Piston Ring 40mm x 1.5mm for Husqvarna 41 141 142 Jonsered 2040 CS2040 530 02 99-82

Piston ring for Husqvarna 41, 141 and 142 chainsaws — 40mm x 1.5mm.

Rings wear out long before the piston does. A fresh ring restores lost compression and brings a tired saw back to life, at a fraction of the cost of a full top end rebuild.

This is the same ring supplied in our 40mm piston and cylinder kit (QG14240), available here on its own.

Specifications:

Spec	Detail
Diameter	40mm
Thickness	1.5mm
Quantity	1 ring
Replaces OEM	530 02 99-82
Type	Aftermarket replacement part

Suits these 40mm models as standard:

Make	Models
Husqvarna	41 - 141 - 141LE - 142 - 142E
Jonsered	2040 - CS2040

Also suits these models if already upgraded to 40mm:

Husqvarna 36 - 136 - 137

These saws leave the factory with a 38mm bore, so this ring will not replace a standard one. It suits them only if the saw has been fitted with a 40mm cylinder and piston kit. If you are not sure which you have, measure across the top of the piston before ordering.

What you get:

1x piston ring

Piston, gudgeon pin and circlips are not included. If you need the complete piston, see our Husqvarna piston kits. For a full top end, see our piston and cylinder assembly kits.

Fitting tip:

Two-stroke rings sit over a locating pin in the piston groove that stops the ring rotating into a port. Make sure the ring gap seats either side of that pin before sliding the piston into the cylinder — forcing it in misaligned will break the ring.

WARRANTY OVERVIEW

Jono & Johno offers a 12-month warranty on most products.

We pride ourselves on selling good quality gear and will be fair and prompt in honouring our warranties. If you’re in trouble, we’ll help you out.

WHAT IS COVERED?

The exact warranty coverage depends on two factors:

Whether the fault is due to user error or a manufacturer defect
Whether the fault is minor or major

Minor faults caused by the user

Parts will be supplied for repair at the user's expense.

Minor faults caused by the manufacturer

Customers are expected to perform basic repairs as part of our warranty process.
Jono & Johno will provide replacement parts and instructions for simple repairs, such as installing a recoil starter.
Jono & Johno will determine whether a fault is classified as minor.
If unsure about a repair, contact us, and we’ll assist you.

If preferred (and at our discretion), we may provide replacement parts and contribute to labour costs if you can perform the repair.

Major faults caused by the user

Where possible, parts will be supplied at the user's expense.
If the item cannot be repaired by the user, we offer repairs at our workshop at $80 AUD per hour.
The customer will need to cover return shipping costs for user-related faults.
