Fitment gate — Caterpillar revised the 3406 front structure gaskets many times across the engine's production run, and this set supersedes a long list of earlier numbers. Provide your engine serial number with your order if you are unsure.
Installation note — replace all front structure gaskets and O-rings whenever the front cover comes off. Reusing individual gaskets from an older set is a common source of oil leaks after front cover work.
Common interchanges: 8C-4457, 6V-9222, 6V-9907, 189-5136, 117-7096
Conclusion
This is the FP Diesel front structure gasket set for the Caterpillar 3406B and 3406C, covering the full front end in eleven pieces including the automatic timing advance cover gasket. It supersedes a long list of earlier Caterpillar front gasket numbers. Provide your engine serial number if you are unsure which set your build takes.
