- The trick in Michel (the corner of the expert)
* "Hi the enthusiasts of the KZ! The standard original cylinder on a TM R3, it is a real piece of Swiss watchmaking. The factory nicasil coating is of a remarkable quality, but for that it outsources its cavalry and lasts for a long time, the assembly request Absolute rigor.
My essential mechanical trick for replacing a KZ-R3 cylinder: the pairing of the piston and the break-in in good standing !
When you install a standard new cylinder, never put your old piston or a piston taken at random. Measure the exact bore of your new cylinder (often delivered in original dimension a) and choose a TM original piston with the operating game recommended by the manufacturer (usually around 0.08 mm to 0.09 mm playing skirt / shirt according to your preparation preferences).
Second Vital Point: bROGING !
Even with nicasil new treatment, make 2 gradual break-in sessions: a first 10-minute session on trolley / track without exceeding mid-speed to mount the set in temperature and control the absence of water leaks, then a session in progressive track with a gradual load with a mix. Slightly richer in oil (4%). A well-applied and prowling cylinder in the rules, it's constant handle-handed watts insurance! "*
- Replacement & Mounting Guide: Step by Step
1.Demontage of the old high-engine:5 min.Drain the cooling circuit of your TM KZ-R3 engine. Remove the exhaust pot, the cylinder head, cylinder head and 4 cylinder base nuts. Drag the old cylinder upwards to release it from the piston.
2.Nettoyage and lower motor control:5 min.Clean the joint range from the motor housing with brake cleaner. Protect access to the bottom-motor with a clean cloth. Inspect the rod set and replace the piston axle needle cage.
3.Installation standard piston and cylinder:10 min.Follow the tip in Michel: Install a new original piston from the standard cylinder. Place a new base joint, slightly hose the NicaSil shirt with 2T competitive oil, and gently insert the cylinder over the segment.
Testing to the couple, control of the squish and purge:5 min.Tighten the cross-coded nuts to the couple recommended by TM Kart. Reassemble the cylinder head, make the squish control measurement over tin thread, put into water and carry a careful purge of the cooling circuit.
-FAQ SEO (Frequently Asked Questions)
Q: What does "Standard" mean for this TM KZ-R3 cylinder ?
A: The "standard" designation indicates that the cylinder is delivered factory raw with diagrams, ducts and Nicasil processing compliant with the TM Kart official series model. It has not undergone any preparation, editing or modifying a subsequent diagram, making it 100% in accordance with the approval regulations for official competitions.
Q: Does this KZ-R3 cylinder rise on the housings of a TM KZ-R2 engine ?
A: Although R2 and R3 engines share a near architecture, the R3 cylinder incorporates developments at the transfer and exhaust levels. To fully exploit the potential of the cylinder R3 and guarantee a perfect alignment with the housings, it is recommended to use it on the dedicated R3 bas-engine or check the alignment of the transfers when mounting on an R2.
Q: Is the cylinder delivered complete with the piston and seals ?
A: No, this article only includes the nicasil nicasil cylinder of TM KART origin. The piston, the needle cage, the base / cylinder head joint pouch and studs must be ordered separately (or recovered if they are new).
