Track Removal/Installation
Tracks may need to be removed periodically to inspect
undercarriage components or for replacement if worn
or damaged. This section covers the procedure to
remove and install a track on PT 70/80 machines.
Tools required:
• Socket/impact wrench
• Ratchet strap
• Heavy duty hydraulic jack
• Combination wrench
• Long pry bar(s)
• ASV approved jack stands (2)
• Spray lubricant
• Shop vac or Pressure washer
Note: The PT-80 style undercarriage is depicted in this
procedure. The PT-70 undercarriage is very similar,
however it has only one row of stationary inner and
outer idler wheels. The track removal procedure is
identical with this exception. (fig. 4-11)
Track Removal
1.
Break up and remove any foreign material from the
cavity between the suspension rail and the drive
table support. (fig. 4-12)
Note: A shop vac or pressure washer will work well to
remove material from this cavity.
2. Clean the threads on the turnbuckle thoroughly
using a stiff bristle brush.
3. Loosen the lock nut on the turnbuckle and spin it
to the end of the threaded shaft to allow clearance
when the drive table is lowered.(fig. 4-13)
4. Rotate the turnbuckle and lower the drive table as
far as it will go. (fig. 4-14)
5. Remove the bolts securing the outer front wheel to
the hub. Then remove the wheel. (fig. 4-11, 4-15,
4-16)
