How do these bearings help during engine rebuilds or repairs?

Installing fresh main and rod bearings restores correct crankshaft clearance and helps ensure consistent oil film between journal surfaces. That stability supports accurate oil pressure and reduces risk of premature wear during engine reassembly.

• Restores manufacturer-specified clearances for crankshaft journals.
• Works with standard assembly procedures and torque specifications.
• Supplied as a matched set for mains and rods to simplify rebuilds.

What quality checks and warranty coverage come with the set?

The bearings are inspected multiple times under JANLESGMGO’s quality control routines before shipment. The product includes a one-year warranty and customer support to help verify fitment or handle post-purchase questions.

• Multiple inspection steps during production and pre-shipment testing.
• Comprehensive pre-sales help to confirm correct part numbers and photos.
• One-year warranty and responsive after-sales support within 24 hours.

Which installation notes or precautions should a mechanic follow?

Accurate measurement, proper lubrication and correct installation torque are essential when fitting bearings. Always compare the supplied parts to the original bearings and the part photos to avoid mistakes.

• Verify part numbers and photos against the original bearings before installing.
• Use assembly lube and follow OEM torque and bearing clearance procedures.
• Inspect crankshaft journals for scoring or out-of-spec dimensions prior to installation.
