• A silent chain (link grounding type) type has been adopted for the timing chain to reduce tapping noise caused by sprocket engagement.
• Engine oil inside the engine front cover lubricates the timing chain and each sprocket. The pin part of the timing chain is nitride processed to improve abrasion resistance.
Timing Chain Specification
• An oil pressure type chain tensioner has been adopted for the timing chain tensioner. The tension of the timing chain is constantly maintained using oil pressure and spring force in the chain tensioner.
• The oil pressure type chain tensioner consists of the following parts: Piston spring that depresses the tensioner arm, and a check ball that maintains pressure to the tensioner arm.
