Common Issues & Solutions

• DPF/DEF Faults: Prompt regen, sensor replacement, and use of proper DEF fluid.

• High-Flow Hydraulic Leaks: Inspect couplers and O-rings; replace using dedicated kits.

• Undercarriage Wear: Regular clean-outs and tension checks reduce premature track and roller failure.

• Final Drive Leaks: Reseal or replace with full drive assemblies to avoid pump damage.

Serial Number Info

Machine identification is stamped near the rear track frame on the left side or inside the cab near the doorpost—important for ordering tier-specific parts.

Pro Tip: For high-temp or mulching jobs, include auxiliary cooler upgrades and Eco-mode after heavy cycles. Track loaders need frequent undercarriage cleanings to maintain alignment and prevent premature bearing or seal wear.
