Gehl built the CTL60 and TL130 on shared systems, and this OEM manual (#908310) documents them at factory depth across 755 pages. Hydraulic schematics map the HST pump, gear pump, control valve, pilot valve, and self-level valve circuits, backed by wiring diagrams for the full electrical system. The machine configuration section walks through drive, travel, frame, controls, and attachments, while 15 pages of troubleshooting charts work through travel faults, lift arm issues, and bucket problems in sequence. Engine coverage runs deep for both the 4TNE94/98/106 and the 3TNV/4TNV series, with complete rebuild procedures. Need the real numbers? Track roller A bolts torque to 241 N·m; connecting rod bolts run 53.9 to 58.8 N·m on the 4TNV94L/98. Bookmarked by section and keyword-searchable, so you can pull a spec on any device and get back to the machine.

Gehl CTL60, TL130 Common Problems This Manual Covers
Engine fires, then quits about five seconds later while the top-panel warning light stays on. p. 605
Start with the fuel system: replace the filter element (page 586) and drain any water from the separator (page 578). Confirm the safety interlock circuit isn't forcing an early shutdown. Torque the new fuel filter to 20 to 24 N•m per page 586.
Manual Section: Vi . EngineBoom and bucket lose all hydraulic power while the tracks keep driving normally. p. 331
Test the pilot valve pressure using the procedures on page 331; a healthy reading sits between 0 and 3.0 MPa. Inspect the control valve main relief valve, and check that the tie rod nut is torqued securely.
Manual Section: Lift Arms: Lift arm cylinders fail to moveRough running and a misfiring cylinder, with rocker arms that keep working loose during operation. p. 630
Measure the valve clearance and set it to the standard 0.15 to 0.25 mm spec on page 592. Inspect the rocker arm shaft hole diameter on page 630; if it runs past the 18.500 to 18.520 mm range, replace the worn parts.
Manual Section: Vi . EngineTravel feels sluggish and drive power fades under heavy load. p. 329
Confirm the hydraulic oil level first, following page 329. If it reads normal, verify the HST pump relief valve setting; on the CTL60 it must measure 34.5 MPa. Top off with fresh hydraulic oil if the reservoir is low.
Manual Section: Overall Machine: All systems working, but with insufficient powerFrequently Asked Questions
What is the torque spec for the Gehl CTL60/TL130 track roller bolts?
Tighten the track roller A installation bolts to 241 N·m and the track roller B bolts to 156 N·m. Apply thread-locking compound as you go.
What is the torque spec for the Gehl CTL60/TL130 engine head bolts?
4TNV94L/98 cylinder head bolts go in two stages: first 49.0 to 58.8 N·m (5.0 to 6.0 kgf·m), then 103.1 to 112.9 N·m (10.5 to 11.5 kgf·m). On 4TNV106(T) engines, the first stage is 88.3 to 98.1 N·m (9.0 to 10.0 kgf·m) and the second is 188.0 to 197.8 N·m (19.0 to 20.0 kgf·m).
What are the replacement specifications for Hydraulic pump components?
Replace the HST pump cylinder block if flatness exceeds 0.002 mm TIR or the maximum bore diameter tops 14.30 mm. Swap the valve plate when its thickness drops below 4.97 mm or flatness passes 0.0038 mm TIR. On the gear pump, replace the assembly if housing contact marks exceed 0.1 mm, if gear shaft or side surfaces are rough, or if oil seal contact points are worn deeper than 0.1 mm. Replace any seal that is damaged or worn.
What are the replacement specifications for Hydraulic control valve components?
Replace the housing or section body if you find scratches, rust, or corrosion on sliding parts, seal pockets, or port seals. Swap the spool if it shows scratch marks or won't move smoothly. A load check valve that seals imperfectly needs replacing, as do springs that are corroded or deformed. Solenoid coils get replaced when burned, short-circuited, or carrying a broken wire.
