General Disassembly Instructions
Refer to the Product Parts Information Manual for drawings and item numbers
referenced in the ”MAINTENANCE” section, unless otherwise noted.
The following instructions provide the necessary information to disassemble,
inspect, repair, and assemble the hoist. Parts drawings are provided in the Product
Parts Information Manual.
If a hoist is being completely disassembled for any reason, follow the order of the
topics as they are presented.
It is recommended that all maintenance work on the hoist be performed in a clean
dust free work area.
In the process of disassembling the hoist, observe the following:
1. Never disassemble the hoist any further than is necessary to accomplish the
needed repair. A good part can be damaged during the course of disassembly.
2. Never use excessive force when removing parts. Tapping gently around the
perimeter of a cover or housing with a soft hammer, for example, is sufficient to
break the seal.
3. Do not heat a part with a flame to free it for removal, unless the part being heated
is already worn or damaged beyond repair and no additional damage will occur
to other parts.
In general, the hoist is designed to permit easy disassembly and assembly. The
use of heat or excessive force should not be required.
4. Keep the work area as clean as practical, to prevent dirt and other foreign matter
from getting into bearings or other moving parts.
5. All seals, gaskets and ’O’ rings should be discarded once they have been
removed. New seals, gaskets and ’O’ rings should be used when assembling the
hoist.
6. When grasping a part in a vise, always use leather-covered or copper-covered
vise jaws to protect the surface of the part and help prevent distortion. This is
particularly true of threaded members, machined surfaces and housings.
7. Do not remove any part which is a press fit in or on a subassembly unless the
removal of that part is necessary for repairs or replacement.
8. When removing ball bearings from shafts, it is best to use a bearing puller. When
removing bearings from housings, drive out the bearing with a sleeve slightly
smaller than the outside diameter of the bearing. The end of the sleeve or pipe
which contacts the bearing must be square. Protect bearings from dirt by
keeping them wrapped in clean cloths.
