So my Yale tech at Pape Material Handling told me that this AISAN unit cannot be rebuilt and that I would have to buy a whole new unit for $830! So of course as a welder having rebuilt countless pressure regulators, I looked into it and found a few rebuild kits for these AISAN units. And when I told them that I was going to rebuild my AISAN unit, they wanted to charge me over $200 for the rebuild kit when the most expensive one I found online was $93. But what bothers me the most is how quick they went from telling me that I needed to buy a new unit to trying to sell me the rebuild kit. And of course there is the fact that they wanted to charge me $830 when they go for about HALF that. I am starting to think that this outfit is a joke. I will give them the benefit of the doubt, pay one of their techs ONCE to come out, work with the tech on everything that the tech does while the tech is here, and form an opinion after the tech tells me his opinion on this bulls%&t. I mean, I EXPECT shady practices from auto shops, but from a lift truck DEALER? Wow...just...wow.
