The 7700273357 K7M crankshaft is made for Renault vehicles that use the K7M engine. Compatibility may vary by model year and market—verify fitment by matching the engine code (K7M) and part number with your vehicle or consult the seller with your VIN.
This listing describes a high-quality crankshaft built to meet strict standards. If you require OEM-branded confirmation, check the supplier listing or contact the seller to confirm whether it is an original Renault part or an aftermarket unit manufactured to OEM specifications.
The crankshaft is manufactured from high-strength materials suitable for crankshaft applications. Specific alloy composition can vary by manufacturer; request material or certification details from the supplier if you need exact specifications.
Many replacement crankshafts are factory balanced to meet design tolerances, but final dynamic balancing may be required during an engine rebuild. Confirm with the supplier whether this unit is pre-balanced and discuss balancing needs with your machinist.
When installing a crankshaft, it is recommended to replace main and rod bearings, oil seals, crankshaft bolts, and any associated gaskets. Also inspect or replace the timing components and have journals checked for correct tolerances.
Installation requires engine disassembly, precise bearing clearances, torque specifications, and possibly crankshaft balancing. Unless you have engine rebuild experience and proper tools, professional installation by a qualified mechanic or machinist is recommended.
Verify fitment by comparing the part number 7700273357 and engine code K7M to your vehicle's specifications. Provide your VIN or engine code to the seller or consult a Renault parts catalog to confirm compatibility.
Follow standard engine break-in and maintenance: use the correct grade of engine oil, perform timely oil and filter changes, monitor oil pressure, and inspect for unusual noises or vibrations. Ensure the engine is properly balanced and torqued to spec.
Inspect journal surfaces for damage, straightness, and correct oil hole alignment. Check for cracks or casting/forging defects. If any machining or grinding is required, have it performed by a qualified machine shop to the correct undersize and tolerance.
Warranty terms vary by seller or manufacturer. Check the product listing or contact the supplier for specific warranty coverage, duration, and any conditions such as professional installation requirements.
Crankshafts are typically packaged in protective materials to prevent corrosion and damage (plastic wrap, rust inhibitor, foam, secure boxing). Shipping methods depend on the seller—confirm packaging and courier options at purchase.
A high-quality replacement crankshaft restores proper engine function and can support optimal performance if the original was worn or damaged. For performance upgrades beyond stock, discuss specific crankshaft modifications with an engine builder.
Torque specs are not included with the crankshaft listing. Use Renault factory service manuals or a trusted repair database to obtain correct main cap and crankshaft bolt torque values and tightening sequences.
Contact the seller immediately and follow their return/claim process. Keep all packaging and photos of the damage. Most suppliers have return windows and RMA procedures—verify these terms before purchase.
Confirm authenticity by checking the part number against Renault parts catalogs, requesting seller documentation or labeling, and verifying compatibility through your VIN or an authorized Renault dealer.
