I did NF Lucas on a Volvo d12c. I came for repairs from the Krasnodar Territory on the recommendation of a friend. The guys are real experts in their field, which is very rare to meet now. I recommend it to everyone.
He repaired injectors for Chinese special equipment sdlg, lonking, front loaders, and x3000 miners. It was done quickly and efficiently. Prices are lower than in Voronezh.
