Perkins 1106 C7.1 Diesel T417566 Crankshaft Bearing Set for Excavator Engine Parts

This T417566 crankshaft main bearing set is precision-engineered for Perkins 1106 and C7.1 series diesel engines widely used in excavators and heavy-duty construction machinery. Each bearing is manufactured to meet or exceed OEM specifications, providing critical support for the crankshaft under high-load operating conditions.

• OEM Specification Compliance: Manufactured to precise dimensional tolerances matching original Perkins T417566 crankshaft bearings, ensuring correct oil clearance and reliable engine operation.
• Steel-Backed Babbitt Construction: Features a robust steel backing for structural integrity with a premium Babbitt alloy lining that provides excellent embeddability and conformability for crankshaft journal surfaces.
• High Load-Bearing Capacity: Engineered to withstand the extreme combustion pressures and rotational forces generated by Perkins 1106 and C7.6 diesel engines during heavy excavator operations.
• Optimized Oil Grooving: Precision-machined oil grooves and spreader channels ensure consistent lubrication distribution across the bearing surface, reducing friction and operating temperatures.
• Superior Wear Resistance: The Babbitt alloy overlay offers outstanding anti-seizure properties and debris embeddability, protecting the crankshaft journals from scoring during contaminated oil events.

This crankshaft bearing set fits Perkins 1106 and C7.1 diesel engines commonly found in CAT excavators, wheel loaders, backhoe loaders, and other heavy equipment platforms. It is suitable for both complete engine overhaul and crankshaft bearing replacement projects.

1. Inspect crankshaft journals for wear, scoring, and out-of-round condition before ordering replacement bearings
2. Measure crankshaft journal diameters with a micrometer and verify against engine service manual specifications
3. Clean all oil galleries and bearing saddles thoroughly before installation
4. Apply clean engine assembly lubricant to bearing surfaces before installing the crankshaft
5. Check main bearing oil clearance with Plastigage after torqueing main bearing caps
6. Follow Perkins engine manual torque specifications and tightening sequences for main bearing cap bolts

Each bearing shell is individually coated with anti-corrosion preservative oil and sealed in moisture-resistant protective wrapping. Complete sets are packed in export-grade double-wall cartons with foam-lined compartments to prevent bearing contact and surface damage during transit.
