Overview

The AGCO GT45, GT55, GT65 and GT75 Tractor Workshop Service Manual provides technical documentation for maintenance, troubleshooting, inspection, adjustment and component repair of these AGCO tractors. The workshop reference covers engine systems, clutch, transmission, differential, power take-off (PTO), drive axles, brakes, load-sensing hydraulics, operating controls, platform and cab assemblies, air conditioning and electrical equipment. It provides servicing specifications, component information, diagnostic references and repair procedures to support mechanical and electrical workshop operations.

The documentation includes engine timing, lubrication, fuel injection, cooling, crankshaft, piston and cylinder head servicing, together with gearbox, rear PTO and axle repair information. Hydraulic coverage includes the load-sensing power lift and distributor valve settings, while the Systems section addresses air conditioning, auxiliary hydraulics and trailer hydraulic braking. Separate electrical references identify starting and preheating circuits, instrument panel components, lighting, engine wiring and platform or cab-specific connections. The manual also provides engine assembly instructions, tightening torques, special tools and troubleshooting information for the covered systems.

Crankshaft Oil-Passage Cleaning and End-Play Measurement

The engine servicing information includes cleaning the internal lubricating oil passages of the crankshaft and cylinder block after overhaul operations have been completed. These passages must be cleared of deposits and contaminants before engine reassembly. The supplied servicing instructions describe using diesel fuel or compressed air to clean the passages, with appropriate workshop precautions. This cleaning is important because material remaining inside the lubrication circuit can interfere with oil flow or damage serviced engine components.

Crankshaft end play is checked using a dial indicator mounted on a magnetic base against the crankcase. The indicator contact is positioned against one end of the crankshaft, which is then moved axially in one direction before the indicator is reset. Moving the crankshaft in the opposite direction provides the end-play reading. The supplied procedure specifies a clearance of 0.004–0.010 in (0.10–0.27 mm). If the measured clearance exceeds the applicable limit, the instructions identify oversize thrust half-rings of 0.004–0.008 in (0.10–0.20 mm) above nominal thickness as a corrective option. Confirm the relevant engine configuration and service specifications before selecting replacement components or carrying out adjustments.
