This OEM-spec valve guide (part #140-1614/1401614) is engineered to deliver reliable valve operation in Ford's legendary 2N, 8N, and 9N tractor engines. Designed as an exact replacement for the original component, it ensures proper valve alignment and longevity in agricultural applications.

✔ Key Features & Benefits

1. Authentic OEM Replacement

• Precision duplicate of Ford's original part #140-1614

• Manufactured to exact 120ci (2.0L) L-head engine specifications

• Maintains correct 5/16" valve stem clearance for perfect fitment

2. Durable Cast Iron Construction

• High-grade iron alloy withstands continuous tractor operation

• Machined to precise 0.342" inner diameter for proper oil control

• Heat-treated for extended service life in dusty farm conditions

3. Enhanced Engine Performance

• Maintains proper valve-to-seat alignment

• Reduces oil consumption by controlling lubrication

• Prevents valve stem wear and scoring

• Extends valve service intervals

✔ Critical Replacement Indicators

1. Visible Wear Symptoms

• Excessive valve stem play (beyond 0.005" clearance)

• Noticeable oil consumption through guides

• Blue exhaust smoke during operation

• Irregular engine compression

2. Operational Issues

• Difficult starting due to poor valve seating

• Loss of engine power under load

• Increased valve train noise

• Oil fouling of spark plugs

✔ Technical Specifications

1. Precision Manufacturing

• Machined to ±0.0005" tolerance for consistent fit

• Surface finish optimized for oil retention

• Length precisely matched to original Ford dimensions

2. Durability Features

• Resists wear from agricultural dust and debris

• Maintains dimensional stability in temperature extremes

• Special groove design for positive oil control

✔ Installation Requirements

1. Professional Installation

• Requires proper reaming to achieve specified fit

• Needs guide height adjustment for proper spring operation

• Should be installed with correct driver tools

2. Complementary Services

• Valve stems should be measured for proper clearance

• Recommended to replace valves when installing new guides

• Essential to check pushrod alignment after installation

Compatible Applications:

• Ford 2N tractors (1942-1947)

• Ford 8N tractors (1947-1952)

• Ford 9N tractors (1939-1942)

• Other applications using 120ci L-head engines

Why This Valve Guide Stands Out:

1. Historical Accuracy - Maintains original Ford engineering specifications

2. Farm-Tested Durability - Proven in decades of agricultural use

3. Oil Management - Proper clearance prevents excessive oil consumption

4. Vibration Resistance - Withstands rough tractor operation

Package Includes:

• (1) OEM-quality valve guide (140-1614/1401614)

• Protective packaging to prevent damage

• Basic installation guidelines

Important Considerations:

• Verify tractor model and engine type before ordering

• Professional installation recommended for best results

• Ideal to replace all guides during engine overhaul

• Requires proper break-in period
