ENGINE REBUILD

Engine rebuilding is a complex task, regardless of the brand of the car engine, its success and long mileage depend on quality work and the right expertise!

elements of our service

Connecting rod machining

One of the most important parts of the crankcase is the connecting rod. The conrod transforms the vertical movement caused by the explosion into a rotating movement on the crankshaft. Connecting rod drilling helps to save unique and expensive faulty crankshafts, because redrilling does not require us to buy a new conrod when rebuilding an engine. Conrod drilling is a work process in which the failed, worn hole is re-drilled and a new bearing is placed in the connecting rod. Another method of drilling the conrod is grinding from the ring fitting point of the disassembled semi-circle from the side mounted on the conrod. During assembly, the slightly elliptical inner hole is re-drilled to the factory size.

Cylindrical drilling on a CNC engine block machining center

In the engine block, the pistons move in the cylinders. Over time, due to movement, the cylinders may crack or wear out due to material defects, under-design, overload due to tuning, improper lubrication...

In such cases, cylinder drilling is the best solution. We have several options for cylinder renewal. We drill out the cylinder to a larger diameter, thus removing the defective surface, and then install pistons of a correct size in the block. Or we machine the cylinder to such a radius that we can press a cylinder bushing into it, so a completely new, perfect surface is created and we can use the basic size pistons again.

Cylinder drilling is performed using CNC technology. In engine restoration work, cylinder drilling must be followed by a honing process, so that the cylinder wall has a special surface when honed, which helps to maintain compression, and at the same time provides adequate lubrication for the sidewall of the piston.

Crankshaft grinding

The crankshaft is the part of the crankcase that converts the linear movement of the pistons into rotary movement with the help of the cranks and transmits it to other parts of the drive chain. Defective crankshafts undergo a multi-step renovation process in our workshop. First of all, we determine the condition of the material surface of the part. We use a magnetic crankshaft crack testing machine to determine whether microcracks are present. If there is deformation in the line of the crankshaft, we straighten the crankshaft with a special hydraulic, high-pressure device. By grinding and polishing the pins of the crankshafts, we create a component with a suitable surface again. Since the diameter of the main shaft's fulcrum and crankpins has decreased, oversized bearings are required. Crankshafts are very expensive parts, so if the condition of the failure still allows for renovation, it is worthwhile to restore the part.

Line drilling

Line drilling is a work process during which we machine the shaft housing holes of the camshafts of the cylinder heads and the main shafts of the engine blocks. The line drill is capable of re-drilling serial holes with an accuracy of hundredths of a millimeter. The holes are made with a special line drilling machine, which is suitable for making holes on exactly one axis.

Engine inspection price

Engine overhaul is a complex task that requires a high level of precision. Due to the complexity of engines and the countless types of failures, many problems can occur in their operation. Therefore, the very first step in any engine overhaul is fault detection. In our workshop, the engine undergoes an inspection before providing a quote, so that we can get an accurate picture of its condition. We only provide a quote after the fault has been identified, so that you can be clear about the costs of the overhaul.

Inspection steps:

Transport
For the convenience of our customers and the efficiency of the renovation, we work with great flexibility, which is why renovations can also be requested with delivery in our workshop! We send a contracted courier service for the package, but we can also arrange the delivery of larger, pallet-sized engines.

The inspection fee in our workshop, depending on the size and condition of the engine, starts from a symbolic net 45,000 HUF compared to the size of the work. Of course, this amount may be higher for commercial vehicles, larger or more complex engines. The price quote includes the fee for the entire disassembly, washing, pressure testing and inspection process, so if you accept our offer for the renovation, you will no longer have to pay these fees. In the case of individual delivery, the inspection fee will be increased by the cost of delivery.

Frequently asked questions before engine overhaul

How much does an engine rebuild cost?

The cost of an engine rebuild depends on many factors, including the type of engine, its condition, and the extent of the repairs required. A minor repair may cost less if only a few parts need to be replaced or rebuilt, while a full rebuild can cost significantly more. The price also depends on the extent of the damage; the more work required to rebuild the engine, the higher the cost of the rebuild. The exact extent of the engine failure will be determined during a full inspection. The inspection will also reveal problems that are not visible to the naked eye. We can only provide a price after a thorough inspection, so there is a much lower chance of additional costs arising during the engine rebuild.

DELIVERY OPTIONS

from anywhere in the country
For larger truck and agricultural cylinder heads, transportation can be a serious logistical issue, but our workshop offers a solution to this problem too!

If necessary, our workshop will ensure that the cylinder head to be reconditioned reaches us easily. Our door-to-door delivery service simplifies the commute involved in reconditioning for you. If necessary, we will collect the part requiring reconditioning from your premises and return it to you once the work process is complete.
Several methods of transportation are possible.

The primary and most flexible solution for sending parcels is the service of GLS, MPL or Raben. The parcel must be assembled according to the rules applicable to these services. Only clean, oil-free parcels are accepted for delivery, packed in boxes. Larger, palletized goods are delivered by the courier service MPL or Raben.

We also handle the transportation of special or heavy cylinder heads. Our workshop has several vehicles reserved for this purpose. If it is not possible to arrange for a courier service to deliver the package, in some cases we will use our own vehicle to pick up the engines that need to be renovated. Our fleet has different types of vehicles available for the transportation of cylinder heads of different sizes, so large shipments are not an obstacle.
