Step 8: To ensure that both Front Idlers (on each
side) have moved rearward, using a mallet, pound
on each track & front idler in the area shown
below. Do this to both sides. See below. Your front
idlers should have moved rearward during Steps
4-8.

Step 9: To tighten the Drive Chains, start rotating
clockwise the Locknut located on left and right
lower rear of Body. To draw Rear Axle back
evenly, turn one Locknut 1/2 turn, then go to the
other side and tighten the other Locknut 1/2
turn...use this back and forth procedure until both
#1805 Drive Chains are reasonably tight...not
"bow-string" tight, but about a 1/4" of "sag" in
the slack strand when the balance of the chain is
taught. See below.

NOTE: When satisfied that both #1805 Drive
Chains are tightened evenly, retighten the four
Bolts holding the two "Inner" Rear Plates on left &
right side of Body. See the 2 pictures on the left
hand side of the previous page. (Left & Right Rear
Views).
Thoroughly lubricate your Drive Chains at this
time, if you did NOT do it earlier in the process.
Replace Seat Assembly, Arm Rests and Rear
Cover and close Hood...secure all with #1866
"threaded" Knobs.

CHAIN REPLACEMENT
To replace your rear drives chains, first follow
Steps 1-8 on pages 44-46.

screwdriver under the retaining clip, pull upward.
The master connector should now separate fro
mthe drive chain.
Step 2: Fully loosen "Rear Nuts" on both left &
right sides, until the nuts are at the end of the bolt.
