Part of the John Deere Repair Manuals.
This 236-page John Deere 313, 315, CT315 Technical Manual (TM10608) puts every wrench turn on the Skid Steer Loader and Compact Track Loader chassis in front of you, from the hydrostatic drive train down to the track roller bolts. You get full disassemble-and-assemble procedures for the hydrostatic pump and motor, control valve teardown steps, boom cylinder R&I, and a dedicated torque values section covering everything from engine bolts to track roller hardware. Set hydraulic hose replacement on a strict once-a-year interval, and confirm every fastener against Group 0003 before you close the machine back up. Your hydrostatic system won't forgive a guessed torque spec, and neither will your customer when the machine comes back. Bookmarked by group number, so you jump straight from Section 03 hydraulics to Section 31 loader work without flipping through 200 pages of General Information first.

John Deere 313, 315 & CT315 Common Problems This Manual Covers
John Deere 315 skid steer engine misses, fires irregularly, and dies under heavy load.
Replace the fuel filters and inspect the hydrostatic pump assembly. Torque the mounting bracket cap screws to 76 N-m (56 lb-ft) as shown on page 103. Inspect the hydraulic system for loose fittings that create pulsing during cranking or operation.
Manual Section: Section 03 p. 103Noticeable hydraulic system performance decrease and visible fluid leaks near the main pump.
Replace hydraulic hoses at least once per year as specified on page 12. Inspect the hydraulic pump gear shaft for wear, ensuring the diameter measures exactly 19.00 mm on page 176. Check control valve seals for damage and replace if necessary.
Manual Section: Section 31 p. 176Compact track loader gains little tractive effort and slips in muddy conditions.
Measure the rubber track lug height and replace the tracks if they wear below the 5.0 mm minimum on page 37. Inspect the track rollers for leaks and verify they are filled to the 225 mL gear oil capacity on page 42.
Manual Section: Section 01 p. 37Complete loss of steering or loader control during normal operation and bucket functions.
Inspect the hydrostatic motor and park brake assembly for broken actuator wires or loose connections. Torque the motor end cover cap screws to 43 N·m (32 lb-ft) as detailed on page 101. Verify the flushing valve plug is tightened to 30 N·m (22 lb-ft) on page 32.
