A wheel disc that works loose mid-shift usually starts with somebody torquing from memory. The Ford 345C, 445C, 545C operator manual PDF (OEM ID 42034530) is the factory book written to prevent that: 122 pages covering controls, operation, lubrication and specifications for all three tractor loaders. Loader work gets its own chapter, from control lever functions and the bucket level indicator through hydro-mechanical self-levelling, the transmission dump switch and correct bucket installation. Lubrication and maintenance fills roughly a quarter of the book, with service charts, dry air cleaner procedures and a full specifications chapter behind them. Pull rear disc-to-hub nuts to 250 lbf.ft (475 Nm) and hold your idle between 600 and 850 rpm. Guess those numbers and you buy a sheared stud. Bookmarks and a live text layer put you two clicks from any spec.

Ford 345C, 445C, 545C Common Problems This Manual Covers
Ford 345C tractor starts fine but intermittent transmission shift trouble when changing direction
Inspect the transmission disconnect switch and linkage. Start the engine and verify idle speed is between 600-850 rpm as shown on page 28. Check the torque converter oil level on a level surface. Adjust the directional control linkage if shifting remains erratic.
Manual Section: Controls, Instrument and Operation p. 28Loss of hydraulic power and weak loader response during bucket lift or heavy material cycles
Check fluid levels before operating the loader control lever shown on page 41. Verify the engine is running at the 600-850 rpm operating idle. Inspect the suction screen and main filter for debris. Fill the reservoir with approved hydraulic fluid until the level reaches the full mark.
Manual Section: Loader Controls and Operation p. 41Clunking noise from the rear axle when shuttling forward and reverse under heavy tip load
Torque the rear disc to hub nuts to exactly 250 lbf.ft (475 Nm) as specified on page 35. Inspect the rim for elongated holes. Tighten the rear disc to rim nuts to 129 lbf.ft (176 Nm). Check tire pressure before returning the machine to service.
Manual Section: Controls, Instrument and Operation p. 35Erratic power steering response and front wheel wobble while carrying a full bucket over rough terrain
Inspect the steering cylinder seals for leaks. Torque the two wheel drive front disc to hub nuts to 130 lbf.ft. (176 Nm) according to the maintenance instructions on page 75. Verify hydraulic fluid level is full and grease the steering linkage and tie rod ends.
Manual Section: Lubrication and Maintenance p. 75Frequently Asked Questions
What are the torque specifications for the rear wheel disc to hub nuts on a Ford 345C, 445C, 545C?
The torque specification for the rear wheel disc to hub nuts is 250 lbf.ft (475 Nm). This should be checked after driving the tractor for 200 yards (200 m), after 1 hour and 8 hours of operation, and thereafter at the 50-hour service intervals. p. 35
What is the correct intake and exhaust valve clearance for the Ford 345C, 445C, 545C engine?
The intake valve clearance is 0.014 – 0.016 in. (0.36 – 0.41 mm), and the exhaust valve clearance is 0.017 – 0.019 in. (0.43 – 0.48 mm). These adjustments should be performed with the engine cold. p. 83
How often should the engine oil and filter be changed?
The engine oil and filter should be changed every 300 hours under normal conditions. However, if operating in temperatures below 10°F (-12°C), the oil should be changed every 150 hours. p. 79
What is the correct fan and alternator belt deflection?
The fan and alternator belt should be adjusted to have a deflection of 0.50 – 0.75 in. (13 – 19 mm) when hand pressure is applied midway between the alternator and crankshaft pulley. p. 80
What is the procedure for bleeding the fuel system?
To bleed the fuel system, slacken the bleed screw on top of the fuel filter/sediment separator until fuel free of air bubbles flows out, then tighten it. Then, loosen the bleed screw on the injection pump and crank the engine until fuel free of air bubbles flows out, then tighten the screw. p. 86
Is this Ford 345C manual a download or a disc?
This is a 122-page searchable PDF ready for immediate download. Works on any device, so pull it up on your phone while you're under the hood. No shipping, no waiting.
Can I print just the pages I need from this Ford 345C manual?
