BELT ADJUSTMENT AND REPLACEMENT
TO REMOVE PTO BELTS
1. Loosen belt guides from PTO support and remove
PTO belts from pulley.
2. Loosen the two capscrews that hold the belt guide
to the engine, and remove the guide.
3. Use wire hook to pull the idler pulley away from
the belt.
4. Remove the drive belts from the engine pulley.
5. Remove the PTO belt or belts.
To install the PTO belts, reverse the above procedure.
Be sure all parts removed are replaced in their
original position.
TO REMOVE DRIVE BELTS
1. Follow steps 1, 2, and 3 listed previously
2. Remove nut and washers from front end of the
drive shaft. (To keep drive shaft from turning while
removing nut, hold it with a wrench across T bar
welded to back end of drive shaft.)
3. Remove the four capscrews and washers that hold
bearing support to the mounting plate assembly.
4. Remove bearing support by sliding it off front end
of drive shaft.
5. Remove drive belts.
To install new belts reverse the above procedure.
Be sure belt guides are properly positioned on the
engine. Locator on back of belt guide should fit into
groove on face of engine.
PTO BELT ADJUSTMENT
The PTO belts can be adjusted by loosening the three
capscrews that hold the PTO support casting to axle sup-
port casting. Raise or lower PTO support casting to
proper adjustment.
If belts are properly adjusted (as described above)
and still drag, check adjustment of lower belt guide.
There should be approximately 1/8" clearance be-
tween pulley and belt guide all the way around.
TRANSMISSION DRIVE BELT ADJUSTMENT
The transmission dual drive belts require no adjust-
ment. There is constant belt tension applied at all
times.
GENERATOR-STARTER DRIVE BELT ADJUST-
MENT
The generator-starter drive belt can be adjusted by
loosening the capsrew on the adjustment bracket

and moving the generator-starter. The belt is prop-
erly adjusted when it can be depressed approximately
1/4 inch under slight thumb pressure.
CLUTCH-BRAKE PEDAL
As you familiarize yourself with the tractor, you
will notice that when you depress the Clutch-Brake Pedal
approximately two-thirds, the clutch is disengaged.
This Clutch-Brake Pedal position also serves as a
brake to stop the vehicle when in gear. Pedal ad-
justment is set at the factory and should not require
frequent attention unless the linkage has been dis-
turbed. Should clutch slippage become evident or
brake shoe lining is worn, see your Bolens dealer.
However, to prevent the vehicle from moving when
transmission is in NEUTRAL or when shifting into
another gear, particularly on inclines, it is neces-
sary to further depress the Clutch-Brake Pedal to
apply the main transmission Brake.
The Transmission Brake, being the main brake,
must be checked frequently and adjusted as follows:
1.
Depress Clutch-Brake pedal approximately
two-thirds (until rear clutch flange has moved back
to touch stationary plate). At that time the adjusting
rod has moved up to top of brake rod slot. (See
Figure 17.)
2. Exert additional pressure on pedal to move brake
shoe shown in Figure 17, toward Main Brake drum.
3. Brake shoe must contact drum when CLUTCH-
BRAKE pedal is approximately 1" to 1-1/2" from
pedal stop on frame. (See Figure 18.)
4. Adjust nuts on adjusting rod to insure adequate
brake shoe pressure. (See Figure 17.)
