趁著聖誕節長周末和幾乎連在一起新年,把拖了不能再拖的最大的工程換離合器給做了。離合器有問題的現象就是是不能加太大的油,否則,離合器就空轉打滑。

先聲明,以前我並不是自己修車, 都是送車行修理。但經過幾次被修車的經曆,遂決定自己幹。

我的Corolla 讓車行換機油。車行忘記把油蓋裝上。我開了幾英裏後,發現車前蓋有煙霧冒出, 停車靠邊後,打開車蓋,油煙噴薄而出, 整個車全部浸在機油裏。車被拖回車行。跟車行交涉了多時,車行隻給做“steam cleaning”和更換曝露在外的皮帶。拿回車前檢查,各處確實都洗幹淨了。但沒過多久, 全車又都滲出機油。整個車沉浸在一層厚厚的油泥當中。永遠無法清理幹淨。

於是決定自己換機油,但我發現我的Corolla 上的oil filter根本無法卸下來,我不知那是用了多大的力矩上上去的。隻好用長鉗把它夾扁,才卸下來。

另一新輛車Camry, 買車時買了service pack, 一直由dealer維護。service pack期滿後自己rotate tires.發現按spec的力矩卸輪胎,根本卸不下來。隻好用brake bar和一米多長的 cheater bar,才把輪胎卸下來。

想想看, 我們的車,多數的情形不是開壞的, 是被修壞的。

當然,自己修車,每修一次,你就會有一次成就感。你也會對你的車加深一次了解。哪裏有一點不對,也會更好的判斷。

就像 說的,每次打開 HOOD,一種親切感就油然而生,好象看著自己的內髒。一切那麽熟悉,這個是不是該換了,那個是不是該修了。

我們都是懷舊念舊的人,也是一個懂得感恩的人, 看到有的很新的車拋錨在路邊,而我的看著舊舊的車一轟而過,那種感覺是滿足和自豪。

 

扯遠了。回歸主題。

想先把心得,走的彎路,說一下。

1)    做這樣的project, 一定要有此車的service manual。基本的修車步驟,各處的力矩就心中有底了。

2)    事先要多看相關的youtube. 看人家是怎麽幹的。哪怕跟你的車不一樣,也看看無妨。你的動手能力,隨著你觀摩別人的修車技巧和手法會有長進的。你甚至還能看出別人那裏做錯了。你如何不犯同樣的錯誤。

3)    事先用ATF fluid 浸潤exhaust上所有螺栓和螺母一晚,卸下就易如反掌。比WD40好用多了。卸下的螺栓和螺母還可以再用。我唯一錯過了一個藏在manifold後邊的螺母,頭天晚上沒看到。在卸下前才看到,馬上用ATF fluid 浸潤兩三個小時,但卸下時還是把螺母卸禿了。

4)    新近從Harbor Freight買的兩個工具給此次修車很大的幫助。

a) 1/2 in. Heavy Duty Electric Impact Wrench, 力大,卸manifoldexhaust, wheel nut , Ball stud bolt and nut, drive shaft nut 幫助極大。http://www.harborfreight.com/12-in-heavy-duty-electric-impact-wrench-68099.html

b) 3/8 in. Drive Speed Socket Wrench,扭力150LB 後邊的那個T-handle 太給力了。

在狹小的空間那真的是無價之寶呀。http://www.harborfreight.com/3-8-eighth-inch-drive-speed-socket-wrench-4434.html

另外一個3/8 in. Drive socket wrench 卸下螺絲時一用力, 就壞了。
 

 

5 因為這個工程複雜, 耗時長, 在拆下部件時一定要記得照相,每一個部分都照,   “before and after”。久了,還真的 記不清是如何卸下的了。我就吃了這個虧。有兩顆螺絲說什麽 也想不起是從那裏卸下的了。冥思苦想多日,反複查找, 才裝回去的。當然,在拆的時候,手是髒的,照相頗不方便。心裏也是急的,想著拆了一個就接著拆下一個。千萬不要想省事,裝回去想不起來怎樣卸下來的才耽誤時間呢。就是裝回去了,心裏也嘀咕是不是裝對了。那才折磨人呢。
6) 卸下的部件最好一部分一部分的分開放好, 螺絲螺杆能擰回原處的盡量擰回原處。不能擰回原處的,用小袋子裝好,寫上字注明出處。
7)無論拆卸還是裝回,一定不要心急,
對了比做快更重要。做錯了,反而耽誤時間。拆卸時可用電動工具,回裝時要用手動工具,用對的力矩緊固。
8)一定要用common sense,不要想當然。比如engine mounting LH NO.1 bracket 的螺母力矩在service manual 哪裏都找不到。但看到 Engine rear mounting bracket
bolts的力矩列出是36.5 lb-ft。就照著這個力矩去上,結果就把這個螺杆上斷了。其實我的
common sense告訴我,不應該上這麽大的力,鬼使神差,就這樣想當然去上,馬上出錯了。就是把下麵的這個圖和照片裏的一個螺杆上斷了。網上去買這個engine mount 都買不到。好在這個engine mount的螺杆是鉚釘式的,把舊的鋸掉,在原地鑽了個洞,換了一個螺杆上去,解決了問題。

          8) 一開始就把車架的要夠高,最好用四個jack stand 把車架平。這樣在車下動起來有足夠的空間, 回灌transmission fluid 時也不用擔心車身不平,灌不滿。transmission 卸下下來,也很容易的移出來。其實,直到整個工程做完前,車都不用下架。
           9) 細心很重要。兩個彎路,每次都耽誤了一天。認真的總結,都是不細心的結果。
a)      第一天已經基本拆到transmission了。第二天信心滿滿,認為隻要兩三個小時就可以把transmission卸下來。誰知 最上邊的那顆螺栓很長,出來正好和冷卻液的硬鐵管碰在一起。無論如何那螺栓是拿下不來的。心裏一直罵日本人,設計個冷卻液硬鐵管也不把彎弄大些,難道你每次卸下transmission都要把冷卻液硬鐵管先卸下不成?那硬鐵管可是裝在發動機的後麵, intake manifold 的底下。intake manifold 都要拿下來那可是另一個大工程了。人 心急的時候,智力就低,觀察就不仔細。直覺就占了上風。覺得必是要把硬鐵管上翹起,那顆螺栓也就下來了。也主觀的認為,那硬鐵管另端一定是用橡膠密封圈密 封的,可以轉動硬鐵管,不會泄露。可是那鐵管硬是轉不動。還好沒有蠻幹,用蠻力。就這樣,一天過去了,也沒卸下transmission。晚上休息的時候,是腦子最清醒的理智狀態。理智告訴我那顆螺栓一定有機巧。第二天爬起來仔細一看,果然,那顆螺栓靠近發動機的螺孔套著那該死的guide pin. 以前看YouTube人人都說guide pin.  到現在我也隻卸下一個guide pin 咋就忘了查找guide pinguide pin一移動,螺栓就下來了。Transmission不扶著,就要倒下了。歡快的倒下了。
b)
往飛輪上回裝input shaft bearing, 有照片對應看,總覺的input shaft bearing有幾毫米沒有完全入位。用socket 和榔頭砸了又砸。就是不往裏去了。所以覺得應該這樣吧。回裝Transmission時,Transmission和發動機就是不能合縫。用上螺栓緊固都沒有辦法合縫。來回搖動Transmission多時,都不見效果。幾乎一天就這樣又快過去了。所以決定收工, 好好思考。結論是input shaft bearing也許有公差, 與飛輪的凹槽後部的公差正好不匹配。要卸下input shaft bearing 手工打磨後重上。往回裝input shaft bearing的時候,忽然看見那排列整齊的六顆螺母內角尖有一點點擊打的痕跡。那是我用的socket稍稍大一點,留下的。換了一個小一點的,隻稍稍敲打,input shaft bearing完全進入。這個教訓太深刻了。再次的仔細讓我有了一得。那個讓我卸不下Transmission guide pin 在卸下的過程中的種種折騰,有些變形。用肉眼是很難發現的。但用手往發動機那邊或者Transmission這邊推入,都不能完全進入。Transmission和發動機不能合縫是有兩個culprits, 不是一個.  auto zone, Napa 買這個guide pin 對不起,沒賣的。我們就是DIY 套上螺杆輕輕敲,手工磨。終於guide pin兩邊都能進入,沒有間隙。這次再上Transmission嚴絲合縫, 一次成功。祝賀自己一下。

看圖說話:
拆卸前, driver side drive shaft


飛輪後麵的護罩。兩顆螺絲固定。 必須先卸下這個護罩, transmission 才能以發動機分離。


剛剛卸下的
transmission。充滿汙垢。


徹底清理tranmission 的汙垢。


清理幹淨, 換好 clutch release bearing, 抹上grease後的transmission.


上grease 的近照,不能多,要剛剛好。clutch release bearing 千萬不能沾到grease.


尚未卸下的舊的pressure plate.


近看pressure plate的磨損變形情況



新舊clutch disk 對比
 

新換的input shaft bearing, 看到那六個螺絲頂內角的砸痕了麽?仔細看。
打磨過的飛輪, 事實證明,這樣狀態的飛輪,一點問題都沒有。


這是新裝好的離合器。記得一定要幹淨,不得有任何的油汙。用很多的brake cleaner 清洗。
