Step-by-Step Guide

Step 1: Preparation

Start by preparing your work area. Make sure your engine is cool and turn off the ignition. Disconnect the battery to prevent any accidental starting of the engine.

Step 2: Raise the Vehicle

Use a jack to lift the front of your vehicle and secure it with jack stands. This will provide you the necessary access to the undercarriage of your engine.

Locate the front pulley on your diesel engine. Use a socket wrench to loosen the bolts holding it in place. Once loosened, carefully remove the front pulley and set it aside.

Inspect the counterbalance for any signs of damage or wear. If necessary, replace it with a new one. Ensure proper alignment and torque the bolts according to manufacturer specifications.

Using a seal puller, gently remove the old crank seal. Clean the area thoroughly and apply a small amount of penetrating oil to ease installation. Carefully insert the new crank seal, ensuring it is properly seated and aligned.

Step 6: Reinstall the Front Pulley

Place the replacement front pulley onto the crankshaft. Tighten the bolts securely using a torque wrench, following the recommended torque values provided by the manufacturer.

Step 7: Lower the Vehicle and Test

Remove the jack stands and lower your vehicle. Reconnect the battery and start the engine. Monitor for any unusual noises or vibrations to ensure the replacement was successful.
