Reconditioning of pistons MAK M551 cause trouble ?Retech is an old hand at it. To avoid  build ?up welding and defects because of this ,Retech  got a new technology: casting new top of the piston[aluminum and cast iron part]

The beautiful season -golden autumn has come  in Varna ?Retch office ? a nice old house , covered by blue flowers- looks like a strange house from the folk tales  

The 20 years from  the company RETECH  foundation  were turned in may 09. The event was marked with company party, it had happened in an restaurant -ethnographic complex near Varna.

Most specialists say that camshafts are parts ,which  reconditioning by build-up welding is impossible-at least very difficult; about camshafts ,made by cast iron this is something unthinkable. But good  technology gives opportunity to resize journals with wearing out beyond  possibilities of the plating technologies. RETECH?s reconditioned first auxiliary engine camshaft Sulzer 5AL25/30  has been working since1993 ;another four were made after this and lots of air-compressors  camshaft also: all of them to the original dimensions.
