- 将 1 号气缸置于上止点位置（压缩冲程）。 请参阅测试和调整, "查找 1 号活塞上止点位置"。
注: 间隙过大可导致制动器性能下降，没有间隙可导致排气门在发动机升温时打开。
- 通过执行以下步骤设定 1、3 和 5 号气缸的制动器间隙。
(a) 松开螺钉 (2) （多圈）的同时固定间隙调整活塞 (3) 。
(b) 逆时针转动间隙调整活塞 (3) ，直到制动器调整螺钉 (4) 接触排气门桥销 (5) 的顶部。
(c) 顺时针回调间隙调整活塞 (3) 一整圈加 90 度。 请参阅图 94。
(d) 固定间隙调整活塞 (3) 。 将螺钉 (2) 上紧到 4.5 ± 0.5 N·m (40 ± 4 lb in) 的扭矩。
