Professional Shop Manual intent
This manual is intended to provide service dealers
with an introduction to proven diagnostic and repair
procedures for MTD horizontal shaft engines.
Disclaimer: The information contained in this manual
is correct at the time of writing. Both the product and
the information about the product are subject to change
without notice.
About the text format:
NOTE: is used to point out information that is rel-
evant to the procedure, but does not fit as a step
in the procedure.
• Bullet points: indicate sub-steps or points.
Disclaimer: This manual is intended for use by trained,
professional technicians.
• Common sense in operation and safety is
assumed.
• In no event shall MTD or Cub Cadet be liable for
poor text interpretation or poor execution of the
procedures described in the text.
• If the person using this manual is uncomfortable
with any procedures they encounter, they should
seek the help of a qualified technician.
! CAUTION! CAUTION
Caution is used to point out poten-
tial danger to the technician, oper-
ator, bystanders, or surrounding
property.
! WARNING! WARNING
Warning indicates a potentially
hazardous situation that, if not
avoided, could result in death of
serious in
ur
.
! DANGER! DANGER
Danger indicates an imminently
hazardous situation that, if not
avoided, will result in death or seri-
ous injury. This signal word is to
be limited to the most extreme sit-
uations
Fasteners
• Most of the fasteners used on the MTD engine
are metric. Some are fractional inches. For this
reason, wrench sizes are frequently identified in
the text, and measurements are given in U.S.
and metric scales.
• If a fastener has a locking feature that has worn,
replace the fastener or apply a small amount of
releasable thread locking compound such as
Loctite® 242 (blue).
• Some fasteners like cotter pins are single-use
items that are not to be reused. Other fasteners
such as lock washers, retaining rings, and inter-
nal cotter pins (hairpin clips) may be reused if
they do not show signs of wear or damage. This
manual leaves that decision to the judgement of
the technician.
Assembly
Torque specifications may be noted in the part of the
text that covers assembly. They may also be summa
-
rized in tables along with special instructions regarding
locking or lubrication. Whichever method is more
appropriate will be used. In many cases, both will be
used so that the manual is handy as a quick-reference
guide as well as a step-by-step procedure guide that
does not require the user to hunt for information.
The level of assembly instructions provided will be
determined by the complexity of reassembly, and by
the potential for unsafe conditions to arise from mis
-
takes made in assembly.
Some instructions may refer to other parts of the
manual for subsidiary procedures. This avoids repeat
-
ing the same procedure two or three times in the man-
ual.
