Description

This 1981 GMC Light Duty Trucks Unit Repair Manual is a licensed, high-quality, PRINT reproduction of the professional manual created by the experts at the original equipment manufacturer (OEM), General Motors Corporation, for use by their dealership mechanics. Now, it can be yours!

NOTE: This is a UNIT REPAIR MANUAL (often referred to as an OVERHAUL manual). Beautifully recreated here, by publisher by Detroit Iron®, it retains ALL of the OEM content. This guide serves as the superior resource for professional mechanics, dealerships and advanced DIY restorers alike. Unlike the broader Service Manual (which covers in-vehicle service procedures), the Unit Repair Manual focuses on step by step, bench-level rebuilding and overhaul procedures regarding major components that have been removed from the vehicle.

Measuring 8.5 x 11 inches, this handsome and durable reprint is paperback bound and contains 544 pages. It's packed with detailed, factory-correct, procedures required for proper disassembly, refurbishment and reassembly of rebuildable components or units. It's filled with a variety of outstanding visual aids that have been paired with well-written text. Please check out the sample page in order to see just how well the black and white photographs complement the instructions.

You'll find this Unit Repair Manual takes you deep inside each major system. It includes complete disassembly, inspection, repair and reassembly instructions for:

Air Conditioning Compressor
Steering
Rear Axle
Front Wheel Drive
Brakes
Automatic Transmission
Manual Transmission
Clutch
Transfer Case

When tackling rebuild projects, this reproduction shop manual gives you the information and confidence to get the jobs done right.

NOTE: This is the OVERHAUL MANUAL. For the main SERVICE MANUAL, please see the 1981 GMC Light Duty Trucks Service Manual. We recommend owning all of the factory-written manuals for more complete coverage. For the main SERVICE MANUAL regarding the Caballero model, please see the 1981 GMC Caballero Service Manual.
