Chinese Winch Brake

Hi All,

I'm hoping someone is able to help me.

I recently bought a second hand 12000lb chinese winch that seems to work perfectly except for one thing - is spools out slightly faster than it winds in.

The previous owner has had the winch apart at some stage, and I'm wondering if the winch brake has been reversed (I have had the brake out and by removing 3 bolts the brake can be reversed).

My problem is, how do I know which way it should be? Has anyone ever dismantled their winch and got assembly photos showing which way the cam action should be?

I have noticed that when the gearbox is off, the shaft that runs through the drum can be held while the drum is spun one way, but if the drum is spun the other the drum locks onto the shaft and it is impossible to hold from rotating with the drum. Which way should it be able to free spin, and in which direction should it lock with the drum?

Thanks for your help,

Tom.

Andrew - did you say you were fitting a 12,000 lb Chinese winch?

Hi there Motherhen,

I have a 12000lb chinese winch from Chump Boy ... I've had it about 18 months. It has done a few (perhaps 6) short recoveries of others, and done quite a bit of gardening (moving fallen timber), but not much.

I took it down to check it out prior to this season's trips and everything seems fine.

Cheers
Andrew.

Tom,

Hopefully the attached link will work and may be able to be 'converted' to your winch. It is for a smaller Warn but the brake assembly is similar - see link.

Tom

I had a similar problem with my Brawn/T Max 9500 winch. It would let go when reaching optimum winching strain and then it would spool out.

A mate and I pulled the winch apart and found that too much gease had been applied to the brake area and the grease had gone hard, stopping the brake from working properly.

It would seem that the brake works on centrifugal force whereby the brake 'shoes' push out when the winding the winch in. Looking at the winch with the brake section on the right hand side the brake 'shoes' should spin out when the gears are moving anti-clockwise so as to hold the gears from spinning loose.

Hope this helps. Sorry no photos.

Cheers

Hi Tom,

As Andrew has hinted at above, I used to import these units.

Now, I have one in my shed at the moment that I can take some pictures of tonight - it needs regreasing and stuff anyway, so this will prompt me to do it.

From memory, the brake only fits in one way. There is a hexagonal shaft coming from one side that slots straight in, and coming from the other side the shaft is notched into a little rectangular shape.

If you have dismantled the actual brake, mabey that has gone back together a bit cockey. I'm sure I have a couple of spare units, so I'll see if I can get a picture of a complete one of those as well.

Are you in Sydney? I don't mind if you want to pop round at some stage to have a quick look. While I don't claim to be an expert by any stretch of the imagination, nothing beats being able to take a working unit apart and seeing how it all works.

Finally, have you checked the warranty on that particular unit? I know Aldi started selling them with a 3 year warranty a while back - thats when we shut up shop!

Email me at 4wd@email.com, or 4wd4wd@gmail.com, and I'm sure we can arrange something.

Cheers,

Chris (er.. I mean Chump).

Chris,

Thanks for your reply.

Unfortunately I'm in Melbourne, but I appreciate your kind offer for me to drop by.

Everything seems to work quite well, it's just the speed difference spooling in and out that prompted me to think maybe the brake had been reversed (it also seemed to groan a little more spooling in than out) - the previous owner was a bit of a fiddler I think and it wouldn't suprise me that he fiddled with the brake.

I'm quite sure the brake is actually working, I'm just not sure how to tell if it has been reversed. Removing the 3 bolts in the brake allows the cam piece to be flipped over, but which way is correct.

If you wouldn't mind taking a photo of the brake itself I should be able to make sure that my cam piece is fitted the same way.

My email is:

tomc199@optusnet.com.au

Thank you very much for your help, it is greatly appreciated.

Tom.

Just out of interest Tom - do you know what brand the winch is?

Hi Motherhen,

The previous owner said the brand was Ecme - I have never heard of that brand before, but if you search on Atlas 12000lb winch, there is a site in the states that sell the exact winch I have.

I assume that a lot of vendors buy the same winch and put their own brand names on them (the previous owner of my winch claimed they are exactly the same as a brawn winch - I'm not too sure of that though).

Tom.

Hi Tom - maybe it is Acme? When i researched winches a couple of years ago, Acme was one of the more common Chinese brands, but today the website doesn't work. Hope you solve the problem. Post 42740 seems to bring up a problem similar to yours.

Just out of interest, what conclusion did you come to on the Acme winches?

I have stripped mine completely and regreased it all and it seems to be a fairly reasonable winch - especially for the money.

I enjoy my 4 wheel driving but I'm not hardcore - I'm not about to winch up 60 degree slopes or anything similar. If I were to rely on a winch continually for things like this I would pay $2000 for a tried and proved unit (like a Warn) but for the obstacles I think I'll need to overcome, I'm confident this winch will serviceable for years to come.

Tom.

Hi Tom - I really can't remember- i think they seemed OK. We considered a number of Chinese winches, but although they may have all been OK for their price, we went with Warn when we were able to get a good one second hand.
