Yanmar Engine 3TNA72 Overhaul Rebuild Kit Repair Parts Product
Principle
Pistons and Piston Rings: The piston is one of the key components
of the engine and is responsible for converting the gases in the
combustion chamber into mechanical energy through reciprocating
motion. Piston rings are used to seal the combustion chamber,
prevent gas leakage, and help maintain normal operation of the
compression and exhaust stages.
Connecting rods and connecting rod bearings: The connecting rod
connects the piston to the crankshaft and converts the linear
motion of the piston into rotational motion through the rotation of
the crankshaft. Connecting rod bearings are responsible for
reducing friction between the piston and connecting rod while
providing stable support and lubrication.
Seals: The seals in this kit are mainly used to ensure the sealing
between various parts of the engine to prevent liquid and gas
leakage and ensure normal engine operation.
Valve and rocker arm: The valve controls the entry and exit of
gases in the combustion chamber, and the rocker arm assists in
opening and closing the valve. These components play a key role in
the combustion process, ensuring gas flow and emissions.
By replacing these parts, restoration and rebuild kits can repair
wear or failure in your engine and restore it to normal operation.
The principle of this kit is to improve the performance and
reliability of the engine by replacing key components, extend its
service life, and ensure that the engine operates within the normal
operating range.
