CRANKCASES
Triumph crankcases (bottom end main casting), catalog entry 71-2421.
PN · 71-2421
71-2421 is the crankcases listing for the engine bottom end, cataloged under Triumph's own numbering with the E12421 form as its alternate reference. The crankcases are the main casting that holds the crankshaft, the timing gear, and the bottom half of the engine together, so this entry covers the core housing rather than a small hardware item.
