ENGINE MAIN PARTS - DISASSEMBLY
2 - 14
3.4 Removing the pistons
(1)
Rotate the crankshaft to place the piston being
removed at the top dead center.
(2)
Using a wooden piece such as the stem of a
hammer, push the piston and connecting rod
assembly on the mating face with the connecting
rod cap to remove the assembly from the
cylinder block.
3.5 Measuring the crankshaft end play
With a dial gauge installed onto the end of the
crankshaft, measure the shaft end play.
If the measured value exceeds the limit, replace
the flanged No. 3 bearing.
Unit: mm (in.)

3.6 Removing the main bearing caps
(1)
Place the engine so that the cylinder block
mating surface with the oil pan faces upwards.
(2)
Loosen the main bearing cap bolts. Then,
remove the caps.
(3)
On the front and rear main bearing caps, remove
these using a sliding hammer.
3.7 Removing the crankshaft
(1)
Remove the crankshaft by slowly lifting it
straight up.
When lifting the crankshaft, take care not to
damage the main bearings.
(2)
The main bearings may fall down, making it not
possible to identify their original locations.
Once the crankshaft is removed, place the main
bearings neatly and in the original pairs so that
they can be reassembled back onto their original
locations.
