9.1 Introduction
This chapter contains a description of the disconnect that is integrated into the gear drive and the proper engaging and disengaging procedure. Please observe the related "Notes on Safety".
9.2 Description of Disconnect Mechanism
The disconnect of the GFT 60 T3 9139 allows the machine to be towed. The gear drive and hydraulic motor are disconnected when the mechanism is activated.
The integral parking brake in the gear drive is nonfunctional when the gear drive is in the disengage position.
9.3 Disengaging Procedure

Spare part drawing 1/6140/1139/1
Prior to operating the disconnect the machine has to be on level ground and completely secured from any movement, i.e., via tow bar to pulling vehicle. The machine should not be moved unless it is secured to the towing vehicle to prevent runaway.
Ensure that the disconnect mechanism is only operated with the machine at standstill.
The gear drive temperature should be checked prior to any work being done. This is important if the gear drive has been recently operated since it may be hot and cause injury.
- * Ensure that the area surrounding the disconnect is cleaned prior to operation.
Observe that dirt or other contaminants do not enter the gear drive.
- * Remove the 2 hex head bolts M8 x 30 (item 109).
- * Remove the 2 hex head bolts M8 x 8 (item 110) and store.
Hex head bolts (item 110) will be required again after engaging process has been completed.
Install the 2 hex head bolts M8 x 30 (item 109) into the threaded holes in the shift sleeve (item 103) that previously contained the hex head bolts M8 x 8 (item 110). Tighten the bolts (item 109) until they are flush with the shift sleeve (item 103).
The input shaft (item 102) and sun gear (item 88) are now disconnected and the machine is ready to be towed.
The max. gear drive towing speed of 50 rpm must not be exceeded.
During the towing the max. gear drive temperature shall not exceed 90° C. (Check with temperature gauge).
Before the machine is separated from the towing vehicle, either the gear drive has to be reengaged (see paragraph 9.4) or suitable measures must be taken to secure the machine from movement.

- * Ensure that the area surrounding the disconnect is cleaned prior to operation.
Observe that dirt or other contaminants do not enter the gear drive.
- * Remove the 2 hex head bolts M8 x 30 (item 109).
- * Press in shift sleeve manually until it makes contact with the surface of the end cover (item 100).
The gear drive might require minor repositioning to allow for proper spine alignment on the input shaft (item 102) and sun gear (item 88) to engage.
Do not operate the hydraulic motor to obtain engagement.
- * Install the two hex head bolts M8 x 30 (item 109) into the through holes and into the end cover threads (item 100). Tighten the bolts (item 109) until they are flush with the shift sleeve (item 103).
- * Install the two hex head bolts M8 x 8 (item 110) into the threaded holes in the shift sleeve (item 103) that previously contained the hex head bolts M8 x 30 (item 109).
Engaged Condition.
Check the shift sleeve (item 103) to ensure it is flush against the end cover (item 100) and that all components are returned to their original position.
- * The gear drive should now be reengaged and the machine can be disconnected from the towing vehicle.
