Just purchased a Bil Jax 45 xa and have a few questions. There is a salami hydraulic dual pump, part number A01048, that is not working properly at roughly $1500.00 replacement price. Was wondering if these can be rebuilt or are there other options for repair that would not be that expensive. Was also wondering if there is a factory service manual with more detail than the online manuals and the hard copy owners manual that came with it. Looking for detailed electrical schematics and more detailed repair manual. I assume they have these at the factory but I see nothing available anywhere on line. Anyone out there familiar with these units, I'd like to hear from you. Thanks
