Known issues on the 1990 W7500 Tiltmaster. The federal record holds no recall for this year and no complaint from an owner, which makes the engine range the thing worth dwelling on. Three diesels means three sets of clearances, torque figures and injection values, and the manual keeps them distinct so a specification is never applied to the wrong displacement. Around them, the chassis and body sections supply procedures, torque values, wiring diagrams and diagnostics for a truck that is otherwise identical between the two codes.
