FAQ
Q: How do I confirm this clutch housing fits my brushcutter?
A:Check your machine model number and measure your drive tube diameter (28mm). This housing fits CG430, CG520, BC430, BC520, TL43, TL52, 40-5, 44-5, and compatible 43–52cc brushcutters. For 43cc engines, the 1E40F-5 is standard; for 52cc, the 1E44F-5 is used. The 7T option is also available for compatible models.
Q: What are the symptoms that indicate the clutch housing needs replacing?
A: Common symptoms include the cutting head not engaging when throttled, slipping under load, the head spinning at idle, unusual noise from the clutch area, or visible heat damage or scoring on the housing. If these occur, the clutch drum may be worn or warped.
Q: What is the difference between 7T and 9T clutch housings?
A: The "T" refers to the number of splines (teeth) on the drive shaft. The 7T and 9T configurations fit different drive shafts. The CG430/CG520 platform typically uses 9T, but 7T options are also available for compatible models. Always match your existing spline configuration.
