Case 1270, 1370, 1570 Common Problems This Manual Covers
Case 1370 head gasket keeps leaking after replacement, cylinder head shows visible cracking
Pull the head and check for hairline cracks between valve seats before reusing it. Torque the cylinder head cap screws in three stages per page 10: 70, 140, then 210 ft-lbs, following the correct sequence. Skipping the staged torque is the usual reason a fresh gasket blows again within weeks.
Manual Section: Engine p. 10Wheel u-joints cracking or snapping under load during field work
Inspect both u-joints for surface cracking and side play any time you pull a wheel end for other service. Grease at every scheduled interval and replace in pairs, not one at a time, since the surviving joint is already fatigued from carrying the extra load. Do not run the tractor if you feel any looseness when rocking the wheel by hand.
Manual Section: Axle, Front p. 3PTO shaft seal weeping oil around the output shaft housing
Remove the shaft and check the seal lip for hardening or a scored wear groove on the shaft surface. Lubricate the new seal lip, set it over the output shaft with the lip facing inward, and drive it into the bore until the outer face sits flush with the transmission case per page 66. A seal seated crooked or proud of the case is the most common cause of repeat leaks.
Manual Section: Power Take-Off p. 66Plastic fuel line pulsating between the transfer pump and filters, engine surging
Check the line for kinks, chafe points, or a soft spot where it's collapsing under vacuum. Verify fuel pressure at the injection pump inlet fitting; it should read 20-30 psi per page 20. If pressure fluctuates instead of holding steady, replace the plastic section with new line and reseat the clamps before condemning the pump.
Manual Section: Fuel System p. 20Power shift whines and grinds between gear changes
Run the power shift clutch pressure test before tearing into the gearset; low clutch operating or lubrication pressure points to internal leakage in the clutch circuit rather than the gears themselves. Check the test results on page 35 against spec and look for leakage past the clutch piston seals before condemning the ring gear or shifter forks.
Manual Section: Power Shift Clutch p. 35Green-tinted oil draining from the plug, suspect coolant contamination
Drain a sample into a clear container and let it settle; a green tint usually means coolant is mixing in through a failed heat exchanger or a cracked case passage. Check the cooling system on page 26, starting with the thermostat and water pump seals, before refilling. Do not run the engine again until you confirm the source, since contaminated oil will wipe the main bearings fast.
Manual Section: Cooling System p. 26Frequently Asked Questions
How do I adjust the park lock on Case 1370/1570 tractors?
To adjust the park lock, place the Range Shift lever and park lock quadrant in neutral (Park Off) position. Adjust the park lock rod so the center-to-center distance of rod holes is 20-5/8 inches. Then, move the control lever to 'Park On' position and ensure the shaft lever has moved 18½ degrees up from the 'Park Off' position. p. 56
What are the replacement specifications for the engine head gasket?
Engine head gaskets are designed with an integral fire ring for each cylinder, compressing to seal the sleeve to the cylinder head. Sleeves must protrude no more than 0.006 inch above the block, and not be lower than flush with the block surface. Head gaskets also feature two smaller guide bolt holes for alignment. p. 9
What is the engine oil capacity for Case 1270/1370 and 1570 tractors?
The engine crankcase oil capacity, including the filter, is 22 quarts for the 1270 and 1370 models. For the 1570 model, the crankcase oil capacity with the filter is 26 quarts. p. 3
What are the torque specifications for the cylinder head cap screws?
The cylinder head cap screws should be tightened in three stages: first to 70 ft.-lbs., then to 140 ft.-lbs., and finally to 210 ft.-lbs. This procedure should follow the sequence illustrated in Fig. 20. p. 10
