Track Removal/Installation
Tracks may need to be removed
periodically to inspect undercar-
riage components or for replace-
ment 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 undercar-
riage is depicted here. The PT-
70 undercarriage is very similar,
however it has only one row of
stationary inner and outer idler
wheels. Track removal is identi-
cal with this exception. (fig. 6)
Track Removal
1.
Break up and remove any
foreign material from the
cavity between the suspen-
sion rail and the drive table
support. (fig. 4)
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. 5)
4.
Rotate the turnbuckle and
lower the drive table as far
as it will go.
5.
Remove the bolts securing
the outer front wheel to the
hub. Then remove the
wheel. (fig. 6, 7, 8)
