6.22 Adjustment for worn traction disc ring

ments.
* Position snowthrower with auger down and
remove Bottom Pan to inspect disc.
(see Section 7.42)
6.21 Adjustment for Drive System Control
Rod
* The Drive System Control Rod is on the han-
dle at the left side of the operator. Adjustment
is required if engagement is sluggish or if there
is creep.
* Loosen the jam nut, remove hairpin, and dis-
connect control rod from control lever. Turn the
rod counter-clock-wise to lengthen, clock-wise
to shorten. Reconnect the control rod lever.
Slack should be removed and the rod should
be snug. If not, readjust. Then tighten jam nut.
* If this adjustment is not successful, use anti-
seize to lubricate the Hex Short Shaft (page 39
key 28) on the Drive Plate Assembly (key 26).
See Section 7.45 for disassembly information .
* To adjust clearance, use 9/16" nut connecting
the bellcrank to a clutch rod. It is at bottom end
of the Drive Control Rod (p 35 key 36). When a
new rubber ring is installed, this nut is adjusted
so that two threads are showing past the nut.
When the ring is worn, it can be adjusted with
up to 1/2" of rod past the nut. This increases
the force of the drive plate on the rubber ring to
stop slipping. The nut should never be turned
so that more than 1/2" extends beyond the nut.
( See Section 7.43 )
NOTE: If the Plates supporting the Rubber
Wheel Ring come in contact with the Drive
Plate Assembly (p 39 Key 26) extreme wear
may require that these parts be replaced.
* If the rubber ring on the traction disc is
missing chunks, has deep cracks, or is worn so
the rubber ring clamp plates are 1/16" or less
from touching the drive plate in engaged
position, the rubber ring must be replaced.
* If the rubber ring passes inspection, in the
disengaged position adjust the clearance be-
tween the Rubber Wheel Ring and the
Drive Plate Assembly to .125"-.140".
* If there is a complaint that the drive does
not disengage properly, check to see that this
dimension is at least .125".
