CORTECO 01036358 24.5x41x6 ACM B1BASLRD Radial Shaft Seal

CORTECO 01036358 B1BASLRD is an ACM radial shaft seal measuring 24.5x41x6 mm, designed for a rotating shaft sealing position in manual transmissions. Its principal dimensions are 24.5 mm nominal shaft diameter, 41 mm outside diameter and 6 mm width. The specific B1BASLRD configuration incorporates an additional dust lip and a right-hand twist structure. The product is also catalogued under the CORTECO reference 01036358B.

CORTECO 01036358 B1BASLRD - Product Characteristics

The exact CORTECO size catalogue identifies 01036358 as an ACM B1BASLRD rotary shaft seal with dimensions 24.5x41x6 mm. Current aftermarket catalogue data identify the corresponding product as 01036358B, with the trade numbers 82836358 and B1BASLRD Simmerring.

This is a radial oil seal used at a rotating shaft interface. The primary sealing lip works against the shaft surface, while the confirmed additional dust lip provides a secondary barrier against contamination approaching the main sealing area.

The exact product is also specified with a right-hand twist. This directional feature is technically relevant when selecting a replacement and should not be ignored simply because another seal has the same 24.5x41x6 mm dimensions.

Dimensions

The verified dimensions of CORTECO 01036358 B1BASLRD are:

Nominal Shaft / Inner Diameter: 24.5 mm
Outside Diameter: 41 mm
Width / Height: 6 mm
Commercial Size: 24.5x41x6 mm

For this radial shaft seal, the dimensional sequence 24.5x41x6 mm identifies the nominal shaft diameter, outside diameter and axial seal width respectively. The CORTECO size catalogue explicitly lists 01036358 - ACM - B1BASLRD - 24.5 - 41 - 6.

Some current TecDoc-derived catalogues display an additional inner-diameter value of 25 mm alongside Inner Diameter 2 = 24.5 mm. Because the CORTECO size catalogue identifies this seal as 24.5x41x6 mm, 24.5x41x6 mm is retained here as the primary product size.

B1BASLRD Seal Construction

The exact design designation for this seal is B1BASLRD.

For the corresponding CORTECO 01036358B catalogue entry, technical databases confirm:

Material: ACM
Dust Lip: Yes
Swirl Type: Right-hand twist
Trade Designation: B1BASLRD Simmerring

The additional dust lip is separate from the primary sealing function. The main lip creates the sealing interface against the rotating shaft, while the dust lip helps limit external contamination reaching the primary sealing area.

The right-hand twist is also part of the specific configuration. Consequently, B1BASLRD should be treated as a relevant technical identifier, rather than reducing this product to a generic 24.5x41x6 oil seal.

ACM Polyacrylate Material

CORTECO 01036358 is manufactured from ACM, or polyacrylate rubber. The material specification is explicitly stated in the CORTECO size catalogue and confirmed for the 01036358B catalogue reference.

Material is an important parameter when selecting a rotary shaft seal. A 24.5x41x6 seal manufactured from NBR, FKM/FPM or another elastomer should not automatically be considered technically identical to this ACM version.

No specific operating-temperature range is assigned here to CORTECO 01036358. A generic temperature range for ACM would not prove the permissible operating limits of this exact seal and compound.

Dust Lip and Right-Hand Twist

Two construction details distinguish this reference from a generic radial oil seal of the same size.

The first is the additional dust lip, which creates a supplementary barrier on the external side of the primary sealing area.

The second is the confirmed right-hand twist. Directional sealing structures should be matched to the intended operating configuration. A left-hand, non-directional or otherwise different sealing structure should therefore not be assumed to be equivalent solely because its dimensions are 24.5x41x6 mm.

Manual Transmission Application

Current technical catalogues classify CORTECO 01036358B as a shaft seal, manual transmission. This is therefore a verified product category rather than an application inferred solely from the seal dimensions.

Catalogue fitment data associate this reference with multiple Alfa Romeo, Fiat, Opel and Vauxhall applications. Examples include Alfa Romeo 159 and MiTo and Opel Astra, Corsa and Insignia families. However, model name alone is insufficient for final fitment confirmation because compatibility can depend on engine, transmission, production period and vehicle specification.

For vehicle installation, selection should therefore be confirmed using the exact OE reference and, where necessary, the vehicle VIN or transmission identification.

OE / OEM Reference Numbers

Confirmed OE cross-references for the corresponding CORTECO 01036358B product are:

ALFA ROMEO: 55565322
GENERAL MOTORS / GM: 55565322
OPEL: 714952
VAUXHALL: 55565322
VAUXHALL: 714952

These references are consistently listed in current technical catalogues for this CORTECO seal.

The term OE reference is preferable to claiming that the product is "OE-approved". The available cross-reference data confirm association with these OE numbers but do not, by themselves, establish a separate manufacturer approval or certification.

CORTECO Product References

The following identifiers are relevant to this product:

01036358 - reference appearing in the CORTECO dimensional catalogue
01036358B - current catalogue / TecDoc product reference
82836358 - trade number
B1BASLRD Simmerring - trade/design designation
EAN: 3358960538239

The EAN and trade numbers are confirmed by current technical catalogue data.

These identifiers can assist product matching, but the complete technical configuration should still be checked when selecting a replacement.

Selection and Interchangeability

A replacement for CORTECO 01036358 B1BASLRD should not be selected from dimensions alone.

The critical comparison points are:

• nominal shaft diameter: 24.5 mm,
• outside diameter: 41 mm,
• width: 6 mm,
• ACM material,
• B1BASLRD design,
• additional dust lip,
• right-hand twist,
• OE reference where vehicle-specific identification is required,
• transmission and installation position.

A different manufacturer's 24.5x41x6 radial oil seal is therefore not automatically a direct technical replacement.

This is particularly important for a directional seal. Matching the three principal dimensions while ignoring the lip design or right-hand twist does not establish complete equivalence.

Installation Considerations

Before installation, the shaft running surface and housing bore should be inspected for damage, contamination and defects that could interfere with the seal.

The sealing lip and dust lip must not be cut, folded or damaged during assembly. The seal should be installed evenly and in the correct orientation for the transmission sealing position.

Because this exact reference has a right-hand twist, the directional configuration should be verified when replacing an existing seal. Installation requirements for the specific transmission or vehicle take priority over generic shaft-seal installation guidance.
