ARTICULATION JOINT

m

WARNING: The Terra Gator is extremely

heavy and requires proper handling

equipment to safely spilt it. Failures to

use proper procedures and equipment

may result in personal injury or death due

to crushing. The weight of the Terra Gator

may be as much as 13,100 kg (28880 lb).

NOTE: Put identification marks on all hoses, on all

hose assemblies, on all wires, and on all tube

assemblies for installation purposes. Plug all

hose assemblies and all tube assemblies. This

helps to prevent fluid los, and this helps to

keep contaminants from entering the system.

NOTE: Cleanliness is an important factor. Before

beginning the splitting procedure, the exterior

of the components should be thoroughly

cleaned. This will help to prevent dirt from

entering the internal mechanism.

Park the Terra Gator on a flat level surface.

When replacement of the bearings in the Articulation

Joint is necessary follow the following instructions to

support the chassis

Disassembly Articulation Joint

m

DANGER: During maintenance on the

Articulation Joint be extreme careful.

Disassembly of the Articulation Joint can

give abrupt movements of the front and

rear chassis. This can lead to serious

injury or death.

FIG. 1: Before disammebly

When disassembly the articulation joint follow the steps

below:

1. Remove all hydraulic hoses and electrical wires;

2. Remove the steering cylinders;

3. Disconnect the driveshaft and the cross bearings;

4. Disconnect the lower articulation joint;.

IMPORTANT: Notice the number of shims between the

articulation joint.

5. Disconnect the upper articulation joint;

IMPORTANT: Notice the number of shims between the

articulation joint.

FIG. 2: After disassembly the concetion between the

front and rear chassis.

6. Move the rear chassis backwards as much as

need. Use a moveable jack to move the rear

chassis.

m

WARNING: Be extremely careful when

moving the rear chassis backwards.

Be sure there is nobody in the working

area of the chassis.

Keep a safe distance to other

objects/machines.

m

WARNING: Never leave the rear chassis

on the moveable jack. A jack can loose

this force. Always place supports

underneath the chassis.

connections.

1. Move the rear chassis with a moveable jack to the

front chassis.

2. Connect the upper articulation joint;

IMPORTANT: Use the same numbers of shims as

before the disassembly.

3. Connect the lower articulation joint;

IMPORTANT: Use the same numbers of shims as

before the disassembly.

4. Connect the driveshaft and the cross bearings;

5. Install the steering cylinders;

Troubleshooting

TROUBLESHOOTING

TROUBLESCHOOTING

Any errors in the CAN Buss sytem will be displayed on

the RH EIP panel. See the table follwing the

troubleshooting methods for error code definition. Any

possible errors displayed can be diagnosed by the

following 5 methods:

1. Over Temp/Current

This error signals that the applicable component is

attempting to draw too much current through the I/O

module. Check for a shorted load, s shorted wire, or

swap this component with another. When all other

possible causes have been eliminated, replace the

appropriate Module.

2. Open Load

This error signals that the applicable component is

drawing no current through the I/O module. Check for a

broken wire or faulty connection, an open component,

or swap the component with  another. When all other

possible causes have been eliminated, replace the

appropriate Module.

3. Short to GND

This error signals that the applicable component is

shorted to ground. Check for bare wire or an improper

connection, a shorted component, or swap this

component with another. When all other possible

causes have been eliminated, replace the Master

Module.

4. Short to Bat/OT

This error signals that the applicable component is

either shorted to power, or the module is creating too

much heat. Check for bare wires or an improper

connection, a faulty component, or swap this

component with another. When all possible causes

have been eliminated, replace the Master Module.

5. No error listed

No error code is present and a component is not

working. Check switch or control inputs to the Master

Module. Check continuity on the CAN Buss wires.

Check outputs.
