Clutch Hydraulics
About Clutch Hydraulics
A hydraulic clutch replaces the cable with fluid. A master cylinder at the lever pushes fluid to a slave cylinder that releases the clutch. Riders switch to hydraulics for a lighter, more consistent lever feel, or replace a system that has leaked or lost pressure.
This category has a single listing, a Hymec clutch system from Magura. Fit matters with a hydraulic conversion, because the lever, the lines and the release have to suit your engine, so check the listing for the machines it covers and follow the maker's instructions for installation. Most hydraulic systems need bleeding after fitting, and the fluid must be the one the maker specifies.
The brand here is Magura. If your machine uses a cable instead, see Clutch Cables, and for the rest of the clutch see Clutch Plates & Discs and Complete Clutches & Kits. All of them are part of Clutch Parts & Kits. Pick your machine in the Ride Finder at the top of the page to see what is made for it.
FAQs on UTV and ATV hydraulic clutches
How does a hydraulic clutch differ from a cable clutch?
A cable clutch pulls a steel cable from the lever to the release arm. A hydraulic clutch moves fluid through a line from a master cylinder to a slave cylinder. Hydraulic systems often feel lighter and need little adjustment, but they must be kept free of air and leaks.
Does a hydraulic clutch need free play adjustment?
Many systems adjust for wear through fluid and need little or no free play at the lever, but the setup varies. Check the maker's instructions for your system and follow the owner's manual for your machine.
Which fluid does a hydraulic clutch use?
The one the maker specifies. Some systems use DOT brake fluid and others use mineral oil, and mixing them can damage the seals. Never guess, and do not top off with a different fluid.
How do I bleed a hydraulic clutch?
Follow the maker's instructions. In general you fill the reservoir, work the lever, open the bleeder to release air and fluid, close it and repeat until the lever feels firm. Air in the system gives a soft, spongy lever.
