This Mechanic's Handbook contains comprehensive inform-
ation to properly operate, service, and repair JLO en-
gine models
L
252
and
RM
252.
The repair procedures are described in detail and are
supplemented by useful illustrations.
1.
Each assembly group
is
subdivided into DISASSEMBLY
and ASSEMBLY.
The illustration numbers shown in the general view
on page
1
refer to the individual assembly groups
in the procedure section.
2.
When ordering replacement parts, please refer to
the pertinent spare parts list to determine the
correct part number. If the required spare part
cannot be identified, please describe the part and
state engine model and serial number (shown on
name plate) on your order form.
3.
In case of a complete engine overhaul, please do
not try to save money by re-using worn or defec-
tive parts. It is always more sensible to replace
one part too many than to re-use a part which
condition is doubtful. When repairing an engine
which
is
in poor condition, please use available
shortblocks rather than repairing the engine with
individual parts. This and the use of JLO sub-
assembled repair kits will help to save time and
money.
The part numbers and exact descriptions
of
short-
blocks and repair kits may be found at the end of
the spare parts list.
4.
Always use genuine JLO spare parts!
5.
To secure certain screws or nuts, a thread locking
compound
is
used.
We
recommend to use "Loctite
249",
"Casco
184"
or equivalent.
