Transfer Cases & PTOs

Service Scope

We provide full-service transfer case and PTO repair solutions designed to restore reliable power distribution and auxiliary operation for Jacksonville fleets.

This includes everything from preventative maintenance and diagnostics to complete rebuilds and remanufacturing of complex drivetrain components. Our work focuses on correcting engagement issues, eliminating noise and vibration, and ensuring consistent torque delivery under load.

• Transfer Case Rebuilds: Full restoration of manual and electronic-shift units for commercial and off-road use.

• PTO System Repair: Expert diagnostics and repair for auxiliary power units (Muncie, Chelsea, Eaton).

• Precision Gear Setup: Accurate gear-lash calibration between the PTO and transmission to prevent premature wear.

• Chain & Bearing Replacement: Restoration of internal tolerances to eliminate "slop" and drivetrain noise.

• Seal & Gasket Restoration: Comprehensive sealing service to prevent fluid loss and environmental contamination.

• Engagement Correction: Solving shifting issues in 4WD and auxiliary systems for dependable activation.

Common Symptoms

Early detection of unusual noises or shifting resistance is critical to avoiding catastrophic housing failures and unplanned equipment downtime.

• Difficulty Engaging/Disengaging: 4WD or PTO systems that pop out of gear or refuse to activate under load.

• Grinding or Rattle: Common signs of a stretched transfer case chain or failing planetary gear set.

• Auxiliary Power Loss: Inconsistent performance in hydraulic pumps, blowers, or mechanical attachments.

• Fluid Leaks: Puddles of lubricant or a burnt odor indicating seal failure and high-heat friction.

• Vibration During Acceleration: Often linked to worn output shaft bearings or internal misalignment.

Our Process

Each unit undergoes a forensic technical protocol to identify the root cause of failure and ensure a rebuild that is hardened for long-term service.

• Forensic Teardown: Complete disassembly and industrial cleaning to inspect for heat checking and fractures.

• Failure Analysis: Evaluation of gears, chains, and splines to determine why the original component failed.

• Precision Reassembly: Building to OEM-equivalent or upgraded specs with verified internal clearances.

• Housing Restoration: Inspection and repair of mounting surfaces and seal bores for a perfect fit.

• Functional Load Testing: Validation of smooth torque transfer and engagement accuracy before release.

Frequently Asked Questions (FAQ’s)

Commonly asked questions regarding the maintenance, repair, and troubleshooting of transfer cases and Power Take-Off systems.

• Where can I get a PTO repaired in Jacksonville?

  • Old Glory Fab is a specialized facility for vocational PTO and transfer case repair serving the entire First Coast region.

• What causes a transfer case to make a clicking noise?

  • This is usually a sign of a stretched chain skipping over gear teeth, which can eventually wear through the housing.

• Why won't my PTO engage?

  • Issues often stem from air leaks in shift cylinders, electrical solenoid failures, or worn slider gears.

• Can you rebuild Muncie and Chelsea PTOs?

  • Yes, we specialize in the setup and gear-lash calibration of all major vocational brands.

• How much does a transfer case rebuild cost?

  • Labor typically starts at 750 plus the cost of the master overhaul kit.

• Is it normal for a PTO to whine?

  • Excessive whining usually means the PTO was installed with improper backlash, which can damage your transmission.

• Do you work on electronic shift-on-the-fly systems?

  • Yes, we diagnose and repair both manual and electronic shift motors and encoders.

• How often should I change transfer case fluid?

  • We recommend a fluid inspection every 15,000 to 30,000 miles for vocational equipment.

• Can I ship my unit to your shop?

  • Yes, we accept bench service units shipped from across the country for forensic rebuilds.

• Do you repair 4WD systems for construction equipment?

  • Absolutely, we service drop boxes and transfer cases for a wide variety of industrial and earthmoving machinery.
