Old man on the stand-Ten years of Langdong replacing clutch

It’s May 2022. Time goes by too fast, too fast
Sigh the speed of time, also sigh the impact of the epidemic, Langfang this city, March-April home isolation for 40 days, nucleic acid testing done more than 30 times, I hope the epidemic will leave the land of China as soon as possible!
In fact, we have been planning to change cars since last year, either there is no car, or the preferential subsidy is reduced, it seems that there is no fate with the new car, to put it bluntly, it is still “poor”, right? Long move accompanied me to the tenth year, nearly ten years, accompanied me through 110000 kilometers, strictly speaking, the mileage is not high. Manual movement is good anywhere, the only deficiency is to manually block the car, after a long time, the clutch pedal is very heavy, traffic jam for a while, foot pain. The reaction of the riders in the car club was the same. They originally wanted to stick to it and wait until they changed trains. But there are too many uncertainties caused by the epidemic, so make sure you have sense of security with rice in your pocket. After all, there is also a golf machine, which is only 23000 kilometers away. That is, the space of the second-child family car is stretched, so work hard!
No post for a long time, like the son is old, but also difficult to coruscate luster, slowly become an old car, become the memories of many people’s hearts. But if you think about it, how rare it is to have a car to accompany me for 10 years, so let this old car accompany me to go further. The old horse in the stable still wants to run a thousand miles.
Tell me about the maintenance experience of the car. Fault phenomenon: in fact, it can not be regarded as a fault, first of all, manual clutch problems will have a very obvious performance, clutch skidding, start, shift jitter, etc., I have to move without the above phenomenon, just a simple clutch sinking, but according to the judgment of the old driver, the clutch three-piece set must have aging-clutch plate, pressure plate, separation bearing, look at the picture!

The old horse in the stable loves my movement.

It takes half a day to replace the clutch three-piece set, mainly because there are too many things to disassemble.
1. Above: remove the battery and empty filter box
2. Below: remove tire, guard plate, lower arm, half shaft
Because replacing the clutch requires disassembly and adjustment of the gearbox, which is a big project.

After dismantling, the gearbox oil needs to be removed. The gearbox oil changed at 80, 000 kilometers is very clear. At present, more than 110000, 30, 000 kilometers of transmission oil is very clear.

Prepare to disassemble the half shaft after oil discharge.

The old master is very serious. after the half-shaft is dismantled and adjusted, we need to build a gearbox. The gearbox is pure aluminum, or it is relatively lightweight.

The gearbox landed on the ground, and there was almost no clutch debris in it.

Separation bearing, separation bearing has certain wear
Shift principle: fork shift separation bearing-press clutch pressure plate

Pressure plate

Original clutch brand: SECO, check that it is made in Korea

The clutch plate has been taken off, and the wear is still very uniform.

The thickness of the clutch plate is still very thick. I don’t understand why the clutch plate is so thick and the clutch is still so heavy.

Flywheel, touch it with your hand, it’s smooth.
Because usually driving is very regular, but also never ejected, and then searched, many of the clutch dry scrapped, are excessive violent driving, note, is excessive, in fact, the clutch is not so fragile

The replacement clutch brand, PHC, is also a modern special brand. PHC belongs to Valeo.

New clutch piece

New pressure plate

I had better search for many reasons for the sinking of the clutch, and after comparing the two pressure plates, I came to a conclusion: the problem lies in the “spring claws” of the pressure plate (I don’t know what its scientific name is). This uneven grinding, coupled with the wear of the separation bearing, caused the clutch to sink.

Loading of new clutch plate and pressure plate

Get in the gearbox.

An old car, perhaps slowly second-hand car value will be lower and lower, but once accompanied by the time, is the second-hand car value can not be reflected
Time is not old, we will not break up.
Thank you
