VALVE GUIDE-TRID
Valve guide for Triumph triple engines, PN 70-6420/002 (also listed as 70-0344).
This is a valve guide for the Triumph triple-cylinder engines, listed under part number 70-6420/002, also found in older records as 70-0344. The "/002" suffix in the number typically points to a size or fit variant, so if you're matching one to a head that's already been machined, it pays to check with us before you order.

A valve guide sits in the cylinder head and keeps the valve stem running true as it opens and closes, so wear here shows up as sloppy valve action and can affect how the engine seals up top. We don't have much more detail on file for this specific listing beyond what's above, so if you're rebuilding a triple head, give us a call and we'll help confirm which guide you actually need.
