检查 防翻滚保护架 (ROPS) 的两侧螺栓有无松动、破损或损坏。 如果发现有任何损坏的防翻滚保护架螺栓 (A) 或 (B) ,则更换所有的防翻滚保护架 螺栓 (A ) 或 (B) 。
只能用原配件更换任何损坏的螺栓和丢失的螺栓。
拧紧任何没有破裂或损坏的已松动的螺栓。
将防翻滚保护架螺栓拧紧至下列扭矩。
防翻滚保护架螺栓 (A) - 拧紧11 个上螺栓到1300 ± 150 N·m (950 ± 110 lb ft)。
防翻滚保护架螺栓 (B) - 拧紧 14 个下螺栓到1800 ± 200 N·m (1325 ± 150 lb ft)。
注: 安装 ROPS 螺栓前,在 ROPS 螺栓螺纹上涂抹机油。如果不在螺纹上涂抹机油,螺栓的拧紧扭矩可能不正确。
注: 如果发现有破损的螺栓,请告知卡特彼勒代理商。
