Triumph standard CEI tappet adjuster set
Replace your worn out valve adjusters with this set of English made tappet adjusters. Unlike most on the market today, these are heat treated on the face only, (not induction hardened which leaves the first few threads hardened also).
They are copper plated, as the copper plating protects the threads from embrittlement during heat treatment. They have a 3mm allen hex to adjust, and are supplied in sets with nuts.
The 26 tpi CEI thread will fit all pre unit 500 and 650, as well as unit 650 and 750 engines to 1978. Triumph part number 70-1513 and will also work for BSA part number 67-0056.
These adjusters can be installed and removed without removing the rocker boxes from the engine.
