TAPPET ADJ,MUSHROOM SET 6 - 1968-72 T150 (shorter style for longer valves) after 72 use 71-3358M
Set of six mushroom-style tappet adjusters (shorter style, for longer valves) for the 1968-72 T150 Trident, PN 70-8783M.
This is a set of six mushroom-style tappet adjusters for the T150 Trident triple, listed in our records as the shorter style meant to work with longer valves. The part number 70-8783M covers the run of these used from 1968 through 1972. If you're working on a Trident from that span, this is the tappet adjuster set the parts book calls for.

Starting in 1973 the factory moved to a different tappet adjuster, 71-3358M, so if your engine falls after that changeover this earlier shorter-style set isn't the one to order. The catalog also lists an alternate reference number, 99-9902, for the same set.
Because these mushroom adjusters are sized to work with longer valves specific to this engine and era, it's worth double-checking which valve length and tappet style your Trident actually has before ordering, since getting the wrong style for the valve length on hand won't seat correctly.
