Foreword & Safety Note
This manual provides the service technician with all necessary data for the overhaul of Ford 6500 and 7500 Tractor Loader Backhoe units. Cleanliness is paramount when servicing the high-pressure hydraulic and transmission systems to prevent premature failure. The Ford 7500 utilizes a turbocharger to develop increased power; ensure the exhaust manifold has cooled before servicing to prevent flange warp. When performing internal engine work, always verify crankshaft end play and use correct color-coded bearing liners to maintain precise clearances.
