INTRODUCTION

This Tractor Shop Manual has been provided for qualified service personnel engaged in servicing and overhauling 1755, 1855, 1955 and 2255 Tractors. Use of this publication is not recommended for field operators since they usually do not have access to special tools and shop equipment essential for most service operations.

This manual can be used for service procedures on Minneapolis-Moline G850 and G940 Tractors. Procedures covering 1755 Tractors will apply to G850 Tractors - - procedures covering 1855 Tractors will apply to G940 Tractors.

Refer to shop manual 432 544 for service procedures on early 1755, 1855 Tractor components not covered in this manual.

Service procedures outlined herein contain sufficient information to return all component parts of a tractor to new condition. In discussion of each component part, it is assumed that a complete overhaul is being performed; consequently, complete disassembly and reassembly are outlined. The mechanic is relied upon to decide how far disassembly must be carried when complete overhaul is not required.

At tractor serial number 247 284 000, value-engineered operator's area was incorporated and resulted in component configuration changes which are not covered under Design Improvement discussions.

All parts deviations made to facilitate assembly (i. e., two thin snap rings used in place of one wide snap ring, two narrow seals used in place of one wide seal, larger or smaller diameter bearings and component parts, etc.) are not covered in this manual.

Discussions in this manual are written to cover "standard" units and this should be taken into consideration if any "non-standard" unit deviation (as outlined above) is encountered.

An issue date has been printed near lower inside corner of each page. All information is current as of issue date of page on which it is printed. For this reason, a change in design or release of a new assembly may be discussed in a recently revised group, but may not be mentioned in related discussions in other groups.

.'

Study unfamiliar service procedures thoroughly and have them well in mind before attempting disassembly. Specific data essential for proper overhaul, such as running clearances and torque values, have been provided in chart form at beginning of each group section as a ready reference for the experienced mechanic. Remember, the mark of a true craftsman is quality of workmanship.

" : Follow simple rules of safety, thoroughness and orderliness to perform service or overhaul quickly; correctly and efficiently. Keep cap screws, nuts and other small parts separated in containers according to part disassembly. Use. an absorbing compound on floor to soak up spilled oil, fuel or grease. Keep tools clean. Avoid hazardous situation!.

Reference must be made to tractor operator's manual for lubrication and service procedures which are to be performed by operator.
