STATOR STUD LONG 4.25AL
Long stator mounting stud for the primary chaincase on Triumph 650 unit twins, also listed as E4536.
70-4536 is the long stator stud that mounts the alternator stator plate inside the primary chaincase. It's a threaded stud, not a bolt, so it stays put in the case while the stator and its retaining nuts go on and off around it. The catalog also knows this part under its older code, E4536, which is the same physical stud carried forward under the current numbering.

This one turns up in the CHAINCASE AND CHAINS section of the parts books, alongside its shorter counterpart (70-4537) which handles the other stator mounting position. Between the two, they're what lets the stator sit correctly against the primary case wall so the alternator can do its job.
Owners doing chaincase work or chasing a bent stud or chewed-up nut threads from years of servicing often replace these as a pair with the shorter stud and the nuts that go with them, since they're all subject to the same wear. Catalog appearances put this stud on unit-650 twins from the mid-1960s; check your own parts book listing before ordering to be sure it's the right length for your stator position.
