- 3 piece tappet adjuster set, including tappet pad, outer adjuster and full width locknut - Fits all SOHC rocker arms. - A very popular item, as these are one of the main consumables of this engine. Price is per Each (i.e. 2 required per cambox)
We have been making these for over 10 years and have sold very many - they are CNC made just as per the originals and are a clever design.
The outer threaded collar has slots and screws into the rocker arms. The inner tappet shaft has a taper that corresponds to a similar taper on the inside of the collar. To adjust the tappet clearance - undo the top locknut, adjust the outer collar using a spanner to set the correct tappet adjustment, then re-tighten the locknut, which locks the two tapers again.
Note: it is often a good idea to loosen the locknut, then give the tappet a vertical 'tap' with a rawhide mallet first, before trying to adjust, this helps 'break' the taper lock on the innder tappet shaft first and makes adjustment easier.
