今天早晨来找我,说车抖得厉害,check engine light闪。接上电脑一看,P0304。于
是把cyl4的coil和plug拿出来看看,plug正常,coil没看出有问题,于是把这个coil和
cyl1的coil对调,再发动,怠速1分钟即现怠速不稳和抖动,OBD2监控显示cyl1
misfire,于是连忙去dealer买了个coil装上。这个coil真他妈贵,算税$125,好在安
装非常简单。装上之后清除故障码,试车,一切正常。不难发现,此车以前换过一个
coil,这已经是这个车换的第2个coil了。遂想,一个107k miles的camry居然已经换了
2个coil了,而且一个coil要125刀,疯田的质量阿。。。
然后给做了个transmission的drain+refill+filter change,旧fluid那个脏啊。。。

"Try to avoid the gears that make the chain cross over at an extreme angle.
These "criss-cross" gears are bad for the chain and sprockets. Especially
bad is to combine the inside (small) front sprocket with the outside (small)
rear sprocket. This noisy, inefficient gear causes the chain to wear out
prematurely." |

toyota新的2az-fe发动机timing chain tensioner装在发动机外面,不是里面,
你这个问题是chain tensioner assembly No 1坏了,造成上timing chain skip
死机,下timing chain是没有问题的。
解决问题很简单,拆开上timing cover,拧松前后2个camshaft sprocket,重新
校对timing chain上的mark,对齐后拧死camshaft sprocket,然后装上新的No1
chain tensioner.就行了。
你找的人啥都不懂,不行去dealer吧,就告诉它们No 1 chain tensioner坏了,
dealer估计一听就知道啥回事情了 |

人生又完整了----换Timing belt历险 --序言.

上周末把timing belt换了。 由于中间犯了一个致命的错误 - 换完后第二天返工又来了
一遍, 几乎累虚脱了。roommate很忙,周六我一个人干的。从中午12:30一直干到晚上十点

1. 换TB调Tension,调Valve Clearence,都要等Engine冷了好久,
在常温下进行。parked overnight?
2. 不用remove P/S pump和Alternator,只要松了劲,
能取下drive belts就行。当然如果取了P/S pump扳转到一边,
可能腾出多一点工作空间,但不取也能工作。
3. 卸下旧的timing belts之前,一定要把各pulley/sprocket都转到位
(第一缸燃烧冲程TDC),卸下belts之后就不能随便转动各个轴了,
更不能使蛮劲转某个转不动的轴,那样很容易把汽缸里的阀门等顶变形。
4. 实际操作,为了确保DIY能够顺利进行,是先想办法松了Crankshaft
pulley bolt奠定了信心和基础后,再开始各项正常步骤。

d***y 发帖数: 1 | 11 Timing Belts
Your timing belt cannot be seen because it is encased behind the front engin
e cover. The timing belt is the connection between the engine’s crankshaft
and camshaft. As it rotates around the crankshaft and camshaft sprockets, pr
oper timing is maintained. On some engines, the timing belt may also drive t
he water and oil pump, or a balance shaft. Some engines may have timing gear
s or a timing chain rather than timing belts.
Just like an alternator or air conditioning drive belt, th |

d*b 发帖数: 21830 | 12 垃圾phd不知道,你要坚持用belt的话,variable timing就需要一套完全独立的液压油
路--因为belt不能沾油,而且variable timing一般都在cam sprocket上实现的,带
variable timing的belt系统成本比chain高多了,典型的可以看看honda accord的设计
,每个value都需要独立的液压系统。
自己都不懂的玩意,还是少发表意见来的好。 |

刚刚倒腾了一天,终于搞定。记录下简单过程,下次弄的时候可以看看。
小车已经跑了11万迈,要换正时皮带(timing belt),顺便也就把水泵和张紧轮一起换
了。
1。首先就是支车,卸轮子。
2。搞定后,把引擎支起来,然后卸掉右侧的发动机支架。
3。接下来除掉塑料覆盖件后,就可以看到曲轴pulley了。用冲击扳手卸掉那个大大的
螺栓,拿掉pulley。就可以看到里面的曲轴了。
4。然后把上面的支架配合件也拆掉就可以看到凸轮轴sprocket了。 |
