Heavy-Duty Full Bearing Assembly
Restore drive and power transfer to your cutting drum with this heavy-duty, full-bearing centrifugal clutch. Designed with a 25.4mm (1 inch) bore, this unit is a direct replacement for our legacy Titan Pro 13HP petrol wood chippers.
At Titan Pro, we don't hold grudges! If you purchased a chipper from another brand that was fitted with a sub-standard clutch, this premium full-bearing assembly is an excellent upgrade for compatible 25.4mm machines, including those manufactured by Hoslinger and Handy.
Important: Measure Before You Order!
For the last 10+ years, Titan Pro chippers have been manufactured using a standard 25mm crankshaft. If you have a newer machine (such as the TP15chip or TP1200), you will likely need our standard 25mm Centrifugal Clutch instead.
Keyway Widths: This 25.4mm clutch is available with either a 4.90mm or 7.00mm keyway slot. Please use a digital vernier caliper to carefully measure your engine's crankshaft diameter and keyway width before selecting your option from the drop-down menu above.
Premium Upgrade
Features a high-quality full-bearing design, making it a reliable upgrade over cheaper cross-brand clutches.
Two Keyway Options
Available in both 4.90mm and 7.00mm keyway variants to match your exact crankshaft specifications.
Free UK Delivery
Fast, free shipping is included to all standard UK postcodes.
Titan Pro Tech Tip: Precision is Everything!
You cannot force a 25mm clutch onto a 25.4mm shaft, and a 25.4mm clutch will dangerously rattle and quickly destroy a 25mm shaft! Always clean your engine's crankshaft with wire wool and use a digital vernier caliper to confirm the exact dimensions of both the bore and the keyway before attempting installation. A dab of anti-seize grease on the shaft during installation will save you a massive headache years down the line!

Centrifugal clutch.
A very good service from Titan pro. The clutch arrived very quickly and is a well built. It should give a lot of years of service I havent had a chance to use it yet but Im sure it will be worth the money.
