The Teflon ring is a crucial seal for the piston in the gearbox clutch drum. Its job is to maintain the oil pressure that clamps the clutch plate pack, thereby engaging a gear or direction of travel. If your machine is "slipping" in gear, loses drive when hot, has a delayed response when shifting direction, or the transmission is overheating, these are classic symptoms of a cracked or worn ring. A damaged ring causes a loss of pressure, which leads to burnt plates and the destruction of the entire clutch pack.

The Teflon and rubber rings on a piston should always be replaced as a complete set. Replacing just one component is ineffective and short-lived.
Working inside the gearbox requires sterile conditions. Ensure that no external contaminants enter the system.
Use special sleeves or sizing bands to correctly compress Teflon rings. Do not use sharp tools that could damage them.
After the repair, fill the gearbox with fresh, dedicated oil, such as HYPTRON, and install a new oil filter (e.g., from REDX).
Answer: Yes, it is a primary suspect. A cracked or worn ring on the piston for that gear's clutch pack will cause a loss of pressure and clutch slip.
Question: Can I reuse the old ring?Answer: Absolutely not. Teflon rings are single-use. They lose their shape and sealing properties upon removal. New ones must always be installed.
Question: What is the main cause of failure for these rings?Answer: The most common causes are contaminated oil (due to an old or faulty filter), gearbox overheating, or mechanical damage during an incorrect installation.
