Dealer Service - Woods PRD6000E Manuel D'utilisation

The information in this section is written for dealer service personnel. The
repair described here requires special skills and tools. If your shop is not prop-
erly equipped or your mechanics are not properly trained in this type of repair,
you may be time and money ahead to replace complete assemblies.

Before working underneath, read manual instructions, securely
block up, and check stability. Secure blocking prevents equipment from
dropping due to hydraulic leak down, hydraulic system failure, or
mechanical component failure.

Keep all persons away from operator control area while performing
adjustments, service, or maintenance.

Always wear relatively tight and belted clothing to avoid getting
caught in moving parts. Wear sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing, and head; and respirator or
filter mask where appropriate.
BLOCKING METHOD
See "Blocking Method" instructions on page 12.

®
Permatex 3D Aviation Form-A-Gasket or equivalent is recommended as a
sealant.

Spindle Disassembly
1.
Place spindle assembly in press and press shaft down through housing.
2.
Remove seals from housing.
Spindle Assembly
Refer to Figure 17.
Bearing cones and cups are designed to work together. It is important to posi-
tion them so bearing cone taper mates with cup taper.
1.
Lubricate new cups with a light oil. Place them in spindle housing so they
will mate with bearing cones. Cups and cones are a press fit to minimize
wear.
Seat cups securely with a press or place a large drift in the flat lip and
drive them into housing until cup seats against machined shoulder of
housing.
Remove bearing cups from housing by placing a punch in the slots
provided and driving them out. Alternate punch positions from side to
side. Take care to prevent housing damage.
2.
Place bottom bearing cone into spindle with taper positioned to mate with
cup.

■
Improper positioning of seals can cause seal damage. An improp-
erly installed seal will leak and could cause bearing failure.
3.
Identify the open side of the seal containing the spring.
4.
Apply a thin coat of Permatex to the area of housing where seals seat.
5.
Install bottom seal with spring up toward center of housing.
6.
Place seal squarely on housing and select a piece of pipe or tubing with
an OD that will set on outside edge of seal. A tubing with an OD that is
too small will bow seal cage.
7.
Carefully press seal into housing, to prevent distortion to metal seal cage.
Bottom seal should seat firmly and squarely against machined shoulder
in housing.
8.
Make sure seal lip did not roll under. Distortion to seal cage or damage to
seal lip will cause seal to leak. Damaged seals must be replaced.
9.
Insert shaft and bearing through bottom of housing.
10.
Fill housing cavity with a medium grade grease.
11.
Install top bearing on shaft to mate with top cone.
12.
Apply a thin coat of Permatex to shaft area where sleeve will seat.
