ENGINE REMOVAL AND INSTALLATION

4 - 6 Single Stage Snowthrower Service Manual

5. The upper shroud/fuel tank is retained by one

screw in each corner. On electric start models

only, remove the three screws surrounding the

starter button (Figure 52). These screws hold the

switch box to the upper shroud. Unless they are

removed the wire harness between the switch box

and the starter motor will prevent complete shroud

removal (Figure 49). Once they are removed the

upper shroud and tank can be lifted enough to

remove the primer line, unplug the wiring from the

switch and the fuel line from the fitting on the

bottom of the tank. Note: There might be a small

amount of fuel in the fuel line. Be prepared with a

shop towel to catch any remaining fuel.

Depending on what work is to be done, the shroud

could hang from the starter rope. If the engine is

to be removed, tie a knot in the starter rope

between the recoil starter and the shroud. The

knot in the starter handle can now be untied and

the rope pulled through the shroud.

6. The recoil side of the engine is supported by a

bracket. Remove the bracket or remove the

locknut holding the bracket to the recoil (it may be

necessary to loosen the bracket to disengage it

from the stud on the recoil) (Figure 50). Remove

the 4 nuts around the crankshaft and slide the

plate off the crankshaft.

7. The engine can now be moved to the right until

the 4 mounting studs clear the side plate and the

engine can be lifted out. (Caution: The choke

arm protrudes through a slot in the lower shroud,

do not damage it when lifting the engine out of the

chassis.) (Figure 51). You may prefer to remove

the lower shroud as there are only two screws

holding it on. Note: There is a second engine

plate on the inside of the side plate, this may fall

off when the engine is lifted out of the chassis.
