FAQ

Q1: How do I confirm this 4D34 crankshaft sleeve fits my engine?
A: Verify your engine model code (stamped on the engine block nameplate) matches “4D34”. For best results, remove your old sleeve and measure the outer diameter and length against the OEM specifications. If you have the original part number (e.g., ME015876), cross-reference it with our listing. We recommend consulting your engine service manual for exact fitment requirements.

Q2: What is the installation procedure for this sleeve?
A: Installation typically requires a press tool or sleeve driver to avoid distortion. The sleeve must be installed clean and dry (or with light lubricant as per manual specs) into the engine block bore. Ensure the rear main seal lip is properly lubricated during assembly. We recommend professional installation by a qualified diesel mechanic. Refer to your Mitsubishi 4D34 service manual for torque and clearance specifications.

Q3: How can I prevent premature wear on the new crankshaft sleeve?
A: Ensure the engine oil system is clean and free of debris. Use high-quality diesel engine oil with the correct viscosity (typically 15W-40 for most applications). Replace the rear main seal simultaneously with the sleeve. Regular oil changes and monitoring for crankshaft end-play will extend sleeve life. If the crankshaft shows scoring or out-of-round conditions, it may need regrinding before new sleeve installation.
