Presentation: TMKART certified seal

The crankcase seal for engines TMKART R1, R2 and R3 is designed to ensure absolute seal at the clutch housing and transmission. Manufactured according to the rigorous standards of the TM Racing factory, it makes it possible to confine the box oil and protect the internal components against external impurities.

• New generation compatibility: Specifically cut to adapt to the housings of the models R1, R2 and R3, ensuring perfect match with screw passages and oil ducts.

• High performance material: Composed of compressed high temperature resistant fibers and chemical aggressions of competition box oils.

• Reliability in the race: Avoid oil seizure that could pollute the track or cause a drop in the level of lubricant, critical for the survival of the gearmages.

- Installation and maintenance tips

1. Preparation: Clean the seal planes of the housing and the engine block. Any trace of old joint or fat will prevent a perfect seal.

2. Installation: Install the dry seal. The use of joint paste is not usually necessary if the seal planes are clean and not marked.

3. Tightening: Replace the housing and tighten the screws in a progressive way by following a "cross" scheme. This crush the joint uniformly without tearing it.

4. Verification: After the first roll, visually check the absence of leakage at the seal plane.

💡 Michel's trick

"On TM R1 or R2, we often open the crankcase to check the clutch. The trick: A crankcase should never be reused after disassembly! Even if he looks clean, he has already taken his shape and has compressed. My Pro Council: Always keep two or three goals in your case. If you need to intervene on the clutch between two sleeves, you will be happy to have a new seal to closely close and start stress without stress. "

❓ FAQ SEO (Frequently Asked Questions)

Q: Is this seal compatible with the old TM K9 or KZ10 models?

A: No, the motorizations R1, R2 and R3 have a different crankcase architecture. It is imperative to use the specific reference to the R range.

Q: Should the seal oil be oil before laying?

A: No, this type of seal is secured. Oil the seal could slide it during tightening and compromising the tightness.

Q: How to know if you have to change the seal?

A: As soon as you open the housing or if you notice a "oozing" fat at the bottom of the engine, the replacement is mandatory.
