LUBRICATION SYSTEM
.
• A silent chain (link connecting type) has been adopted to the oil pump chain to reduce chain operation noise
when the chain and the sprocket engage.
• The engine oil in the engine front cover lubricates the oil pump chain. The wear resistance has been improved
by the nitriding processing of the pin constructing the oil pump chain.
• The durability has been improved by heating the sintering material on the oil pump sprocket inside of a furnace.
