Troy-Bilt 12214 - 5.5HP Forward Clutch Bail Adjustment, D C A, To Check Reverse Belt Tension

Section 5: Maintenance

WARNING Before inspecting, cleaning or servicing the unit, shut off engine, wait for all parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.

from turning by gripping the upper end of the threaded adjuster (B) with pliers.

6.Repeat Step 3 to measure the length of the clutch bail spring. Once the length is correct, retighten the hex nut against the top of the adjuster.

Forward Belt Replacement Information

If the forward drive belt needs to be replaced, see your local authorized dealer or refer to your Parts Catalog for ordering information. Use only a factory-autho- rized belt since an “over the counter” belt may not perform satisfactorily. The procedure requires average mechanical skill and common hand tools.

FORWARD CLUTCH

BAIL ADJUSTMENT

If the Forward Clutch Bail does not function properly, first check that the forward drive belt is adjusted properly (see “Checking and Adjusting Forward Drive Belt Tension”). If this fails to correct the problem, contact the factory technical service department or your authorized dealer for service advice.

CHECKING AND ADJUSTING REVERSE DRIVE BELT TENSION (Models 12191 and 12193 only)

Maintaining correct tension on the reverse drive belt is important to good performance and long belt life. A loose belt will slip on the engine and transmis- sion pulleys and cause the tines and wheels to slow down – or stop com- pletely – even though the engine is running at full speed. A loose belt can also result in premature belt wear.

If there is no reverse action when the Reverse Clutch Control knob is pulled out, then the belt tension is too loose.

When checking belt tension, also check the belt for cracks, cuts or frayed edges and replace it as soon as possible.

•Check belt tension after the first two hours of break-in operation (new belt).

•Check belt tension after every 10 operating hours.

To Check Reverse Belt Tension:

1.Be sure that the engine is stopped and the spark plug wire is disconnected and moved away from the spark plug.

2.Remove the screw in the plastic belt cover and slide the cover (which is attached to the forward clutch cable) out of the way.

3.Have an assistant pull the Reverse Clutch Control knob all the way out and hold it in that position. Measure the length of the cable wire between the end of the threaded cable adjuster (A, Figure 5-5) and the end of the Z-fitting (B) to which the cable wire is attached.

4.The belt tension is ideal if the cable wire length measures between 1/8" to 1/4". If the length is less than 1/8" (and if there is no reverse action when the tiller is running), then make the following adjustments. NOTE: If the length is more than 1/4", no adjustment is needed, as long as the reverse action functions properly.

5.Release the Reverse Clutch Control knob. Unthread the inner jam nut (C, Figure 5-6) one to two turns and pull the threaded cable adjuster (A, Figure 5-6) to the left until the inner jam nut rests against the bracket.

6.Prevent the inner jam nut (C) from turning and tighten the outer jam nut (D) against the bracket. Prevent the outer jam nut (D) from turning and tighten the inner jam nut (C) against the bracket.

7.Measure the gap by repeating Step 3. Readjust as needed by repeating Steps 5 and 6.

8.Reinstall the belt cover.

Reverse Belt Replacement Information

If the drive belt needs to be replaced, see your local authorized dealer or refer to your Parts Catalog for ordering informa- tion. Use only a factory-authorized belt as an “over the counter” belt may not perform satisfactorily. The procedure requires average mechanical ability and commonly available tools.
