This 1981 GMC Light Duty Trucks Unit Repair Manual is a licensed, high-quality print reproduction of the original factory manual created by General Motors Company for dealership mechanics. NOTE: This is a UNIT REPAIR MANUAL and is often referred to as an OVERHAUL manual. Published by Detroit Iron®, this manual was designed specifically for professional mechanics, dealerships, and advanced DIY restorers. Unlike the broader Service Manual (which covered in-vehicle service procedures), the Unit Repair Manual focused on detailed bench-level rebuilding and overhaul procedures for major components that have been removed from the vehicle.
This factory manual is 8.5 x 11 inches, paperback bound and contains 544 pages and is packed with detailedprocedures required for disassembly, refurbishment, and reassembly of rebuildable components or units.
The Unit Repair Manual takes you deep inside each major system. It includes complete dissassembly, inspection, repair, and reassembly instructions for:
- Air Conditioning Compressor
- Steering
- Rear Axle
- Front Wheel Drive
- Brakes
- Automatic Transmission
- Manual Transmission
- Clutch
- Transfer Case
Whether you're performing routine service or tackling a full rebuild, this factory shop manual gives you the confidence to get the job done right.
