丰田U140e详细说明

车辆恢复是耗时的过程。一些项目仍然散落于车库,比计划或升值更长。细节的定义和努力随着车辆的类型而变化。越野的Bronco可能会获得最后一套贴花,老式收藏家获得油漆和抛光。

If you have ever power buffed a paint finish, you realize that if you stay in one place too long or use an aggressive polishing compound, eventually the finish will buff out and then off. That’s probably not a concern on the Bronco destined for the woods, but on the 67 Camaro, it’s not good. Detailing also refines the interior. I recall a used car account, which routinely dropped off vehicles for “quick jobs”. One had repetitive electrical issues, returning this time with an inoperative power window. After removing the trim panel, I found the door was compacted above the motor with dried mud. If this had been a Bronco, with roll cage and big tires, it could be explained with a good story behind it; but this was a luxury car. I would presume when they “replaced” the interior and cleaned out the soft mud, the doors had been overlooked. In appearance, both the interior and exterior of the car were detailed perfectly.




身体细节很像传播工作,一个彻底的工作需要时间和经验erience. Years ago we were cleaning cast drums and shafts to avoid flushing the material back into the governor. Today, debris is attracted to a solenoid or sensor by their magnetic field.

该材料也可以通过离心力保持,例如转换器阻尼器。

通常,磨料材料变得嵌入,但是当添加新鲜流体或发生温度或压力时,它受到干扰。然后将悬浮材料自由地在阀体和螺线管孔处抛光,就像通过涂料的功率缓冲器一样。

为了说明各种磨损过程,所示的铸件图4.是钻孔的一个很好的例子47RE州长换档插头。

在most instances, bore wear is hidden and you must inspect the casting at different angles along with additional lighting. The loaded side of the casting will wear first. Loading is generally from the force of the fluid pushing against the surface of the valve, causing the spools to rub hard against the casting. Valves that have stout springs, load both end spools in a pattern 180 degrees apart from each other.

目视检查需要完整的拆卸。在图5.,墨迹标记(例如,钻孔7的半路)表示对此目视检查的关键点U-140E.valve body. The ink marks at the end plug retainers (such as bore 12) indicate they must seal. These end plugs and all the circuits with the oval drawn around them in图5.and6.全部可以真空测试。




需要校准的真空测试站来执行真空测试,并在此处提供通过/失败示例标准。一旦设置了一个系统并校准,它具有可重复的结果并提供可靠的数据。真空测试导致特定价值而不是对磨损和泄漏的判断。当隔离两个线轴时,可接受的公差读数通常是19“或者在一个阀芯上的真空和17”加上。该测试不是细节或清洁的短切,并且可能需要泡沫垫或板隔离一些电路。U140E不容易真空测试,因为一些电路在铸造的两侧穿过。照片上的圆圈区域表示将不需要特殊板的有效U140E真空测试点。有关设置真空测试站的信息,请访问m.xiecongrong.com。




在没有线性或可变力移位适应的较旧单元中,我们可以通过打开离合器馈电孔来补偿电路损耗。通常,对具有控制离合器的TCM的单元没有影响,施用和进给压力。在一定程度上,螺线管输出可以通过TCM改变以补偿磨损,依赖于自适应策略或敲击细胞。一旦阀容差变得过度,调整超出了TCM或螺线管可以改变的。另一种替代方案是提升线压或离合器压力以缩短换档。这将导致TCM在任何一种情况下都会反应和退出。找到一个问题的根本原因是可以恢复葡萄酒的葡萄酒和感觉与细轿厢(吉普车,Bronco等)进行比较。这种成就或救援的感觉与你从车库中滚动的项目车辆滚动的那一刻,你的妻子得到了停车位。
