所以还是根据螺丝大小 选工具大小最保险
大螺丝24寸 中螺丝12寸 小螺丝6寸 拧紧就八九不离十了
不用吃奶的劲不会拧断

属实。最好用midrange,不然情愿数值落在高端,所以我会选 1/4 inch torque wrenches (1.7-17 Ibs.ft)。话又说回来,15ftibs,如果不是非常关键的地方比如sensors,有必要torque wrench吗? handtighten+1/8 or 1/4 turn够了
不用解释,不是我的车,即使我也知道可以重新攻丝换一个稍大点的螺丝上去,我也懒得去管中国共产党未命空间党小组 写了: 2023年 9月 24日 17:08 现在汽车的油底壳都是铝的
如果钢制oil drain nut拧太紧会把铝螺纹破坏的。
不过即使螺纹破坏了, 也不用去换整个油底壳。
拿个大一号的tap 重新rethread一下, 换个大一号的 nut就行了
这种情况可以另攻丝换成大一号的螺丝简单一点.mondy 写了: 2023年 9月 23日 23:50 今天去年检,碰到一位开BMW 5系的哥们儿,自己换油把放油螺丝给拧花了,现在不停的滴机油,还落到排气管上冒烟。他自己买了个油底壳想换上但发现要拆元宝梁,车铺的师傅说换油底壳要十来个小时工时,光这个要1000多刀....
另外皮带张紧轮也有问题,皮带会打滑,还有什么节气门也有问题...
心里想,宝马的坑也太多了点.
Once the bolt snaps, the tension is gone. The remaining stem of the bolt should be easy to remove assuming you did not use thread locker. If it is sticking out a bit, try lockng pliers. If the snapped surface is not flat, try use a pick tool to turn it. You can also use a dremel with diamond grinding head to drill a small hole off center of the bolt. Then use a pick tool to get it out.bbs 写了: 2023年 9月 24日 13:27 打算星期一问问 junk yard。不过这玩意比较靠下,要先拆掉serpentine belt,power steering pump, 一个小支架,还得拆/挪一束电线,然后才能拆这个bracket,不知价格最后怎么样。ebay 和 有些 online supplier 是$40左右。

仔细搜了车库里柜子,居然发现一个类似的螺栓,比原来的短了大概5mm,如下图。能用吗?卸/装那个大的pulley的螺栓(19mm socket)时力好像挺大的,担心这个短的有点不够结实。seymour 写了: 2023年 9月 24日 22:19 Once the bolt snaps, the tension is gone.
