Grease Zerk

Idler Bolt

Tensioner Bracket

ROUTINE MAINTENANCE

Auger Shaft Shear Coupler

The auger drive is shear bolt protected in the event
that the auger should strike a solid object.  The auger
driveshaft shear coupler is located on the left side of
the gearbox, under the shield.  If sheared, align the
holes in the coupler flange and install a 5/16” x 1-1/2”
NC grade 2 bolt and lock nut.

If  the  shaft  and  coupler  need  to  be  separated,
unscrew  the  grease  zerk  and  release  the  retaining
steel  ball  through  the  grease  zerk  hole.    Use  the
reverse  of these steps  to  reassemble the  shaft and
coupler.

Transfer Case Adjustment

1. Loosen the idler bolt.

2. Loosen the jam nut on the tensioner bracket.

3. Pull the slack out of the chain by hand only.

4. Tighten the tensioning screw by hand until it

contacts the chain case.

IMPORTANT:

Do not overtighten roller chains.

Tighten only enough to remove slack.

5. Tighten the jam nut to secure the tensioner

bracket.

6. Retighten the idler bolt to prevent the idler from

turning.

NOTE:

The idler can be turned if excessive wear

occurs on one side.
