FAQ

Q: Is this crankshaft a direct fit for my Perkins 403D-15 engine?
A: Yes, this crankshaft is manufactured to OEM specifications for the Perkins 403D-15 and 403C-15 engines. It is a direct replacement for part numbers 115256950 and 115256580. However, we recommend cross-referencing your old part number and engine serial number to confirm 100% compatibility before installation.

Q: What maintenance should be performed during installation?
A: During installation, it is critical to use new main bearing and connecting rod bearing shells. Always lubricate the journals with clean engine oil before assembly. Torque all bolts to the manufacturer’s specifications and ensure the crankshaft rotates freely without binding. We recommend replacing the rear main seal and front oil seal at the same time to prevent future oil leaks.
