14.Remove all clamps and cable ties that attach wire
harness, hoses and cables to the engine. Note locations
of clamps and cable ties for assembly purposes.
15.Remove five (5) washer head screws that secure
spanner plate to air inlet housing attached to engine
(Fig. 23). For assembly purposes, note the locations of
the five (5) removed screws. Two (2) holes in the span-
ner plate that align with holes in the air inlet housing are
used to secure the CVT enclosure cover. Do not remove
spanner plate from transmission so that the plate posi-
tion can be used to align engine with transmission during
engine installation.
16.Remove four (4) flange nuts and flange head screws
that secure engine to engine mount. For assembly pur-
poses, note that negative battery cable, wire harness
ground connection and lock washer are secured with
the left, front engine fastener.
IMPORTANT: Make sure to not damage the engine,
fuel hose, hydraulic lines, electrical harness, engine
coolant pipes, spanner plate or other parts while re-
moving the engine.
17.Use lift or hoist to carefully remove engine from chas-
sis. One person should operate hoist and a second per-
son should help guide engine out of chassis. Move
engine toward the rear of the machine before lifting to al-
low engine crankshaft to clear spanner plate that is at-
tached to the transmission.
18.If necessary, remove air inlet housing from engine
(Fig. 24).
19.If necessary, remove pump mount from engine:
A. Remove screws that secure oil filter adapter to
pump mount to separate filter adapter from pump
mount. Support oil filter assembly to prevent it from
shifting during pump mount removal.
B. Either disconnect engine wire harness connec-
tors from all electrical components on pump mount
or remove electrical components from pump mount
(Fig. 25).
C. Remove the two (2) screws that secure sensor
mount and pump mount to engine (Fig. 25).

screws that secure mount to engine base. Remove
