When it is necessary to pay attention to the buckle, the weight of the small excavator should not deviate from the faucet,Excavator Parts otherwise the cylinder head will be damaged. Pull out the jacket with three-quarter screws. Do not pull Too hard to prevent slippage of the jacket.
After successfully pulling out the outlet sleeve,Excavator Parts clean the internal iron and carbon deposits and the oil deposits in the oil cylinder. After cleaning, install a new mouth sleeve and install it. When installing, the mouth sleeve has different types of seals, so pay attention to the seal ring After installing the sealing ring,Excavator Parts use a special tool to install the sealing ring. Before installing the mouth sleeve,Excavator Parts the small excavator must apply butter on the sealing ring to ensure that the sealing ring is in place. No damage to the sealing ring.
