It sits in the \u003cstrong\u003e330426\u003c\/strong\u003e family alongside the \u003cstrong\u003e330426-401\u003c\/strong\u003e, \u003cstrong\u003e330426-405\u003c\/strong\u003e, \u003cstrong\u003e330426-406\u003c\/strong\u003e, \u003cstrong\u003e330426-407\u003c\/strong\u003e and \u003cstrong\u003e330426-408\u003c\/strong\u003e. It is an inexpensive part for the job it does: it \u003cstrong\u003elocates the blower motor\u003c\/strong\u003e, supports it, and \u003cstrong\u003eisolates its vibration\u003c\/strong\u003e so the unit runs quietly.\u003c\/p\u003e\n\n\u003cp\u003eBecause the \u003cstrong\u003e330426\u003c\/strong\u003e family is a run of separate dash numbers, the \u003cstrong\u003e330426-403\u003c\/strong\u003e should be matched by the \u003cstrong\u003enumber stamped on the old arm\u003c\/strong\u003e, not by looks. The \u003cstrong\u003earm length, bend angle, mounting holes and grommet\u003c\/strong\u003e differ from one dash number to the next, and an arm that is close but not right can leave the \u003cstrong\u003emotor\u003c\/strong\u003e off-center, \u003cstrong\u003ecock the shaft\u003c\/strong\u003e against the \u003cstrong\u003eblower wheel\u003c\/strong\u003e, or place the \u003cstrong\u003egrommet\u003c\/strong\u003e under uneven load.

A \u003cstrong\u003ebent arm\u003c\/strong\u003e or \u003cstrong\u003efatigued bend\u003c\/strong\u003e does the same damage in a different way by letting the \u003cstrong\u003emotor sag\u003c\/strong\u003e.
