BELT/PULLEY ALIGNMENT
20” CCR models have an engine pulley that is held on
with two set screws. Move the engine pulley in or out
to achieve alignment. Tighten the engine pulley set
screws with the square head screw first, then the hex
head screw (Figure 92). Torque both to 120 -150 in·lbs
(1356 N·cm - 1695 N·cm).
While perfection is not required in this application, the
pulleys should be aligned fairly close. Use a straight
edge long enough to run from the lower end of the rotor
pulley to the upper end of the engine pulley. Applying
the straight edge to the two pulleys will indicate how
close the pulleys are to being in line. Within 1/8” of
alignment will provide good belt life.

Powerlite Models
Powerlite Models
The Powerlite models have the engine pulley keyed to
the crankshaft and retained with one bolt through the
pulley into the end of the crankshaft (Figure 93). The
preferred method of removing this bolt is with an
impact wrench. However, if an impact wrench is not
available, any wrench of the proper size will work. It
will be necessary to hold the crankshaft with a vise grip
or other tool to prevent rotation. When installing the
new pulley, install the key in the crankshaft, slide the
pulley half over the key. Apply blue Loctite to the
screw and secure both pulley halves with the
On Powerlite models, neither the rotor or engine
pulleys can be moved inward. However, either pulley
could be shimmed out using spacer washers. Adding a
spacer washer between the hub and rotor pulley or
between the engine pulley and the shoulder on the
crankshaft would shim the pulley outward.
CAUTION: Excessive shimming may cause the
pulley to contact the belt cover. Be sure to test fit
the cover to make sure there is no contact.
capscrew. Follow the steps under "ADJUSTING
PULLEY ALIGNMENT" on page 5 - 15.
The bolt on the engine pulley and the locknut on the
rotor pulley are both counterclockwise to remove.
Note: If you do not have an impact wrench, it may be
necessary to hold the crankshaft or the rotor in order to
loosen the nut or bolt.
During reassembly torque the engine pulley bolt to 225
in·lbs (2540 ± 280 N·cm) and the rotor pulley to 55 ± 5
ft·lbs (75 ± 7 N·m).
Single Stage Snowthrower Service Manual

(3 votes, average: 4.67 out of 5)
Lawn and Garden readers have rated Toro Single Stage Snow Blower Service Manual 4.7 out of 5.0 based on 3 product reviews. EXCELLENT . Hard to find manual and very detailed . Only downside is the pics and wording in pics are backwards , but I can deal with that
The manual provides detailed step-by-step instructions for engine removal and installation but there is nothing in it about repair of the recoil starter. The engine removal instructions will be helpful because the starter is buried behind the fuel tank and engine support bracket. I think my problem is a sticking starter dog but getting to it will be a major project.
