C A U T I O N: When blocking Crawler, be
careful you are not putting any blocks under
the #212C Sprocket of either #212 Rear Drive!!
NOTE: As you work with the Tracks, realize
that the more you can support the "lower strand"
of each Track and keep it flat and close to the
#1218 Idler Wheels (4.5" diameter), the more
slack you will have in the "upper strand" of the
Track to work with!
Remove the #1220 Spring Guard that covers the
#234 Spring (black) on the Track you are
preparing to remove...save Cap Screws and Nuts
for later reassembly.
Loosen and remove the 1/2" Nut and 1/2" Lock
Washer from the extreme end of each #1030 Rod
that is tensioning the Track you wish to remove.
By rotating each
clockwise, Loosen and remove each remaining
1/2" Nut and #236 Washer and its respective #233
or #234 Spring. Slide #215 Front Axle fully
rearward.
With gloved hands begin to rotate the Track
forward. Remember to periodically "rock" the
Track's Control Handles forward & back to relieve
any internal pressure on the Track's Motor. As the
Track is rotated f o r w a r d, insert Track Rods
between alternate mating teeth of the Front Idler's
Inner & Outer Sprockets...keep Rods centered
over their respective Inner & Outer Sprockets.
To ease Track rotation insert a 5/8" diameter x
24" long Lever Rod between two Track Plates and
fully engage the Rod's end on the bottom of the
tube of the #1228 Front Idler.
#1030 Rod counter-
NOTE: Insert the Rod between Track Plates
located at about the 1:00 o'clock position and
rotate Lever Rod downward.
CAUTION: Be careful where you locate
the end of the Lever Rod on the Tube of
Front Idler...you do not want to damage #2061
Grease Fitting. Remember to periodically "rock"
the Track's Control Handle forward & back to
relieve any internal pressure on the Track's Motor.
Depending on the amount of debris in your
Track system, you should be able to insert 5 to 6
Track Rods between the alternate mating teeth of
the Front Idler's Inner & Outer Sprockets...keep
Track Rods centered over their respective Inner &
Outer Sprockets!
When the last Track Rod you installed has
rotated to the 12:00 o'clock position, remove the
Lever Rod and force the forward end of the Track
outward by sliding on the Track Rods.
Stop sliding when the Track's Inner Chain is
centered between the Inner & Outer Sprockets of
the Front Idler...see drawing above. NOTE: For
the sake of clarity the Track Rods are not shown
in the drawing above.
Now in a similar manner, using the Lever Rod
on the Rear Drive, rotate the Track rearward and
remove all the previously installed Track Rods
