1468376001 Pump Head for New Holland TM140: Specs, Applications & Replacement Guide

The 1468376001 Diesel Pump Head is a hydraulic head and rotor assembly used in Bosch VE-type mechanical distributor injection pumps. It is mainly designed for 6-cylinder diesel applications, including agricultural equipment such as the New Holland TM140 tractor.

As a key component inside the injection pump, the 1468376001 controls fuel pressurization, metering, and distribution to injector outlets according to the engine firing sequence.

Before replacement, always verify the original pump head number, injection pump model, cylinder configuration, rotation direction, and plunger specification.

1. What Is the 1468376001 Diesel Pump Head?

The 1468376001 is the hydraulic working section of a Bosch VE rotary distributor injection pump.

Its main functions include:

• Generating injection pressure through the plunger and barrel assembly
• Controlling fuel delivery quantity
• Distributing fuel to six injector outlets
• Maintaining stable injection performance

When the internal precision surfaces wear, fuel pressure decreases, causing starting problems, power loss, unstable idle, and excessive smoke.

2. Power Loss Under Load

Symptoms:

• Weak acceleration
• Poor pulling performance
• Black smoke during heavy operation

Cause: Worn hydraulic surfaces reduce fuel delivery efficiency.

3. Unstable Idle

Symptoms:

• RPM fluctuation
• Engine hunting at idle

Cause: Uneven fuel distribution between cylinders caused by internal wear.

4. Excessive Exhaust Smoke

Possible causes include:

• Reduced injection pressure
• Incorrect fuel delivery
• Poor injector atomization
• Incorrect injection timing

5. Fuel Mixing With Engine Oil

Symptoms:

• Rising oil level
• Diesel smell in engine oil

Cause: Internal leakage within the fuel injection system.

6. Engine No-Start Condition

Symptoms:

• Engine cranks but does not fire

Possible causes:

• Severe pump head wear
• Internal component seizure
• Fuel contamination damage

6. Main Causes of Pump Head Failure

Contaminated Fuel

Water and particles can damage the precision surfaces inside the pump head.

Poor Filtration

Damaged or overdue fuel filters allow contaminants into the injection system.

Normal Wear

Long-term operation gradually increases internal clearance and fuel leakage.

Incorrect Repair

Improper assembly or lack of calibration can reduce injection performance.

7. Replacement and Calibration Guide

Replacing the 1468376001 requires proper injection pump experience.

Before Replacement

Check:

• Fuel supply system
• Fuel filter condition
• Injector condition
• Injection timing

Confirm that the pump head is the actual cause of failure.

Installation Requirements

During replacement:

• Keep the working area clean
• Lubricate components with clean diesel fuel
• Replace damaged seals
• Install according to pump specifications

Test Bench Calibration

After installation, the injection pump should be tested and calibrated.

Calibration checks:

• Fuel delivery quantity
• Cylinder balance
• Injection timing
• Governor performance

A pump head replacement without calibration may result in incorrect engine performance.

8. Maintenance Tips

To extend pump head service life:

• Use clean diesel fuel
• Replace fuel filters regularly
• Drain water separators
• Avoid contaminated fuel sources
• Inspect injection performance when symptoms appear
