Track Adjustment - Check
Lay a straight edge (1) on the track between the top carrier
roller and front idler. Measure the maximum amount of track
sag from the high point of the track grouser to the bottom
of the straight edge. A properly adjusted track will have
approximately 1.375” (1 3/8”) inch (35mm) of slack. Check
for wear and excessive dirt and material buildup.
If the track appears to be too tight or too loose, refer to the
instructions below.
Tighten the Track if Too Loose
1. Using the special grease fitting that was included
with your machine, add grease through the fill valve
fittings located inside the engine compartment on
each rearward side until the correct track tension is
reached.
2. Operate the machine back and forth in order to
equalize the pressure.
3. Recheck the amount of track sag, and adjust as
necessary.
4. An over-tight chain will show on the display panel
warning light and an alarm will sound.
Loosen the Track if Too Tight
1. Loosen the grease nipple with a wrench, twist the
nipple out far enough so that grease begins to seep
out of the cross hole.
2. Retighten the nipple when the desired track tension is
reached.
Track Bolts - Re-Torque
When installing a track, torque the 5/8-18 master link bolts
& the bolts that hold the track pad to the track chain to
224-263 ft-lbs.
Track Drive Mounting Bolts - Check/
Tighten
After the first 50 service hours, check the metric bolts fastening
the track drive motors to the frame for tightness. Remove
the cover and bolts behind the motor to access the bolts.
In addition, check the M16 metric bolts fastening the drive
sprockets to the track drive motors and the M16 sprocket
bolts to the drive motors.
Torque all these bolts to 185 ft-lbs. (250 Nm) in a sequence
that tightens them diagonally across the perimeter of the bolt
ring. (Contact Rayco for further information.)
They should all be checked again after every 500 hours.
Track drive oil - Check
To check the track drive oil the drive unit must be placed in
accordance to fig.4 and plug (3) removed. If oil seeps out of
the hole, the unit is full. When the oil level is below the hole,
fill the unit according to the instructions in the “Track Drive
Oil - Replace” section which follows.
