Re: Digging deaper into my Gearmatic 8a winch

Paul, I cut a new piece of thick felt that is used under furniture to keep the legs from scratching the floor. Thickness seemed to be perfect, with right amount of contact on the shaft, but not too tight. You can find it at hardware stores. It has an adhesive back and comes in a rectangular shape. I...

Re: Gearmatic 8a Winch/Controller Rebuild

Sorry, mental vapor lock - you do not need to install the cover to test the brake circuit, just the clutch.

Re: Gearmatic 8a Winch/Controller Rebuild

As notmeu noted, take the cover off an get a look at how things are working. It's likely that vibration from having the PTO engaged and the crawler running is helping to self-bleeding the air out of the system into the controller reservoir, at least enough to get things working for a while. If it si...

The cylinder rebuilt kits are available through forestryparts.com. The X710 controller used two different cylinders for the clutch and the brake. The later controllers for the 19 used identical cylinders. If your controler worked with the brake plunger without a hole, than it is possible that you ha...

One other item on the controller. If the brass bushing around the handle shaft needs to be replaced, use Loctite 603 on the bushing. The replacement bushing may not be a tight fit if the casting hole is worn. The 603 will seal the bushing to the casting so the fluid does not leak from the reservoir....

Tom, hooks and chokers are on. Also have been using a skidding cone for larger hitches. Easier than a mid 50s Buick hood. Keeps things a little cleaner. Not much snow here and the ground is still too squishy. Wimpy winter so far. Gregjo, thanks. The sugarhouse is a timberframe. We used hemlock from ...

Gearmatic 8a Winch/Controller Rebuild

http://i38.photobucket.com/albums/e133/vtmartins4/IMG_0073_zpsd1tfffnb.jpg Thought I would list some lessons learned on a recent rebuild of an 8A winch and controller. Going to try posting first to test for debug error. As it has been noted many times on the forum, before purchasing a winch, take t...

Gearmatic 8A Winch Closure Plate

Does anyone have a close-up picture or dimensions for the closure plate located on the clutch/brake side and in front of the cover plate? It is held on by two bolts to the winch mounting flange.

Thanks!

Gearmatic 8A Winch Bearings

Finally got the winch torn apart without burning the barn down or loosing any fingers - quite a job. Does anyone have a list of replacement bearings? The parts list only identifies the ring and pinion bearings. I need to replace all the bearings on the shaft. Original bearings are too corroded to re...

Lavoy,

Thanks for the reply - not sure what you mean by a matching back-up - a replacement leather washer?

Thanks.

Rebuilding hydraulic pump. Deere provides four rubber o rings with the seal kit. Not sure where these go. The original seals at the engine driven shaft consisted of one rubber and one leather seal. Assuming replacing both with two new rubber o rings? What are the other two for - seals at line fittin...
