Auto repair practical tips - homemade tools articles

On the way to the car, the conditions are limited circumstances we will inevitably do some easy to do their own maintenance tools. Here we take a look at what we have done the tools, what we use it?

1, BMW 760 car door valve repair tool

PS: We do not have to remove the cylinder door oil seal, in the car easy to get. Xiao Bian had done before, but is a simple, as shown below, but there is no red circle part, that is, to do a stent, the use of carry the principle of pushing the valve spring. It is worth noting that this valve door seal, to sub-cylinder to. For example, four-cylinder engine for the 1, 4-cylinder valve oil seal, you must let the 1,4-cylinder piston at the top dead center, in order to disassemble the valve spring, or valve into the cylinder, waiting to lift the cylinder head.

2, double camshaft positioning tool

PS: a pair of double camshaft timing belt, bad change? The The DIY, easy to get.

3, the ignition signal detection tool

PS: Xiaobian that this is very good, very creative, this is the use of relay control coil enameled wire, in a paper tube around a lot of circle, and then fixed with tape protection, the two feet connected to the coil A light-emitting diode, make full use of the principle of mutual inductance in the electromagnetic principle.

The use of this method is to close the ignition switch, the key from the middle through, when we switch the key, the key chip induction coil sensor to the chip, resulting in point flow at the same time, will produce a mutual inductance in the coil coil, light-emitting diodes will flash.

4, disassemble oil filter tool

PS: the use of abandoned timing belt, do simple tools Oh.

5, self-made pry card tools, with the lever up

PS: make full use of the replacement of waste to make their own want to use the tool, this is the use of the rear box or the hood of the hydraulic rod made out.

6, do their own T pole, is easier to buy than buy

PS: the same is done with a hydraulic rod and a sleeve.

7, homemade test lights

PS: This is the use of two different models of different colors of light-emitting diodes and a 600Ω resistor to do, the two diodes in reverse connection, that is, either positive or negative will have a light.

Let's take a look at the little partner's work

Use a bottle to make a shade, protect the bulb, and think of a stick. One end made of a pointer, the other end made the clip is more useful.

9, homemade pumping unit

PS: manual type: with this brake oil, called a cool. My mother no longer worry about my demolition of the brake when the pump is full of oil.

After reading the manual, we come to an automatic.

PS: Xiaobian just want to say that this vacuum pump will not be a little high cost ah, then you determine how much oil can be installed, change the oil but also tossing back and forth several times. At the beginning, Xiaobian, but with a hand-push fire extinguisher to do a pumping unit, then we used the air conditioning pumping the pump, but unfortunately did not take pictures, a little regret.
