A couple more questions.

Postby LRiddle » Tue Mar 15, 2016 11:07 am

I got my voltage regulator working. Just needed cleaned and adjusted, and the guy only charged 5 bucks. Score. So my question is, does my system on my '51 have the cutout on it? It charges at 10 amps for a bit, then the gauge goes to zero. I'm assuming that it's the cutout shutting it down. It has the 3 position switch, not the 4.

Question 2, is there a good way to flush the cooling system without pulling the head off? The manual just says to use washing powder (?) And run the engine up to temperature. I've also seen on the forum about flushing the jackets using a wand with the head off, but I was thinking I could remove the radiator and flush it from underneath, but I don't know.

Last question, my oil pressure gauge isn't stock, it has dashes up to 75 psi instead of the style with the colored range for the needle to be in. The needle barely lifts off the left side. I pulled the oil filter cap and cranked the motor and I do get oil returning to the filter, so I assume it's fine so I'm not sure if it's a gauge issue or if I do have flow but not enough. I'm stumped on that one.

Thanks in advance for the advice.

The oil pressure regulator on the Cub is set at approximately 35 lbs.

Number of factors on engine oil pressure; worn engine, weight oil, engine/oil temperature. 10 or 15 lbs oil pressure would barely move the needle on a 75 psi gauge.

Suggest purchasing an oil pressure gauge designed for the Cub.

You have a regulator, it adjusts the amperage as needed. A cutout stops the generator from drawing power out of the battery when the tractor isn't running.

Ok, so it's normal for it to charge until full and then not charge until it's needed again? I am assuming that's what is going on, but I know nothing of generator systems.

Could be a regulator or a cutout. The regulator contains a cutout. The cutout or cutout portion of the regulator disconnects the battery from the generator when the battery voltage is higher than the generator. And connects the generator to the battery when the generator voltage is higher than the battery.

Awesome, thank you. Any thoughts on flushing the cooling system with the head on?

Someone recently posted a picture of one sold for flushing RV tanks for around $6-.

I've read quite a bit on the forum on it, but what I've found is methods with the head on. I was wondering if it'd be possible/advisable to do it from the bottom side by the bolster with the head on.

Yup. Do a bit more searching. Again, it's been discussed several times

Hi,
Your Cub that you had pics of in a post before has the voltage regulator below the generator. That is the newer system, which began in 1950. The cutout or relay was on top of the generator.
Here are pics of them in Cub owner's manuals. The older cutout or Relay is first below.
A 75 Lb. oil gauge doesn't work real well on a Cub, like Eugene said, they don't register much because Cubs don't have that much pressure. Here is the original type one at TM Tractor you can look at. The 4th one is the newer gauge with numbers that they started using in the mid 1950's. :)

Update: I got my new stock style oil pressure gauge in and now when I start it up the pressure jumps right up. So that was a good fix.

I also got a new ammeter and installed that, now it appears the system is working fine. Or at least, it was working fine, but now I can see that it is.

Next step is to flush the cooling system with the tips Eugene told me about and my little girl will be all ready for work this summer.

Thanks to all who gave me advice.

Hi,
Glad your new gauges work well, and the generator works.
Here is a tool for flushing the cooling system, that someone on here made. It goes on a garden hose, I guess. :)
