My problem turned out to be a bad voltage regulator. Got a new one(my Deere parts guy steered me towards a much cheaper alternative to the one from Deere). Put it on, hooked it up and now my ammeter shows charge when it's running and the battery stays charged. My only question now is, it seems to me...

OK, some answers, some questions, some news. Turns out, as you said, mine is not a 3010 pump. It is the same pump as from a 2355. I got it out, found that the main shaft felt rough when I turned it and seeing as it only has a few hours of actual operation on it since it was gone through last summer,...

I did check the suction screen, down in the bottom of the transmission and that was clear. One strange thing is that my service manual shows the filter that you mention, I think it is in with the crankcase inlet valve. Right next to the stroke control valve anyway, but my pump doesn't have it. Actua...

I had a 4020 with a loader that did the same thing, or if you were working in a tight space, working the loader with the clutch out, you would run out of oil and need to give it a minute with the clutch in to catch up. My 3010 isn't like that and it did pass the "bucket test" by putting out a decent...

I don't have a gauge to measure the flow or the pressure but the transmission pump appears to deliver some thing like the 4 gallons a minute that it should. It definetly puts out a way bigger stream than the main pump. I'm only judging the transmission pump by disconnecting the pipe at the main pump...

Rebuilding a worn pump, like you say, is pretty straight forward if you know what you are doing. But this pump pumps almost no oil at all and what little does come out looks like it has gone through a blender at high speed, almost foamy (not white though, no water). Lavoy, the online parts catalog s...

Good point on the longevity question. On one hand the tractor is the same model year I am (1961), on the other hand I love raking hay with it. With the narrow front end and JD power steering it is unbelievably agile and it is really good on fuel. Seems like you can rake all afternoon on 5 gallons. I...

Has anyone had experience buying reman Hydraulic Pumps? I've torn down the pump on my 3010 (ok,ok, it's a wheel tractor), I even had my JD dealer tear it down and it won't work for long. Charge pump seems to be fine,but nothing from the main pump. I'm going to tear it down one more time but I did se...

Thanks, your tip on the charging question is, like most good ideas, really obvious once someone points it out!

Thanks again.

My starter/alternator guy told me he thinks my 420 isn't charging because I reversed the polarity of the regulator while installing a reman genny. He gave me a sketch of how to reverse it back but it didn't work. Any tips on how to do it, specific to a 420? Any way to check if it is reversed? Any id...

Osha would have a fit if they ever saw it, and I've often wondered if there is a more elegant way to do it, but I use a front end loader to pick up the front of my 420C so I can easily get at the inside adjusters. It does beat being under there with no room to work!

Any "leads" ha,ha on a fairlead for an 8A Gearmatic mounted on a 420?

Hey all,

Have we found a way to share a manual for a gearmatic 8A? I downloaded one for a model 9 from Paccar/Gearmatic but no luck on the 8A. Just found this site and am pretty excited. I have a 1956 420C, four roller with an 8A winch and an inside blade.
