Today, we are going to diagnose a terrible sound on a Mini Cooper.

今天，我們將診斷 Mini Cooper 上的一個可怕聲音。

Hey, you know, those Mini Coopers are terrible cars, they make all kinds of racket.

嘿，你知道嗎，那些迷你庫珀是很糟糕的車，它們會發出各種噪音。

Oh, that's the timing chain, that's no good.

Oh my gosh, have you checked your oil lately?

哦，對了，那個聲音，就是那個響聲。

First thing you must do is remove this inner fender liner out of the way.

首先必須把擋泥板內襯拆下來。

This is done by simply removing this lower splash shield.

It's held in with some Phillips screws, and then you got our lovely friends.

它是用一些十字螺絲固定的，然後就有了我們可愛的朋友們。

The old push pins for which you just kind of need a pick and a tool and a screwdriver.

老式的大頭針只需要一把鎬、一個工具和一把螺絲刀。

And here's the culprit, there is chunks missing from the drive belt.

罪魁禍首就在這裡，傳動皮帶上有大塊缺失。

To inspect the drive belt, simply install a 19mm socket onto the end of the crank pulley and turn clockwise with a breaker bar.

要檢查傳動皮帶，只需將 19 毫米套筒安裝到曲柄皮帶輪的末端，然後用斷線鉗順時針旋轉即可。

Why is this a problem and why does it make noise?

為什麼會有這樣的問題，為什麼會發出聲音？

Well, it makes noise because the friction wheel runs up here and drives the water pump right up there.

之所以會發出聲音，是因為摩擦輪在這裡運轉，帶動水泵在這裡運轉。

And because the belt has a gap in it, when it comes around to this position, it collapses, pushes like up against this drive gear or the friction wheel, and that noise gets transferred to this unit.

由於皮帶上有縫隙，當它轉到這個位置時，就會塌陷，推到驅動齒輪或摩擦輪上，噪音就會傳到這個裝置上。

Now, you can check this because there is a pull tab here, you pull this tab out, releases the friction wheel, there's a small hook to hold the friction wheel in place so it does not reset.

現在，你可以檢查一下，因為這裡有一個拉片，你把這個拉片拉出來，摩擦輪就會鬆開，還有一個小鉤子把摩擦輪固定住，這樣它就不會復位了。

You can now manually spin the friction wheel and carefully inspect it for damage.

現在可以手動旋轉摩擦輪，仔細檢查是否有損壞。

Let's see it with the friction wheel disengaged, the tab pulled and held in the lock position.

讓我們看看摩擦輪脫開後的情況，拉動拉片並將其保持在鎖定位置。

We're going to re-engage the friction wheel and see how much worse this sounds.

我們要重新齧合摩擦輪，看看情況會不會更糟。

好吧，讓我們看看這聽起來如何。

Now here's the thing, I know that that friction wheel is not bad because when I have it released and I spin it, it feels fine, there's no chunks, I've inspected the water pump drive, it's a nice solid piece of rubber with no chunks of rubber missing.

現在的問題是，我知道摩擦輪沒有壞，因為當我鬆開摩擦輪並旋轉它時，感覺很好，沒有任何碎塊，我檢查了水泵驅動裝置，它是一塊堅固的橡膠，沒有任何碎塊。

The problem on this car is simply the drive belt.

We're sorry, the number you have dialed is not in service at this time.

很抱歉，您撥打的號碼暫時無法接通。
