteristic should not automatically be considered an equivalent replacement for CORTECO 01036820.

Additional dust lip

CORTECO 01036820 incorporates an:

additional dust lip

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

This is particularly relevant in drivetrain and front axle assemblies exposed to:

• dust
• dirt
• water
• mud
• road contamination
• other external debris

The dust lip performs a different function from the primary lip responsible for retaining lubricant.

Its presence should therefore be checked when selecting a replacement seal.

CORTECO 01036820 as a differential shaft seal

Aftermarket catalogue data classifies this product as a:

differential radial shaft oil seal

with installation at the:

front axle

The seal operates within the drivetrain assembly where a rotating shaft must be sealed against lubricant loss while the sealing area is also protected from external contamination.

The exact installation location depends on the differential and drivetrain configuration of the particular vehicle.

CORTECO 01036820 vs Mercedes-Benz 2213530359

The principal confirmed Mercedes-Benz OE reference is:

2213530359

The same OE number is also commonly written as:

A2213530359

The prefix A is used in Mercedes-Benz part-number formatting.

Therefore, both:

Mercedes-Benz 2213530359

and:

Mercedes-Benz A2213530359

are important search and identification variants for this seal.

Aftermarket catalogue data associates these OE references with CORTECO 01036820 / 01036820B.

Mercedes-Benz applications

CORTECO 01036820 is catalogued for specified Mercedes-Benz drivetrain and differential applications, particularly in vehicle configurations using all-wheel-drive systems.

Application catalogues associate the corresponding OE reference with selected versions within Mercedes-Benz model families such as:

• Mercedes-Benz C-Class
• Mercedes-Benz E-Class
• Mercedes-Benz S-Class
• Mercedes-Benz CLS
• Mercedes-Benz GLK

Application data can vary according to model generation, engine, drivetrain and differential version.

The presence of a vehicle family in a catalogue does not mean that CORTECO 01036820 fits every version of that model.

The most reliable identification combination is:

OE reference + drivetrain configuration + differential version + installation position

For vehicle applications, compatibility should preferably be confirmed using the VIN and the manufacturer's parts catalogue.

CORTECO 01036820 vs other 40x65 oil seals

Not every radial shaft seal with basic dimensions of:

40x65 mm

is interchangeable with CORTECO 01036820.

When comparing alternatives, check:

• 40 mm inside diameter
• 65 mm outside diameter
• 10/15 mm height
• ACM material
• B1BASLRD construction
• additional dust lip
• right-hand RD characteristic
• OE reference
• installation position
• differential configuration

The combination:

40x65x10/15 + ACM + B1BASLRD + RD

provides much more precise identification than dimensions alone.

Matching shaft and housing diameters do not automatically establish complete technical interchangeability.

How to select CORTECO 01036820 correctly

The safest starting point is identification by:

CORTECO 01036820 / 01036820B

or the Mercedes-Benz OE reference:

2213530359

A2213530359

Then verify:

• ACM material
• B1BASLRD construction
• 40x65x10/15 mm dimensions
• additional dust lip
• right-hand sealing characteristic
• front axle installation
• exact differential application

For a vehicle application, confirmation using the VIN and Mercedes-Benz parts documentation is recommended.

Selection and interchangeability checklist

Before purchasing CORTECO 01036820, verify:

• CORTECO 01036820 / 01036820B
• Mercedes-Benz 2213530359 / A2213530359
• ACM material
• B1BASLRD construction
• 40 mm inside diameter
• 65 mm outside diameter
• 10/15 mm height
• additional dust lip
• right-hand RD characteristic
• installation position
• exact differential configuration

Identical basic dimensions do not automatically mean that two radial shaft seals are technically interchangeable.

Installation of CORTECO 01036820

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

Inspect the sealing area for:

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

Protect both the primary sealing lip and additional dust lip during installation.

Because CORTECO 01036820 has a directional sealing structure, the correct installation orientation must also be maintained.

The seal should be pressed evenly and squarely into the housing using an appropriate installation tool.

Avoid applying installation force directly to the functional sealing lips.

What should be checked when a differential seal is leaking?

If the previous differential seal was leaking, the condition of the surrounding components should also be inspected.

Check:

• shaft sealing surface
• shaft wear groove
• shaft runout
• bearing condition
• differential bearing play
• alignment
• seal housing
• correct lubricant specification and level

Installing a new CORTECO 01036820 may not eliminate leakage if the actual cause is a worn shaft surface, excessive movement or another mechanical problem within the differential.
