My work history is field tech and management for Yale and Cat forklift dealerships for 30 years and the last 3 years as a customer. Looking at this from a customers view; when I need a part number for an item I sometimes use internet resources to locate the part number or, the local dealer. We also established a relationship with dealers across the country. We rely on local dealer support and if thats not there or of poor quality we might use a dealer 1500 miles away. Here is an example; our local Linde and Yale dealerships continually drop the ball whether its service; parts or product support; so we use out of state dealers or WEB orders for parts. When I worked for dealerships I never had a problem obtaining part numbers from the competition; it's all give an take on the dealership level. If you can't get along with your competition it's just going to be hard on you and not them; there will find the part numbers somewhere else; and when they do, you will lose a customer whether it's the competion or not; believe me it's easier to get along.
