SERVICE INSTRUCTIONS

Tools required for service:

•  Allen key (4 mm)
•  Screwdriver (small)

 
1.  Remove screws (1).
2.  Remove self-tailing arm (2) and drum (4).
3.  Insert a winch handle. Pull up the drive shaft (5) gently, while turning gear wheel (10)  

and ratchet gear (9) carefully. Remove drive shaft (5).

4.  Remove plugs (5.4), pawls (5.3) and arm springs (5.2). 
5.  Remove ratchet gear (9). 
6.  Remove shaft ring (6). It can be difficult to get the shaft over the top of the base (15).  

By turning and tilting the shaft, it will come off. DO NOT use violence.

7.  Remove gear wheel (10).
8.  To release the roller bearing (7), gently insert a small screwdriver between roller bearing, 

and base (15). Remove roller bearing.

9.  The ratchet gear (11) should be cleaned without being removed from the base (15).

10. Clean all parts in benzine. Remember to clean the gear teeth and roller bearing track 

inside the drum (4).

11.  Assemble in reverse order. During assemble, by the use of a small soft brush lightly grease 

all gear teeth, drive shaft, roller bearing, shafts, pawls, springs and bushings. Pawls should 
only be lubricated with a very thin film of ANDERSEN WINCH GREASE. It is very important 
that pawls can move freely.

 

IMPORTANT: 

When assembling the winch, check the functioning of each pawl by pushing 

the pawl against the spring. The pawls should move smoothly and automatically return to 
their normal position, where the pawls engage with the teeth. If the pawls do not function 

correctly, clean and lubricate the pawls and gears. Check the function of the pawls again to 
make sure that it works correctly. If the pawls do not work correctly replace the springs and 
recheck the functioning. 

Malfunctioning pawls may lead to unexpected release of the winch force resulting in fatal 
injuries to the user and others.
 

Service Kit No: 18 (part. no. 710018) contains spare parts for this winch.

 

Maintenance instructions for PVD coated stainless steel surfaces.

PVD-coated surfaces should be rinsed regularly in fresh water to remove any salt residue, dirt 

or other contaminants and dried gently with a soft cloth. To remove grease or other marks, 

 

a mild abrasive free cleaning agent such as spray-on glass cleaning solution may be used.  
No caustic detergents or other aggressive or abrasive cleaning agents  
should ever be used, as they may damage the surface.
