拆卸前，用彩笔标记正时链条转动方向和正时链条。

Before removal , mark the timing chain rolling direction and timing chains with a coloured pen .

安装正时链条时，切勿逆发动机运转方向转动曲轴。

Never turn the crankshaft against the running direction of the engine when the timing chains are fitted .

执行目视检查以检查张紧轨和导轨上正时链条的位置。

Perform a visual inspection to check the position of the timing chains on the tensioning and guide rails .

只能在曲轴上（不得在凸轮轴上）转动发动机，否则正时链条可能会跳起来。

Only turn the engine on the crankshaft and never on the camshaft as the timing chain can jump over .

请始终在曲轴上转动发动机，而从不要在凸轮轴上转动发动机，因为正时链条可能会弹离正确位置。

Always turn the engine on the crankshaft and never on the camshaft as the timing chain may jump out of place .

为了在正时链条中获得足够的间隙，必要时可以前后转动已松动的凸轮轴调节器。

为了提高国产正时链条的性能，研究了05BT-1汽车发动机正时链的磨损失效机理以及销轴、套筒和滚子等元件摩擦表面的磨损形貌特征。

The paper studied the fault mechanism of the automotive engine timing chain as well as the worn surface morphology of the rubbing pair of bush and pin and roller based on the analysis of test .

结果表明：正时链条在工作中滚子的断裂及疲劳剥落、套筒内的疲劳点蚀和氧化磨损、销轴的氧化及微动磨损是正时链系统失效的主要原因；

The result shows that the major factors of the timing chain failure are the roller 's break and fatigue flake off on the roller surface , fatigue wear and tear and oxidation on the sleeve inner , and pin 's oxidation and fritting wear .
