TAPPET ADJUSTER SQ ADJ HD
Square-head tappet adjuster for the Triumph twin engine top end, used to set valve clearance at the rocker.
This is the square-adjuster style tappet adjuster for Triumph pushrod engines, the part that sits at the top of the pushrod where it meets the rocker, letting you set valve clearance. It shows up across a long run of cylinder head and block figures in our books, from the 6T and T110 through the TR6, T120, and T140V, and on into the TR7RV, so it's a part that stuck around on the Triumph twin engine top end for a long stretch of production.

You'll also see it cross-referenced under E1513 and I105 in older parts books - same physical piece, just a different number depending on which edition you're holding. It works together with its locknut to hold whatever gap you've set at the rocker tip, and it's the kind of small part that's worth having a spare of on the bench since it's easy to lose track of when you're doing a valve clearance check.
