FAQ
Q1: What are the signs that my TU26 clutch needs replacement?
A: Common signs include the sprayer pump not turning when the engine is revved, slipping under load (reduced spray pressure despite high RPM), rattling noises at idle, or visible wear on the clutch shoes.
Q2: What is included in the "screw set"?
A: The screw set typically includes the crankshaft retaining bolt (with left-hand or right-hand thread, depending on rotation direction), lock washer, and any cover or drum mounting screws required for installation.
Q3: How do I know if this clutch fits my TU26 engine?
A: Check your engine crankshaft type (tapered vs. straight bore) and verify the thread direction. Most TU26 engines use a specific left-hand thread retaining nut. Also confirm your sprayer model (768 series) compatibility.
