King shit of turd island
Thought I'd post this as I've searched the internet everywhere and had to make some assumptions to repair these. All in all, I think what I've found will work for the majority of 8-13k Chinese manufactured winches priced under $400 (not counting the house brand winches of brick and mortar stores. Winches of this type are routinely priced in the $450-600 range for the same junk).
Like alot of you, my group of friends are more than occasional wheelers on a budget. Me and many of my friends have bought pick your brand versions of Chinese winches. I've seen HF, Tuff Stuff, Viper, house brand farm supply, x-brands off ebay/scamazon. They range in colors and load capacity, but the through line appears to be the 8-9500 pound pull winches have a 216:1 ration and the 12-13500 pound versions have a 265:1 ratio. The weight ratings seem to vary in these two groups by motor hp/kw only.
I have been given several of these, non-operational. I've also non-oped a couple myself. All different brands and weights. As I hate throwing things away that can be fixed, I've tried to find parts for years to repair these. Recently, my searching turned up with parts. Mainly, a replacement brush holder assembly.
I'll lay out what seems to be common amongst these winches. Geartrain appears to be identical, at least among the same ratio/rating groups. Motors have a tang drive (looks like a big straight bit screwdriver) on the business end. All have a 4 brush motor. All geartrains are filled with shit grease that resembles vaseline. Most versions have an unplated brushholder that rusts instantly, and unpainted surfaces internally, or at least poorly painted. All have a 2 pin overrunning type clutch for the 'automatic brake' that, if it has seen much use, is beat to hell. All have plastic/fiber bushings that support the spool. All have shitty o-rings that 'seal' the motor housing.
As most of these fail due to an electrical problem in my experience long before you bust a gear or junk a brake, I've looked all over for a replacement motor. I may have found one (I'll get to that later) but for the money you can just buy another winch. I did, across the pond, find a Land Rover specialty company that carried something that 'looked' like it would work. As it cost about $38 to get it shipped to the greatest country on earth, I took a chance on it. I also found that the bolts welded to the end of the field windings take a beating (one of them was detached), so I soldered the one that had come off back on. I also cleaned up the inside of the motor housing with a big wire brush and a drill to take out the flaky rust and painted it. I chucked the armature up in a lathe at work and polished the commutator bar (copper part), armature stack (steel part), and the shaft ends. Don't take off material, just clean it up! Then I pulled the bearings (the winch that was my guinea pig had a seized bearing on the drive end). The bearings on this one, and all the ones I've torn down so far, are 6203 on the drive side, and 6202 on the other. 6203 is so common good hardware stores have them (get a double sealed one). The 6202 I got in stock at the local NAPA. I also took the opportunity to clean and reseal the gear case. The 'grease', if you can call it that, looked more like Crisco. I repacked it with synthetic MOBIL1, but if I do it again I'm going to use boat trailer grease (waterproof). Then I sealed the ends with silicone.
When the brush holder assembly came, I was pleasantly surprised to find the new one was zinc plated. None of the winches I've torn down so far were anything more than bare steel. As I've seen several fail due to the brushes seizing in the holder due to rust, hopefully they will hold up better. I did find some minor differences between what I had and this one, but the new one was functionally identical where it mattered. I did have to oblong one hole, which I did with the holder slid back into the motor. Everything else worked fine. I reassembled with synthetic grease on the factory o-rings for now, as I thought I'd be back in it soon to work on it.
Long story short, It verks! (#aVe) She came off the healing bench, no worse for wear, better than ever! Runs WAY quieter than all the new China winches I've been around. Now, the solenoid pack is another story. I have a solution for that on the way. I will update this thread when I get it.
Thoughts: I think if I ever buy a new Chinese winch in this price range again, I might tear it down when it's brand new, repack the gear train with good grease, pull the brush holder and paint it with zinc-rich primer, and reseal both ends with silicone. I think by spending 2 hours doing this, you'd have a winch that would last considerably longer. I hope my fix for the solenoid pack is good, it's significantly cheaper than any alternative I've found so far. I did find a replacement motor from the same place I found the brush holder assembly, but it's way outside the price range of what makes sense for an 'experiment', and the same price you can find a whole new winch.
Also, I have about 6 hours in this. If it took this long everytime, you should just work some OT and buy a new winch. Now that I've done one, I think I can do it again in less than 1/2 the time, depending on what's broken. I have about $65 bucks in it so far, and will have $95 in it when the solenoid solution shows up. If I'd have bought the bearings online, I'd have saved about $15 , or had they been okay I'd have popped the seals and repacked them and saved another $15. I spent more money than I needed to as it was a science project.
If anyone has anything to add, tell me I'm wrong/stupid/wasting my time on China junk, or a cheaper source for parts, or a better way to repair these (especially a replacement motor for cheaper), please post up that information.
Below are a couple of links. One to the brush holder assembly, one to the motor you shouldn't buy, one to the 'solution' to the shitty solenoids these things come with.
