Case IH ST450/ST470 (Tiger III) Common Problems This Manual Covers
Powershift transmission overheats after extended operation or hills
Check transmission oil level first — normal fill is 14.25 gallons (53.9 liters) including filters per page 20. Inspect the cooler oil lines for kinks or blockage. Verify the engine coolant is not also running hot, since the transmission cooler shares the engine cooling circuit. Reduce vehicle load or speed until oil temperature returns to normal range. See the transmission overheating checklist on page 98.
Manual Section: Troubleshooting p. 98Engine hard to start or cranks without firing in cold conditions
Confirm the fuel shut-off valve is fully open and the tank has fuel — capacity is 385 gallons (1457.22 liters). Inspect fuel lines and connections for air leaks, which are a primary cause of hard starting. Check that air intake is unrestricted and filters are not clogged. Review the hard-starting checklist on page 101, which covers fuel quality, worn pump, and water-in-fuel conditions.
Manual Section: Troubleshooting p. 101Low engine oil pressure warning during operation, gauge reading below normal
Immediately reduce load and check crankcase oil level before continuing operation. Inspect for visible external oil leaks around seals and drain plugs. Verify you are using the correct oil grade for ambient conditions per the service schedule on page 52. A dirty oil filter or restricted suction line will also drop oil pressure — the full diagnostic checklist including cooler and cooling system checks is on page 100.
Manual Section: Troubleshooting p. 100Engine lacks power or bogs down under load during field operations
Inspect the air filter and intake path for restriction — dirty filters are the first item to eliminate. Check fuel quality and look for air leaks in suction lines, which cause lean running and power loss. Extended idling degrades performance over time, so follow the idle-period guidelines in Operating Information starting page 27. If power loss persists after filter and fuel checks, review the full low-power checklist on page 100.
Manual Section: Troubleshooting p. 100Frequently Asked Questions
How do you fix St 450 & St 470 Tiger Iii engine coolant temperature warning light on during heavy field work?
Check the grill screen first — a clogged screen is the most common cause. Clean dirt and debris from the radiator core and inspect all coolant hoses for damage or kinking. Verify coolant level is adequate and look for air bubbles indicating air in the system. Reduce load and idle the engine to allow cooling before resuming operation. Full diagnostic checklist is on page 99. p. 99
How do you fix hydraulic steering feels sluggish or implements respond slowly under load?
Verify the hydraulic reservoir level is at the correct mark — capacity is 48 gals. (181.7 liters) when full. Inspect all visible hydraulic lines for kinks, abrasion, or leaks. Check that the system main relief valve is set to 2450 psi (169 bars) per the specs on page 19. If level and lines are good, check the pump output — rated at 38 gpm (143.8 lpm) — and look for signs of intermittent pressure drop under load.
