CORTECO 19016656 - Technical Data

What Does CORTECO 19016656 ACM RHTC Mean?

The complete designation identifies a specific CORTECO rotary shaft seal.

CORTECO - manufacturer and brand specialising in sealing technology.

19016656 - CORTECO reference for this specific product.

19016656B - reference also encountered in current parts catalogues and distribution channels.

82016656 - trade number associated with this product.

ACM - polyacrylate rubber used as the elastomer material.

RHTC - CORTECO profile designation assigned to this specific shaft seal.

27x43x9 mm - nominal dimensions: 27 mm inside diameter, 43 mm outside diameter and 9 mm width.

The RHTC construction and right-hand twist are technically important identification characteristics. A different 27x43x9 mm oil seal should not automatically be considered interchangeable with CORTECO 19016656.

CORTECO 19016656 Dimensions

The nominal dimensions are:

27x43x9 mm

where:

27 mm - inside diameter

43 mm - outside diameter

9 mm - seal width

These dimensions are confirmed for CORTECO 19016656B.

The 27 mm inside diameter corresponds to the nominal diameter of the mating shaft, while the 43 mm outside diameter corresponds to the nominal housing bore.

Dimensions alone are not sufficient to establish interchangeability. Material, profile, lip construction, twist direction and intended application should also be verified.

ACM - Polyacrylate Rubber

CORTECO specifies ACM, or polyacrylate rubber, for this shaft seal.

ACM is an elastomer used in technical sealing systems, including automotive drivetrain and transmission applications operating with compatible lubricants.

The general properties of ACM alone are not sufficient to define the exact operating limits of CORTECO 19016656.

Actual suitability depends on the specific elastomer compound, lubricant, temperature, shaft surface speed and construction of the complete sealing system.

For this reason, no unverified exact temperature, pressure or rotational speed limits are assigned to this SKU.

CORTECO RHTC Profile

CORTECO identifies this seal with the RHTC profile.

The profile is an integral part of the technical specification and should be considered when identifying the product or selecting an alternative.

For CORTECO 19016656B, catalogue data also confirms a right-hand twist.

The directional sealing structure is particularly important in rotary applications. A seal with the same 27x43x9 mm dimensions but a different twist direction or lip geometry should not automatically be treated as an equivalent.

Right-Hand Twist

CORTECO 19016656B is specified with a right-hand twist.

Directional sealing features are designed for a defined direction of shaft rotation. Their function is associated with the geometry of the sealing lip and the rotational conditions of the application.

This characteristic should therefore be checked when replacing the original seal.

A similar seal with left-hand twist or a non-directional sealing structure may have the same nominal dimensions but a different functional design.

Additional Dust Lip

CORTECO 19016656B is specified with an additional dust lip.

The auxiliary lip helps reduce the ingress of external contamination into the primary sealing area.

This is an important construction characteristic when comparing CORTECO 19016656 with other 27x43x9 mm shaft seals.

A seal with identical dimensions but without a dust lip should not automatically be considered a complete technical equivalent.

Construction and Operating Principle

CORTECO 19016656 is a radial rotary shaft seal designed to operate between a rotating shaft and a stationary housing.

The primary sealing lip works against the shaft surface and helps retain lubricant within the transmission assembly.

The additional dust lip provides a secondary barrier against contamination from the external side.

The RHTC profile additionally incorporates a defined directional characteristic associated with right-hand shaft rotation.

Correct operation therefore depends on more than the basic 27x43x9 mm dimensions. Shaft condition, installation direction, rotation direction, lubricant and seal material must also be compatible with the application.

Manual Transmission Shaft Seal

CORTECO 19016656 / 19016656B is catalogued as a manual transmission shaft seal.

This is important for product identification because the reference should not be treated merely as a universal 27x43x9 mm oil seal.

The product has OE references associated with Mazda, Isuzu, Opel and Vauxhall applications.

The exact installation position and vehicle compatibility should always be checked against the OE number and the specific transmission configuration.

OE Reference Numbers

The following OE references are associated with CORTECO 19016656B:

ISUZU 8943264410

MAZDA 060316103

OPEL 702634

OPEL 94326441

VAUXHALL 702634

OE numbers provide a more precise identification reference than dimensions or vehicle manufacturer alone.

When selecting this seal for a vehicle, the original OE reference, transmission configuration and installation position should be checked before installation.

Mazda OE 060316103

For Mazda applications, CORTECO 19016656B is associated with OE reference:

MAZDA 060316103

This reference can be used together with the CORTECO number and technical specification when identifying the correct transmission shaft seal.

Compatibility should not be assumed for every Mazda model simply because the dimensions are 27x43x9 mm.

Isuzu OE 8943264410

For Isuzu applications, the associated OE reference is:

ISUZU 8943264410

When selecting CORTECO 19016656 for an Isuzu transmission, this OE number provides an important identification point.

The exact vehicle and transmission version should still be verified.

Opel and Vauxhall OE References

CORTECO 19016656B is also associated with:

OPEL 702634

OPEL 94326441

VAUXHALL 702634

These references help identify the seal in applications where the same CORTECO construction is used under different vehicle manufacturer numbering systems.

CORTECO 19016656 vs Other 27x43x9 mm Shaft Seals

The nominal dimensions 27x43x9 mm are not sufficient to uniquely identify this product.

CORTECO 19016656 has the confirmed specification:

27x43x9 mm

ACM

RHTC

right-hand twist

additional dust lip

manual transmission application

This distinction is particularly important because CORTECO also catalogues other seals with the same 27x43x9 mm dimensions but different materials and directional characteristics.

For example, a 27x43x9 mm seal with a different material or left-hand twist should not automatically be considered interchangeable with CORTECO 19016656.

Alternative Designations and Reference Numbers

The product may be identified using designation variants such as:

Cross-Reference Numbers

Cross-reference catalogues associate CORTECO 19016656B with references including:

FEBI BILSTEIN 104418

PAYEN NJ484

These references can assist with product identification but should not be treated as proof of complete interchangeability without comparing the complete technical specification.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016656 / 19016656B, verify:

• complete CORTECO reference,
• dimensions 27x43x9 mm,
• ACM elastomer material,
• RHTC profile,
• right-hand twist,
• additional dust lip,
• OE reference of the original component,
• transmission type and installation position,
• shaft rotation direction,
• condition of the mating shaft surface,
• operating lubricant,
• requirements of the specific application.

Identical dimensions do not automatically mean complete interchangeability.

Differences in material, lip construction and directional sealing geometry can make two 27x43x9 mm seals technically different.

Installation of CORTECO 19016656

Before installation, carefully clean the housing bore and mating shaft surface.

The sealing lip contact surface should be free from corrosion, sharp edges, burrs and deep scratches that could damage the seal or cause leakage.

Install the seal squarely and evenly using an installation tool appropriate for its diameter and geometry.

Protect the primary sealing lip and additional dust lip against cutting, folding or deformation during assembly.

Because CORTECO 19016656B has a directional RHTC construction with right-hand twist, the shaft rotation direction and correct seal orientation should be verified before installation.
