Timberjack 1710 Parts Manual (F044112)

Hydraulic oil pouring out under a Timberjack 1710, loader dead, operator losing patience. You don’t guess in that situation. You grab the 1710 Parts Manual (F044112), match the blown hose in the book, get the exact hose ID, length, fitting type, and routing, and you’re back moving wood instead of crawling around in the mud for an hour.

Key Tasks Covered:

• Identify correct hydraulic hose part numbers by circuit and location.
• Match every fitting (BSP/JIC/ORFS, straight/90°/45°) to the right hose and port.
• Cross‑reference old superseded numbers to current service parts.
• Trace loader, bogie, and steering lines using exploded hydraulic diagrams.
• Order seals, pins, and bushings for loader and bunk without pulling wrong parts.
• Verify hardware sizes (bolts, washers, clamps) before tearing anything apart.

Common Questions:

Q: “I’ve got three hoses the same length in the rack. Which one belongs on the loader boom cylinder?”

A: Use the manual’s hydraulic section: match hose number, fitting angle, and port callouts on the cylinder and valve block.

Q: “Can I swap this metric fitting for what I’ve got on the truck?”

A: Only if the thread, seat type, and pressure rating match the part number spec in the book. If not, you’ll chase leaks all day.

Safety Note

Bleed hydraulic pressure and lockout before cracking any line, no shortcuts.
