Rear main seal installer

Worked as needed. Came with 1/2"-20 retaining bolts, need 12mm-1.25 for 2019 6.7 ISB.

This is an exceptional tool!

I’m really satisfied with it because the installer guarantees that the new rear crankshaft seal is correctly positioned and securely fitted, which is crucial for preventing oil leaks and ensuring engine integrity.
