Crankshaft Bearing and Seal Set for Kymco and SYM Engines
This crank bearing and seal set is made for horizontal 50cc 2-stroke engines by Kymco and SYM, and it suits both air-cooled and liquid-cooled versions. The set contains NTN bearings together with matching crank seals, so it covers a full crankshaft rebuild. Keeping an engine running well depends on good parts, and this set is a dependable replacement for worn items. It is one of the Kymco scooter parts you can use to help your engine run smoothly.
What's in the Box
You get two NTN brand crankshaft bearings and two crank seals, which is everything needed for a complete engine rebuild. These parts are made in Taiwan, which supports consistent fit and dependable operation. Every bearing and seal is sized to sit correctly in the engine, helping it perform reliably.
Signs It's Time to Swap
Routine upkeep extends engine life, particularly in demanding use such as racing or off-road riding. Strange engine noise, a drop in power, or oil leaking from the engine are signs the crank bearings and seals may need replacing. Installing this set can bring the engine back to good working order.
