Re: Alternator or Generator

I’m in the go with the original system group. Over time I’ve rebuilt my whole 6v positive ground electrical system, and it works reliably. The starter cranks well, and the dozer fires up usually on the initial spins. I did go with a bigger battery cable to reduce resistance while cranking.

Re: 420 left steering sticks

Pulling the final on a small dozer seems more daunting than it really is. The big parts are relatively easy to man handle, and the internals are easy to decipher if you have a manual. Take a slow and deliberate approach. I found the process easier than expected. Just readjusted my clutches and steer...

Re: Logging Arch for my 40c?

For the pulley, I’d suggest welding a short length of choker chain to the top cross member, then just hook in the last slider to it. This will swivel and hold up to the forces while winching. The load will lift and drop easily; just stand clear for safety.

By spinning, I mean barring over in neutral to see what happens. Good luck.

Re: Safety Block - Tracks Seizing

Can you get that side in the air? If so, try spinning that track without a load, slowly. If it binds, as Lavoy says, there is something broken, and if forced, more money and time will be needed. Breaking the track, and pulling a final is not that hard, Good luck.

Re: 420c throwout bearing

Congrats. Now you'll notice how that side is more responsive than the other, and feel a need to go there too. Old iron is addictive. I fire mine up and take a romp from time to time to keep things loose; usually very pleasant. Ocassionally I have to clean the points to get 'er started, but most ofte...

Re: 420 6 volt starter

It's been a while, but I never removed the gas tank to pull the starter. I may have had to remove the starter switch to gain some clearance. Good luck.

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

Never took my blocks off. I've winched some very big butt logs without any indications that these mounts were being strained; the paint has no cracks showing. My winch has pulled the machine backwards multiple times with the brakes locked and the blade down.

Re: 420c throwout bearing

I'll second Ray's comments. Make sure that you free up all the internal parts. Things adjust up pretty well if you do, or will be a pain if overlooked. I replaced bushings, some springs and woodruff keys as well. Wish I had paid more attention to the brake pedal linkages when everything was exposed....

Re: 1010 Crawler Foot Brake

If you have the tracks split already, It's not that hard to pull the finals. I used a painter's scaffold on wheels, a sheet of plywood to roll on, and a chain hoist to do mine ( I've also used a pole tripod lashed together with a hoist to manhandle things like this in the past). A manual will be ver...

Re: 420c throwout bearing

Hi: I tore into my 420s finals a few years ago, and posted here. Click on the pictures, and I think that you'll be routed to my photobucket account, and the pictures will be clear. Hope you find this thread helpful when you get into your finals. Paul http://www.jdcrawlers.com/messageboard/viewtopic....

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.
