FAQ - Frequently Asked Questions
-
#1.Where to start?
The first step is to contact Łukasz, our coordinator for internal combustion engine repairs. You can call +48 33 870 42 15 or use the contact form available on our website.
-
#2.How to deliver a combustion engine for repair?
You have several convenient options to choose from:
- Personal delivery to our workshop.
- Sending the engine by courier.
- We can also arrange for a courier to ship the engine on a pallet from a specified location, and after the repair service is completed, the courier will deliver it back.
- If you lack the appropriate facilities for disassembly or assembly, our mobile service can come to you and perform these services on-site. -
#3.How does the engine repair process proceed?
Our engine overhaul process is thorough and transparent:
- Detailed verification: the engine is disassembled down to the "last screw" and subjected to a detailed verification.
- Cost estimate and schedule: we prepare a comprehensive cost estimate and determine the expected repair time.
- Major overhaul: upon your acceptance of the terms, we proceed with a comprehensive repair, which is always a major overhaul, not just a replacement of individual components.
- Testing and painting: The overhaul is completed when the engine successfully passes tests at the engine dynamometer station. The final stage is professional engine painting. -
#4.What will you find in our offer?
We always strive to present you with the most beneficial solutions, therefore depending on the availability of spare parts you will receive:
- An estimate for repair with original parts.
- An estimate for repair with high-quality spare parts.
- As an alternative, we can propose purchasing the same refurbished engine from our warehouse, which often significantly shortens the completion time. -
#5.How long does it take to repair a combustion engine?
- The verification of your engine will take us 1-3 days from the moment of delivery.
- You will receive an estimate for typical repairs within the next business day after the verification is completed.
- The repair itself usually takes about 3-5 weeks. -
#6.How do we test combustion engines?
Every refurbished engine undergoes rigorous testing on our engine dynamometer. The unit is loaded in a way that simulates operation in a construction machine. During the tests, we check key parameters such as:
- Power and torque performance.
- Coolant and oil temperature.
- Oil pressure depending on its temperature.
- Behavior and performance changes in relation to load.
The entire test lasts on average from 12 to 24 hours, depending on the specifics of the engine. -
#7.How can I be sure that the engine will work after the repair?
We care about the highest quality:
- We perform repairs exclusively on high-quality parts, and assembly work is always in accordance with the specification of a given engine.
- After the repair, the engine is thoroughly tested. The test result is always available in the form of a readable chart.
- You will receive a 12-month warranty for each repair. In case of questions regarding assembly or operation, we encourage you to use the expert knowledge of our sales advisors through a phone call. -
#8.Can I cancel the repair after receiving the estimate?
Yes, you can cancel the repair without any costs after receiving the estimate and before accepting it.
-
#9.How much does it cost to repair my engine?
The cost of repair depends on several factors: the engine model, the degree of its wear and tear, and the scale of damage. Very often we can only provide an approximate price range, based on our history of similar repairs.
