Ridge Tool Company8
Maintenance Instructions
WARNING
Disconnect spark plug when performing mainte-
nance on rodder or engine.
Torque Limiter
(Figures 4 & 5)
The purpose of the torque limiter is to minimize kinking of
rods and excessive torque through the transmission sys-
tem. Kinking is caused by heavy blockage within pipe and
must be adjusted to no more than 50 ft.-lbs. (600 inch-lbs.).
The torque limiter consists of two fiber discs with one as-
sembled on either side of the drive sprocket A-3569.
When clamped against sprocket, the torque limiter pro-
duces the only connection between drive shaft B-3548
and drive sprocket A-3569.
Torque Limiter Adjustment Using Torque
Wrench
(Figures 4 & 5)
1. Disconnect spark plug wire.
2. Remove 3 screws and guard to expose torque limiter.
3. Back off three cap screws so they do not contact
backup plate. They are now free to be turned by hand.
4. Back off torque limiter threaded ring until it turns freely.
Hand-tighten torque limiter threaded ring against
backup plate.
5. Hand-tighten three cap screws to make contact with
backup plate.
NOTE! This insures that all three screws provide even
pressure against backup late at beginning of
torque adjustment.
6. Insert a
3
/
16
″ hex key or pin through both sides of
chain near drive sprocket to lock chain.
7. Insert torque testing tool into shaft B-3548 and lock in
place with drive pin.
8. Install a 1 inch socket on torque wrench and apply
torque to torque testing tool. Record torque reading at
which torque limiter slips.
9. If torque reading is less than 50 ft.-lbs. tighten the 3
cap screws uniformly and recheck torque reading. If
torque reading is greater than 50 ft.-lbs. loosen the 3
cap screws uniformly and recheck torque reading.
NOTE! Turn cap screws
1
/
4
turn for initial adjustment.
Reduce to
1
/
8
turn or less for final adjustment to
obtain 50 ft.-lbs. reading.
