1910. Model 2110 Is similar
except that It has a four
cylinder engine. Cylinder
head used on Model 1900 is
simiiar except renewabie

used.

original location. Loosen cylinder head
nuts or cap screws alternately a half
turn at a time to prevent distortion of
cylinder head, then remove head from
engine.
Use a valve spring compressor and
remove valve keepers, springs and
valves from cylinder head. Remove glow
plugs.
On 1210 and 1310 models, top
prechambers (18-Fig, 47) from under-
side of head or use a suitable puller to
remove from head. On 1100, 1110,1200,
1300,
1510 and 1710 models, unscrew
retaining ring (16-Figs. 45 and 48),
then tap prechamber (18) from under-
side of head or use a suitable puller to
remove from head.
Thoroughly clean the cylinder head,
then check for cracks or other damage.
Use a straightedge and feeler gage to
check cylinder head for flatness. Resur-
face or renew cylinder head if warped
more than 0.12 mm (0.005 inch).
On early 1100, 1200, 1300 and 1900
models, cylinder head gasket and shims
were used to adjust clearance between
the top of pistons and the cylinder head.
The practice of using shims was discon-
tinued and cylinder head gaskets are
cleaner (if necessary) and intake
manifold. Disconnect upper radiator
hose and bypass hose (if used). On 1210
and 1310 models, remove the water
pump. On all other models, remove ther-
mostat housing. On all models, remove
muffler and exhaust manifold. Remove
injector nozzles and immediately plug all
openings in fuel system to prevent en-
trance of dirt. Remove the external oil
line to cylinder head on 1210 and 1310
models. On all models, remove valve
cover, valve rocker arm assemblies and
push rods. Be sure to keep all valve com-
ponents in separately marked containers
so they can be reinstalled in their
