Installation: this is a press-fit seal. Caterpillar specifies installer tool 1U-7430 for the seal. Inspect the crankshaft wear sleeve when the seal is out — a grooved or scored sleeve will destroy a new seal, and the sleeve installs with tool 5P-6208.

Match the seal dimensions against the seal you are removing before ordering.
