Product Information
Full details
The Ufixt non-genuine idler pulley is an essential replacement component designed for owners of Castelgarden, Honda, Mountfield, Stiga, and Lawnking ride-on mowers who need to restore consistent belt tension and mower deck performance. It serves as a direct, cost-effective substitute for original part numbers 25601558-2, 25601570-0, and V2-5002-740, providing reliable operation for Twin Cut deck systems; however, users must carefully cross-reference the 50mm outside diameter and 39.5mm inside diameter against their existing pulley to ensure a correct fit for their specific mower configuration.

FAQs
Is this a genuine Castelgarden part?
No, this is a high-quality non-genuine replacement part designed to meet or exceed original specifications.
Will this fit my Honda ride-on mower?
It is designed to fit several Honda models, but you must verify that your original part number matches 25601558-2 or that the dimensions are 50mm OD and 39.5mm ID.
Does this pulley include the mounting bolt?
No, this listing is for the pulley only. You should reuse your existing mounting hardware.
How often should I replace this pulley?
It should be replaced whenever you notice excessive noise, physical cracks in the pulley, or if the bearing feels loose or gritty when spun by hand.
Can I use this on a mower that isn't a Twin Cut?
While it is designed for Twin Cut decks, it may fit others provided the outer diameter and shaft size match your machine's requirements.
Troubleshooting
Belt slips immediately after installation
Check that the belt is correctly routed through the pulley groove and confirm the belt itself has not stretched beyond its useful life.
Pulley wobbles during operation
Ensure the mounting bolt is fully tightened and the spacer or washer configuration matches the original setup.

Setup, Compatibility & Care
To install the replacement pulley, ensure the mower engine is off and the spark plug wire is disconnected for safety. Access the cutting deck by either tilting the mower or removing the deck guard according to your manufacturer's manual. Remove the retaining bolt securing the old pulley, swap in the new Ufixt unit, and torque the bolt firmly. It is highly recommended to inspect the drive belt for wear while the pulley is removed, as a new pulley can be damaged quickly by an old, frayed belt. Compatibility is confirmed for Castelgarden TC92, TC102, and TC122 models; always verify the 50mm OD specification if you are using this part on other branded units.
