All 370 pages of this John Deere 318D repair manual PDF (OEM #TM11399) zero in on one thing: getting your 318D, 319D, 320D, or 323D Skid Steer Loader back to factory spec. Inside: exploded views covering tracks, axles, hydrostatic motors, and loader components, plus unified inch and metric torque tables so you're never guessing at a fastener. You get detailed step-by-step procedures spanning the hydrostatic pump, park brake, transmission controls, hydraulic system components, cooling package, and full boom and cylinder assembly. Snug the fan drive motor inlet and outlet hydraulic hoses to 63 N·m (46.5 lb.-ft.) and the oil filter manifold cap screws to 18.5 N·m (164 lb.-in.); both numbers pulled straight from factory tables, not a forum post. Your machine is down. Grab the PDF on any device, jump to any section with pre-built bookmarks, and start wrenching.

John Deere 318D, 319D, 320D, 323D Common Problems This Manual Covers
John Deere 318D quick-tach linkage binds up and will not lock or release attachment p. 297
Inspect the actuator and pins for wear or debris. Clean the latch assembly thoroughly. Replace damaged components and tighten the boom-to-coupler pin cap screw to 320 N·m (236 lb-ft) as specified on page 297. Test the electric coupler for smooth operation.
Manual Section: LoaderLoader arms slowly drop when parked or hydraulic system feels weak under load p. 346
Check the hydraulic oil filter manifold for leaks or bypass conditions. Drain the reservoir and replace the restricted filter element. Torque the hydraulic oil filter manifold cap screw to 18.5 N·m (164 lb.-in.) using the values found on page 346. Bleed the cylinders.
Manual Section: Main Hydraulic SystemEngine overheats during normal heavy work cycles and fan drive motor leaks hydraulic fluid p. 275
Verify the cooling package is free of debris. Inspect the fan drive motor for external leaks. Replace the damaged hydraulic lines and tighten the inlet and outlet hoses to 63 N·m (46.5 lb.-ft.) as shown on page 275. Refill the system.
Manual Section: Main Hydraulic SystemMachine feels sluggish while turning and drive axle exhibits excessive rolling drag p. 64
Remove the wheel and inspect the axle housing support. Verify the axle bearing rolling drag torque is between 40 and 120 lb-in as detailed on page 64. Fill the axle housing with exactly 8 oz of oil. Reinstall the wheel retainer nuts.
Manual Section: Axles and Suspension SystemsFrequently Asked Questions
Why do the loader arms on my 318D slowly drift down when parked?
Check the hydraulic oil filter manifold for leaks or bypass conditions. Replace a restricted filter element and torque the manifold cap screw to 18.5 N·m (164 lb.-in.) per the factory spec on page 346. Then bleed the lift cylinders to restore full pressure.
My 318D quick-tach will not lock or release the attachment — what should I check?
Inspect the actuator and latch pins for wear or debris and clean the assembly thoroughly. Tighten the boom-to-coupler pin cap screw to 320 N·m (236 lb-ft) as specified on page 297, then test the electric coupler for smooth engagement.
The fan drive motor on my 320D is leaking hydraulic fluid — what is the correct hose torque?
Replace any damaged hoses and tighten the fan drive motor inlet and outlet hoses to 63 N·m (46.5 lb.-ft.) and the case drain hose to 37 N·m (27 lb.-ft.), both from the factory table on page 275. Refill and check the cooling package for debris.
Where do I find torque specs for fasteners on my 318D or 323D?
Pages 19 and 20 contain the unified inch and metric bolt torque tables covering all standard fastener grades used on the machine. Look up the fastener size and grade before reassembly to avoid over- or under-torquing.
My 318D drive axle has excessive rolling drag — what is the correct axle bearing spec?
Remove the wheel and verify axle bearing rolling drag torque is between 40 and 120 lb-in as detailed on page 64. Fill the axle housing with exactly 8 oz of oil before reinstalling the wheel retainer nuts.
