Repair, restoration, tuning and operational development of GBTs - one of the most hard and expensive works demanding the accuracy and accuracy of execution which independently, without the spetsialzirovanny equipment for repair gbts and skills of the professional master, to execute very difficult.
The firm "Ink Kontrakt" carries out complex (capital) repair of heads of the block of cylinders:
- recovery of geometry (planeness) of GBTs, processing of privalochny surfaces
- repair and replacement of saddles of GBTs valves
- repair and seal (welding) of cracks in a head (GBTs)
- repair (restoration) of GBTs valves
- repair and replacement of the directing plugs of GBTs valves
- repair of a candle opening of a head (GBTs) of the engine
- repair of beds (support) of the camshaft in a head of the block (GBTs)
- repair of yokes of GBTs valves
Carrying out repair of heads of the block of cylinders replacement of a large number of spare parts is, usually, necessary (for example, a belt of the gas-distributing mechanism (GRM), the bent the valve, valvate springs, etc.).
Preparing for repair of a head of the block of the engine, it is necessary to find out the reason which entailed need restoration of heads. It is necessary to understand that on removed, and even on completely sorted head of the block of cylinders, it is impossible to see a naked eye of a microcrack. If as the repair reason gbts dvs the overheat or hit of oil in the engine cooling system served, and as well as cooling liquid gases got to oil or to the cooling system, it is necessary to check integrity of a head of the block of cylinders. Pressure testing of a head is for this purpose necessary. And in the presence of microcracks - welding gbts.
At repair of a head of the block of cylinders special attention needs to be paid on the surface adjacent to the engine. In the presence of mechanical damages or roughness of a surface additional works - grinding of a head of the block of cylinders will be required, otherwise the performed work of repair of the engine will be useless, grinding of a head of the block of cylinders will be required also in cases if the engine was overheated, mechanical particles or details of small fixture got to engine cylinders at repair.
Unfortunately, repair gbts - not a panacea, and sometimes nevertheless can be necessary replacement of a head of the block. It is possible to buy a block head both new, and being in the use, but it is necessary to remember, second-hand purchase gbts can also potrebovatvosstanovleny heads of the engine.
