CHAPTER FIVE
ENGINE LOWER END
This chapter covers lower end engine components and
engine removal and installation procedures. Tables 1-3 are
at the end of this chapter.
TOOLS
Engine service requires a number of special tools. These
tools and their part numbers are listed with the individual
procedures. For a complete list of the special tools men-
tioned in this manual, refer to Table 12 in Chapter One.
When purchasing tools from a dealership or parts sup-
plier, be sure to specify the tools required are for the spe-
cific Sportster model being worked on. Many of the tools
are specific to the engine. Tools for other engine models
may be slightly different.
The manufacturer’s part number is provided for many of
the tools mentioned in this manual. These part numbers are
correct at the time of original publication. The publisher
cannot guarantee the part number or the tools in this manual
will be available in the future.
ENGINE SERVICE
Many components can be serviced while the engine is
mounted in the frame:
1. Rocker arm cover and rocker arms.
2. Cylinder heads.
3. Cylinders and pistons.
4. Camshafts.
5. Gearshift mechanism.
6. Clutch and primary drive assembly.
7. Transmission
8. Carburetor.
9. Starter and gears.
10. Alternator and electrical systems.
ENGINE STAND
Most engine service can be performed with the engine
supported in an engine stand. An engine stand permits en-
gine service with the engine removed from the frame. En-
gine work can be performed on a stable platform that
lessens the possibility of engine damage due to droppage or
an unsuitable work surface.
