I cannot recommend this company
I have been driving truck for 35 years, and this REPAIR has been the worst experience I have ever went through, I brought my truck in after a major repair with a different mechanic, that mechanic replaced my heads and injectors on my Cummins N 14, after the repair I noticed that the engine was smoking badly, so I brought it into Guy Robertson with tractor center, all I asked him to do was diagnose and repair the smoking and install new air conditioning parts, which I supplied, by the time of pick up, they had sent out my ECM to get reprogrammed and repaired, did a timing adjustment on the motor and installed the air conditioning parts which took them over a month and a half. Another item that guy suggested we change out was the new injectors., so I asked him how much they would be, he said $1437, I asked him for each or for all of them, answered for all of them, so I said, order them, the injectors alone added up to over $8000 for six injectors, I could’ve got them for $500 apiece from Cummins or Kenworth.
My final bill was $18,000 I could’ve had my motor rebuilt for a little over that.
The worst part is, is the truck is still smoking!
