Safely Lifting the Cab on a Bobcat T190 for Maintenance Access

[MikePhua]

The T190 and Bobcat’s Compact Track Loader Evolution
The Bobcat T190 was introduced in the early 2000s as part of Bobcat’s compact track loader lineup, offering enhanced traction, low ground pressure, and versatile hydraulic performance. With a rated operating capacity of 1,900 lbs and an operating weight of approximately 7,600 lbs, the T190 quickly became a favorite among contractors, landscapers, and utility crews. Its vertical lift path, 66-inch width, and compatibility with dozens of attachments made it ideal for confined job sites and precision grading.
Bobcat, founded in North Dakota in the 1950s, pioneered the skid steer concept and later expanded into track loaders to meet demand for better flotation and stability. The T190’s cab-over-engine design allows for a compact footprint, but accessing internal components—especially hydraulic valves, wiring harnesses, and control linkages—requires lifting the cab.
Why Cab Access Is Critical for Service
Routine maintenance and troubleshooting on the T190 often involve components located beneath the operator cab. These include:

• Hydraulic control valve block
  
• Pilot control lines and fittings
  
• Wiring harness junctions and relays
  
• Drive motor hoses and couplers
  
• Fuel lines and return filters
  

Symptoms that may require cab access:

• Hydraulic leaks or erratic control response
  
• Electrical faults or intermittent power loss
  
• Stiff joystick movement or linkage wear
  
• Fuel delivery issues or vapor lock
  

A technician in Alberta once diagnosed a joystick lag issue on a T190. After lifting the cab, he discovered a kinked pilot line rubbing against the frame. Re-routing the hose restored smooth control and prevented future wear.
Preparation and Safety Before Lifting the Cab
Before lifting the cab, several safety steps must be followed:

• Park the machine on level ground and lower all attachments
  
• Shut off the engine and remove the key
  
• Disconnect the battery to prevent electrical shorts
  
• Release hydraulic pressure by cycling controls
  
• Wear gloves and eye protection during the procedure
  

Tools required:

• Ratchet and socket set (typically 9/16" or 14mm)
  
• Pry bar or cab assist handle
  
• Safety prop rod or locking pin
  
• Optional: second person for assistance and spotting
  

A restorer in Chile added a custom prop rod with a locking collar to his T190. The modification ensured the cab remained secure during extended diagnostics and valve replacement.
Step-by-Step Cab Lifting Procedure
The T190 cab is hinged at the rear and secured at the front with bolts or latches. To lift:

• Remove the front cab bolts located near the footwell
  
• Locate the cab pivot points and ensure they are free of debris
  
• Use the assist handle or pry bar to begin lifting from the front
  
• Raise the cab slowly until it reaches its full open position
  
• Engage the safety prop rod or install a locking pin to secure the cab
  

Important notes:

• Do not rely on hydraulic cylinders or loader arms to support the cab
  
• Avoid lifting with attachments connected or raised
  
• Inspect hinge bushings and pivot pins for wear during the process
  

A fleet manager in Texas added cab lifting to his 500-hour service checklist. By inspecting hoses and wiring during each lift, he reduced hydraulic failures and electrical shorts across his loader fleet.
Accessing Components and Performing Repairs
Once the cab is lifted, technicians gain access to:

• Hydraulic valve block and solenoids
  
• Pilot control manifold and fittings
  
• Electrical junction box and relays
  
• Drive motor hoses and quick couplers
  
• Fuel tank fittings and return lines
  

Common repairs performed under the cab:

• Replacing leaking O-rings or cracked fittings
  
• Cleaning electrical contacts and resealing junctions
  
• Adjusting control linkage tension and alignment
  
• Inspecting hose routing and adding abrasion sleeves
  

A technician in Ontario used a borescope to inspect a hidden hydraulic leak beneath the cab. The tool revealed a pinhole in a return hose, which was replaced before it caused a pressure drop.
Lowering the Cab and Final Checks
To close the cab:

• Remove the safety prop rod or locking pin
  
• Lower the cab slowly and ensure alignment with mounting points
  
• Reinstall front bolts and torque to spec
  
• Reconnect the battery and start the machine
  
• Cycle controls and check for leaks or faults
  

Post-lift checklist:

• Verify joystick response and control smoothness
  
• Inspect for pinched wires or hoses
  
• Confirm all fasteners are secure
  
• Document repairs and update service log
  

A contractor in Florida added a QR code to his T190’s cab interior linking to a digital service manual. This allowed technicians to access diagrams and torque specs during cab lifts without printed documents.
Conclusion and Recommendations
Lifting the cab on a Bobcat T190 is a necessary procedure for accessing critical systems. When done safely and methodically, it enables thorough diagnostics, efficient repairs, and long-term reliability.
Recommendations include:

• Follow safety protocols and use proper tools
  
• Inspect pivot points and prop mechanisms regularly
  
• Perform preventive checks during each cab lift
  
• Document findings and update maintenance records
  
• Train technicians in cab lifting procedures and hazard awareness
  

With careful execution, cab access becomes a gateway to deeper machine understanding—ensuring the T190 continues to perform with the precision and durability that define Bobcat’s compact loader legacy.
