Troubleshooting a dead charging system or rebuilding the lift arms on your Bobcat 310 or 313 Skid Steer Loader requires exact factory specifications. This 192-page manual (OEM #6556606) breaks down every major system and both engine variants. Complete fluid routing appears in the hydraulic and hydrostatic schematics, alongside wiring diagrams paired with charge system service procedures. Troubleshooting charts isolate electrical, hydraulic, and engine faults quickly. Step-by-step procedures and exploded views cover drive system repairs, Bob-Tach removal, and full engine rebuilds for both powerplants. The 310's hydraulic system holds 8 gallons (30.3 L); torque the wheel bolts to 45-55 ft.-lbs. (61-75 Nm) before putting the machine back in service. Bookmarked and keyword-searchable, it works on a tablet at the machine.

Bobcat 310, 313 Common Problems This Manual Covers
Loader functions are weak or bucket takes too long to lift under load p. 44
Time the lift cycle. If the load cannot be raised to full height in 8 seconds or less, check page 44 for relief valve settings. Test the system to confirm the hydraulic relief pressure reaches 1200 PSI (8274 kPa). Inspect piston seals for leaks and verify correct drive belt tension.
Manual Section: Hydraulic SystemAttachment does not lock securely and shows excessive movement at the Bob-Tach plate p. 73
Examine the Bob-Tach wedges on page 73 and replace them if worn or damaged. Verify the wedges move to the full lock position when the lever is engaged. Torque the Bob-Tach pivot bolts to 160 ft-lbs (217 Nm) and check the linkage for excessive play.
Manual Section: Main FrameBattery constantly goes dead or machine will not charge properly during operation p. 21
Measure the battery electrolyte level as shown on page 21 and add water if needed. Clean the cables and connect the ground cable last. Test the battery to verify it produces 270 cold cranking amps at 0°F (-17.8°C). Smell the sealed rectifier/regulator unit for odors indicating a defect.
Manual Section: Electrical SystemEngine performance degrades under load or shuts down entirely after running for several minutes p. 149
Drain and flush the fuel system, then refill the tank to its 5.5 gal (20.8 L) capacity as noted on page 149. Check the governor to ensure the engine reaches a maximum governed speed of 3000 RPM. Clean the dry replaceable paper air cleaner element.
Manual Section: Engine (310)Frequently Asked Questions
What are the torque specs for Bobcat 310/313 wheel bolts?
The wheel bolts for the Bobcat 310/313 should be torqued to 45 - 55 ft.-lbs. (61 - 75 Nm). This specification is crucial for proper assembly and safety.
How do you bleed the fuel system on a Bobcat 310/313?
To remove air from the fuel system on a 313 engine, loosen the plug on the injector pump (Fig. 7—2a, Item 1), turn the key switch to "ON" to activate the electric fuel pump, and then tighten the plug after fuel is free of air. If air remains, loosen the pipe nuts on the injector nozzles (Fig. 7—2b, Item 1), turn the switch key to "START" to turn the engine, and continue until no air comes from the loosened pipe nuts. The 310 engine uses a carburetor and does not have injector nozzles for bleeding.
How do you adjust the drive chain or speed control on a Bobcat 310/313?
To adjust the clutches, which control forward and reverse movement, ensure the steering levers do not move more than 3 inches in either direction from neutral. Loosen the 3/8" locking nut and the 5/8" nut one turn, then turn the clutch adjustor to permit the steering lever to move 3" from center. For the final drive chain, check tension to be about .25 inches (6.35 mm) of movement with finger pressure at the center of the upper span, and adjust by loosening holding nuts and moving the final drive idler toward the rear.

Document Quality
This is a scanned PDF document with an OCR layer, so you can search the full text and copy content. The text quality is generally crisp and readable, although some pages show minor fading or slight skewing typical of scanned materials. Diagrams and illustrations are raster images; they are clear enough for labels to be read, but they will pixelate if zoomed in significantly. Pages are mostly clean, but you will find occasional small scan artifacts or smudges, and there are numerous blank pages interspersed throughout the document, likely serving as dividers or filler.
