8-piece bronze valve guide set for Triumph TR2, TR3 and early TR4; converts 3/8" exhaust valve stems to 5/16".
TT1019A is an 8-piece manganese-silicon bronze valve guide set for four-cylinder Triumph TR2, TR3 and early TR4 engines through engine number CT21470E. The set converts the earlier 3/8" exhaust valve stem arrangement to the later 5/16" valve stem size.
Application / fitment
- Triumph TR2 — four-cylinder engine
- Triumph TR3 / TR3A / TR3B — four-cylinder engine
- Triumph TR4 — through engine number CT21470E
The cylinder-head change occurred from engine number CT21471E during 1963; later TR4 and TR4A engines use a different guide set. On older Triumph engines always verify the engine/head number and the actual valve-stem diameter because cylinder heads may have been replaced during previous repairs.
