6.21Adjustment 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 .

*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".

*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.
