winch pto winch mounting plate
Hello all, I recently picked up a gearmatic model 10 winch. I would like to make it work on my 420, after changing the mounting plate. Does anyone have any photos they would be willing to share of the mounting plate behind the winch on a 420?
And finally for anyone that has a 1010 with a winch or any gearmatic winch for that matter. Do You have a accumulator? From what I understand the accumulator is normally plumbed into the brake release line to aid the brake releasing so it does not get burnt while winching in under load. I do not see a accumulator in the gearmatic which manual at all, but I was told there one. Any help would be greatly appreciated!

Thanks to pop pop for his help with photos. I now understand how to properly mount a winch to a crawler. I have not see too many photos on this website so I thought it would be a good idea to share the photos. I also have gearmatic model 10 manuals that I can email if anyone would ever need them.
If anyone has this adapter plate and you would be interested in selling it please let me know!
Also a special thank to Ralph Newman! He is a great asset for parts, original manuals, information and a lot of advice for these old crawlers!
Tractor mount side, A splined coupler would be needed to connect to the bottom pto shaft.
Winch mount side, the large gear would mate up with this gear, this side is in a gear oil bath.

Thanks for posting these pictures. I've never had my 8a winch off my machine, and seeing the guts is helpful in understanding the internal connections. Does the winch side of the adapter get oil from the winch, or some other way? Thanks. Have you figured out where the accumulator fits in? Paul

Winch side is it's own reservoir as far as oil.

Paul, from what I was told the yellow painted area on the 2nd photo is where the gear oil should be. If you look closely underneath of the gear at the 6 o'clock position, it looks like a drain plug. Actually you can see it better in the 1st photo, bottom of the picture, centered in the plate. Where it is filled looks like at the top left of the 3rd photo but, I do not have a mounting plate yet to know for sure. I still need some internal winch parts to make or find until even think about mounting it to the tractor.Paul Buhler wrote:Thanks for posting these pictures.

Paul, when the winch and adapter bolt together, they create a chamber in which the 2 gears run in oil.
the rest of the winch gearing runs in oil too as Lavoy stated, again in its own chamber.
now i dont see a seal between the two ,and it does state in the winch manual that seepage occurs between the two and that oil levels have to be checked after half hour running or until oil level is maintained.
there is no external filler on the adaptor.
so to answer your question, yes, oil comes into adaptor from winch.

Thanks for the updates guys.
On another note, what clutch clearance has worked for people? I have mine set at .008 as suggested in the manual, and it seems too close. On a logging site, some use .020 on a series 19 winch (didn't find anything specific to the 8a). Sometimes my winch will spool in on its own when set to hold and the machine is moving which can cause problems. Seems like the clutch is catching and more clearance would be good, but how much is enough without being too much? The winch usually free spools correctly; an easy pull with a slight drag. As usual, thanks for your thoughts. Paul

More clearance is nicer for freespooling and not dragging, but downside is less pulling force depending on how good your master control unit is.
You also can have some difference on the narrow and wide clutch bands too. Seems like there is no good figure that works for all, trying opening yours up a little and see.

Lavoy: Thanks for the feed back. Since I can disassemble my winch clutch/brake side easily now that it's been done a few times, I'll try a bigger gap on the clutch; probably start with .012. My winch is a strong pulling unit and recently I've been pulling some pretty big pine and maple (remember it's a 420) up some steep inclines quite easily and it will drag the crawler backwards easily if I don't choose a good path. I want to get the settings right for safety reasons; I like my hands the way they are.
I'll start a new thread if I have any further questions on this clutch setting topic. Notmeu good luck getting yours up and going. Paul

If you are splitting the winch at the adapter plate, you need to slide it to one side to get the drive gear from out behind part of the adapter plate. Don't force it, you can break the adapter.
