This sheet covers the battery mount (part# K50321850) that carries the 36V pack, the latch and release mechanism that holds it, the complete brush height adjustment train, and the on/off switch and contact display in the housing face. It is the assembly most service work on a Tempest touches, because it contains both the parts an operator handles every shift and the parts that set how well the machine actually sweeps. Twin City Vacuum has been selling and servicing Tornado equipment since 1956. Call 763-535-0770 or stop by 5415 West Broadway, Crystal, MN 55428.
Callout 50 appears in six places on this diagram and callout 210 in two — the same part number used at several points on the assembly. Each dot links to the same product page.
Frequently Asked Questions
What does the battery housing do on the Tornado Tempest?
It is the structural centre of the machine’s control end. The battery mount (part# K50321850) carries the 36V pack and the roller height adjustment, and the latch, release button, adjustment knob train, on/off switch and contact display all fit into it.
My Tempest battery will not stay latched — which part do I need?
Start with the battery latch (part# K50369480) and its spring (part# K63302640). If the release button stays pressed in, the release spring (part# K63301600) is the cause. If the pack rocks in a housing that is visibly cracked, the battery mount itself is the fault.
The brush height setting will not hold — where do I look?
Work down the adjustment train in order: the knob (part# K53224590), its bushing (part# K51120430), the twisting bolt (part# K51053320), the lever (part# K51297940) and the square bearing (part# K50321900). Play in the knob points at the bushing; play in everything at once points at the knob bracket (part# K50979610).
Why do some parts on this page have no price?
Seven of the twenty-five parts on this assembly are not currently listed in the Tornado dealer catalogue. Rather than publish an estimate we have left them as call-for-price. Ring 763-535-0770 and we will source and quote them.
Do these parts fit the Tornado Strike or Zephyr?
Almost none of them. The battery housing is specific to the Tempest TV400-W26-U. The two exceptions on this sheet are the shared fasteners — the M5 x 20 screw (part# K73031080) and the M4 x 12 screw (part# K73031060), both of which are used across a wide range of Tornado machines.
