Summary: Absolute tightness for KZ10 to R3

The internal cylinder head is the most demanded element of your high engine. Located at the point of contact between the cylinder head dome (insert) and the cylinder, it has the critical role of sealing the combustion chamber.

This seal in Viton High Performance is the standard for the entire line of TM Racing competition engines, including the last born: the TM R3. It must withstand colossal pressures and extreme burned gas temperatures. A seal in perfect condition is the only guarantee of constant motor power and protection against coolant intrusion into the cylinder.

- Why choose the original TM Racing seal?

1. Total compatibility: Designed for KZ10, KZ10B, KZ10C, R1, R2 and New Models TM R3.

2. Specific Viton: Special elastomer capable of maintaining its sealing properties beyond $ 250 ° C. $.

3. Precision adjustment: Its section is calculated to crash exactly the value needed during torque tightening, ensuring the expected chamber volume (SQUI).

4. Standard competition: Part strictly identical to that used by the official TM RACING service official.

💡 Michel's trick

"With the arrival of the R3, thermal constraints are still strong. My Pro Council: Never reuse this seal. Even if he looks clean, once he has undergone a heating cycle and crushing the cylinder head, his shape memory is impaired. The trick: When mounting on your R1, R2 or R3, clean the cylinder groove with a cotton swab and a little solvent. A simple impurity can create a compression leak that you will only feel at the track, when the engine will lose its extension. "

- Mounting & Maintenance Guide

• Preparation: Clean the seal plans with a non-fat solvent.

• Installation: Insert the seal into the cylinder groove. He must fit perfectly without forcing.

• Tightening: Use a torque wrench. The tightening of cylinder head nuts on a TM KZ is generally $ 1.2 $ KGM ($ 12 $ Nm), on the cross and two steps ($ 0.6 $ then $ 1.2 $).

• Frequency: To replace each piston change or whenever you remove the cylinder head.
