Re: Digging deaper into my Gearmatic 8a winch - includes pictures

Tom: I haven't been using my dozer much this year. I now have a Case 95xt skid steer, and it gets things done quicker. My winch has an issue with the controller that I need to dig into deeper when it warms up; brake cylinder doesn't activate properly, so It doesn't release or activate correctly. The...

Re: Snowplowing

Good advice already given. My two cents is to be sure to dig out your tracks nightly so the center idler doesn't freeze up if you have one. Ice and frozen dirt turns to concrete that binds to front idlers and sprockets, and adjustor springs. I park on planks too. Have fun.

Re: Digging deaper into my Gearmatic 8a winch - includes pictures

Hi: Glad some of my adventures are of help to others. I found that if I clicked on a picture, I could link to my photobucket account and get a clear picture to view. Merry Christmas, and Happy Wrenching.

Re: Implements for 420C

There are some YouTube videos of crawlers pulling plows. Some show them on firm ground with the plows offset, and others show them with a track in a furrow. I'd think that having the crawler on firm, reasonably level footing would be preferable so that the track wear would be reduced,

Re: JD 420C Track Project

Nice to see this thread still running. I bought a rubber tired skid steer so that I could run back and forth to my daughters property a half mile away by road and do earth works, etc. Tracks like this would mean I could do the same with my 420. If I want to move the dozer, it costs me $40/move. I do...

Re: 1010 steering clutch frozen vs adjustment

Jim and dtoots have given you good info. Like the manual says, a speed wrench is handy for adjusting the throw out bearing. I taped my socket to the wrench so it didn't separate and end up part of the final drive mechanism. If your adjustment efforts aren't satisfactory, It really isn't that hard to...

Re: Gearmatic 8A winch manuals

I'm willing to send a .pdf copy of the Gearmatic 8a/g winch manual to anyone who sends me an email and asks. For free. I was in touch with Paccar years ago and asked about copyright infringement. The person I spoke with then said that they didn't care that I shared. Paul

Re: 1010 steering clutch frozen vs adjustment

Hi: A few years ago I rebuilt my 420's final drives with the help of this board. I've included a link to that project; it includes pictures and discussions that you may find helpful. Best regards. Paul

Re: 6 volt starter problem

Glad you were able to fix your starter. I've had to take apart my switch twice over the years. As you found, the copper contacts will gall and/ or misalign. That switch was probably my first repair on my machine, and one of the least expensive :D . Best wishes. Paul

Re: 440IC Wont run w/o choke 1/2 on

Have you played with the load jet? I'll second Lavoy's thoughts too. There are some pretty small ports in the center tube that plug easily. Good luck. Paul

Re: Digging deaper into my Gearmatic 8a winch - includes pictures

I replaced the clutch fluid lines with new stainless steel and brass fittings, using Permatex thread sealant. http://i460.photobucket.com/albums/qq324/pbuhler/60-20180808_160544_zpscclecsei.jpg I tried the hacksaw spacer method to adjust the clutch, but found that my clutch is eccentric, as compared...

Re: Digging deaper into my Gearmatic 8a winch - includes pictures

Hi: Finally got my winch back together. Rebuilt the controller. It needed a new o-ring and brake cup - 1-1/8" available at Napa. I honed the bores with a brake cylinder hone and used brake fluid as a lubricant. I used self- made paper gaskets glued one side with Permatex gasket shellac, and soaked t...

Re: Getting a 2 cylinder to burn cleaner?

When I first brought home my "dead" dozer, I found that the air cleaner was fully plugged with goo. The previous owner had not cleaned it in years. Once cleaned, the previously "choked" engine belched chunks of carbon for a few days before running better. Smelled better too. An easy check and if nee...
