Case 435, 445CT, 445 Common Problems This Manual Covers
Case 435 skid steer loses hydraulic power mid-job or won't build pressure, bucket dead
Check the troubleshooting procedures first. Confirm the hydraulic lock-out relay is energized, it should read 12 volts at the relay terminal per page 716. If voltage is present but the arm still won't lift, suspect the pump itself; displacement is 36cc (2.2 in³) per page 29, so a worn pump won't hit spec even with good electrical signal.
Manual Section: Primary Hydraulic Power SystemSteering feels loose, delayed, or jerks side to side instead of tracking smooth
Inspect the steering control handle linkage before condemning the valve. Clearance at the control handle should measure 25 to 40 mm (0.98 to 1.57 in) per page 575; anything outside that range lets the handle move without the valve spool responding. Adjust the linkage to spec, then re-check for erratic steering under load.
Manual Section: Steering Mechanical p. 575Engine cranks slow or won't fire, especially first start of the day
Test the starting circuit before pulling the starter. Battery terminal voltage under crank should hold at 12 volts per page 346; anything sagging lower under load points to a weak battery or corroded cable rather than a bad starter motor. Clean and torque terminal connections, retest voltage during actual crank, not just at rest.
Manual Section: Starting System p. 346Wiring harness in the cab area shows melted insulation, burnt smell, or scorch marks near the panel
Kill power at the battery disconnect immediately and do not re-energize the circuit until the harness is inspected. Check for a tripped 15 ampere circuit breaker per page 227; a circuit breaker that tripped repeatedly before the scorching means the short is still present downstream. Trace the harness run behind the instrument panel for chafed insulation against sharp metal edges, and replace any section with cracked or melted jacket rather than taping over it.
Manual Section: Electrical Power System p. 227Charging system warning stays lit or battery won't hold charge between shifts
Check alternator output at idle and at working RPM before swapping the unit. Torque for the pulley retaining nut is 60 to 73 Nm (45 to 54 lb ft) per page 133; a loose pulley nut causes belt slip and intermittent output that mimics a failing alternator. Re-torque to spec, verify belt tension, and retest charging voltage under load.
Manual Section: Alternator p. 133Engine runs hot and coolant level drops faster than normal use would explain
Check the coolant fill level against the rated system capacity of 17 L (18 US qt) per page 299 before chasing a sensor. If the system needs frequent top-off, pressure test the radiator cap and hoses for an external leak rather than assuming the coolant temperature sensor is at fault. Only move to sensor diagnostics once the system holds pressure and full capacity.
Manual Section: Engine Coolant System p. 299Frequently Asked Questions
How to re-enable loader motion and hydraulic flow after safety lock actuation on a 445CT?
On the 445CT, after safety lock actuation, loader motion and hydraulic flow to attachments are inhibited. To re-enable these functions, push the parking brake button. A flashing LED near this push button prompts the operator to release the brake to begin operation. p. 589
What torque specs are required for the 435 hydraulic pump mounting bolts?
For 435 machines, the bolts for the pump drive flange should be tightened to a torque of 39 - 43 Nm (29 - 32 lb ft) with Loctite 243 applied to the threads. The bolts for tandem pump mounting require a torque of 122 Nm (90 lb ft). p. 355
What are the error codes for 445 skid steer hydraulic pressure failure?
The manual mentions "diagnostic data (fault codes and troubleshooting)" and provides troubleshooting steps for hydraulic systems, including checks for charge pressure and efficiency. However, it does not list specific numerical or alphanumeric error codes for hydraulic pressure failure. p. 8
How to reset 435 parking brake button
To reset the 435 parking brake button and enable loader motion and hydraulic flow, push the parking brake button. A flashing LED near the button will prompt the operator to release the brake to begin operation. p. 589
