When an engine fails, the question arises: repair or buy a new one? Let's look at an economic calculation that will help you make the right decision.
When repairs are more profitable
- Engine power over 7.5 kW - repairs are usually 2-4 times cheaper than a new one.
- The engine is rare or out of stock.
- The stator iron and shaft are in good condition.
- Urgency is needed - repairs are faster than delivery new.
When replacement is more profitable
- The stator iron is damaged (irreversibly).
- The engine is low-power and cheap - repairs are comparable to the price of a new one.
- The cost of repairs is approaching 70% of the price of a new car.
- It makes sense to switch to an energy-efficient engine (IE3-IE4).
Rule 70%
| Repair cost | Solution |
|---|---|
| Up to 50% of the price of a new one | Repair is definitely profitable |
| 50–70% | Depends on condition and timing |
| Over 70% | It is worth considering a replacement |
What to consider additionally
When calculating, take into account not only the price, but also the delivery time of the new engine, its efficiency (electricity savings) and service life after repair. Often high-quality rewinding returns the engine to almost its factory resource. An accurate calculation is possible after diagnostics.
