Any motorist periodically faces the need to perform high-quality vehicle repairs. Many people prefer to trust this process to professionals, but experienced drivers perform all the manipulations on their own. But not every malfunction can be effectively corrected without the help of special devices. If it is necessary to carry out high-quality repairs of the gas distribution unit, then it is imperative to have a valve cracker on hand. Such a product will greatly facilitate the manipulation of the block head. The master will be able to depress the spring in order to freely remove all the crackers.
Description
First of all, the master needs to remember exactly how the valves are fixed in the gas distribution mechanism of any motor. Experts note that the intake and exhaust devices are held closed by a strong spring. It is fixed on the valve stem with a plate and crackers. To quickly remove the plug, you need to compress the spring. It is with this task that the dryer does an excellent job.valves. Such a unit is sold in any automotive store, but in order not to spend personal savings, you can try to make it yourself.
Varieties of models
Today there are two categories of valve crackers. Each product has its own performance characteristics, which are highly valued by professionals:
- Lever assembly. This is a universal fixture. It can be used both in relation to the removed head, and without its preliminary dismantling. The only drawback of the device can only be called that the work must be done in pairs (one person depresses the spring, and the second takes out crackers). Home craftsmen prefer to make such a valve cracker with their own hands.
- Screw model. This product is more convenient to use, as the master can perform all the manipulations on his own. It should be noted that the product of this category is relevant only if the unit head was previously dismantled.
How to use
First of all, you need to carefully put the extreme bracket of the cracker on the hairpin. Only in this case it will be possible to hold the bed in order to screw the nut onto it. The figured washer is installed on a plate, which not only covers the springs, but also presses the lever. The outer side of two crackers is presented in the form of a small cone. In some cases, with a slight pressure on the plate, it can be fixed on the rodvalve. In such a situation, it is necessary to hit a little from above in the middle of the lever with an ordinary hammer. Only when the springs are compressed can the crackers be removed from the socket.
Production principle
You can build a high-quality valve cracker with your own hands in just a few hours, using simple drawings during work. The unit is based on a lever with two powerful brackets attached to it. For fixing, you can use ordinary nuts and screws. As a result, the master should get a hinged joint. To assemble the fixture, you need to prepare:
- Classic welding machine.
- Bulgarian.
- Two small strips for making brackets.
- Standard blank of durable metal for the lever.
- Strong pipe. Its diameter should be slightly larger than the plate itself. The length of the product must be within five centimeters.
To make a ready-made home-made valve cracker for the VAZ as strong and durable as possible, you need to weld a small washer with a diameter of ten millimeters to the most compact bar. A pre-prepared piece of pipe is attached to the resulting workpiece. To put the structure into action, you need to fix the short bracket exclusively on the edge of the head, and install the middle part on the plate. When you press the design handle, you can quickly press the spring down, while freeing access to crackers.
Levermodel
To build a universal valve cracker, you need to prepare a classic set of tools in advance. Work steps:
- The first step is to make a lever. The rod or pipe must be bent so that it looks like lightning.
- Two through transverse holes are drilled at the short end. It is worth noting that their diameter must match the size of the bolts used.
- Short strips are ideal for making U-brackets. At the free ends, carefully drill holes for the bolts. A washer is ideal for a partition. The bracket is screwed to the extreme hole in the lever. All connections must be as strong as possible.
- At the final stage, it remains only to build from long blanks an identical bracket to the previous one, which is fixed on the lever.
A high-quality homemade valve cracker is absolutely not inferior to a classic factory unit, which can be quite expensive. A handmade tool will last for many years and save a decent amount for the family budget.
