Chain tensioner
The major function of tensioner is optimizing the movement of chain drive system by using spring constant and oil
pressure in the tensioner.
The tensioner performs function of adjusting chain tension to be always tight, not loose, while engine running. By doing
so, can reduce wears of each guide rail and sprocket.
Tightening torque
65 ± 5.0 Nm
(Installed on the cylinder head)
Guide rail
Guide rail is used to optimize the movement of chain drive system like tensioner.
Guide rail can prevent chain slap when chain is extended and reduce chain wears.
Guide rail is needed especially when the distance between the sprockets are too long.
The material is plastic.
• Location of guide rail
- Tensioner guide rail: Between crankshaft sprocket and exhaust camshaft sprocket
- Upper guide rail: Between exhaust camshaft sprocket and intake camshaft sprocket
- Clamping guide rail: Between intake camshaft sprocket and HP pump sprocket
- Lower guide rail: Between HP pump sprocket and crankshaft sprocket
Chain
• Chain type: Double Bush
• Pitch: 9.525 mm
• Load limits: 19,000 N
• No. of links: 144 EA
• Overall length: 1371.6 mm
• Replace when the chain is extended by 0.5 % from overall length (Replace if extended by over 6.858 mm)
