Bobcat MT52, MT55 2007 Service Manual

If you’ve sunk hours into a Bobcat MT52 hydrostatic pump rebuild only to find the charge pressure is off because you guessed the spec, you understand why this 2007 factory manual matters. This is the original dealer copy—the same document Bobcat technicians used. At 397 pages, it covers both the MT52 and MT55 mini track loaders. No aftermarket shortcuts. No generic diagrams. Every torque value, every fluid capacity, every test procedure came straight from the assembly line.

Foreword and Safety Instructions: Not Optional Reading

Before you touch a wrench, read the safety instructions on page 1. The manual warns about hydraulic fluid injection, battery acid burns, and the absolute rule: never work under raised lift arms without an approved support device. Fire prevention is covered, including cleaning flammable materials off the engine before checking fluids. These aren’t lawyer disclaimers—they’re the same warnings that keep Bobcat techs alive. The manual includes the safety alert symbol definitions and a list of incorrect vs. correct practices shown in photographs.

7 Systems Covered in Depth

This Service Manual breaks the machine into seven major sections: Engine Cooling System, Fuel System, Engine Lubrication System, Hydraulic System, Hydrostatic System, Electrical System, and Drive System. Each section starts with a troubleshooting chart. For example, the Hydraulic System contains a Workgroup Troubleshooting Chart and specific Hydraulic Function Troubleshooting (e.g., cylinders won’t lift). The Hydrostatic System includes a dedicated troubleshooting chart for charge pressure issues and replenishing valve function.

Hydraulic Cylinder Procedures: Disassembly and Assembly

The Lift Cylinder and Tilt Cylinder sections give parts identification, removal and installation steps, and full disassembly/assembly procedures. The Rod End Pivot Pin Bushing and Seal Replacement is covered for the tilt cylinder. These procedures list the tools required—ball peen hammer, seal driver, shop press—and torque values for gland nuts. The manual does not skip the step where you check cylinder drift before pulling it apart, a common mistake that leads to unnecessary seal replacements. For the related Bobcat MT52 Service Manual and the Bobcat MT52 MT55 2008 Service Manual, these procedures remain consistent across model years.

Hydrostatic System: Checking Charge Pressure and Replenishing Valves

Charge pressure is the lifeblood of the hydrostatic drivetrain. The manual gives the procedure to check it using a pressure gauge on the charge pressure sender port. It also covers replacing the poppet assembly and disassembly/assembly of the hydrostatic pump, including the replenishing/high pressure relief valves. If you don’t have the factory spec for charge pressure, you’re guessing—and guesswork turns a seal kit into a pump replacement. The Bobcat S175 2008 Service Manual – OEM Factory Repair Specs uses the same fundamental logic, but this MT52/MT55 manual has your specific drive motor and pump part numbers. For general knowledge on gear-based power transfer, see Manual Transmission fundamentals—different technology, but the same need for precise clearances.

Authenticity: Dealer Copy, Not Aftermarket Reprint

Look at the first page: “Printed in U.S.A. – Bobcat Company 2007 – Dealer Copy – Not for Resale.” That’s the OEM stamp. This is not a scanned third-party compilation with fuzzy diagrams and misaligned torque tables. The original file is 397 pages of vector drawings and factory typed text. Aftermarket manuals often omit the serial number location tables—this one includes both Loader Serial Number and Engine Serial Number procedures. If you’re used to aftermarket handbooks that say “tighten to spec” without giving the number, you’ll appreciate the difference. For a deeper dive into how gear-driven transmissions work, Manual Transmission resources can supplement your knowledge, but this manual is your primary source for the Bobcat hydrostatic system.

Does this manual cover the MT55 model?

Yes. The manual covers both MT52 and MT55, including all serial number ranges listed.

What about the electrical system?

It includes a full Electrical System section with fuse and relay location/identification, battery terminal cleaning, jump starting procedure, and battery removal/installation. The description covers the 12-volt system layout. There’s also coverage of the Neutral Start Interlocks and Reverse Stop Panel in the Controls section.

You don’t need another generic PDF. You need the actual factory sequence—the same one Bobcat used to train its own technicians. That’s what this is. Click the link below to access the factory manual.
