When to check them
Mechanical injectors are used on older diesels, farm machinery and generators. Signs of wear: smoke, hard starting, rough running and higher fuel use.
What we do
On the bench we check the opening pressure, spray pattern and needle sealing. We replace nozzles, set the opening pressure with shims or a screw, and re-test the whole set so all injectors work evenly.

FAQ
How do I send parts for repair?
Remove the pump or injectors, plug the openings, pack them tightly and ship via Nova Poshta. Add a note with your phone number and car model. See the Delivery & payment page for details.
Do you give a warranty?
Yes, on the work done and installed parts. The terms are stated in the report.
When will I know the price?
After the bench test we call you to agree the price. We never start a repair without your approval.
Why check the turbocharger, injectors and pump together?
The turbocharger, injectors and high-pressure pump work as one system. Worn injectors flood the cylinders with excess fuel, which overloads the turbocharger. A worn pump contaminates the whole fuel system with metal shavings and damages the injectors. A faulty turbocharger delivers the wrong boost, so the engine runs with the wrong air-fuel balance. Repairing just one part often means the problem comes back, so we recommend having these units checked together: on the bench we find the root cause instead of only fixing the symptom.
What should I do if I notice signs of a fault?
Don't put it off: a small fault quickly becomes an expensive one. Don't rely on “miracle additives”: they don't restore worn parts. Don't drive if you hear grinding, see heavy smoke or the oil pressure drops. Get in touch: we'll advise you, test the removed parts on the bench and tell you honestly whether a repair is needed and which one.
