The SPI seal 26x37x7 mm is a critical component for the proper operation of the 2-time cycle of TMKART engines. Generally placed at the crankshaft, its role is to ensure a perfect seal between the interior of the housing (under pressure / depression) and the outside.
Prevention of air intakes: Prevents outside air from entering the bottom-motor, which would distort the carburation and might cause tightening.
Confinement of lubrication: Retains the air / oil mixture inside the engine to ensure the lubrication of crankshaft bearings.
Fluoré Material (Viton / FKM): Designed to withstand high temperatures generated by the crankshaft rotation and chemical aggressions of competition fuels.
| Feature | Details |
| Inner diameter | 26 mm |
| Outdoor diameter | 37 mm |
| Thickness (width) | 7 mm |
| Motor compatibility | TM KZ10, KZ10B, KZ10C, R1, R2, R3 |
| Standard position | Clutch or ignition side (depending on model) |
| Type | Double lip (usually) with holding spring |
MANAGEMENT SENS: The hollow portion with the spring must always be directed inwardly (side where the pressure is exerted).
Lip protection: When switching on the cranks or the crankshaft thread, use a protective sleeve or smooth tape for not cutting the rubber lip.
Lubrication: Apply a light layer of grease or engine oil to the inner lip before mounting to avoid immediate heating at first start ("dry start").
Installation tool: Use a sleeve or diameter tube identical to the outer diameter of the seal (37 mm) to piss it straight in its housing.
"A tired SPI seal is a motor that becomes impossible to adjust. The trick: If you see oil behind your ignition rotor or if your engine is slowing down, it is often this seal that is involved. My Pro Council: Do not look for the economy on this room. Systematically replace your SPI 26x37x7 joints during each change in crankshaft bearings. A nine seal to a few euros protects a motor that is worth thousands! "
Q: Does this seal fit for the ignition side or the clutch side?
A: On TM KZ engines, the dimensions may vary along the sides. Always check the exploded view of your model (KZ10C or R1 for example) to confirm that the 26x37x7 is the one you need for the specific side.
Q: Can we use a standard industrial spi seal?
A: Although the dimensions are the same, the joints for competition karting are often made of vituen to withstand rotation speeds and temperatures well above the industrial standards.
Q: How to know if the spi seal is dead without disassembling?
A: A common method consists of spraying a little brake cleaner near the rotating motor seal: if the engine speed changes brutally, there is a leak (air intake).
