Final Drive on LS 160. HELP ASAP

[msudairyfarmer]

Hello All, I have an LS 160, the big sprockets and chains need to be replaced. The small double stack of sprockets on the gearbox shaft look good. Right now the machine shakes sometimes as you can feel the chains jump. How bad of job is it to change the big sprockets? Anyone have any tips? I wasn't sure if there is enough clearance to "roll" them towards the service access panel or do the drive sprockets get in the way? Any help is appreciated

Are the sprockets shot? Is the chain that worn? You know you can take up slack somewhat by moving the axle.

This is the basic operation from the book.
Securely block the skid-steer loader with all four
wheels off the ground. Refer to Section 00 for
more detail information on properly supporting a
skid-steer loader.
Support the loader at the front of the final drive
cases at 1, and at the rear at 2.​

CAUTION​

Failure to securely support the skid-steer loader
could result in movement of the loader causing
serious injury or damage to the equipment.​
