First Remove clyinder head 	Now ,the
object is to replace piston and liners not do the bottom end of 
the engine so
simply clamp a vise grip on rhe edge of a liner using the old 
exhaust gasket,
(copper ones) folded over the liner edge so as not to chip or mar 
the inner
surface , rotate engine so that the piston will come up against 
the jaw of the
vise grip and raithe liner out of the block. Do this to all the 
liners so that
you have only piston on their rods looking at you . two pistons 
will be up and
two will be down. put some rags  in the liner holes in the block 
so as not  to
lose any thing in the lower portion of the engine, Remove one of 
the circlips
in the piston side that locates the piston pin and push pin out of 
the rod
end, remove piston. Do this to all pistons. You may freely rotate 
engine while
doing this as you will retime  when you replace head. Now the neat 
part. if
you are replacing with new p&l set or are reconditioning the 
original it does
not matter. First place a piston in the bottom of a liner pressing 
the rings
as they slide into the liner makingsure the end gap do not line 
up. push
piston only far enough in to liner so that the pin hole is still 
open. Put a
circlip in the piston groove on one side of the piston. Start with 
#4 piston
assy and the rod end at top of stroke .Lower piston assy over rod 
and push
home the pin. Insert circlip on the piston and push liner down 
into the block.
Do not forget the liner O ring on the bottom of liner.Obviously 
well oiled
pieces make it easier.Next, put a piece or copper tubing iver a 
head stud with
a large washer on the bottom so as the liner is held down when you 
rotate
engine to bring #3 rod up so you can install the next assy.There 
is always a
tricky part and here it comes. the #2 piston is next installed 
with out the
liner. Now rotate engine to bring #1 rod up and preceed th install 
as before.
Now the problem is to install @2 liner. A large hose clamp is 
needed and a
flexible handle nut driver welded th the screw of the hose 
clamp.Put the hose
clamp around the rings of the #2 piston lower liner carefully over 
the piston
and pressing carefully so as the push the hose clamp down while 
the rings go
into the bottom of the liner. If you lookat the liner bottom you 
will notice
that the inner edge is chamfered so it will easily accept the 
rings.Loosen the
hose clamp completely an withdraw from below the liner. push liner 
into block
and you done. Average time with head removal 6HRs!!! no lifting of
engine, no removal of sump.After you have finished the 
installation Please do
change the oil and filter as you will have antifreeze and dirt in 
the bottom
of the engine when you remove the liners. Ciao  from
