1KD 2KD 1KZ Main Bearing & Connecting Rod Bearing Set 11704-30020 13204-30020 for Toyota Diesel

Product Details

Product Overview

This premium engine bearing set is specifically designed for the Toyota 1KD, 2KD, and 1KZ diesel engine platforms. The set includes both main bearings (OEM 11704-30020) and connecting rod bearings (OEM 13204-30020), providing a complete solution for engine rebuilds or overhauls. Manufactured to OEM size specifications, these bearings are engineered to restore the precise clearances required for optimal oil film thickness and crankshaft support.

Commonly used in a wide range of heavy-duty applications including forklifts, excavators, bulldozers, trucks, and buses, this bearing set is a critical component for maintaining engine reliability under high load and high temperature conditions. The bearings are sourced from, a reputable manufacturer based in Guangdong, China, with a focus on aftermarket quality that meets or exceeds OEM standards.

Key Features & Benefits

• Precision Fit: Machined to exact OEM tolerances (11704-30020 & 13204-30020) to ensure proper oil clearance and prevent bearing seizure or spin.
• Durable Material Composition: Manufactured from high-strength steel backing with a lead-copper overlay for excellent fatigue resistance and embedability of contaminants.
• Complete Set: Includes both main bearings and connecting rod bearings in one package, simplifying ordering and ensuring component compatibility.
• High Load Capacity: Engineered for turbocharged diesel engines like the 1KD-FTV and 2KD-FTV, which produce high cylinder pressures and require robust bearing support.
• Corrosion Protection: Treated with anti-corrosion coating to protect the bearing surface during storage and transportation.
• Verified Dimensions: Each batch is subject to outgoing inspection with video documentation available, confirming dimensional accuracy.

Technical Specifications

OEM Cross-Reference

This bearing set directly replaces the following original Toyota part numbers:

FAQ

Q1: Are these bearings suitable for both standard and undersize crankshafts?
A1: This bearing set is manufactured to OEM standard size specifications. It is intended for use with crankshaft journals that are within factory tolerances. If your crankshaft has been ground to an undersize (e.g., 0.25mm or 0.50mm), you will need undersize bearings. Please measure your crankshaft journals or consult your engine rebuild manual before ordering.

Q2: Can I install these bearings without plastigauge?
A2: While these bearings are precision-machined, we strongly recommend using plastigauge during installation to verify oil clearance. The 1KD and 2KD engines are sensitive to bearing clearances; incorrect clearance can lead to low oil pressure or bearing failure. Target clearance should be between 0.030mm and 0.060mm for main bearings and 0.025mm to 0.055mm for rod bearings.

Q3: What is the difference between the 1KD and 2KD bearing sets?
A3: The main bearings (11704-30020) and connecting rod bearings (13204-30020) are physically identical for both the 1KD and 2KD engines. Both engines share the same crankshaft journal dimensions. The 1KZ engine also uses the same bearing specifications. This set is therefore a direct cross-fit for all three engine models. However, always double-check your existing bearing part number for absolute confirmation.
