REAR BEARING SEAL FOR BD144 / BD154 ENGINE – PART NO. CAM199390

Rear bearing seal for International and McCormick engines

The CAM199390 rear bearing seal is an engine seal designed for use in various International Harvester and McCormick-International tractors and machines equipped with BD144 / BD154 series engines, depending on the specific application.

With an inner diameter of 95 mm, an outer diameter of 111.5 mm, and a width of 11 mm, this seal is installed at the rear bearing of the engine to ensure a tight seal and prevent oil leaks into the clutch area.

Replacing this seal is particularly recommended when an engine oil leak occurs between the engine and the transmission or during a complete engine overhaul.

What is the function of the rear bearing seal?

To provide a seal at the rear of the crankshaft

The rear bearing seal is mounted at the rear end of the crankshaft. Its purpose is to prevent oil from the engine from leaking into the clutch housing.

This part operates directly around a rotating component and must maintain its seal despite:

• the rotational speed of the crankshaft;
• engine temperature;
• variations in RPM;
• vibrations;
• long periods of operation.

Over the years, the seal lip may gradually harden or wear out. A leak may then develop at the junction between the engine and the transmission.

Compatible with International B250 and B275 tractors

Applications on older International series

The CAM199390 rear bearing seal is specifically designed for use in the following tractor models:

• International B250
• International B275

These models are paired with engines from the BD144 family, depending on their configuration.

When overhauling an engine, it is recommended to check the condition of both the front and rear seals at the same time, especially when the engine is completely disassembled.

Compatibility with International 276 tractors

Engine Gasket for International 276

Part number CAM199390 is also suitable for:

• International 276
• International 2276

These tractors share various engine components with several other models in the International lineup.

Compatibility with the International 2300 and 2350

Other International Applications

The rear bearing seal is also compatible with the following models:

• International 2300
• International 2350

Depending on the year of manufacture and engine configuration, it is always advisable to check the seal dimensions before installation.

The CAM199390 is also compatible with:

• International 354
• International 364

These tractors are among the applications that use mechanical components common to several International engine models.

Compatibility with the International 374 and 384

Installation on agricultural and industrial tractors

Part number CAM199390 is also suitable for:

• International 374
• International 384
• International 384 Industrial Version

For the 384 model, there may be several configurations depending on the application and market. Therefore, it is recommended to identify the specific motor.

Compatibility with the International 434 and 444

McCormick-International and International Harvester Applications

The CAM199390 rear bearing seal is also compatible with:

• McCormick-International 434 Diesel

What are the symptoms of a worn rear bearing seal?

A leak that is often visible between the engine and the transmission

The main symptom of a faulty rear seal is an oil leak in the area between the engine and the transmission.

Signs that may indicate wear include:

• oil stains under the clutch cover;
• a leak at the engine-transmission joint;
• a gradual drop in the engine oil level;
• oil in the clutch housing;
• clutch begins to slip if the disc is contaminated;
• persistent greasy marks after cleaning.

Before disassembling the tractor, it is important to confirm the exact source of the leak. A leak located higher up on the engine can sometimes drip down to the clutch housing area and give the impression that the rear seal is the cause.

Why replace the seal during an engine overhaul?

A worthwhile preventive measure

Replacing a rear main bearing seal generally requires extensive access to the rear of the engine.

When the engine has already been disassembled or separated from the transmission for another repair, it may be a good idea to replace the seal if its age or condition warrants it.

This procedure helps avoid having to perform another major disassembly a few months or years later just to fix an oil leak.

Check the crankshaft diameter

An important step before installing the new gasket

The seal lip is constantly in contact with a surface on the crankshaft. After many hours of use, this contact surface may develop a wear groove.

During disassembly, it is advisable to check for:

• a pronounced groove;
• scratches;
• corrosion;
• an uneven surface;
• signs of overheating.

If the flange is severely damaged, installing a new gasket alone may not be sufficient to ensure a lasting seal.

Installation Instructions for Seal CAM199390

Avoid damaging the lip during installation

Before installing the new seal, the housing must be completely clean.

It is recommended that you:

• Completely remove any residue from the old gasket;
• clean the crankshaft bearing surface;
• inspect the condition of the contact surface;
• Lightly lubricate the lip before installation, if the procedure calls for it;
• position the seal perfectly straight;
• use a suitable installation tool;
• avoid direct impacts that could deform the seal.

After reassembly, it is recommended to regularly check for leaks during the first few hours of operation.
