CHAIN TIGHTENER 3.4
Chain Tightener Installation
1
Assemble the left and right chain tightener assem-
blies as shown in fig. C233 on the previous page. Make
sure to place both spacer washers next to the side of the
tightener where the bolt screws in. (Always toward the
outside of the loader). Use Loctite type 609 (red) on the
threaded area of the tightener bracket to help secure the
bolt. Torque the bolt to 180 lbs/ft. (245 nm) The chain
tighteners are offset differently for the left and right hand
side. Be sure to place the tightener assemblies into the
correct housing. The head of the bolt always faces toward
the outside of the loader. (Toward you as you install into
the loader).
2
Install the bolt assembly into the tightener bracket.

Install the support plate onto the chain tightener. The
support plate holes are drilled off center. Install the sup-
port plate so that it extends beyond the chain tightener
bracket on the bolt head side. (fig. C235)

need an extra pair of hands to hold the tightener in place,
while someone installs the 3 flanged locking nuts. Only
hand tighten the nuts.

Place the drive chain around the chain tightener idler
sprocket. Loop it around the drive motor sprocket, and
then install the connecting link to the chain.

Tighten the 3 chain tightener bolts and loosen 1/4
turn. Adjust the drive chain tension as outlined on
page 1-5.
