Suzuki GS500E (1989-1997) [51/221] Installation
the nuts evenly and a little at a time in a
reverse of their numerical sequence until they
are all slack. Remove all the nuts and their
washers, taking great care not to drop any of
them into the crankcase. Discard the washers
as new ones must be used.
6 Pull the cylinder head up off the studs. If it
is stuck, tap ~round1he joint faces of the
cylinder head with a soft-faced mallet to free
the head. Do not attempt to free the head by
inserting a screwdriver between the head and
cylinder block - you'll damage the sealing
surfaces.
7 Lift the head off the block, and remove it
from the engine. Remove the old cylinder
head gasket and the O-rings which fit around
the cylinder head studs (see Illustration).
Stuff a clean rag into the camchaln tunnel to
prevent any debris failing Into the engine.
Discard the gasket and O-rings as new ones
must be used.
8 If they are loose, remove the two dowels
from the cylinder block studs (see illustration
11.7). If eIther appears to be missing it is
probably stuck in the underside of the cylinder
head.
9 Check the cylinder head gasket and the
mating surfaces on the cylinder head and
block for signs of leakage, which could
indicate warpage. Refer to Section 13 and
check the flatness of the cylinder head.
10 Clean all traces of old gasket material
from the cylinder head and block. If a scraper
is used, take care not to scratch or gouge the
soft aluminium. Be careful not to let any of the
gasket material fall Into the crankcase, the
cylinder bores or the 011 pa8$8ges.
Installation
11 If removed, install the two dowels onto the
cylinder block studs (see Illustration).
Lubricate the cylinder bores with engine oil.
14 Carefully lower the cylinder head over the
studs and onto the block (see illustration). It
is helpful to have an assistant to pass the
camchain up through the tunnel and slip a
piece of wire through it to prevent It falling
back into the engine. Keep the chain taut to
prevent It becoming disengaged from the
crankshaft sprocket.
15 Install the eight domed nuts using new
washers and tighten them finger-tight (...
illustrations).
12 Fit a new O-ring onto each cylinder hea:d
stud and press it into its recess in the top of
the cylinder block (see illustration). Check
that they are properly seated.
13 Ensure the cylinder head and block
mating surfaces are clean, then lay the new
head gasket in place on the cylinder block,
making sure all the holes are correctly aligned
and that the UP letters stamped out of the
gasket read the correct way round (He
Illustrations). Never re-use the old gasket.
