Engine removal
The design of the 221 series snow throwers provides enough engine access to perform most repair procedures;
however, occasionally the engine may need to be removed. Some of the repair procedures that require engine
removal are:
• Electric starter removal/replacement.
• Any repair that would require removal of the sump cover.
• Short blocking the engine.
To remove the engine:
1. Drain the fuel from the fuel tank.
2. Remove the rear engine cover by following the pro-
cedures described in the rear engine cover section
of this chapter.
3. Remove the top engine cover by following the pro-
cedures by following the procedures described in
the top engine cover section of this chapter.
4. Remove the belt by following the procedures
described in Chapter 3: Auger, Belt and Pulleys.
5. Remove the shoulder bolt that the cable idler
bracket pivots on using a 3/4” wrench.
See Figure 2.20.
6. Remove the upper handle bar mounting screw
using a 1/2” wrench.
7. Remove the nut and bolt (indicated by the arrow in
Figure 2.21.) that secures the ring gear retaining
bracket and the heat shield to the engine block
using a pair of 7/16” wrenches.
NOTE: there is a flat washer under the bolt head
and a thick washer between the heat shield
and the retaining bracket.
See Figure 2.21.
Inset.
NOTE: Starting with the 2011, the 221 series will no
longer be built with this nut, bolt and washer.
