Safety Information
Most accidents that involve product operation, maintenance, and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. The operator should also have the necessary training, skills, and tools to perform these functions properly.
Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons
Illustration 2 | g06350515 |
Improper operation, lubrication, maintenance, or repair of this product can be dangerous and could result in injury or death.

- Stand a safe distance back when lifting load.
General Description
Illustration 9 | g06350515 |
Personal injury or death can result from improper lifting or blocking.
When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure that the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component.
Approximate weights of the components are shown.
Illustration 10 | g06350515 |
To avoid injury, do not stand on or between implement and machine while operating lift control.
The Pin Puller Assembly is designed to facilitate removal and installation of the 797F Center Steering Pin. There are two different Center Steering Pin that can be removed,
The Pin Puller Assembly comes with a specialized double acting 498-6578 Hydraulic Cylinder to facilitate safe, controlled removal and installation of the Center Steering Pin. An integrated guard on the pin puller retains the Center Steering Pin within the pin puller for the duration of the removal/install.
The Component Handler is used to raise and lower the Pin Puller Assembly into position beneath the 797F Center Steering Pin.
The Support Lift Assembly is used to mount the Pin Puller Assembly to the Component Handler. The Support Lift Assembly is also used to mount the Arm Support Assembly to the Component Handler.
The Arm Support Assembly is used to position and retain the Center Steering Arm during Center Steering Pin removal/installation. A Hydraulic Jack Assembly is used to make minor lifting adjustment to the Center Steering Arm to aid in pin bore alignment.

Maintenance
Be sure to read all other manuals that come with the other tools. Heed all warnings and safety practices that go along with the maintenance, cleaning, storage, and disposal.
Illustration 48 | g06350515 |
Pressure can be trapped in hydraulic circuits after the power supply has stopped. Personal injury or death can result from failure to release hydraulic pressure in a hydraulic system before hoses are disconnected or removed. Release all the pressure from the hydraulic system before any lines are disconnect.
Illustration 49 | g06350515 |
Check hydraulic oil lines, tubes, and hoses carefully. DO NOT use your bare hand to check for potential leaks. Always use a board or cardboard when checking for a leak. Escaping hydraulic fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury or death. If fluid is injected into your skin, the injury must be treated immediately by a doctor familiar with this type of injury.
Illustration 50 | g06350515 |
Contact with hot oil or hot components can result in severe burns. To avoid personal injury, DO NOT touch any hot oil or hot components.
- Periodic greasing of Puller Rods (10) is highly recommended.
- Inspect all components prior to each use for nicks, burrs, dents, cracks, bends, or worn parts. If damage is found, discontinue use until inspected and released for use by an approved inspector at dealership.
- Inspect all welds and check for damaged, cracked, or bent components.
- Inspect all hardware for damaged threads and cracked or bent components.
Cleaning
Clean tooling after each use, using a non-solvent based cleaner.
Storage
- Remove Pin Puller Assembly from the Bottom Lift Assembly.
- Store the Pin Puller Assembly with Cylinder installed and fully retracted.
- Adapter Assembly may be left installed on Top Lift Assembly.
- Top Lift Assembly and Bottom Lift Assembly should be stored assembled.
- Store tooling in a clean, dry location to prevent rust or corrosion. Tooling can be damaged by moisture or high humidity.
- Tools should be stored in most stable position.
Tool Disposal
At end of operational life of tooling, destroy tooling and dispose of as scrap.
