ARCO 16 Winch Disassembly

[Loose_Change]

Hi everyone,

I've finally decided to give my old ARCO 16 2-speed winches a complete clean, and to my dismay have struggled to disassemble the winch to access the internal gears. I've attached a few photos, and it seems that there may be a pin holding it together from the bottom.

I've tried giving it a good whack with a pin and hammer (and that didn't work).

Any suggestions from the forum from someone that has come across something similar would be very much appreciated.

Thanks in advance!

Do you see the little (5mm) hole in the top of the round disk? The corresponding one on the other side? This is a retaining nut, and that's how you loosen it. From the ARCO page on maintaining your winch:

Insert a 3/16" screw or a small screwdriver or similar, into one of the two holes.
Insert your winch handle into the Main shaft of the winch and turn the handle against the screw, in a CCW direction, to unscrew the Retaining Nut.
Turn the winch handle in a CW direction to tighten the Retaining Nut.

Thanks GordMay and tkeithlu!

I admit to not having noticed the small hole (for which there is only one on this winch rather than the two mentioned on the ARCO site). I'll give that a try and see how it goes.

Thanks again!
