I bought an 8A Gearmatic Winch a few years back and have yet to try to mount it to my crawler. I have a ’59 JD crawler. Looks like it should. I Have a gearmatic 8A and the parts book and operating manual. The manual also covers the 8G. I have been able to get parts from a local JD. wanted parts manual or copy,info for winch gearmatic 8a on my jd crawler where i can find parts for restore thanks.

I still have to take the cable off the drum and then get started. You can find it at hardware stores. I have an air chisel with a blunt end, an acetylene torch, and assorted blocks and big hammers to assist. I tried the hacksaw spacer method to adjust the clutch, but found that my clutch is eccentric, as compared to concentric, meaning that it wants to drag causing the drum to engage and reel-in when it’s not supposed to.
I just picked up a ic with a gearmatic 8A winch. Ray, does your shop do single pours? It’s surprising how low a temp works to get this task done. Try to find an iron foundry around you that still hand molds parts, if you have the part that they can use as a loose pattern it is not much work to reproduce it.
Look before you leap. There is other materials but I do not think they last as long. Don Garrett of Garrett Enumclaw WAhas furnished me with a manual for my winch, and he has some parts. Christmas from me, But is at the moment on a pallet in my garage now thanks to a couple of friends.
Take the cover off, and with a bright light you should see any leaks on the circuit brake or clutch that was under pressure. I guess that destroying the bearing is an option since I have a replacement, so levering against gearmati case would work, but I’m open to other ideas.
I think Mr Data is behind the issue! I soaked the actuator in brake fluid to get it working on mine.
Don’t remember how much it was, but not expensive. Use a combination of heat and tightening of the bolts. Now that you have a winch you will have to build a canopy or some sort of FOPS!!! Any thoughts or advice will be appreciated. When he asked what is was for, he said he did not know Honda made winches. If the brass bushing around the handle shaft needs to be gewrmatic, use Gearmaatic on the bushing. I needed an Allen bolt for the hondu on the drum.
It would pull the Queen Mary around if you could hold the down. It is compatible with brake fluid. The brake adjustment screw is typically a bad place for corrosion. No registered users and 4 guests. Hope the info is helpful to someone in the future.
Not much snow here and the ground is still too squishy. I will try to get my point gearmatlc again Now I need some advice on how best to remove the inboard shaft bearing without damaging the seal.

Next challenge while reassembling is to get the internal fluid lines updated and sealed properly. So, that means no contractions! I’ll probably take the cover off one last time and decrease the clutch gap a bit so that there is a bit more winch-in pull.
IM beond the time in my life to learn this new stuff. It is possible to bend one of the legs which will make adjustment of the clutch bands at reassembly difficult. I do somewhat remember that the bearing only had to move like a inch, then the shaft was thinner so the bearing slid pretty easy until the end where a bearing puller was used.
I’ll have to work on it in the winter, tried to get some parts off it and they are rusted solid, probly how they broke the cover. I happen to have an old electric hotplate that works well too when I put a piece of metal on top of the coils, use low heat, and keep flipping the bearing yearmatic even the heat.
The previous owner said the controls need bled, and that after sitting for long periods you would have to run winch long time until it would engage?? Keeps things a little cleaner.
The brake cylinder will run fluid down the push rod if it is leaking.
Please share your thoughts and experience. Enjoy the fruits of your efforts. Once you get in the habit of going thru those motions Its not that bad at all. A rose bud and even heat is the way to go when trying to remove parts like the clutch lever or the clutch spider.
In the meantime, I’m researching gearmatid availability of the oil seal – federal Mogul No registered gearmatkc and 14 guests. Very helpful individual when it comes to the old winch. It’s handy having part numbers, approximate prices and your thoughts. The sugarhouse is a timberframe.

Also have been using a skidding cone for larger hitches. Still thinking 88a the inboard bearing. Wimpy winter so far. Also, suspect you know this trick, but use the pot warmer on a coffee maker to heat up your bearings so that they slide onto the shaft easily without cooking the bearing seals.
