Valve guide (cast iron)
Cast iron valve guide for the T100S/T100C single-carburetor cylinder head, PN 71-0229 (also listed as E10229).
This is a cast iron valve guide, listed in the catalog as part number 71-0229 with the older alias E10229. It shows up in the cylinder block and head sections for the T100S and T100C single-carburetor engines, so it lives in the cylinder head where it seats and guides the valve stem as the valve opens and closes.

A valve guide's job is straightforward: it keeps the valve stem running true so the valve seats correctly every time and doesn't wobble around under heat and load. Being cast iron, it also gives the valve stem a wear surface that's tougher than the aluminum head casting itself.
Our catalog record ties this one to the T100S/T100C single-carb cylinder head figures from the years shown. If you're working on a different Tiger 100 or Triumph single variant, check your own parts book or give us a call before ordering to make sure the guide matches your head casting.
