camshaft sprocket

If chain is not satisfactory, remove camshaft sprocket attaching bolt and remove timing chain with crankshaft and camshaft sprockets.

若正时链不令人满意，则拆下凸轮轴链轮固定螺栓，并拆下曲轴和凸轮轴链轮的正时链。

If one of the camshafts cannot be locked, loosen all the fastening screws on the affected camshaft sprocket by about one turn.

如果有一根凸轮轴无法锁定，则松开相应凸轮轴链轮上的所有紧固螺钉（旋转一圈左右）。

Remove camshaft sprocket and chain tensioner.

拆下凸轮轴链轮和链条张紧器。

Comparative study show that the drive system using the nonstandard sprocket is improved in many ways such as chain tension, contact force and friction force between chain and transmission components, tension force provided by tensioner, angular velocity of camshaft sprocket.

通过对比研究，采用非标准链轮的传动系统，其链条的张力、链条与传动部件之间的接触力和摩擦力以及张紧器的张紧力都有明显的改善。
