Move the idler pulley up and away from the V-belt
and pull the belt out so it is free; then allow the
spring loaded idler to release (Figure 59).
The Toro belt drive system, which is utilized on all 20”
Snowmasters and S-200’s, consists of a crankshaft
pulley, a rotor pulley, a spring loaded idler and a
multigrooved V-belt (Figure 57.). The power from the
engine is transferred from the crankshaft pulley to a
rotor pulley by the multigrooved V-belt. A constant
tension is supplied to the V-belt from the spring loaded
idler.
Note: Do not allow the idler to snap when
released as damage to components may occur.
Remove the drive belt from the impeller pulley and
engine pulley.

The belt that drives the impeller may become worn
after many hours of use. This wear will cause the
impeller to slip. If the impeller slips, the V-belt should
be replaced.

Single Stage Snowthrower Service Manual
5 - 1
(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.
