Wrenching on an old Case crawler? This 974-page Case 310 Service Manual PDF (OEM #9-99772) covers the 310, 310G, and 350 crawlers, from the 188 diesel and 148 spark-ignition engines down to the final drives. Inside: factory wiring diagrams, hydraulic schematics with pressure check procedures, troubleshooting charts for the power shuttle transmission, and rebuild steps for the Intertrac track and suspension system. You also get full sections on mounted equipment: loaders, dozers, winches, rippers, and the Model 26, 32, and 33 backhoes. Set fan belt deflection at 1/2 inch, torque the lower mounting bolts to 22-30 foot pounds, and swap filters every 500 hours. These crawlers outlived their paper manuals decades ago. This scanned factory PDF is bookmarked by section, opens on any device, and walks to the machine with you.

Case 310G, 350, 310G-350, 310 Common Problems This Manual Covers
Case 310G loader hydraulics slow and weak, bucket drifts down under load
Check hydraulic oil level first; low oil pulls air into the suction line and makes every circuit spongy. Replace the 40 micron return filter element, page 399 calls for service every 200 hours. Then run the pressure checks in the hydraulics section starting on page 397 to isolate a worn pump from a leaking relief valve.
Manual Section: Hydraulics p. 399Engine overheats and pushes coolant when dozing uphill, temperature gauge pegs within minutes
Check coolant level cold, then inspect the radiator core for packed chaff and mud; blow it out from the engine side. Verify fan belt deflection at 1/2 inch by hand pressure, page 305 shows the check. A loose belt slips under load and drops airflow. Work through the overheating steps in the engine diagnosis section.
Manual Section: Engine p. 305Diesel hard to start, stalls under load, loses power right after refueling
Drain the sediment bowl and check for water before anything else. Replace the primary and final fuel filters, page 330 calls for new elements every 500 hours or sooner when power drops off. Bleed air at the filter housing and injection pump until fuel runs clear with no bubbles, then retest under load.
Manual Section: Fuel System p. 330Track keeps coming off on side slopes, undercarriage clanks and squeaks at low speed
Check track tension first; a loose chain derails on slopes and an over-tight one eats pins and bushings. Inspect rollers and idlers for flat spots and leaking seals, then check sprocket teeth for hooking. If you press new roller shaft bushings, size the bore to 1.7525 to 1.7550 inches after pressing, per page 592.
Manual Section: Track and Suspension p. 592Battery dead every morning, ammeter shows discharge, belt squeals at full throttle
Test battery voltage and clean both cable terminals before condemning the alternator. Check belt tension with a gauge: 80 to 90 pounds for a used belt, or 1/2 inch deflection by hand, page 780 covers the adjustment. Load-test the charging circuit afterward to confirm output.
Manual Section: Electrical p. 780Frequently Asked Questions
What are the replacement specifications for engine air filter elements?
The air cleaner is a dry type with a built-in pre-cleaner. The filter element should be cleaned or replaced when the air restriction indicator shows a red band, or if the element is damaged. Washing the element in a solution of Case Filter Element Cleaner A40910 and water is the preferred method, and the filter should be replaced after six washings. p. 283
What is the valve tappet clearance for the 188 diesel engine?
For the 188 diesel engine, the valve tappet clearance for both the intake and exhaust valves is .014 inch (0.356mm) for the exhaust and .012 inch (0.305mm) for the intake, measured when the engine is at operating temperature. p. 3
What is the correct torque for the cylinder head bolts on the 188 diesel engine?
The cylinder head bolts (Grade 8, 12 pt. hd.) on the 188 diesel engine should be torqued to 105 to 115 ft. lbs. (142 to 156 Nm). p. 17
What is the crankcase oil capacity for the 188 diesel engine?
The crankcase capacity for the 188 diesel engine is 6 U.S. Quarts (5.7 Litres) without the filter, and 7 U.S. Quarts (6.6 Litres) with a filter change. p. 3
What is the correct fan belt tension for the 350 crawler?
The fan belt should be adjusted to have 1/2 inch (12.7 mm) of deflection under 50 to 60 lbs. (22.7 to 27.2 kg) of tension on the belt tension gauge. p. 293
