Part of the Case Repair Manuals.
Every single one of the 96 pages in this Case/international 585 Shop Manual PDF zeroes in on getting your 385, 485, 685, and 885 series tractor back to work. You get detailed exploded views for the entire front-wheel drive system, a full section of step-by-step transmission rebuild procedures, and dedicated troubleshooting charts for the hydraulic lift. Open the file to find clear engine teardown instructions covering everything from main bearings to injection timing. Verify your Lucas starter armature end play sits perfectly between 0.005 and 0.025 inches, then lock down the filter center bolt to 12-16 ft.-lbs. A broken tractor costs you daylight. Grab this bookmarked download, pull it up on your tablet in the barn, and fix the problem right the first time.

Case 385 / 485 / 585 / 685 / 885 Common Problems This Manual Covers
Case IH 385/485/585/685/885 engine cranks slowly or won't turn over at all, no start
Check total battery voltage and inspect terminals for corrosion or loose cable connections first. Clean and tighten all connections, then load-test the battery. If cranking is still weak, pull the starter and check armature end play; Lucas units run 0.005-0.025 inch (0.13-0.63 mm) on page 52, Bosch units run 0.004-0.016 inch (0.1-0.4 mm) on page 53. Replace the starter if end play is out of spec.
Manual Section: Batteries p. 52Overheating during light field work even though coolant level looks fine
Pull the radiator cap and verify it holds 9-12 psi (62-82 kPa) as specified on page 45; a weak cap drops the boiling point and triggers early overheating under light load. Inspect the radiator core for mud or chaff blocking airflow and check the water pump for a failing seal or worn impeller. Confirm impeller installation dimension is within 0.012-0.020 in. (0.305-0.508 mm) before reassembly.
Manual Section: Radiator p. 45Coolant temperature spikes but gauge reads normal at idle
Test the thermostat in a pot of heated water; it should start opening at 180°F (84°C) and be fully open by 207°F (97°C) per the specs on page 45. If it sticks closed past that range, replace it rather than removing it outright. While it's apart, check the water pump retaining bolts are torqued to 15 ft.-lbs. (20 N·m) so the housing seals properly and doesn't weep coolant.
Manual Section: Thermostat p. 45Hydraulic lift loses pressure intermittently or moves implements erratically
Check the troubleshooting procedures for no-lift, slow-lift, and high-pressure symptoms before tearing into the pump. Pull and inspect the hydraulic filter element; it should be renewed after the first 20 hours, again at 200 hours, then every 800 hours per page 23. When reinstalling, torque the filter center bolt to 12-16 ft.-lbs. (16-21 N·m) on page 25 so it doesn't leak or loosen under vibration.
Manual Section: Hydraulic Lift System - Trouble ShootingFluid level looks correct but system still runs low on hydraulic oil
Verify total transmission, differential and hydraulic fluid capacity against the 36 U.S. qts. spec on page 6, since a shared sump means a leak anywhere in the drivetrain shows up as low hydraulic fluid. Check hose fittings, the lift housing, and control valve seals for weeping oil. Top off only after confirming there's no active leak, otherwise you'll be back under the tractor within a week.
Manual Section: Transmission, Differential and Hydraulics, Capacity p. 6No drive or clutch slips when shifting between forward and reverse
Check the Forward-Reverse troubleshooting index for no-drive and slipping-clutch causes before pulling the transmission apart. Verify clutch pedal height and linkage adjustment is correct, since a misadjusted pedal prevents full clutch engagement. Inspect the clutch discs for glazing or excessive wear and replace them if slippage continues under load after adjustment.
Manual Section: Transmission, Forward-Reverse - Trouble ShootingFrequently Asked Questions
What are the torque specifications for the engine head bolts on Case IH 885?
For all models, including the Case IH 885, the cylinder head retaining cap screws should be tightened in three steps: first to 30 ft.-lbs. (41 N·m), then to 60 ft.-lbs. (81 N·m), and finally to 110 ft.-lbs. (149 N·m). This procedure is outlined in paragraph 36. p. 31
What are the torque specifications for the axle mounting bolts on Case 585?
For the final drive assembly on all models, including Case 585, the axle mounting cap screws (7-Fig. 137) should be tightened to a torque of 220-250 ft.-lbs. (298-339 N·m). For the front axle main member, cap screws (16) and (22) should be tightened to 80-90 ft.-lbs. (110-124 N·m). p. 77
How to swap torque specs for Case 585 engine head
For all models, including the Case 585, the cylinder head retaining cap screws should be tightened in three steps: first to 30 ft.-lbs. (41 N·m), then to 60 ft.-lbs. (81 N·m), and finally to 110 ft.-lbs. (149 N·m). This procedure is outlined in paragraph 36. p. 31
What is the crankcase oil capacity (with filter) for Case International 385/485 and 585/685/885 diesel models?
The crankcase oil capacity with filter for 385 and 485 Diesel models is 8 U.S. qts. (7.5 L). For 585, 685, and 885 Diesel models, it is 10 U.S. qts. (9.5 L). p. 5
What is the valve tappet gap (hot) for intake and exhaust on Case International 385/485/585/685/885 diesel models?
For all Case International diesel models (385, 485, 585, 685, 885), the valve tappet gap (hot) for both intake and exhaust is 0.012 in. (0.304 mm). This is a critical tune-up specification. p. 5
