- The trick in Michel (the corner of the expert)
* "Hi the mechanos! The nut n ° 20 of the exploded view, it is the m8 nut with 12 mm base that plates your cylinder R3 against the bottom-engine and closes your cylinder head. As the cylinder heats and undergoes a huge thrust each Explosion, these nuts work enormously in extension.
My stand trick for a perfect and deformation cylinder tightening: cross tightening at torque wrench !
When you go up your cylinder or your cylinder head with these new M8 nuts, never tighten them blind with a flat key to PIF. First approach the 4 hand nuts, then apply the tightening torque advocated by TM Kart (usually around 22 to 24 nm) in stroke (in x) and in 2 or 3 progressive passes (for example 12 nm, 18 nm then 24 nm).
This ensures that the base joint (marker 16) crashes 100% homogeneously and that your Nicasil shirt is not twisting. A set of new base nuts and a tightening to the torque is the key to preserve your high-engine! "*

- SEO FAQ (Frequently Asked Questions)
Q: Which component of the kz-r3 exploded view corresponds exactly this nut n ° 20 ?
A: On the TM Kart Technique Plate (Tavola 1 / Cylinder and Head), the Landmark no. 20 designates the 12 mm (CH 12) m8 (CH 12) nut nuts that come to screw on the studs (N ° 21) for blocking the cylinder (# 12) on the bottom-motor.
Q: Does this nut require an extra washer during assembly ?
A: Not. The specificity of this original nut is to directly integrate its own enlarged base / flange machined under the body of the nut. She plays the role of washer by perfectly spreading the clamping stress on the aluminum flange of the cylinder.
Q: Does this m8 CH12 nut suitable for previous generations of TM engines ?
A: Yes I do. The CH12 Footprint M8 / Cylinder Hollar nuts are the historic standard of TM Kart. They adapt perfectly on the KZ10, KZ10B, KZ10C, KZ-R1, KZ-R2 and KZ-R3 blocks perfectly.
