Engine Removal
CHAPTER 4. ENGINE
This chapter describes the disassembly and reassembly
of the engine, its removal from the chassis, and the
necessary service data. However, except when over-
hauling the crankshaft assembly, transmission, shifter
mechanism, or bearings and oil seals in the crankcase,
it is suggested that engine be serviced without removing
it from the chassis. This will save a lot of time and
labor.
Preparation for disassembly of the engine :
1) All dirt, mud, dust, and foreign material should
be thoroughly removed from the exterior of the
engine assembly before removal and disassembly.
This will prevent any harmful foreign material
from entering the interior of the engine assembly.
2) Before engine removal and disassembly, be sure
3)
you have proper tools and deaning equipment so
you can perform a clean and efficient job.
During disassembly of the engine, clean all parts
and place them in trays in order of disassembly.
This will make assembly time faster and easier,
and insure correct installation of all engine parts.
