AIR BAG REPLACEMENT
If replacement of the track tension air springs become necessary, the following steps must be performed:
1. Slowly remove the air pressure from the rubber bladder.
2. Remove bolts that hold air spring in place and remove air spring.
3. Install new air spring between pressure plates. Be careful not to damage brass air fitting on top of air
spring.
4. Install and tighten bolts on bottom side of air bag using blue lock-tight. DO NOT OVERTIGHTEN as
cracking of plastic base will occur. Bolt torque should be 20-30 ft.-lbs.
5. Slowly fill air bag with compressed air to the recommended pressure in owner’s manual. Stand clear
of any moving parts while filling up air springs. Sudden movement can occur.
TRACK ALIGNMENT
The rubber tracks are held in proper alignment by the front alignment weldment. Track alignment is set at
the factory but may need further adjustment. Rubber tracks require a run in period to seat properly. More
adjustment may be necessary for the first week or two. It is normal for tracks to favor one side or the
other depending on ground condition, contour and carrying weight. If after a suitable time period you feel
the track is misaligned, follow the instructions below.
STEP 1 - Loosen the 3/4” vertical bolt
with 1 1/8” wrench
STEP 2 - Loosen the 1/2” nuts (one
each side) on set screws with 3/4”
wrench
STEP 3 – Correct alignment by
adjusting the 1/2” set screws on each
side of the Tracking Arm using a 1/4”
hex key wrench. If the center guide
lugs are showing wear on one side,
adjust the tracking arm in the direction
of that side. Back the set screw out on
the wear side no more than one full
turn at a time before checking (Step 4).
(Final adjustment may be only 1/8 of a
turn of the set screw.) Force the
tracking arm to that set screw with the
opposite set screw. Tighten both set
screws against the side of the Tracking
Arm. Tighten both 1/2” nuts and the
3/4” vertical bolt.
STEP 4 – Check the Alignment. Pull
the track a short, straight distance.
Touch each side of Guide Lugs. If one
side is warm, then the guide lugs are
still rubbing against the End Idler
Wheel and further adjustment of the
Tracking Arm toward the warm side is
needed. Repeat Alignment Procedure
until Guide Lugs are no longer warm.
When the Guide Lugs on the Rubber
Belt clear both End Idlers Wheels, the
belt is properly aligned.
