Maintenance (continued)

Lubrication

At the beginning and end of each season

or after every 25 hours of operation, iubri-

cate unit as recommended beiow.

1. Lightly oil both deflector chute cap

pivot points (D, Fig. 6-4) located on each

side of the defiector chute cap.

2. Appiy oil to discharge chute control

rod pivot points w/here crank enters;

A. Control panel rear lip (A, Fig. 6-5);

B. Support tab on front edge of

control panel (B, Fig. 6-5);

C. Support on left rear end of

snowthrower housing (S, Fig. 6-7).

3. Remove left-hand wheel (J, Fig. 6-4).

Clean wheel shaft and apply fresh bearing

grease to shaft. Reinstall left-hand wheel.

4. Apply oil to bearings on sides of auger

shaft (P, Fig. 6-4). Wipe off excess oil.

5. Clean dirt and remove old grease

from toothed portion on flange at bottom

of discharge chute (B, Fig. 6-4). Apply

fresh grease to worm gear, toothed portion

of flange and flange. Adjust lock nut (R)

and friction shims (S) to help prevent

force of snow discharge from turning

chute. Periodically check tightness of lock

nut (R). Do not overtighten lock nut (R).

6. Lubricate handlebar levers at pivot

points (C, Fig. 6-5) with engine oil or a

non-sillcone spray. DO NOT get oil or

lubricating spray on levers.

7. Apply a few drops of clean engine oil

to pivot points on throttle control lever and

gear shift control lever (D, Fig. 6-5).

8. Remove shear bolts from auger shaft,

then lubricate the four auger grease

fittings (0, Fig. 6-6) using a grease gun

dispensing multipurpose automotive lubri

cant. Carefully and slowly spin auger three

or four times. Reinstall shear bolts.

NOTE: if replacing an auger shear bolt,

order part number 1735625. Only use

auger shear bolts supplied by Bolens.

Other bolts may not shear properly and

could cause damage to unit.

9. Check oil level in auger gear box;

A. Place snowrthrower on smooth,

level surface. Unscrew plug (R, Fig. 6-6)

from front of gear box.

B. Inspect plug hole. Oil should just

begin to seep out of hole. If oil does not

appear, add SAE 90 gear oil until oil just

begins to flow out of hole.

C. Reinstall plug. Wipe oil from gear

box, snowthrower and work surface.

10. Remove bolts (V and W, Fig. 6-7)

securing bottom cover to unit. Remove

bottom cover. Apply a light coating of

grease to shafts (A and B, Fig. 6-9).

Prevent grease from contacting rubber

drive wheel (C) or drippng onto drive disc

(D). If grease should contact these parts,

clean thoroughly to deter slippage and

help assure trouble-free operation.

Wheel Drive Belt Adjustment

To check wheel drive belt tension:

1. Measure length of spring (T, Fig. 6-7)

on lower end of wheel drive control rod

(Z). Squeeze wheel drive control lever.

Hold lever down and remeasure length of

spring. Spring should now measure

11/16 in. +/-1/16 in. (17 mm +/-1.5 mm)

longer than first measurement.

2. If difference between measurements

is not 11/16 in., adjust belt tension:

A. Loosen jam nut (U, Fig. 6-7).

Turn adjuster (X) up the control rod to

increase or down to decrease distance

measured in step 1 (each 1 -1/4 turn of

adjuster will equal 1/16 in. (1.5 mm) of

spring extension).

B. Repeat step 1. If difference in

measurements is not 11/16 in., repeat

adjustment. When measurement differ

ence is 11/16 in., tighten jam nut (U)

against adjuster (X).
