Re: 350 snow calk questions

Hi, My 420c has had calks on since, oh, 1966 when Dad put them on. They don't do anything but poke little holes. The grousers do more tearing up. Well, dozer grousers. Not loader ones. The calks will save you in the winter plowing snow on the driveway on a hill. That is for certain. And why Dad inst...

Re: starter keeps turning

Hi, I doubt it is a short. Shorts equal smoke. I doubt it is the solenoid or it would do the same on the bench. That doesn't put a mechanical load on the gear though. If there is too much play between the gear and the starter shaft, the load of turning the engine will bind the gear and not allow it ...

Re: starter keeps turning

Hi,

I am reading all this. But I do not recall any details of the starter used on the Detroit.

I am guessing that wear between the shaft and the gear is allowing the gear to bind on the shaft and preventing it from sliding back.

Re: 1010 Reverser

Hi,

Wait. What? There was some fix that was easy and simple? (!)

It's Party Time!

Of course, I notice the water pump bearing sent the fan thru the radiator just after.....

But, still. Something was easy to fix on Old Iron! Whoot!

Re: '73 - 450B Crawler/Loader/Hoe Restoration

Hi,

Sounds great!

On the dangling engine, keep in mind they have an axle in front to hold it up, but then the engine holds the transmission up. Wonderful idea, the stressed casting. Don't need a frame that way. One more thing to get in the way!

Re: ROOSA Injector Pump Q / Berry Creek

Hi, Fuel comes out when you remove that cover, so that is normal. Sounds like a plugged tank vent to me. This is what it all looks like: http://www.jdcrawlers.com/messageboard/viewtopic.php?f=2&t=13107 Try loosening the tank cap when it begins to die. If that straightens it out, run a wire thru that...

Re: Oh crap!

Hi,

Problem is, without the plate the filter slides down from the spring in the dome and the filter then bypasses. And the plate sticks to the bottom of the filter from the oil, so they are frequently tossed with the old filter.

Re: 420-crawler new voltage regulator 6 volts

Hi, Some 12v coils are wound 12v. Some are wound 6v with a resistor inside. Doesn't matter as either way results in being happy on 12v. What is unhappy is being wound as 6v and not having a resistor and then fed 12v. Many old car coils are 6v with a resistor so that resistor can be bypassed when the...

Re: 420-crawler new voltage regulator 6 volts

Hi,

Yes, you need a resistor if you are keeping the original coil. Or you can change it to a 12v coil.

Re: 420-crawler new voltage regulator 6 volts

Hi, Yep. Regardless of voltage, a generator needs to be polarized to match which side of the battery is used for ground. 6, 12 or 24. And there were some 32, 36 and 48 volt as well. Just not on our machines we chat about here. The norm is 6v is positive ground and 12v is negative ground. But the ear...

Re: 420-crawler new voltage regulator 6 volts

Hi, There are mild steel plates associated with the field coils in a generator. What you are doing is making them into a mild permanent magnet. Setting one end North and the other end South. Like the poles on the planet. Hence the term Polarization. That is where the initial magnetic field comes fro...

Re: Snow!!

Hi,

We had our first snow here in NC. 2 1/2 inches. It didn't need plowing with a tractor, much less a crawler.

Re: 40C All fuel running on 75% diesel

Hi, The way distillate combusts is that the lighter fraction will burn first. So the spark ignites and burns all the gas, which makes heat which burns the kero which makes heat to burn the diesel. The lower compression allows for this rather than it all trying to burn at one time, which will knock a...
