Connector".
3. Remove the harness from the transaxle.
4. Remove the four drive plate to torque converter nuts. NOTE:
Rotate the crankshaft clockwise as viewed from front of engine
for access to drive plate to torque converter nuts.
5. Put matching marks on the drive plate and torque converter alignment stud. CAUTION:
For matching marks, use paint. Never dama ge the drive plate or torque converter.
6. Remove the transaxle to engine and engine to transaxle bolts.
7. Separate the transaxle from the engine.
8. If necessary, remove the following from the transaxle: • CVT fluid charging pipe
• Engine mounting bracket (LH)
• Fluid cooler tubes
• Air breather hose
• Any necessary brackets
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transmission you must make sure any dowels are installed correctlyduring re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.
• Do not reuse O-rings and copper washers.
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.

FUEL PUMP
DescriptionINFOID:0000000005930124
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine
start ability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows
that the engine is rotating, and causes the pump to
operate. If the engine speed signal is not received when
the ignition switch is ON, the engine stalls. The EC M stops pump operation and prevents battery discharging,
thereby improving safety. The ECM does not directly dr ive the fuel pump. It controls the ON/OFF fuel pump
relay, which in turn controls the fuel pump.

BALANCING WHEELS (ADHESIVE WEIGHT TYPE)
Preparation Before Adjustment
Remove inner and outer balance weights from the r oad wheel using releasing agent, remove double-faced
adhesive tape from the road wheel.
CAUTION:
• Be careful not scratch the road wheel during removal.
• After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
Wheel Balance Adjustment
• If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and skip Step 2. below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2.
to calculate the correct size adhesive weight.
1. Set road wheel on balancer machine using the cent er hole as a guide. Start the balancer machine.
2. For tire balance machines that only have a clip-on (ri m flange) weight mode setting, follow this step to cal-
culate the correct size adhesive weight to use. When inner and outer imbalance values are shown on the
balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that
should be used. Select the outer balance weight with a value closest to the calculated value above and
install in to the designated outer position of, or at the designated angle in relation to the road wheel.

O-Ring Specifications*
* : Always check with the parts department for the latest parts information.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
• When the compressor is removed, store it in the sam e position as it is when installed on the vehicle.
Doing so will cause oil to en ter the low-pressure chamber.
• When connecting tubes, always use a to rque wrench and a back-up wrench.
• After disconnecting tubes, immediately plug all op enings to prevent entry of dirt and moisture.
• When installing an air conditione r in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for con-
nection.
• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
• Always replace used O-rings.
• When connecting tube, apply the speci fied A/C oil to circle of the O-rings. Be careful not to apply oil
to threaded portion. Refer to MTC-96, "
Oil".
• O-ring must be closely attached to dented portion of tube.
• When replacing the O-ring, be careful not to damage O-ring and tube.
• Connect tube until you hear it cl ick, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
• After connecting line, perform leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
