Engine Removal/lnstallation
Installation (cont'd)
Engino Inst!llation:
Install the engine in the reverse order of removal.Beinstall the mount bolts/nuts in the following sequence.Failure to follow these procedures may cause excessivenois€ and vibration, and reduce bushing life.
l, Install the transmission mount and bracket, thentighten the bolts on the frame side,
NOTE; Do not tighten the bolts/nuts on the trans_mission side.

7. Perform the following:
. Clean the areas where the driveshaft(s) and theintermediate shaft contact the transmission (dif_ferential) thoroughly with solvent or carburetorcteaner, and dry with compressed air.. Check that the set rings on the ends of the drive_shaft and intermediate shaft click into place.CAUTION: Use new set rings,. Adjust the shift cable (see section 14).. Adjust the throttle cable (see section 11).. Adjust the cruise control cable (see section 23).. Refill the engine with engine oil (see page 8-6).. Refill the transmission with fluid (see section 13,14).
. Refill the radiator with engine coolant (see page10-7).
. Bleed air from the cooling system with the heatervalve open (see page j0-7).
. Clean the battery posts and cable terminals withsandpaper, assemble them, then apply grease toprevent corrosaon.. Inspect for fuel leakage (see section j l).After assembling the fuel line, turn on l) the igni_tion switch (do not operate the starter) so that thefuel pump runs for approximately two secondsand the fuel line pressurizes. Repeat this opera_taon two or three times, then check for fuel leak_age at any point in the fuel line,
