CONTROLS/LOCATION AND OPERATION

3 - 8 Single Stage Snowthrower Service Manual

Remove the gas cap and lift the upper shroud off the

machine. Replace the gas cap to prevent fuel spillage

or dirt from entering the fuel system. Now you see the

chute ring, the two chute ring retainers, and the detent

arm and spring (Figure 29). To remove the chute ring,

remove the 4 bolts and nuts that retain the left and right

chute ring retainers.

Figure 29 1854-40

Note: The rear bolt in the left hand chute ring retainer

is also the pivot for the detent arm. This arm engages

the notches in the chute ring to prevent unwanted

rotation of the chute. With the four bolts removed, the

retainers and chute ring will then lift off.

These parts are all plastic to eliminate the need for

lubrication and resist icing.

Reassembly is the reverse of disassembly.

Note: The rounded heads of the carriage bolts must

be on the inside of the chute. The smooth head

prevents snow from building up on the bolt head.

20” CCR Crank System

The third system, used on CCR2000 as well as the

2400, 2500 and 3600 series uses a crank that is

mounted to the handle.

Rotating the handle turns a set of gears that engage a

ring gear that the chute is mounted to. The gears are

contained in a bracket located under the upper shroud.

The chute ring gear rests on a support and is held in

place by two retainers. The chute retainers allow the

ring gear to rotate only.

To access the chute ring and gears:

1. Remove the 3 carriage head bolts and locknuts at

the base of the chute and lift off the chute

assembly.

2. Remove the 2 bolts and nuts that hold the chute

crank rod bracket to the lower handle and draw

the rod out of the upper shroud (Figure 30).
