This factory service and repair manual for the 1987 Chevrolet W7500 Tiltmaster serves a low tilt straight truck cataloged as W7R042 and listed with either of two turbocharged diesel sixes — the 8.4-liter of 513 cubic inches or the 5.8-liter of 353. Identifying which is fitted is the first step of any engine job here, because the torque values, clearances and injection specifications diverge from that point. The frame, driveline, brake, steering and electrical sections are common to both.

Known issues on the 1987 W7500 Tiltmaster. No recall action and no owner complaint attach to this model year on the federal record. The manual therefore reads as a working reference rather than a caution list. Both engines are covered through their mechanical, fuel, air and cooling systems with the numbers each takes; the driveline and chassis are given procedures and torque values of their own; and the diagnostics move from symptom to circuit with the wiring diagrams printed close enough to be used in the same sitting.
