The O-ring seals are added to prevent the terminal assembly clip, should it fail, from falling into the spark plug well and into the combustion chamber during spark plug replacement.
169-4290 Terminal Assembly (1). 8C-3076 O-Ring Seals (2).Adaptable To: Two 8C-3076 O-Ring Seals (2) are now included on the 169-4290 Terminal Assembly (1) for the EIS 165-1589 Transformer Group. As noted in the Reference Article a 169-4295 Extension, 169-4292 Spacer and 169-4290 Terminal Assembly must be used together in the 165-1589 Transformer Group. If the engine is operating with a 169-4290 Terminal Assembly that does not have the two 8C-3076 O-Ring Seals, please check the terminal assembly for a broken clip before removing the spark plug. If the clip is broken and has fallen into the spark plug well, remove the clip pieces before removing the spark plug. If the clip was broken, install a new 169-4290 Terminal Assembly before installing the 165-1589 Transformer Group.
