300 update and belt pulley starting question

I took a shim off the pinion shaft over the weekend since the
shaft I took out had one each of thick, medium and thin. The
one I had put in had the same with one extra thin one, so I took
that out and figured I would see if that helped with the noise or
not. Today I got everything back together enough to make a test
run but the tractor would not start at first and then the starter
quit. The relay clicks and the output side of the relay has 12
volts when I push the button but the starter does not roll over. I
knew it was not the best so this was not a huge surprise. I am
wondering if I should send it out to be rebuilt or buy a rebuilt
one off this site or buy a new one off ebay? In the meantime I
want to get the 300 running to see if the sound is still there so I
am thinking that tomorrow I will try starting it with the Allis C
and a flat belt. I have never done this before so I am wondering
how to do it for best results. I know I need to put a twist in the
belt so the engines are both turning the right way. I am thinking
that I should block the clutch on the 300 and put the belt pulley
in gear, start the belt running on the C and then get back on the
300 and engage the clutch, start the engine and then reverse the
process to get the belt off again without grinding any gears. Is
this an okay way to do it or is there a better way? Any advice will
be much appreciated.

I don't know about the belt starting procedure but I would get the starter rebuilt by someone local. You should be able to find someone word of mouth around your area and if you are going to mess around with these old tractors he'll be a guy you'll want to get to know. Good Luck

That's the best way with one person. A lot handier if you can use two people, but that's not always possible. You will want to feather the clutch on the 300 so the belt doesn't come off the pulleys trying to start spinning the motor.

Zach, I dunno about 300's, but on my ol' H the starter sometimes locks up. Then I either crank the engine a tad or I unbolt the starter and re-attach it. Could the 300 be the same problem? Good Luck!

Zach, Yes you can probably start your 300 with a belt and another tractor. First put the 300 pully in gear and then block the clutch. Then get the belt as tight as you can with a twist. Start running the belt as slow as the pulling tractor can run. Then get on the 300 and really feature the clutch or the belt will come off. Once the tractor starts, put in the clutch and shift the pully out of gear. I start my W30 once or twice a year this way and I always seem to have the belt come off once or twice before I get it started. Al

Thanks, that sounds good. I'm mostly by myself when working so it is good to have a way to do it alone.
Zach

Yes, there is a local guy who does them and I will take it to him and ask about it. I am not totally sure if he does things this old but probably he would.
Zach

I thought about that and did end up cranking the engine for a while but was not able to get it to start. I pulled the starter out and looked at it but I was not able to see anything physically wrong with it.
Zach

Thanks very much. I like the picture. I will do as you described. I am hoping the C will be able to turn it over fairly easily. My belt is a lot shorter than yours but it is long enough to reach both tractors.

Zach, I've had the same problem with starters here and there and it's usually the copper contactor disc inside the solenoid. It gets arc damaged over time and combined with a little corrosion it will stop working. Remove the phenolic cover on the solenoid and you will see the copper disc. It can be filed or sanded smooth. If it's particularly worn you can sometimes turn them 90 degrees and get more life.

It's "feather" the clutch, not "feature" it.

By feathering it, means to VERY SLOWLY engage it.

Even when I proof read my responses, I sometimes still make a spelling error. Al
