We have been working with Power Tech for many years. They do all our hydraulic pump rebuilding and we get valves through them. The workers are always helpful, professional and just great. Their pricing seems in line. It may be a little higher than average but it's certainly worth it because they are easy to in contact with and can be reached by phone to get answers. Their service used to be a 5 but they shut down their shop in New Jersey and moved to Pennsylvania so the turnaround time is longer than it used to be. Other than that their services are great.
