Burned Up Warn M8000 Motor

Well I needed to rebuild my Warn M8000 winch. This past weekend I pushed it to the limit and pretty much burned up the motor. After it cooled it still worked but I have no idea how it will react under load. All I know is it's sticky and it smells horrible.

My question is, should I just trash this motor or try and clean it up and stick it back in? I've already ordered the gaskets, bushings, decals and aluminum tie rods so the rest of it will be fine. I was thinking about getting some brake cleaner and doing what I can with the electric motor. If it doesn't work out then I'll just replace the motor.

don't use brake cleaner on the motor. If you are going to try and clean it up use a cleaner designed for electronics. Your local parts place should have something formulated for cleaning alternators

I'm going to try and find something today. One guy recommended the battery terminal contact cleaner but I don't think that's what I need. I'll try to find actual electronic cleaner if I can.

Unfortunately the more I look at it and think about it the more I'm leaning towards getting a new motor. I think this one is shot and if it does work it most likely won't be as strong as it use to be.

I found a pic of what the inside of the motor should look like and what mine looks like. Gross.

Wow! Hey, That's a bummer. Anyway, If it got all hot and stickey I would think that the insulation around the windings got to the melting point which is now thinner and likely to short out against the adjoining windings due to the thinness of the insulation. Might last or might not with a rebuild.

I agree. I'd go with another motor. Check Ebay I got an OEM motor for a great price.

I'm pretty sure the varnish was toasted good. I saw some coming out onto the drum.

I'll check them out but if I can't find a Warn OEM motor then I'll just go back to them. As of now the new part number for the motor is 77893 and it's $204.78.

I'm still going to clean everything up, paint it, replace the thrust washer, drum bushings, tie rods and clean up all the gears and put fresh grease in. I'll still try to clean the motor up and bolt it back in. If it fails on the trail well that's why I don't ride alone. If it doesn't good for me.

Lou,

Just for the heck of it I sent an email to a vendor on Ebay on your motor. I'll let you know if he comes back with a decent price.

Lou, check out this link on Ebay. I asked the vendo if it was a replacement motor for your M8000 part number 77893 and he responded with this motor for $85.00 with $16.00 shipping. Hope this helps.

Flajeeper,

Will do Eddie. Here's everything degreased and bead blasted. I will pick up some Rustoleum hammered grey tomorrow.

Check these guys out for new winch motors.
They look to be pretty reasonable.

How long and how extensively has you used your winch?

I'm getting a JKU Rubicon - adding front and rear off-road bumpers (so it'll be a little heavier than stock).

I was thinking about cutting costs and getting the warn M8000 (like you have), but the dealer recommended the 9500.

Here are my options:
• Warn M 8000 (82202191ac) = $825
• Warn XD9000i (82202612ac) = $1135
• Warn 9.5ti (82209325ac) = $1375

Any thoughts on which I should go with. I'll do some off roading, not entirely sure how many situations I'll be in that will require a winch, but I want one just in case... I guess having one makes you prone to needing it

Thanks for the advice.
