Mustang Skid Steer Loader 2066 2076 2086 Service Manual (917098) – PDF DOWNLOAD

INTRODUCTION

• With correct maintenance and proper use, Mustang skid-steer loaders will give years of dependable service. This service manual is intended to be a guide in the assembly and disassembly, installation and removal, adjustment and testing, troubleshooting and replacement of components that together make up the Mustang 2066/76/86 family of skid-steer loaders.
• In many of the procedures found within, the installation steps are the exact opposite of the removal steps and vice versa, and therefore, the opposite procedure is not written. Instead, a note to reverse the procedure will be stated. This reduces redundancy and excessive pages in the manual.
• In cases though, where the assembly and disassembly or removal and installation procedures differ and additional steps or safety concerns are paramount, the entire reverse procedure will be written out to include the new information. The Table of Contents and Index can be used to make the procedure you need to find an easier process.
• Also, there are black tabs extending off the pages highlighting the chapters for those who prefer to thumb through the manual. Many schematics, photographs, and lineart drawings are used to help perform the necessary repairs, tests or adjustments that the 2066/76/86 skid-steer loaders need to keep them in good running condition.
• If you have any additional questions, please contact your authorized Mustang dealer or call the Mustang Service Department for assistance.
