 Insert it fully into groove to install.
b. Install piston to connecting rod.  Using industrial use drier or similar tool, heat piston until piston pin can be pushed in by hand without
excess force [approx. 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin into piston
and connecting rod.

 Tighten main muffler mounting bracket bolts in numerical order as
shown in the figure.
CAUTION:
 Always replace exhaust tube gasket s with new ones when reassembling.
 If heat insulator is badly deformed, repair or repl ace it. If deposits such as mud pile up on the heat
insulator, remove them.
 When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
 Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehicle
side. Check each part for unusual interference, an d then tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
INSPECTION AFTER INSTALLATION
 Make sure clearance between tail tube and bumper is even.
 With engine running, check exhaust tube joints for gas leakage and unusual noises.
 Check to ensure that mounting brackets and mount ing rubbers are installed properly and free from undue
stress. Improper installation could resu lt in excessive noise and vibration.

Refer to FSU-13
, PS-17.
INSTALLATION
CAUTION:
Be sure to replace the new differential side oil seal every removal of drive shaft. Refer to FFD-12
.
 Refer to "Removal and Installation"for tightening torque. Install in the reverse order of removal. NOTE:

• Check for the correct installation status prior to removal or disassembly. If matching marks are required, becertain they do not interfere with the function of the parts when applied.
 Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
 Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
 Check appearance of the disassembled parts for dam age, deformation, and unusual wear. Replace them
with a new ones if necessary.
 Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
 In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, observe it.
 Clean and flush the parts sufficiently and blow-dry them.
 Be careful not to damage sliding surfaces and mating surfaces.
 When applying sealant, remove the old sealant from t he mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
 Always use shop paper for cleaning the inside of components.
 Avoid using cotton gloves or shop rags to prevent entering of lint.
 During assembly, observe the specified tightening tor que, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.
