Triumph Unit 500/350 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 2.5mm allen hex to adjust, and are supplied in sets with nuts.

The 26 tpi CEI thread will fit all unit 500 and 350 from 1958-1974. Triumph part number 70-3223.

These adjusters can be installed and removed without removing the rocker boxes  from the engine.
