What the harness screw m8 x 16 does

These two screws carry the entire weight of the machine into the harness. They are larger than anything else on the Zephyr for exactly that reason, and they are the fasteners you least want to find loose.

Signs it needs replacing

Replace them if the drive is damaged, if the thread is stretched or corroded, or as a matter of course whenever the harness is replaced. Check them whenever the machine is serviced — a loose harness screw is a dropped machine waiting to happen.

Installation and fit

Fit both by hand first, then tighten firmly and evenly. Do not use an impact driver, and do not overtighten into the mounting — firm and checked is better than tight and stripped.

Frequently Asked Questions

Should I replace them with a new harness?

Yes. They are pennies and they are the joint carrying the whole machine.

How often should they be checked?

Every service, and any time the harness feels different to wear.

Can I substitute a hardware-store M8?

Length and head form matter here. Use the Tacony part.

Which machines use it?

The Tornado Zephyr TV570-Q03-U only.
