Bobcat MT52, MT55 2008 Service Manual – Factory Repair Specs

I’ve seen guys waste a whole afternoon guessing on a hydraulic pressure check because they had some third-party printout with missing values. That doesn’t happen with Bobcat MT52, MT55 2008 Service Manual. This is the factory service manual – 388 pages of the exact procedures Bobcat wrote for their own techs. Not a photocopy. Not a reprint. Original OEM release from 2008. Covers serial numbers A3WR11001 and above, A3WT11001 and above, A3WS11001 and above, A3WU11001 and above for both the MT52 and MT55 Mini Track Loaders. If you’re working on one of these machines, this book keeps you from guessing.

Fire Prevention and Electrical Safety – Page 2

Page 2 lays out the safety instructions that apply to every job. Fire prevention is broken down by system: Maintenance, Operation, Electrical, Hydraulic System, Fueling, Starting, Spark Arrestor Exhaust System, Welding And Grinding, and Fire Extinguishers. The electrical section is particularly important – lead-acid batteries produce flammable and explosive gases. The manual tells you exactly what precautions to take before you even open the hood. I’ve seen techs skip this and regret it. Read it.

Does the Bobcat MT52 MT55 2008 Service Manual Cover the Engine?

Yes. The Engine Lubrication System chapter covers checking and adding oil, oil chart, and removing/replacing oil and filter. The Engine Cooling System gives cleaning procedures, level checks, and coolant removal/replacement. Fuel System section includes fuel specifications (including biodiesel blend), filling tank, fuel filter replacement, and removing air from the system. The engine serial number location is documented. For the engine itself, you get procedures for air cleaner service, spark arrestor muffler cleaning, and pivot pin inspection. If you need to pull the engine, the manual doesn’t cover full engine overhaul – this is a service manual, not an engine rebuild guide. But for routine service and troubleshooting, it’s complete.

3 Critical Systems: Hydraulic, Hydrostatic, and Drive Belt

The hydraulic/hydrostatic system gets the most pages. You’ll find hydraulic/hydrostatic schematics, troubleshooting, and component procedures for the lift cylinder, tilt cylinder, main relief valve, port relief valves, hydraulic control valve (with identification chart and disassembly/assembly), hydraulic pump (direct pump testing, removal/installation, parts ID, disassembly/assembly), filter housing, fluid reservoir, and oil cooler. The hydrostatic system covers the motor (disassembly, inspection, assembly), charge pressure testing and sender replacement, hydrostatic pump (with replenishing/high pressure relief valve), and drive belt adjustment, alignment, and tensioner pulley service. The steering control panel and linkage adjustments are also included.

Get the Right Torque Data – Without Guessing

Every fastener torque value appears in the procedure that uses it. You don’t have to flip to an appendix. The cylinder disassembly and assembly sections list specific torque for rod end pivot pin bushings. The hydraulic pump assembly gives torque for housing bolts. The hydrostatic motor assembly includes torque for the case bolts. If you need charge pressure spec, it’s in the charge pressure testing procedure. This manual does not leave you guessing. If you’ve ever had a main relief valve leak because you used a generic torque spec from an online forum, you know why this matters.

Source Authenticity: OEM Factory Print from Bobcat

I distrust aftermarket documentation. This is the real thing – printed by Bobcat Company in 2008. The foreword and delivery report sections confirm it’s a dealer copy. The manual includes serial number location for both loader and engine, delivery report, and loader identification. Every illustration uses Bobcat part numbers and correct safety alert symbols. The hydraulic/hydrostatic schematics are factory originals. If you need a manual you can rely on in a shop environment, aftermarket won’t cut it. This one will.

Related manuals: If you need earlier model year data, see the Bobcat MT52 MT55 2007 Service Manual. For a single-model version, the Bobcat MT52 Service Manual focuses on that model. Looking for a different machine? The Bobcat S175 2008 Service Manual – OEM Factory Repair Specs covers the skid-steer line. For reference on standard Manual Transmission repairs, the torque specs differ – but this manual covers hydrostatic drive only. Also compare with Manual Transmission procedures for other equipment.

Is this manual for MT52 and MT55 both?

Yes. Covers both models and serial number ranges listed.

Does it include wiring diagrams?

The manual includes hydraulic/hydrostatic schematics, but the Electrical section within the Safety Instructions covers fire prevention and electrical safety precautions. For detailed wiring diagrams and component testing of the electrical system, you should reference the dedicated Bobcat electrical service manual. However, this manual does cover neutral start interlocks, continuous flow shutoff lever inspection, and auxiliary hydraulic interlock deactivation – all of which involve electrical switches and circuits. Also covers the reverse stop panel operation and inspection, which involves electrical limit switches. Additionally, the lift and tilt function lockouts section includes inspection of electrical controls.

What pages have torque specs?

Torque values are listed throughout each component section. For example, cylinder disassembly and assembly includes fastener torques. Page 2 has safety warnings.

Can I use this if I’m a home mechanic?

Yes. The manual is written for service technicians but the step-by-step procedures are clear enough for an experienced DIYer. Follow all safety warnings.

If you’re serious about keeping that Bobcat running right, stop relying on forum posts and pirated PDFs. Access the Factory Manual and get the actual specs that Bobcat engineers wrote.
