Tornado Tempest Hopper Spring K53321850

The Tornado Tempest hopper spring (part# K53321850) returns the hopper release lever (part# K50321830) and keeps the debris container latched on the TV400-W26-U cordless sweeper, with two fitted. Tacony lists it as Spring, Hopper. The Tempest catalogues seven springs under that single word and they are not interchangeable.

What this spring actually guarantees is that the hopper is latched by default rather than by the operator remembering to latch it. Release the lever and the spring closes the latch; there is no separate action to perform. When the spring weakens, that default quietly inverts — the hopper stays wherever the lever left it, and eventually one gets carried out with the machine still moving.

Compatible Models for the Hopper Spring

• Tornado Tempest Wide-Area Cordless Carpet Vacuum Sweeper — Model TV400-W26-U

Symptoms that point to the hopper spring

• The release lever does not return to its rest position on its own.
• The hopper can be lifted out without touching the lever.
• The hopper rattles or shifts while the machine is running.
• The spring is visibly stretched, kinked or broken.
• A new release lever was fitted and the latch still does not hold.

The second symptom is the one to act on immediately. A hopper that is not positively latched can come out during use, which on a machine sweeping at working speed makes a mess at best.

Fitting notes

Remove the battery pack before starting. Note how the old spring is hooked at both ends before removing it — fitted the wrong way round it will hold the lever open rather than closed, which is worse than no spring at all. Replace both springs together; they age at the same rate. After fitting, check the lever returns briskly on its own and the hopper latches positively before returning the machine to service.

Frequently Asked Questions

What does the hopper spring do on the Tornado Tempest?

It returns the hopper release lever and keeps the debris container latched by default, so the hopper is held securely without the operator having to do anything extra.

How do I know if my hopper spring needs replacing?

If the release lever does not return on its own, if the hopper lifts out without touching the lever, or if the hopper rattles while the machine runs. If a new lever did not fix the latch, the spring is the cause.
