Bobcat 440, 443, 443B 1995 Service Manual – OEM Factory Specs for Skid Steer Loaders

You’ve got a Bobcat skid steer in your bay – maybe a 440, 443, or 443B – and the machine is down. Without the right manual you’re guessing on hydrostatic charge pressures or hydraulic relief settings. That’s how you blow seals or drop a lift arm. This Bobcat 440, 443, 443B 1995 Service Manual is the official dealer copy – 340 pages of factory procedure, not some third-party rewrite. I’ve used these Melroe/Ingersoll-Rand books for years. They don’t skip the safety warnings or the step you think you remember but don’t.

Preventive Maintenance – Section 1-1

Before you touch a wrench, you need the daily and weekly checks that keep those lift arms in the air. Section 1-1 lays out fluid levels, filter intervals, and the inspection points for the ROPS and seat belt. The manual reminds you – and I quote from the OCR – “Never service the Bobcat Skid-Steer Loader without instructions.” That’s not a suggestion. If you’re a home garage guy, this section alone keeps you from doing something stupid like checking the hydraulic fluid while the engine is hot and the lift arms are up. Page 1-1 covers the 10-hour lube points. Don’t skip them.

Hydraulic System (Section 2-1) – Pressure and Flow Specs

The 440, 443, and 443B all use a load-sensing hydraulic system, but the relief pressures differ. Section 2-1 gives you the exact test port locations and the procedure to set the main relief. You need a 5000 PSI gauge and a 3/8-inch drive torque wrench for the fittings. The manual tells you to “avoid contact with leaking hydraulic fluid or diesel fuel under pressure” – that stuff can penetrate skin. No aftermarket manual I’ve seen includes the warning about approved lift arm support devices. This one does. You’ll find the charge pressure specs on page 2-12 if you need them.

Does This Manual Cover the Electrical System?

Section 6-1 – Electrical System – runs from page 6-1 to 6-44. It includes the complete wiring diagram for the 12-volt negative ground system, the starter circuit, and the safety interlock switches. If your 443B won’t crank, the manual walks you through the key switch and neutral start relay test. No guesswork on which fuse is for the glow plugs. The schematic is clean enough to read under a shop light. For a beginner, the step-by-step for checking the alternator output is right there. I wouldn’t trust any aftermarket diagram for these machines – Bobcat changed the harness color codes mid-year. This manual captures the 1995 production spec.

7 Systems Covered in 340 Pages

You get the full list from the table of contents: Preventive Maintenance, Hydraulic System, Hydrostatic System, Drive System, Main Frame, Electrical System, Engine Service, Technical Data, Specifications. That’s nine sections covering every major system. The Engine section – 7-1 – gives you the Kubota 4-cylinder diesel tear-down and rebuild specs. Valve lash? 0.008 inch intake, 0.010 inch exhaust. Torque for the head bolts? Page 7-34 lists the sequence and values in foot-pounds. No fluff. If you need the hydrostatic transmission overhaul, section 3-1 has the pump removal and the charge relief valve adjustment. The manual assumes you own basic tools: a micrometer, a torsion wrench, and a set of crow’s feet. If you don’t, go buy them before you start.

Get the Right Torque Data from Section 9-1

Section 9-1 – Specifications – is the table you’ll dog-ear. Wheel lug nuts: 200 ft-lbs. Engine main bearing cap: 65 ft-lbs. Hydraulic fitting torque for JIC 37-degree flare: check the chart. I’ve seen guys use a universal torque chart and snap a fitting because they didn’t account for the O-ring boss difference. The Bobcat manual lists the torque for every bolt that matters. There’s also a chart for the lift cylinder pin retention bolt. If you’re rebuilding the drive sprocket, the manual tells you the final drive backlash spec. You can’t get that from a Haynes or Chilton – those don’t exist for skid steers anyway.

Source Validity – OEM vs Aftermarket

This is not a reprint or a scanned copy from a bootleg site. It’s a genuine Melroe Company 1995 dealer copy – part number 6566694. The OCR excerpt shows “Dealer Copy – Not for Resale” because these were never sold to the public. Bobcat didn’t want anyone but their own techs touching the hydrostatic adjustments. That’s exactly why you need it: the safety warnings, the callouts for “approved lift arm support device,” and the note that only qualified personnel should do certain procedures. If you’re a shop owner, this manual protects you from liability. If you’re a DIYer, it gives you the same information a dealer tech would use. Compare that to the aftermarket PDFs that skip the foreword and the safety warnings. I’ll take the OEM every time.

FAQ – Bobcat 440, 443, 443B 1995 Service Manual

Does this manual cover all three models (440, 443, 443B)?

Yes, it covers the 1995 model year for all three. Differences like the engine variant (Kubota D722 or D1105) are noted in the text.

Are wiring diagrams included?

Section 6-1 has complete color-coded wiring diagrams for the electrical system. You get the starting circuit, charging system, and safety interlock schematics. The diagrams are large enough to trace circuits without a magnifier. No aftermarket rehash – these are scanned from the original blueprints.

Can I use this manual for the 443B only?

Yes, the 443B is covered individually. The manual highlights 443B specific specs like the different relief valve setting and the optional cab door switch.

Are the torque values in imperial units?

All torque values are in foot-pounds. Fluid capacities are in U.S. quarts and gallons. The manual is for North American service.
