CORTECO 20029180 PTFE BAPTSLRSX7 86x100x10 Crankshaft Seal

CORTECO 20029180 / 20029180B BAPTSLRSX7 is a crankshaft radial shaft seal measuring 86x100x10 mm, manufactured from PTFE/ACM. The seal features a left-hand directional sealing structure and an additional dust lip and is designed for installation on the transmission side of the crankshaft. Important OE references include Ford 1962331 and Nissan 1227943G00, 1227943G02 and 122797C600.

CORTECO 20029180 - Characteristics

The complete technical identity of this product can be expressed as:

CORTECO -> 20029180 / 20029180B -> PTFE/ACM -> BAPTSLRSX7 -> 86x100x10 mm -> left-hand twist -> dust lip -> transmission-side crankshaft seal -> Ford / Nissan

The complete specification is important because dimensions alone do not establish technical interchangeability.

A generic 86x100x10 mm oil seal should not automatically be considered a replacement for CORTECO 20029180B.

Dimensions

The confirmed dimensions are:

Inside Diameter: 86 mm
Outside Diameter: 100 mm
Width / Height: 10 mm
Complete Size: 86x100x10 mm

These dimensions are consistently specified for CORTECO 20029180B in both older CORTECO dimensional data and current catalogues.

PTFE/ACM Material

The current material specification is:

PTFE - polytetrafluoroethylene
ACM - polyacrylate rubber

Current technical catalogues explicitly specify PTFE/ACM for CORTECO 20029180B.

The older CORTECO dimensional catalogue uses the abbreviation T/A for this reference, while other historical listings describe the product as TFE. Current catalogue data provide the more precise PTFE/ACM designation.

This material specification should be considered when selecting a replacement. An NBR or FPM seal with the same 86x100x10 mm dimensions should not automatically be treated as technically equivalent.

BAPTSLRSX7 Seal Design

Older CORTECO dimensional data directly identify the product as:

20029180B -> BAPTSLRSX7 -> 86x100x10 mm.

This confirms the BAPTSLRSX7 designation in your original product data.

Current TecDoc-based catalogues may instead show the trade designation:

BASLRSX7 Simmerring

and trade number:

82029180.

For this product page, I would retain BAPTSLRSX7 in the H1 because it is the historical CORTECO designation directly associated with reference 20029180B, while BASLRSX7 can additionally be included in the technical specification for current catalogue searches.

Left-Hand Directional Design

CORTECO 20029180B is specified with a:

Left-hand Twist

directional sealing structure.

Directionality is an important characteristic of this crankshaft seal. A dimensionally identical seal with a different directional sealing geometry should not automatically be considered interchangeable.

Additional Dust Lip

CORTECO 20029180B incorporates an additional dust lip.

The dust lip provides an additional barrier on the external side of the main sealing zone and helps restrict contaminants from reaching the primary sealing interface.

The presence of this protective lip is therefore another parameter that should be checked when comparing alternative 86x100x10 mm seals.

Elastomer-Coated Outer Surface

The product uses an elastomer-coated outer surface. In this construction, the outer circumference of the seal provides the static sealing interface with the housing.

When replacing the seal, both the dynamic sealing interface at the shaft and the condition of the housing bore should be considered.

The exact outer-surface geometry should not be inferred solely from illustrative product photographs because catalogue images may show a different seal design or material.

Transmission-Side Crankshaft Seal

CORTECO 20029180B is classified as a:

Crankshaft seal / radial shaft seal / oil seal

and the specified fitting position is:

Transmission Side / Gearbox Side.

It can therefore also be described as a rear crankshaft seal in its designated engine applications.

This distinction is important because a front crankshaft seal may have a completely different sealing geometry even if its dimensions are similar.

Nissan 2.3 D Application

Historical CORTECO catalogue information identifies this reference as:

86x100x10 TFE BAPTSLRSX7 - rear crankshaft - Nissan 2.3 D.

This makes Nissan 2.3 D rear crankshaft seal a technically relevant search phrase for the product.

However, the seal should not be selected solely by engine displacement. The exact Nissan OE number and vehicle application should always be verified.

Nissan OE References

The confirmed Nissan OE numbers are:

NISSAN 1227943G00
NISSAN 1227943G02
NISSAN 122797C600.

These OE references provide a precise method of identifying CORTECO 20029180B.

Current application catalogues associate the seal with selected Nissan vehicle families including Cabstar, Navara, Pathfinder, Patrol, Pick Up, Serena, Terrano, Trade, Urvan and Vanette, depending on engine and production version.

Vehicle compatibility must therefore be checked against the exact OE reference and engine configuration.

Ford OE 1962331

The corresponding Ford OE reference is:

FORD 1962331.

Current application catalogues also associate CORTECO 20029180B with selected Ford Maverick applications.

Again, this does not mean universal compatibility with every Ford Maverick. The OE number and exact vehicle specification should be checked.

Cross-References

Important aftermarket cross-references include:

AJUSA: 15045200
ELRING: 247.380
GLASER: P76474-01
PAYEN: NJ829
VICTOR REINZ: 81-53334-00.

These references provide additional routes for identifying the product, but the complete technical specification should still be compared before substitution.

Product Images and Actual Seal Construction

Product photographs used in online catalogues can sometimes be illustrative rather than an exact photograph of CORTECO 20029180B.

This is particularly important if an image shows a standard BASLX7 NBR seal, while the actual product being offered is the PTFE/ACM CORTECO 20029180B.

Therefore, product selection should be based primarily on:

CORTECO reference -> dimensions -> material -> seal design -> directionality -> OE number

rather than on visual similarity alone.

Selection and Interchangeability

When selecting a replacement for CORTECO 20029180 / 20029180B, verify:

• CORTECO reference 20029180 / 20029180B
• inside diameter: 86 mm
• outside diameter: 100 mm
• width: 10 mm
• PTFE/ACM material
• BAPTSLRSX7 design
• left-hand directional structure
• additional dust lip
• transmission-side fitting position
• relevant Ford or Nissan OE reference

Matching the 86x100x10 mm dimensions alone does not establish full technical interchangeability.
