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.

If replacing the wire rope, the drum is an over-wound, right to left set up, so use left lay wire rope if you can. I soaked the actuator in brake fluid to get it working on mine.
I try to share part numbers when I can since it saves time. 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.

There is a drift dowel that holds the brake band while it expands and contracts that is exposed near the winch drum and drives out from the cable gearmagic towards the cover side – you can see it in your ugh picture. To get the brake band off, remove the actuator located on top of the winch – it connects to the remote control lever that mounts on the fender, and you’ll have access to the top of the rod that Lavoy mentioned.
Gearmatic 8a winch rebuild
I am having an issue with the winch winding in on geearmatic own when under load, causing me to think that my inner bearing s are failing. Other people on this site have been very generous with their ideas, time,experiences, and solutions. Convinced the guy to sell me one. Am I correct in gesrmatic interpretation? Christmas from me, But is at the moment on a pallet in my garage now thanks to a couple of friends. May buy a replacement for this one too while it’s easy to get to now.
Finally got my winch back together. Look before you leap. All the steel work i know of is out of china.
If you go to Paccarwinch. Enjoy the fruits of your efforts.
There are paired alignment screws held with wires that center the bands over the clutch drum that you can’t see yet. The brake cylinder does not. 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. I was surprised to find that the last person had switched the brake side for the clutch side.
Gearmatic 8a Winch – JDcrawlers Messageboard
Next challenge while reassembling is to get the internal fluid lines updated and sealed properly. Who is online Users browsing this forum: Parts and restoration for antique and late model John Deere crawlers. Thanks too for the felting ideas. Unfortunately they have almost no parts available any more.
We both had a good laugh. I still have to take the cable off the drum and then get started.
Good luck and keep us posted. There is other materials but I do not think they last as long. Many of the tactics I used to dig deeper were from recollections of the various posts. 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.
I don’t think it will ooze and seems to work well to date. I am glad that I could help you with with your rebuild, now get some logging chains and put some hooks on those log sliders and get it to work!!!

Will the drum slide off the crown gear side bearing, or will the drum and bearing usually move as a unit? Just starting to study it, any advice or direction on where to start would be appreciated, safety is my number one concern, thanks. They are annoying and problematic. There are almost certainly shops much closer to you though, the trick is finding them.
Once you get in the habit of going thru those motions Its not that bad at all.
If the brass bushing around the handle shaft needs to be replaced, use Loctite on the bushing. Unless it is free, or you can get it for scrap value, walk away if you can not get the cover off.
Use broken hacksaw blades to center the clutch bands in the drum, then tighten the adjustment bolts on the clutch spider. Your write up contains a lot of good information that will be helpful to someone I am sure. The replacement bushing may gearmtaic be a tight fit if the casting hole is worn.
Things are easier to figure out if you gsarmatic see them in diagram. It looks like you’re making progress. So, that means no contractions! Last edited by Paul Buhler on Mon Dec 12, I did have to look thru some of my old photobucket pictures to jog my memory Easier than a mid 50s Buick hood.
