Nylon Washer B017-2500

The nylon washer (part# B017-2500) is a moulded nylon washer used in Tacony-built uprights to space and cushion a fastened joint. It keeps a fastener from bearing directly on the plastic or metal around it, takes up small clearances, and damps the vibration that would otherwise loosen the joint over time.

This is a genuine Tacony OEM part. On the Tornado CK ULW 13/1 it is callout 6 of the factory handle and body assembly sheet.

Compatible Models for the Nylon Washer B017-2500

• Tornado: TV280-W12-U (CK ULW 13/1)
• CleanMax: Zoom ZM-500, Zoom ZM-700

Those are the machines confirmed for this washer. Tacony lists it under a generic nylon washer description rather than tying it to one model, so it turns up in several assemblies across the ultra-lightweight range. If your machine is not on the list, call with the model number and we will check the part list before you order.

What the nylon washer does

Its work is quiet but real. In a fastened joint the washer spreads the clamping load over a wider area than the fastener head, which matters most where the material underneath is a moulding rather than metal. It also gives the joint a small amount of compliance, so that vibration is absorbed rather than being transmitted straight into the fastener and working it loose.

Signs the nylon washer needs replacing

Nylon ages. Replace the washer if it has yellowed and gone brittle, split at the bore, flattened out of shape, or if it falls apart when the joint is disturbed. New play or a rattle around a joint you have opened before is a good reason to fit a new washer rather than reuse the old one, since a washer that has been clamped for years will not spring back.

Installation and fit

Unplug the machine before working on it. Note where the washer sits in the stack before you take the joint apart — which side of the bracket, and whether anything else shares the fastener — and rebuild in the same order. Tighten firmly but do not crush the washer: over-tightening a nylon washer defeats the cushioning it is there to provide.

Frequently Asked Questions

What does the nylon washer B017-2500 do?

It is a moulded nylon spacer that sits in a fastened joint to take up clearance, cushion the joint and keep the fastener from biting into the plastic or metal around it. Nylon is used rather than steel because it is quieter, does not corrode and will not chew into a moulding.

Which machines use the nylon washer B017-2500?

It is confirmed on the Tornado CK ULW 13/1 (model TV280-W12-U), where it is callout 6 of the factory handle and body assembly, and on the CleanMax Zoom ZM-500 and ZM-700. Tacony catalogues it as a generic nylon washer, so it appears in more than one place across the ultra-lightweight range.

How do I know if mine needs replacing?

Look for a washer that has gone brittle, cracked, flattened or elongated at the bore, or one that no longer takes up the clearance it should. A joint that has developed a rattle or a little play after a previous repair is the usual sign that the washer under it has given up.

Can I substitute a steel washer?

It is not a good idea. Nylon is chosen for the cushioning and for the fact that it will not gall or cut into the surrounding plastic. A steel washer of the same size will transmit vibration and can damage the moulding it is clamped against.
