John Deere 100 Log Arch

ImageThought a picture of a working John Deere 100 Log Arch would be of interest. The combination of the Gearmatic 8A winch, the log arch, and the 420, work pretty well in the woods. A roller fairlead for the winch would be a great addition, if anyone knows of one!

Re: 420C PTO Issues

Gus, Thanks. I think the problem is PTO power shaft assembly within the transmission. When using a winch on a crawler, the PTO attachment, like on your tractor, and the end plate that covers the differential are removed. An adaptor plate is bolted to the rear of the crawler, with a coupler that conn...

420C PTO Issues

I have a 420c with a Gearmatic 8A winch I use for logging. Towards the end of the winter I heard a noise that I thought was coming from the winch. I removed the winch and the adaptor plate, and didn't find any issues with the winch. Next check was the PTO/power shaft. The shaft "growls" when rotated...

Re: Gearmatic 8A winch for 1010c

John, My suggestion would be to get the clutch band adjusted as close as possible before using it with a load. 5 or 6 pieces of broken hacksaw blades placed between the band and the drum around the circumference of the clutch band is a method that might help. Essentially multiple feeler gauges that ...

Re: Gearmatic 8A winch for 1010c

John, I rebuilt the master control (x-710) for my Gearmatic 8A winch several years ago, and may have had the same issue you are having. After putting things back together, everything worked fine on the clutch side, but is was apparent that the brake cylinder was not getting any brake fluid past the ...

Re: 420C Oil Pump Set Screw Question

Thanks for the replies. The screw broke off below the face of the block, so there are not a lot of threads holding the screw. Tight now, but don't want chance it. I will see if I can get something through the drain hole and hold the pump up that way.

Thanks.

420C Oil Pump Set Screw Question

I need to replace the oil pump set screw and the cover cap (broken off by an old dump rake tine caught in track pad). I can get the old set screw out; the question is can I hold the oil pump in place by keeping the distributor shaft tight in rotation against the slot at the top of the oil pump so it...

'57 420w Dual Stage Clutch Alignment Tool

Checking in for some help. When moving the 420w out of the way of the 420C steering clutch replacement project, an adjusting screw in the 420W's pressure plate snapped, and I had to split the tractor to replace it. I need an a two stage clutch alignment tool to get things back together. I posted on ...

Headlight Gasket Source

Anybody have suggestions for gaskets for 40/420 headlight lenses between the glass lens and the retainer band? Trying to avoid the caulk/roofing cement approach.

Thanks,

Re: Diagnose the problem??

Try looking a your fuel bowl and the filter screen. Might have stirred up some crud in the bowl or from the bottom of the tank with the steep grade and it got caught up in the screen. Also, I have found that long steep grades can lead to fuel starvation if you are low on fuel.

Re: Logging Arch for my 40c?

If you do a search on John Deere’s #100 Log Arch, it might give you some ideas. The were made specifically for the 420/430/440 crawlers in tandem with the Gearmatic 8A winch. It basically moves the winch mounted arch onto a set of wheels, with a roller pulley and the fairleads mounted up high on a “...
