G'day Weyalan. Raven is all Maxwells and we pulled 'em all down and rebuilt 'em a few months back. First up, Maxwell
don't make winches anymore and have sold
all their tooling and spares to Arco-Hutton in Sydney
. They were a great deal of help to me when I needed it and sold
me all the parts
I required except for a couple of bits that are no longer available.
Few points to consider.
Before you do anything, ring Allan Hutton at Arco-Hutton 02 9623 2448 and get him to email
to you the exploded diagrams of each size winch
you need to service or if you email
me I can send to you what I have but our winches are 27STs, 20STs and 24nonSTs. You will need to dismantle before you start ordering parts
for obvious reasons.
winches are pretty easy to pull apart and service, from memory there are no nasty tricks but you have to watch the pawl springs which are tiny and have a mind of their own.
On your cockpit
winches mounted vertically be careful as you pull off the drum. If the winches are badly clagged up inside, all the innards may try and come with the drum until the law of gravity takes over , you get my drift I'm sure, think kerplunk. Order some spares of clutch
springs so that you can afford to lose a few. Ice cream containers are great for the messy bits. Simply dump all the parts in with cleaning
fluid (turps or any common degreaser) and leave over night. Then go back and give 'em a good scrubbing with an old toothbrush, finally thoroughly (and I mean thoroughly) rinse off all the cleaning
fluid in warm water
before reassembly. If you leave any traces of the cleaning fluid on the parts it will react badly with the grease.
When it comes to horizontal mount, another big word of warning. As you undo the screw and start to remove the drum of winches on mast
or boom, have something (bucket perhaps) under the winch
to catch any bits that decide to make a break for freedom. Clutches should also be identified as they MUST go back as they were. Some are clockwise rotation, others anti clockwise.
When reassembling do not go overboard
with the grease. It's a common mistake which does nothing except fill up your winches with grease. Winches should be serviced once or even twice a year depending on usage so you don't need ten years supply of grease.
Importantly, if any of your winches are mounted on metal plates (commonly this is so with mast
or boom mounted winches) make sure you use the correct gunk to isolate the two metals or you will start an electrolytic reaction. Sorry, but I forget the name of the gunk.
Finally, do you have lock in winch handles ? It is again a common problem that standard lock in winch handles do not work
in Maxwell winches. Maxwell chose to use their own unique design and you cannot buy new or second hand maxwell winch handles for love or money
. Arco, however, offer a service where they re machine the drive shafts so that they will accept the industry standard lock in winch handle. It costs around $25.00 a winch and I reckon was money
well spent. We even bought some drop forged chrome winch handles from Arco that are lovely. Expensive but lovely . don't float but lovely.
Have lot's of newspaper, cleaning clothes, paper towel and clean dry rags. Plenty of containers for the bits. We also got one of those cheap
blue plastic tarps and threw that over the cockpit
. Judgng by it's condition when we finished it was a good idea.
I hope that is helpful, any questions by all means get in touch. I have no idea how much winch servicing experience you have but I hope there is not too much of stating the bleeding obvious in the above.
all the best
ps -we were sailing with Invincible the other week. She is, I believe a sistership to Insatiable.
