Copper cylinder head joint TM KZ10C KZ R1

€2.39
  Tax included
Reference: tm05070.05

This perforated copper washer is a critical piece between the cylinder head dome and the cylinder. It fills two essential functions: ensure a perfect thermal seal under high pressure and allow the preparer to adjust the squish (Piston distance / cylinder head).

  • Copper material: Copper is used for its ability to deform slightly during tightening, ensuring total sealing, as well as for its optimal thermal conductivity.

  • Perforated design: The perforation (detail 6 of the exploded view) allows the passage of the coolant for efficient thermal regulation of the combustion head.

  • Multi-thickness: Available in a wide range of thicknesses to accurately adjust the room volume and compression ratio.

- Installation and preparation consulting

  1. Choice of thickness: The thickness chosen directly influences your value of squish. A too thin seal can cause a shock between the piston and the cylinder head at high speed, while a thick seal decreases compression and performance.

  2. SUISH measurement: Use precision tin wire to measure your squish after installing the puck and tight the cylinder head to the torque.

  3. Tightening to the couple: It is imperative to use a torque wrench to tighten the crosse cylinder heads (usually between 1.0 and 1.2 kgm on these models) to crush the washer in a uniform way.

  4. Single use: Although copper can sometimes be reused after an anneck, it is strongly advised to use a new seal each disassembly to ensure a perfect seal in competition.


💡 Michel's trick

"The dome gasket is your power cursor! The trick: On the motors of the R Series (R1, R2, R3), the accuracy is such that 0.05 mm difference is reached on the engine behavior. My Pro Council: Always check the flatness of your dome before laying your copper washer. If your engine tends to eat water or press pressure in the radiator, it is often this washer (or its tightening) that is involved! "


❓ FAQ SEO (Frequently Asked Questions)

Q: Is this seal compatible with new R2 and R3 models ?

A: Yes, after checking the technical specifications of the TM Racing factory, the cylinder head and the dome sealing system (detail 6) are identical for the engines KZ10C, R1, R2 and R3.

Q: How to know what thickness order ?

A: It depends on the height of your piston with respect to the top of the cylinder. Refer to the mounting data sheet provided by TM or your preparer for the value of Squish target (often located between 0.90 mm and 1.05 mm depending on the categories).

Q: Should we add from the joint dough ?

A: Absolutely not. Copper ensures mechanical crushing sealing. The joint paste could obstruct the perforated cooling ducts in the washer.
