A drive train (10, fig 1), for a tracked vehicle, comprises a transmission (11) having a transmission output shaft (13) which is selectively engaged with a least one final drive assembly (12) via a final drive input shaft (17). A rotatable location shaft 26 is mounted for axial movement within a bore in the final drive assembly and is coupled with the nput shaft (17). Manual rotation of the location shaft 26 moves it in an axial direction, which moves the input shaft (17) axially into or out of engagement with the output shaft (13). A retention device or cap 60 may be removably fixed via screws 64 to transmission housing (19) in a first position which maintains the input shaft (17) in engagement with the output shaft (13). The cap 60 may be fixed in a second reverse position where it maintains disengagement between the input shaft (17) and the output shaft (13). The cap 60 may have a socket which receives and prevents a screw member 25 from rotating when the cap 60 is in the second position. |
