International main seal install 345 cid?

To install a main seal on a 345 cubic inch International engine, first ensure the engine is clean and free of debris. Remove the oil pan and any necessary components to access the main seal area. Carefully pry out the old seal and clean the sealing surface before installing the new seal, making sure it is properly seated. Reassemble the components in reverse order, ensuring all bolts are torqued to manufacturer specifications.
