CAUTION:
• Never disrupt liquid gasket bead with transaxle case or
other objects during installation.
• Be careful to align the lever of 5th-reverse fork rod with
reverse gear assembly groove.
35. Rotate input shaft so that bearing and shaft fit each other, and then tighten transaxle bolts ( ) to the specified torque. Refer to
MT-17, "
Exploded View".
36. Apply recommended sealant to the position switch thread and check ball plug thread. tighten them to tran- saxle case to specified torque.
•Use Genuine Silicon RTV or an equivalent. Refer to GI-42, "
Recommended Chemical Product and
Sealant".
CAUTION:
Never allow old liquid gasket, moisture, oil, or foreign matter to remain on thread.
37. Apply gear oil to mainshaft spline.
38. Install 5th main gear (1) to mainshaft using a suitable bolt (A) [M10 x 1.0] and a suitable nut (B).
39. Install adapter plate (1), bushing (2), and 5th input gear (3) to input shaft.
CAUTION:
Be careful with the orientation of adapter plate.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. If the scale controls refriger-
ant flow electronically, the hose fitting must be 1/2 ″-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not re commended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
Precaution for Leak Detection DyeINFOID:0000000005930832
• The A/C system contains a fluorescent leak detection dy e used for locating refrigerant leaks. An ultraviolet
(UV) lamp is required to illuminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo-
rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin-
point refrigerant leaks.
• For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions
and precautions prior to performing the work.
• A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should
only be repaired after confirming the leak with an electronic refrigerant leak detector.
• Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis dur-
ing a future service.

Gauge indication Refrigerant cycleProbable causeCorrective action
Low-pressure side becomes nega-
tive. Liquid tank or front/rear side of
expansion valve’s pipe is frost-
ed or dewed.High-pressure side is closed
and refrigerant does not flow.
↓
Expansion valve or liquid tank
is frosted.Leave the system at rest until
no frost is present. Start it
again to check whether or not
the malfunction is caused by
water or foreign particles.
• If water is the cause, initially
cooling is okay. Then the wa-
ter freezes causing a block-
age. Drain water from
refrigerant or replace refrig-
erant.
• If due to foreign particles, re-
move expansion valve and
remove the particles with dry
and compressed air (not
shop air).
• If either of the above meth- ods cannot correct the mal-
function, replace expansion
valve.
• Replace liquid tank.
• Check oil for contamination.
