Follow this procedure for replacing the front idler
(Figure 5-33):
1. Locate track tension manifold and back the relief
cartridge out of the aluminum block about three
turns until you hear the tension pressure release.
(Page 5-49)
2. Rotate the track so the master pin is at the rear
bottom of the front idler and back up the paver until
the track clears the front idler.
3. Jack up the paver at least two feet off the ground
for enough clearance under the undercarriage
to perform this procedure and stabilize with jack
stands or safety blocks.
Crush hazard! Always use safety
blocks or jack stands when working under the paver
to prevent serious injury or even death.
4. Remove the clip pin from the cylinder rod and idler
bracket. Idler will slide out.
5. Remove the idler bracket and bolt to the new idler.
6. Install idler, ensuring cylinder and clip pin are
aligned properly.
7. Lower sprocket back down toward the track
chain,ensuring the sprocket is about one (1) inch
from the chain.
Perform these additional steps for poly or steel
tracks only:
8. Check that the track chain is full seated with the
drive sprocket and rollers are aligned with chain
center.
9. Tighten the tension relief. (Page 5-49)
10. Lower paver to ground, remove jack and start
machine. Track tensions will automatically adjust
when the machine is started.
11. Ensure the track chain remains fully seated with the
drive sprocket and rollers still aligned with the chain
center.
