Stud Removal/lnstallation
A stud removal tool is available from most tool suppli-
ers. This tool makes the removal and installation of studs
easier. If one is not available, thread two nuts onto the stud
and tighten them against each other. Remove the stud by
turning the lower nut (Figure 51).
1. Measure the height of the stud above the surface.
2. Thread the stud removal tool onto the stud and tighten
it, or thread two nuts onto the stud.
3. Remove the stud by turning the stud remover or the
lower nut.
4. Remove any threadlocking compound from the
threaded hole. Clean the threads with an aerosol parts
cleaner.
5. Install the stud removal tool onto the new stud or
thread two nuts onto the stud.
6. Apply threadlocking compound to the threads of the
stud.
7. Install the stud and tighten with the stud removal tool
or the top nut.
8. Install the stud to the height noted in Step 1 or to its
torque specification.
9. Remove the stud removal tool or the two nuts.
Removing Hoses
When removing stubborn hoses, do not exert excessive
force on the hose or fitting. Remove the hose clamp and
carefully insert a small screwdriver or pick tool between
the fitting and hose. Apply a spray lubricant under the
hose and carefully twist the hose off the fitting. Clean the
Bearing puller
fitting of any corrosion or rubber hose material with a
wire brash. Clean the inside of the hose thoroughly. Do
not use any lubricant when installing the hose (new or
old). The lubricant may allow the hose to come off the fit-
ting, even with the clamp secure.
Bearings
Bearings are used in the engine and transmission as-
sembly to reduce power loss, heat and noise resulting
from friction. Because bearings are precision parts, they
must be maintained by proper lubrication and mainte-
nance. If a bearing is damaged, replace it immediately.
When installing a new bearing, take care to prevent dam-
aging it. Bearing replacement procedures are included in
the individual chapters where applicable; however, use
the following sections as a guideline.
