When selecting a replacement, consider not only the dimensions but also the FPM material, LHTC profile, directional design and installation position.

CORTECO 19035187 Dimensions

Catalogue dimensions:

• inner diameter: 99 mm
• outer diameter: 119 mm
• width: 9.5 mm

Complete dimensions:

99x119x9.5 mm

The 9.5 mm width is part of the exact catalogue specification and should not be rounded to 10 mm when identifying the product.

Dimensions alone are also insufficient to confirm interchangeability with another crankshaft seal.

FPM - Fluoroelastomer

CORTECO 19035187 is manufactured from:

FPM - fluoroelastomer / fluorocarbon rubber

FPM is widely used in demanding automotive and industrial sealing systems.

Typical characteristics associated with fluoroelastomers include:

• very good resistance to many oils,
• good resistance to many fuels,
• good resistance to lubricants,
• good ageing resistance,
• resistance to many chemical media,
• suitability for demanding sealing applications.

Actual performance depends on the specific FPM compound, operating medium, temperature, shaft speed and application conditions.

A universal operating temperature range should therefore not be assigned to this specific CORTECO reference solely from generic FPM material data.

CORTECO LHTC Profile

The confirmed CORTECO profile designation is:

LHTC

For CORTECO 19035187, the following directional design is also confirmed:

Left-hand Twist

Directionality is an important technical characteristic of this seal.

The individual letters of the LHTC designation should not automatically be decoded using another manufacturer's seal nomenclature.

For technical identification, retain the complete designation:

CORTECO 19035187 FPM LHTC 99x119x9.5 mm

What Does Left-hand Twist Mean?

Left-hand Twist describes a directional characteristic of the sealing structure operating in relation to the rotational direction of the shaft.

It does not mean that the seal has a conventional left-hand screw thread.

From a replacement-selection perspective, the important point is that directionality forms part of the seal construction.

A 99x119x9.5 mm seal with a different profile or directional characteristic should therefore not automatically be considered interchangeable with CORTECO 19035187.

CORTECO 19035187 - Crankshaft Seal

CORTECO 19035187B is catalogued as a:

crankshaft radial shaft seal

Installation position:

transmission side

This position is also commonly described as the rear crankshaft seal position, where the engine connects to the transmission.

For a specific TOYOTA application, compatibility should be verified using the OE reference and the exact vehicle and engine version.

CORTECO 19035187 and TOYOTA 90311-99009

The confirmed OE reference is:

TOYOTA 90311-99009

The same number may also be written without separators:

9031199009

The product may therefore be searched as:

TOYOTA 90311-99009

TOYOTA 9031199009

90311-99009 oil seal

90311-99009 crankshaft seal

9031199009 shaft seal

as well as by the CORTECO references:

CORTECO 19035187

CORTECO 19035187B

CORTECO 82035187

For a specific vehicle, final compatibility should be confirmed using the relevant TOYOTA parts catalogue or vehicle identification data.

CORTECO 19035187 vs Standard 99x119x9.5 Oil Seal

A standard oil seal measuring:

99x119x9.5 mm

should not automatically be considered interchangeable with CORTECO 19035187.

The following characteristics should be compared:

• 99 mm inner diameter,
• 119 mm outer diameter,
• 9.5 mm width,
• FPM material,
• LHTC profile,
• Left-hand Twist directional design,
• complete seal construction,
• installation position,
• OE reference.

Matching nominal dimensions alone does not confirm complete technical interchangeability.

Can a 99x119x10 Seal Be Used Instead?

This should not be assumed.

The exact catalogue dimensions of CORTECO 19035187 are:

99x119x9.5 mm

The difference between 9.5 mm and 10 mm can affect the installation position, sealing lip contact location and interaction with the surrounding components.

The catalogue width of 9.5 mm should therefore be retained unless a manufacturer or reliable technical catalogue explicitly confirms a specific alternative.

Can NBR Replace FPM?

Not automatically.

CORTECO 19035187 is manufactured from:

FPM

NBR and FPM belong to different elastomer families and have different material characteristics.

Before changing the seal material, verify:

• operating medium,
• operating temperature,
• shaft speed,
• lubrication conditions,
• seal construction,
• directional requirements,
• engine manufacturer's requirements.

Matching dimensions alone do not confirm material or constructional interchangeability.

How to Select a Replacement for CORTECO 19035187

Verify:

• reference: 19035187 / 19035187B
• commercial number: 82035187
• inner diameter: 99 mm
• outer diameter: 119 mm
• width: 9.5 mm
• material: FPM
• profile: LHTC
• directional design: Left-hand Twist
• installation position: transmission side
• complete seal construction.

For TOYOTA applications, also verify:

OE 90311-99009

Selection by the complete CORTECO reference or confirmed OE number is more reliable than selection based solely on dimensions.

Installation Recommendations

Before installation, carefully clean and inspect all mating surfaces.

Check:

• crankshaft sealing surface,
• previous sealing lip contact area,
• absence of excessive wear grooves,
• absence of burrs,
• absence of sharp edges,
• absence of corrosion,
• housing condition,
• correct seal orientation,
• compatibility of the rotational direction with the Left-hand Twist design.

Protect the sealing lip against damage during installation.

The seal should be pressed evenly into position using an appropriate installation tool.

For a rear crankshaft seal, particular attention should be paid to the condition of the crankshaft surface where the previous sealing lip operated.
