FAQ

Q1: Are these bearings suitable for a Perkins N844 engine rebuild?

A: Yes, this set is specifically designed for the Perkins N844 engine. It includes the standard-size main bearings (198586140) and connecting rod bearings (U5ME0011) required for a standard rebuild. Always check your crankshaft journal for wear; if it is out of tolerance, you may require undersized bearings.

Q2: What is the correct installation clearance for these bearings?

A: The recommended oil clearance for the main bearings is 0.040-0.089 mm (0.0016-0.0035 inches), and for the connecting rod bearings, it is 0.025-0.076 mm (0.0010-0.0030 inches). Always use plastigauge during installation and lubricate the bearings with assembly lube. Torque main bearing caps to 95 Nm and connecting rod bolts to 49 Nm for the N844 engine.

Q3: Can I use these bearings in a Perkins N844T (turbo) engine?

A: Yes, these standard bearings are compatible with both naturally aspirated (N844) and turbocharged (N844T) versions of the engine. However, for high-performance or heavily modified turbo applications, we recommend consulting our technical team to verify if a higher-performance bearing grade is required for extreme loads.
