1.11.5 Removing Hoses
When removing stubborn hoses, do not exert excessive force on the hose or fitting. Remove the
hose, 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 (new or old). The lubricant may allow the hose to come off the fitting, even with the clamp
secure.
1.11.6 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.
1.11.7 Removal
While bearing is 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. In addition, place the puller arms next
to the inner bearing race. See Figure 42.
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 43) and make sure to support both
bearing races with wooden blocks as shown.
3. The ideal method of bearing removal is with a
hydraulic press. Note the following when using
