There are a a few different paths that can be followed when disassembling an engine. This chapter will cover the
removal of components in one order, but it is written so that the technician can jump around to the component being
removed.
The first step to disassemble the engine is to remove the engine from the application by following the steps
described in the service manual for that particular application.
NOTE: The MTD engine is NOT to be opened under warranty. If an internal engine failure occurs during the
warranty period, replace the whole engine, no short blocks.
