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 fitting of any corrosion
or rubber hose material with a wire
brush. Clean the inside of the hose
thoroughly. Do not use any lubricant
when installing the hose. Lubricant may
allow the hose to come off the fitting,
even with the clamp secure.
Bearings
Bearings are used in the engine and
transmission assembly to reduce power
loss, heat and noise resulting from
friction. Because bearings are precision
parts, they must be maintained with
proper lubrication and maintenance. If a
bearing is damaged, replace it
immediately. When installing a new
bearing, take care to prevent damaging
it. Bearing replacement procedures are
included in the individual chapters
where applicable; however. Use the
following sections as a guideline.
Note
Unless otherwise specified, install
bearings with the manufacturer’s
mark or number facing outward.
Removing Bearings
While bearing are normally removed
only when damaged, there may be
times when it is necessary to remove a
bearing that is in good condition.
However, improper bearing removal will
damage the bearing and possibly the
shaft or case.
Note the following when removing
bearings:
1. When using a puller to remove a
bearing from a shaft, take care that
the shaft is not damaged. Always
place a piece of metal between the
end of the shaft and the puller screw.
See (Figure 40).
2. When using a hammer to remove a
bearing from a shaft. do not strike
the hammer directly against the
shaft. Instead, use a brass or
aluminum rod between the hammer
and shaft (Figure 41) and make sure
to support both bearing races with
wooden blocks as shown.
