I ordered replacement lenses for my General from Oliver Crawlers and once again Chris delivered the goods.  I had a pleasant surprise when I arrived home from my business trip to find them well packaged and safe on my kitchen counter.  It is always a pleasure doing business with Chris. I also have to give a big thumbs up to my wife who allows me to keep tractor parts on the kitchen counter.

Thanks,

Doug

Hello Abe, Welcome to the site. Where about is Washington are you? I'm in North Bend just east of Seattle.
Morton, where SR7 commences at US12

Hello all!
I'm the proud new owner of a 1945 BGS H with a Carco Model EA drum and an Isaacson hydraulic fixed blade. I intercepted it before scrappers got it and shipped it off to become a few new Kia's and got it home this morning. As a bonus I have the service, operating, and parts manuals for the tractor, the engine, and the drum and blade.  Grin It also came with the track adjustment wrench and an Alemite pump for the undercarriage lube.  The only issue that I know I need to address is the hydraulic pump seems to have lost it's prime but it starts and runs great and the clutch and brakes work perfect. I want to change fluids and flush out the gear cases, what else might more experienced owners / collectors suggest? Thanks!

Abe

With over 45 years as an industrial electrician I doubt my theory is wrong. What you are missing is the circuit impedance of a 6 volt starter (windings) is half that of the windings on a 12 volt starter. You won't get half the circuit current unless you have a 12 volt starter also to limit current. If you do not change the circuits resistance to current flow (inductive impedance or resistance) the current will be proportional to the voltage applied. Think about what happens to a 6 volt light bulb if you apply 12 volts to it. It gets brighter and burns out because you increased the voltage without changing the bulbs resistance. Same thing with any 6 volt components on a 12 volt battery, Over current! Ohms Law: Current=Voltage/Resistance, works every time.


My years working as an electrician are equal to your's.  Type of work I did compared to you  is likely different. I guess we will have to agree to disagree.  As I see it, it is a matter of what actually happens in real-world use.   Same starter button with a 12 volt battery has virtually no drop across it, no obvious heat, and the starter spins over like crazy.   Switch the battery to a 6 volt (same size/capacity as the 12 volt) and I get substantial voltage drop across the same push-button switch along with a lot of heat.   Also note that the OEM Delco starter on the HG and OC3 is rated at 500 amps @ 4.7 volts at max draw (2350 watts).  The push-button switch I got is rated for 100 amps at 6 volts (600 watts).  My statement/claim about "twice voltage/half current" was not meant to be 100% accurate. Obviously, if a starter turns over faster on 12 volts then when on 6 volts, more work is being done (not accounting for the heat waste when 6 volt is used).  If I was bored - I guess I could stick an inductive amp meter on the cable and get a reading, but can't say I really care. I already know the push-button suffers from excessive loss when used with 6 volts and does not when used with 12 volts.

One update.  After having three push-button 100 amp rated switchs not work, I went to a local Carquest store. I looked through their electrical catalog and found a push-button switch sold for an American LaFrance firetruck with a 6 volt system. No amp rating given but made for a bigger engine then my HG has. Oddly, they had one on the shelf that may have been sitting there for 30 years. Made in the USA.  Obviously better quality then anything else I'd tried but oddly was not physically any bigger then the others.  Still had 5/16" studs.  Put it in and it WORKS GREAT.  WAY better then the others. Maybe better, more conductive material in the internal contacts.

I will certainly do that.  It looks like I need to rebuild both Idlers and at least one roller.  One can reach in there and wiggle them by hand.  The grousers need to be welded up higher as a previous owner welded 1/2 in plates over the center of each track pad and the grousers have worn down even with those plates.  The brake bands also need to be inspected.  A grease pot was thrown in with an unknown type of grease in it.  More research will need to be done before I use any of it.  This is just the tip of the iceberg of "shovel ready projects" for the little slug and I am enjoying every bit of it!

Welcome. Post some pictures of your machine in the OC-3/OC-4 section when you can. Those three point hitches are rarer than hens teeth.

Good morning all!  I have recently bought a new 1952 Oliver OC-3 with a 4 way hydraulic dozer blade and a 3 point hitch.  It took a while to get it home as everyone wanted to see it when I stopped for fuel and food.

Case in point, I'm still using my original 6 volt starter and delivering twice as much voltage (12v) so the starting current is now almost twice as much as it was with a 6 volt battery.

You have your understanding of electrical theory backward.  Twice the voltage means half the amps.  

With over 45 years as an industrial electrician I doubt my theory is wrong. What you are missing is the circuit impedance of a 6 volt starter (windings) is half that of the windings on a 12 volt starter. You won't get half the circuit current unless you have a 12 volt starter also to limit current.
