Mechanical Workshop Guide for John Deere 312GR & 314G Skid Steers
The John Deere 312GR and 314G are the agile entry-level workhorses of the G-Series lineup, specifically designed for narrow-gate access, interior demolition, and small-scale landscaping. While compact, these machines are built with the same heavy-duty structural integrity as their larger counterparts. Over hundreds of hours of operation, the physical hardware—from the radial lift arm bushings to the final drive chains—will require precise mechanical servicing. The John Deere 312GR and 314G Repair Service Technical Manual (TM13859X19) is the definitive shop-floor resource for executing these heavy structural restorations.
Available for immediate digital download exclusively through Manualsmarket.com, this factory reference provides mechanics with the exact torque tolerances, assembly sequences, and structural wear limits required to keep these radial-lift loaders in peak mechanical condition.

Mechanical Hardware & System Overhauls
This repair guide bypasses software logic to focus entirely on the "nuts and bolts" of the 312GR and 314G. It is organized by machine section, allowing your service team to jump straight to the components requiring heavy wrenching.
- Drivetrain & Axle Group: Detailed instructions for opening the internal chain cases, measuring drive chain deflection on the small-frame G-series, and the physical process for pressing new wheel bearings and axle seals.
- Radial Lift Linkage: Safe techniques for extracting seized loader arm pins, verifying bushing wear limits on the 312GR and 314G lift geometry, and overhauling the Quik-Tatch coupler assembly.
- Hydraulic Component R&R: Step-by-step mechanical removal of the hydrostatic tandem pumps, unbolting auxiliary gear pumps, and the complete tear-down and resealing of the lift and tilt cylinders.
- Powerplant & Chassis: Guidelines for safely tilting the operator enclosure (ROPS), uncoupling the cooling package, and the physical extraction of the engine block from the frame for major servicing.
Who Benefits from this Technical Publication?
- Small Business Contractors: Perform your own axle seal and chain case maintenance in your garage to avoid expensive dealership wait times.
- Landscape Property Managers: Ensure the longevity of your 312GR by using the exact factory torque specs when replacing worn bucket pins or linkage bushings.
- Independent Diesel Repair Shops: Access the most accurate OEM assembly sequences to provide professional-grade service for G-series small-frame owners.
- Used Equipment Refurbishers: Utilize factory-verified wear charts to restore high-hour 314G loaders to job-ready, reliable condition for resale.
The Rule of Maintenance: Repair vs. Diagnostic Data
To maximize efficiency in your shop, it is vital to understand the scope of this file. The TM13859X19 is strictly a Service Repair Technical Manual. It is formulated specifically for the physical removal, dismantling, and reassembly of mechanical parts. This manual explicitly does not contain Schematic Wiring Diagrams or Diagnostic Trouble Codes (DTCs). If your loader is suffering from a sensor failure, an electrical short, or a flashing monitor code, you must procure the separate Diagnostic, Operation, and Test manual designed for the 312GR and 314G.
Shop Floor FAQ
Does this manual cover the internal engine rebuild?
No. This document covers the mechanical removal of the engine from the loader frame and the disassembly of external accessories. For internal engine work like pistons and crankshafts, a separate engine-specific manual is required.
Are the electrical wiring maps included in this file?
No. Electrical schematics and circuit testing are exclusively published in the companion diagnostic manual. This guide focuses on physical wrenching and hardware restoration.
Does it include the steps to adjust the drive chain tension?
Absolutely. The chain case section provides the exact factory deflection measurements and the physical steps required to adjust the tensioning system properly for this small-frame series.
Can I view these teardown instructions on my phone?
Yes. The digital PDF format is fully compatible with smartphones, tablets, and shop computers, allowing you to access the factory blueprints right at the machine.
