4HK1 Engine Crankshaft Front Oil Seal 8973297800 8-97329780-0 for Excavator 700P 4HF1

Product Details

Product Overview

This high-quality Crankshaft Front Oil Seal is a critical component for maintaining the integrity of your diesel engine’s lubrication system. Identified by the OEM part number 8-97329780-0 (also listed as 8973297800), this seal is specifically designed for the front of the crankshaft on Isuzu 4HK1, 6HK1, and 6HH1 series engines.

Commonly used in heavy-duty excavators and industrial machinery, such as the 700P and 4HF1 models, this genuine oil seal prevents oil leaks from the crankshaft timing cover area. A faulty front seal can lead to significant oil loss, contamination of the engine bay, and potential damage to the timing belt or chain components. This replacement part ensures a precise fit and reliable sealing performance to restore your engine’s efficiency.

Key Features & Benefits

FAQ

Q: How do I confirm this seal fits my 4HK1 engine?
A: The part numbers 8-97329780-0 and 8973297800 are the genuine Isuzu numbers for the front crankshaft seal on 4HK1, 6HK1, and 6HH1 engines. We recommend measuring the inner diameter and outer diameter of your old seal or checking your engine’s parts manual to confirm physical dimensions match before installation.

Q: What are the signs of a failing crankshaft front oil seal?
A: Common indicators include visible oil dripping from the front of the engine behind the harmonic balancer, oil residue on the timing cover or belts, a burning oil smell from the engine bay, and low engine oil levels without external leaks elsewhere. Replacing it promptly can prevent belt damage and oil contamination.

Q: Is professional installation required for this seal?
A: While a skilled mechanic can replace this seal, it requires removing the crankshaft pulley (harmonic balancer) and timing cover. Proper installation is critical to avoid damaging the new seal lip. We recommend using a seal installation tool to press it in evenly and lubricating the seal lip with engine oil before installation to prevent dry start failure.
