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...

Re: 40C All fuel running on 75% diesel
Hi, There is a slight difference in the shape of the piston top in an all-fuel v a straight gas. But the main difference is the addition of shutters in front of the radiator to give higher running temps. You get to eyeball the gage to not let it get too cold. These were thermosiphon up till the 420,...

Re: 40C All fuel running on 75% diesel
Hi, All fuel was Distillate. The leftover parts of petroleum distillation. As one boils the crude in a still, the temperature rises in between the fractions then steadies for each one. Gas, Naptha, kerosene, No1 fuel oil, Diesel. What they did was open a valve to each pipe in turn when the temp stea...

That is my thinking as well. So I would count on all the 6v bits being in trouble by now....

Re: Potential 420c Purchase
Hi, Easy. Hook up meter to battery and read voltage. Should be about 12.5 v. Start machine. Voltage drops from load then rise up to around 13.8 v. If not, then you know it isn't charging. The ignition issue may well be there is no resistor added into the line feeding the coil. That would make the co...
