inch gap between bolt and rotor. Bump the thru bolt with
a lead mallet to break the rotor loose (4.5, 5.5, 7, 7.5kW
only) for removal (Figure 6-l 7). If the bearing turns freely
and has no sign of damage do not remove, the fan will be
removed with rotor (Figure 6-18).
NOTE
On 7.5kW, if the rotor seems loose but can not
be removed, see Section 6-3.2.

15.2. Two-Pole Removal (3.5kW). On the 3.5kW, the rotor
is held to the engine crankshaft by right-hand threads on
the crankshaft and in the rotor shaft (engine rotates coun-
terclockwise when
viewed from drive side). These
threads
have been coated with antiseize compound to aid disassem-
bly. To remove rotor,
place a wood block in a trailing edge
of one rotor pole. A sharp, medium force hammer blow to
wood block's end will free the rotor, allowing it to be
turned off by hand (Figure 6-19).

CAUTION
Do not attempt to remove rotor by blocking
engine cooling fan and turning rotor with any
kind of wrench. Damage to fan blades and rotor
may result.
