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).
