气门挺杆导向座弹簧只可在气门挺杆上安装一次。 如果将气门挺杆导向座弹簧从气门挺杆上拆下,必须安装新的导向座弹簧。 如果从气门挺杆导向座上拆卸气门挺杆后没有从气门挺杆上拆下导向座弹簧,则无需更换气门挺杆导向座弹簧就可在原先位置安装气门挺杆。 |
注: 检查导向弹簧 (3) 和 (4) 是否磨损或损坏。
- 检查导向装置 (5) 的气门挺杆孔是否粗糙或磨损。 气门挺杆孔的直径为42.00 ± 0.02 mm (1.654 ± 0.001 in)。 单体喷油器挺杆孔的直径为56.00 ± 0.02 mm (2.205 ± 0.001 in)。
- 确保气门挺杆的导向装置中的润滑油道未被阻塞。
- 检查每个挺杆体是否粗糙或磨损。 气门挺杆 (6) 的直径为41.91 ± 0.010 mm (1.650 ± 0.0004 in)。 单体喷油器挺杆 (8) 的直径为55.90 ± 0.010 mm (2.201 ± 0.0004 in)。
- 检查滚柱 (7) 在气门挺杆 (6) 上是否磨损、损坏和松动。 检查滚柱 (9) 在单体喷油器挺杆 (8) 上是否磨损、损坏和松动。
- 确保单体喷油器挺杆 (8) 的润滑油道未被堵塞。
