I would try either a strap wrench, or, a pair of vice grips with a thick cloth covering the nut.
Not without removing the head, the pistons can't be lowered past the crankshaft. If you remove the head you can remove the rod bolts at the bottom and push the piston through the top.
Remove the access plate on the floor to expose the trans. disconnect the transfer case shifter as 2 of it's bolts are shared with the shifter on the trans. The bracket is held on to the 2 left hand shifter bolts and will have nuts on the top to remove, it is not possible to just move it out of the way without removing the other 2 bracket bolts further down on the trans. Then remove the 4 retaining bolts on the top of the shifter and pull it out.
You can remove the oil pan from your 2002 Chevy Cavalier, without removing the motor. The oil pan is held in place with retaining bolts.
by removing the head bolts
remove the wheel,remove the brake line,removing the two bolts holding it on and then install opposite of removing.
T-55
No but it does take some weird angles to get to all of the bolts. It should remove without removing the motor mount.
removing the retaining bolts.
By removing some screws and/or bolts.
NO. You will have to remove all the transmission bolts and slide the transmission back enough to get a wrench and your hand between the engine and transmission to remove the fly-wheel bolts.
If it is just the shift knob you want it will turn off ( there may be a jam nut at the bottom to loosen first ) As for the entire shifter, remove the shift knobs, boots, carpet, and the two metal panels at the floor, then remove the 2 bolts and 2 nuts at the top of the shifter housing, then remove the bolts on the side and back of the 4wd shifter bracket located on the drivers side of the trans, once that is done you can kinda move it out of the way without removing the linkage. Now you have access to the 2 bolts on the drivers side of the housing, remove those and the shifter assembly will pop right out.
Yes, they share the same gasket and bolts.
