Identifying Converter Components: 6 Key Features to Understand in Ford E4OD, 4R100 & 5R110W

无论您是在搜索核心桩或寻找特定部分以完成重建，整理福特E4OD的各种识别功能，4R100和5R110W转换器都可以驱动您疯狂。每个转换器的六螺柱版本恰好具有相同的K因子（叶轮叶片角度）几乎相同。如果您还没有教育叶轮伴侣的微妙轮廓差异，或者无法识别飞行员的关系到5R110W与E4OD和4R100相比安装垫差的，可以变得沮丧。以下是逐部分差异，以及用于识别每个的一些提示。

Covers

早期E4od盖（第一代）在螺柱底部有圆形安装垫（图1）。圆形垫转换器盖子容易裂开和围绕安装螺柱的底部泄漏。

为this reason, most round-pad E4OD converters have already been removed from service. The improved replacement covers feature a mounting pad that looks like a round pad with a flat machined on the inboard and outboard sides（图2）。

这种改进的垫在4R100和5R110W转换器上解决了E4OD上的裂缝/泄漏问题，并且仍然在4R100和5R110W转换器上使用。

从外面，后期E4od和4R100封面看起来相同。但是看着内部，你会看到E4od的侧面光滑，4R100摸索着握住离合器。因此，您可以使用4R100封面来构建E4OD转换器，但如果使用单个离合器，则只能使用E4OD盖子构建4R100转换器。5R110盖子也在内部造成覆盖，但由于较短的导频到安装垫关系，不能替代(Figure 3)。

涡轮机

用于E4OD，4R100和5R110W转换器的涡轮机看起来非常相似，并且在许多方面是相同的：它们是相同的直径并且具有相同数量的叶片。当您查看涡轮机伴侣到涡轮机枢纽的位置时，差异变得明显。E4OD涡轮机具有与C4，C5，C6和AOD涡轮机相同的试验孔径（2.765“）。它们还具有相同的铆钉圆，并使用相同的直径铆钉（.218”）。后期E4od涡轮机在铆钉表面具有轻微的轮廓浸渍（图4），早期涡轮机几乎是平坦的(Figure 5)但这似乎并不影响内部间隙。

The 4R100 turbines use the same rivet circle and rivet diameter as the E4OD turbines, but have a larger I.D. bore (2.955"). This is the piloting diameter for the turbine hub.

All of the 5R110W turbines have an I.D. that is about .015" smaller than the 4R100 turbine’s 2.940" I.D. The four- and six-stud versions of the 5R110W use the same rivet circle and rivet diameter as the 4R100 turbines. The eight-stud version of the 5R110W turbines move the rivet circle slightly outboard of the 4R100 rivet circle and use a rivet with about a .065" larger diameter. Ford may have been anticipating the larger rivet diameter when they made the I.D. bore .015" smaller.

In a side-by-side comparison, you will notice that the depth of the arch is slightly deeper on the 4R100 and 5R110W turbines than on the earlier turbines(Figures 6 and 7)。拱门是从油进入涡轮机的地方产生的，其中油离开涡轮机。

This means that the oil will travel a greater distance through the turbine and will spend more time in the turbine giving more push in the direction of the rotation. This may explain why Ford assigns a 105 K factor to the low-stall E4OD converter and a 110 K factor to the low-stall 5R110W converter, even though both use the same stator and have the same vane angle in the impellers. The 4R100 and 5R110W turbines have vanes that are .005" thicker than the earlier turbines, and all 5R110W turbines are furnace-brazed. Remember this when retrofitting an earlier turbine. You may want to limit their use to low-output applications.

Turbine Hubs

All E4OD, 4R100 and 5R110W turbine hubs are different and need to be matched to their respective clutch assemblies.

涡轮涡轮铆钉中心

所有的铆钉,除了eight-stud 5R110W, are 2.18” in diameter and vary in length depending on turbine hub flange thickness and whether the application uses a retaining ring.

定子

E4OD，4R100和5R110W定子是这些转换器最普遍的部分。所有这些都具有相同的设计和功能。如果定子盖和轴承组件正确地配合到涡轮机和叶轮，则它们将工作。

叶轮

The E4OD, 4R100 and 5R110W impellers come in three vane angles. The high-stall impeller has a vane angle that looks like a left-handed salute. It has a 140 K factor and is primarily used on small block gas applications. There is no high-stall impeller used with the 5R110W converters.

The low-stall impellers have a vane angle that is almost straight up and down. In most other converters, this would be called a medium stall. The E4OD converters with the low-stall impellers have a 105 K factor. The 4R100 and the 5R110W converters with the low-stall impellers have a 110 K factor.

The extra-low-stall impeller has a vane angle that looks like a right-handed salute. The converters with the extra-low-stall impellers have a 95 K factor. Most 5R110W converters use an extra-low-stall impeller. Most customer complaints are the results of using an extra-low-stall impeller for a low-stall application. This results in an off idle hesitation in a gas model or a turbo lag in a diesel model.

There are many generations of bearings and wear plates used between the stator and impeller and most are specific to a given impeller hub. Start by making certain that the stator cap and bearing are still available (some have been discontinued). Then match the impeller with the desired K factor to your bearing and stator assembly. Remember that you can always replace the impeller hub to come up with the proper mating part.

所有E4OD，4R100和5R110W转换器具有相同的直径导频，弯曲板的螺​​栓圆，总高度，31个输入花键（与C6）和定子花键相同。离合器组件将确定您使用的封面和涡轮机枢纽。所需的K因子将确定使用的叶轮。零件中的大多数不匹配将显示出太多或太少的内部间隙，或者整体高度太高或太短。
