Foreword
This service manual provides instructions for troubleshooting, removal, inspection, replacement and overhaul of 1977, 1978, 1979, 1980 and 1981 Model 150 VERSATILE Tractor components. The service manual should be used in conjunction with the parts manual for the specific model year. A table of contents precedes each section providing detailed coverage of the information contained within that section. The index at the end of the book should ease location of specific information, and an up-to-date list of Perkins Distributors is provided following the index. The purpose of a loose-leaf service manual is to enable us to keep the book updated. When changes are made, pages will be forwarded to you marked either as replacement or additional pages.
