Today, just in the forum to see this article called "change the guide valve" article, feel very valuable, it was arranged, I hope to help you, let us learn to change the whole process of walking pilot valve:
My small excavator has been working for quite a long time. It's the time of menopause. While working and watching the dripping of hydraulic fluid, it is heartbreaking, such as gouging out the heart and flesh, and it is all money. Business is hard to do, rice is less and the pot is burning... It's hard! Also cannot watch the flow, has to bite the tooth to borrow the rice pot, cuts out the wound, the pain does not consume for a long time, decides to change the new.
Call the manufacturer first and ask the price. When you ask, you almost fainted. Four thousand and eight hundred, frighten me! The beating of the heart is speeding up. I really think it is made of gold, which frightens my farmers to be illiterate and be slaughtered. Also asked about the Korean independence, to refit the more than 2000, it is not very convenient. Later asked a specially matched, that is, by-plant, directly installed without change, only 1,800 yuan, but also three packages for half a year, ah! The difference is so big that three thousand oceans are bad. Whole difference of half a day's net profit, the Deputy plant on the deputy plant, the original plant is also used for thousands of hours leakage, can save a few pieces is a few pieces, order immediately. Shun Feng express is also very powerful, three days on time to the goods, open the packaging check, look at the difference and the original is not very different.
Open the package walk pilot valve
Take the appearance of the floor glue
Take off the floor glue, you can't bear to see a lot of confusion. You can't see it everywhere. You can't blame two barrels of oil a month. Start with the top of the pedal rubber, you can see a few inside the six corners of the screw, take down the pedal can be taken down, so that it is more easy to take the screw.
Walking pilot valve warhead
Take the pedal away and see the bullet! Oil seepage is the place. The floor is opened and the bottom is all oil. There are only six pipes in the pilot assembly. It is not difficult to remember. One is in the oil, one is in the back, two are forward, two are backward, two are left and right. I'm afraid I can't remember it. There's a way to tie it up in the direction. It will never be wrong!
Walking pilot valve assembly
Remove the original joint
After taking down the assembly, the original joint is dismantled, and the best is to be coated with raw material or screw glue to prevent leakage. The screw does not force hard to prevent the screw from breaking because the joint is empty, the strength is not enough, and it is difficult to match. Don't waste time and money because of a screw.
Remove the handle handle
After fitting the connector, remove the control handle and install it in the original direction. It may be deformed for a long time. You can try it before loading. Do you have two balance? If deformation, remove the water pipe, then tighten it.
P is oil, T is oil back
Remember that these two tubing are not wrong. If you install the wrong way, you may damage the assembly. P is oil and t is oil. General oil inlet joints are marked, and careful inspection is not wrong.
The walking pilot valve was replaced
At last, you can finish cleaning with a towel. You can try the machine. Push up and down the front and back and let the machine hold back. Try to see if there is any leakage in the connector and whether the direction is deviated. Check out, everything is normal!
