CORTECO 49360685 BASLRSX7 ACM 28x77x8/15 Crankshaft Oil Seal

CORTECO 49360685 BASLRSX7 is an ACM radial shaft oil seal with dimensions 28x77x8/15 mm, specified for the crankshaft on the transmission side. The seal has a 28 mm inside diameter, 77 mm outside diameter and heights of 8 mm and 15 mm. Product data identify a dust lip and left-hand twist, while the confirmed ZF reference is 0734300235.

CORTECO 49360685 BASLRSX7 - Product Identification

The exact product specification is:

Manufacturer: CORTECO
Part Number: 49360685
Design: BASLRSX7
Product Type: Radial shaft seal / crankshaft oil seal
Material: ACM / polyacrylate rubber
Dimensions: 28x77x8/15 mm
Installation Position: Transmission side
Dust Protection: With dust lip
Swirl Type: Left-hand twist
OE Reference: ZF 0734300235
EAN: 3358960242365.

This combination should be used for precise product identification rather than relying on the 28x77 mm diameters alone.

Dimensions

The dimensional specification of CORTECO 49360685 is:

Inside Diameter: 28 mm
Outside Diameter: 77 mm
Height 1: 8 mm
Height 2: 15 mm
Complete Size: 28x77x8/15 mm.

The two height values are significant. The product should therefore be identified as 28x77x8/15 mm, rather than shortened to 28x77x8 mm when selecting the exact seal configuration.

BASLRSX7 Seal Design

BASLRSX7 is the design designation associated with CORTECO 49360685. Available technical catalogue data for this exact reference additionally specify a dust protection lip and left-hand twist.

The dust lip provides an additional sealing barrier on the external side of the primary sealing system.

The left-hand twist is a directional feature of the sealing lip area. It is therefore technically relevant when identifying the correct replacement and should not be ignored simply because another shaft seal has identical nominal dimensions.

Left-Hand Twist

For CORTECO 49360685, the swirl type is explicitly specified as left-hand twist.

This directional characteristic is important because shaft seals with hydrodynamic structures are designed with a defined rotational relationship. A seal of the same dimensions but with a different directional design should not automatically be considered equivalent.

For replacement selection, the complete combination 49360685 + BASLRSX7 + left-hand twist should therefore be checked.

ACM Polyacrylate Material

The sealing material of CORTECO 49360685 is ACM (polyacrylate rubber). This material specification is consistently reported for the exact reference.

ACM is an elastomer used in oil-sealing applications where resistance to lubricating oils and elevated operating temperatures is required.

However, material identification alone does not establish compatibility with every lubricant or operating temperature. Actual suitability should be evaluated against the fluid, temperature, shaft conditions and complete sealing arrangement.

Crankshaft Seal - Transmission Side

CORTECO 49360685 is catalogued as a crankshaft shaft seal installed on the transmission side.

This installation position is an important part of the product identity. It should not be described generically as a universal crankshaft seal or assumed to fit other crankshaft positions solely from its dimensions.

For vehicle or transmission identification, the OE reference should also be checked.

ZF 0734300235 Reference

The confirmed OE cross-reference for CORTECO 49360685 is:

ZF: 0734300235.

Multiple independent catalogues associate this exact ZF number with CORTECO 49360685.

The reference should nevertheless be verified against the specific vehicle, transmission or assembly before installation, particularly where several seal variants exist for the same vehicle family.

Selection and Interchangeability

A replacement for CORTECO 49360685 should not be selected solely from the 28x77 mm shaft and housing diameters.

The following characteristics should be compared together: 28 mm inside diameter, 77 mm outside diameter, 8/15 mm height configuration, ACM material, BASLRSX7 design, dust lip, left-hand twist and OE reference ZF 0734300235.

A shaft seal with the same basic diameters but a different lip geometry, material, directional structure or overall height is not automatically technically equivalent.
